Applied Sports Nutrition Practice
Assess athletes and build complete, sport-specific nutrition plans.
Goal of this chapter: Eleven chapters have supplied the physiology and the numbers. This one turns them into practice — how to assess an athlete you have just met, what to monitor and how often, how to diagnose a problem rather than guess at it, how to work with coaches and budgets and travel, and how to think across an athlete's whole development rather than one season. It closes with a six-case capstone covering the volume.

The Sports Nutrition Assessment Framework
Learning goal: Conduct a complete first assessment of an athlete and produce a defensible starting plan.
Every prescription in this volume assumes you know who you are prescribing for. This lesson builds the intake process that produces that knowledge, in an order that catches the serious things first.
1Safety and Medical Screening First
Before any performance discussion: diagnosed medical conditions, all medications including ayurvedic and herbal preparations, allergies, previous or current disordered eating, menstrual history where relevant, recent illness or injury, and age. This ordering is deliberate. Chapter 11 showed how often the important finding is medical, and an assessment that starts with macros can spend forty minutes optimising protein for someone who needed a referral in the first five.
2The Athlete and Their Sport
Sport, position or event, competitive level, current training week in detail, season phase, and upcoming fixtures or competitions. Chapter 7 through 9 established that the dominant effort duration determines almost everything downstream, so this section decides which chapter's numbers apply. Ask for the actual training week rather than the intended one — what they did last week, not what the programme says.
3Current Intake, Honestly Gathered
A detailed recall of two typical days and one competition day, including drinks, snacks, supplements and anything eaten at work or on the way home. Ask about it neutrally — athletes under-report when they anticipate judgement, and a food diary that has been curated is worse than useless because it looks like data. Ask what they eat when things go badly as well as when they go well; that is usually the more informative answer.
4Constraints and Context
Budget, who cooks, whether they live at home or in a hostel, travel patterns, work or study schedule, kitchen and storage access, religious and cultural dietary requirements, and family food patterns. Chapter 9 lesson 9 made the point that a plan violating any constraint gets quietly replaced. Gathering constraints is not administrative — it determines whether the plan will be followed, which is the only thing that determines whether it works.
5Objective Measures Worth Taking
Bodyweight, with a baseline taken properly per Chapter 5. Height for context. Where indicated and appropriate, a sweat rate test. Blood results if they exist, or a referral if the pattern suggests iron, vitamin D or B12 testing. Be conservative with body composition measurement — it is frequently unnecessary, it carries the risks Chapter 11 lesson 6 described, and with adolescents it requires clear justification, consent and careful handling of the result.
6Turning It Into a Starting Plan
Set energy from bodyweight and training load, protein from the sport and phase, carbohydrate periodised to the training week, fat filling the remainder. Then translate every number into meals from the foods the athlete already eats, at their actual budget. State it in portions, not grams. And identify the one or two changes that will do the most — usually breakfast, or the post-training meal — rather than presenting a complete redesign that overwhelms.
7What to Say at the End of the First Meeting
Three things: what you are changing and why, what you want them to track, and when you will review it. Keep the changes to two or three. Set the review at three to four weeks, which is long enough for a signal and short enough to correct a mistake. And be explicit about anything you have referred and why, so the athlete understands it is a priority rather than a formality.
An assessment is a diagnosis, not an order form. A doctor who prescribed before examining would be negligent, and a practitioner who sets macros before screening is doing the same thing with lower stakes — usually. In two of the six capstone cases, the stakes were not lower at all.
- Medical: conditions, all medications, allergies, disordered eating history, menstrual history.
- Sport: event, position, level, real training week, season phase.
- Intake: two typical days plus a competition day, gathered neutrally.
- Constraints: budget, cooking, travel, schedule, culture.
- Measures: bodyweight baseline, sweat rate if indicated, bloods or referral.
- Plan: two or three changes, stated in portions, reviewed in three to four weeks.
Medical screening comes before performance discussion, every time. Conditions, medications, allergies, disordered eating history and menstrual history determine whether a nutrition plan is appropriate at all — and several of them mean referral before anything else.
An athlete arrives wanting a plan to gain 5 kg of muscle. What do you do before discussing a single macronutrient?
Answer: Screen — medical conditions, medications, disordered eating history, and for a female athlete, menstrual history. Then establish the sport, real training week and phase, current intake and constraints. The muscle-gain question is answerable only after those, and occasionally the screening changes the answer entirely.
- Medical screening comes before any performance conversation.
- Ask for the real training week and the real diet, gathered without judgement.
- Constraints determine adherence, which determines whether the plan works.
- Leave the first meeting with two or three changes and a review date.
Next: Lesson 12.2 covers what happens between reviews.
Nutrition Monitoring & Adjustment
Learning goal: Choose monitoring measures an athlete will actually maintain, and adjust from them without over-reacting.
A plan is a hypothesis. Monitoring is how you find out whether it was right, and adjustment is what you do about it. Both fail more often through excess than through neglect.
1Monitor Few Things, Consistently
Asking for six daily measures guarantees none are recorded after a fortnight. Choose three or four that the athlete will maintain: morning bodyweight, a simple daily readiness or soreness rating, training load or session quality, and sleep hours. Add sport-specific markers where they exist — a repeated sprint time, a standard session pace, a key lift. Consistency over months beats precision over a week, because the signal you are looking for is a trend.
2Bodyweight, Used Properly
Weigh on waking, after urinating, before drinking, same clothing, same scale. Judge the seven-day average against the previous week rather than day to day — daily bodyweight moves with glycogen, food volume, hydration and menstrual cycle phase, and reacting to a single reading is the most common monitoring error. A change of less than roughly 0.5% of bodyweight over a week is noise for most athletes.
3Subjective Measures Are Underrated
A simple one-to-five rating of soreness, energy, sleep quality and motivation, recorded daily, tracks training stress and recovery well and costs nothing. Athletes are generally reliable reporters of their own state when the scale is simple and the habit is established. A run of falling readiness scores is often the earliest available signal that intake, sleep or load needs attention — earlier than bodyweight and far earlier than performance.
4When to Adjust and When to Wait
Give a change three to four weeks before judging it, unless something is clearly wrong. Adjust when the trend is consistent across at least two measures and persists beyond a fortnight. Do not adjust after one bad session, one heavy weekend, or one poor night's sleep. The discipline of waiting is harder than it sounds, and premature adjustment is how practitioners end up chasing noise and destabilising a plan that was working.
5How Much to Adjust
Small increments. For energy, 150–300 kcal at a time rather than 500. For carbohydrate, one tier of the system in Chapter 7 lesson 5. For protein, redistribution before addition. Large adjustments overshoot, obscure what caused the change, and unsettle the athlete. If a small adjustment does not move anything in three weeks, adjust again in the same direction rather than jumping.
6What Monitoring Is Not For
It is not for surveillance, and it should not become a source of anxiety. If an athlete is distressed by daily weighing, stop weighing daily — a weekly figure or none at all is preferable to a measurement that harms them. Chapter 11 lesson 6 applies directly: with adolescents and anyone with a disordered eating history, bodyweight and body composition monitoring may be inappropriate entirely, and readiness and performance measures serve instead.
7Reviewing With the Athlete
Show them the trend rather than the numbers — a line over eight weeks communicates what a table of daily readings does not. Ask what they actually did, not what they were supposed to do, since the gap between the two is the most useful information available. And close each review the way you closed the first meeting: what changes, what to track, when you will look again.
One further point about what to do with the data. Monitoring is only useful if it is actually looked at, and a surprising number of practitioners collect measures they never review. Set a fixed review point — the same day every month — and look at the trend even when nothing appears wrong, because the value of monitoring lies mostly in catching drift early. An athlete whose readiness scores have fallen gradually over six weeks will not report it as a problem; the trend line will show it before they do.
- Morning bodyweight, seven-day average.
- Daily readiness, soreness, sleep and energy on a 1–5 scale.
- Training load or session quality.
- One sport-specific performance marker where available.
- Review every three to four weeks; adjust only on consistent trends.
Myth: "More data means better decisions." Reality: Six measures produce no data after two weeks because nobody maintains them. Three measures maintained for six months produce the trend that actually informs a decision.
An athlete's bodyweight is 0.9 kg up on yesterday and he wants to cut calories immediately. What do you tell him?
Answer: Wait. Daily bodyweight moves with glycogen, food volume, salt and hydration — a single day's change of that size is almost certainly not fat. Judge the seven-day average against last week's, and adjust only if a consistent trend persists beyond two weeks.
- Three or four measures maintained beat six abandoned.
- Use seven-day bodyweight averages, never single readings.
- Adjust on consistent trends across two measures, in small increments.
- Stop any monitoring that causes distress — especially in young athletes.
Next: Lesson 12.3 turns monitoring into diagnosis.
Troubleshooting Common Nutrition Problems
Learning goal: Diagnose the actual cause of a performance or recovery complaint rather than guessing at a solution.
Athletes present with symptoms, not diagnoses. This lesson gives a systematic route from complaint to cause, which is the skill that distinguishes a practitioner from a plan.
1The General Diagnostic Order
For almost any complaint, check in this sequence: medical causes and referral indicators; total energy adequacy; sleep; training load and programming; protein total and distribution; carbohydrate relative to load; hydration; and only then anything more specific. This order reflects both frequency and effect size. Practitioners who start at the specific end spend a lot of time optimising the small levers of athletes whose large ones are broken.
2"I'm Always Tired"
The most common complaint and the one with the widest differential. Screen for medical causes first — iron deficiency, B12, thyroid, and in female athletes the RED-S picture from Chapter 11 — and refer if the pattern fits. Then energy adequacy, then sleep, then training load. In Indian athletes, iron deficiency and simple under-eating account for a large share of these presentations, and both are cheap to investigate.
3"I Fade Late in Sessions or Matches"
This points toward carbohydrate before anything else — Chapter 7 lesson 2's late-set collapse, Chapter 9 lesson 1's final-quarter decline. Check daily carbohydrate against training load, the pre-session meal, and in-session fuelling for anything over an hour. Then check total energy and sleep. Only after those consider caffeine timing or anything more exotic. A supplement question about late-session fatigue is nearly always the wrong question.
4"I'm Not Gaining Muscle" or "Not Losing Fat"
For gaining: check total energy first — most athletes who believe they eat a lot do not — then protein total and distribution per Chapter 4, then training programming. For losing: check energy honestly including drinks, oil and portion sizes, then protein for muscle retention, then rate of loss against the 0.5–1.0% weekly ceiling. In both directions, the answer is usually the total, and the athlete usually believes it is something else.
5"My Stomach Is a Problem in Races"
Work through Chapter 8's causes in order: untrained gut, drink concentration above roughly 8%, fat and fibre too close to the event, dehydration, and NSAID use. Then consider individual food intolerances, and refer if symptoms occur outside training too, since that changes the picture entirely per Chapter 10 lesson 5. Almost all race-day gut problems resolve within these five before anything is bought.
6"I Keep Cramping"
Two plausible mechanisms per Chapter 5: high sweat sodium losses, and neuromuscular fatigue. Check for salt crusting on kit, measure sweat rate, and look at whether cramps occur late in sessions and in the hardest-working positions or muscles. Test the sodium hypothesis with an ORS-strength drink over a few sessions; if nothing changes, the cause is more likely conditioning and load. Say honestly that the evidence here is genuinely mixed.
7When the Answer Is Not Nutrition
A substantial share of complaints brought to a nutrition practitioner are training, sleep, medical or psychological in origin. Recognising that quickly and saying so is more valuable than producing a nutritional explanation for everything. "I don't think this is a food problem, and here is what I think it is" builds more trust than a plausible-sounding macro adjustment, and it is what a competent practitioner does.
8When the Athlete’s Own Theory Is Wrong
Athletes arrive with a diagnosis already formed, usually borrowed from a teammate or the internet, and it is wrong often enough to be worth planning for. Two of the six capstone cases at the end of this chapter involve exactly that. Handle it by asking what they have already tried and what changed, which surfaces the theory without confronting it, then working the diagnostic order out loud so they can see the reasoning rather than simply receiving a verdict. An athlete who watches you rule things out in sequence usually accepts the conclusion even when it contradicts what they came in believing — and, more usefully, learns the sequence.
- Medical causes and referral indicators.
- Total energy adequacy.
- Sleep.
- Training load and programming.
- Protein total and distribution.
- Carbohydrate relative to load, then hydration, then specifics.
When a complaint arrives, I write down my three most likely causes before asking any more questions. It stops me anchoring on the first plausible explanation, and it makes it obvious when the athlete's own theory and mine differ — which is usually the most productive part of the conversation.
A footballer says he has no energy in the last 20 minutes and asks which pre-workout to buy. Walk through your diagnostic sequence.
Answer: Screen briefly for medical causes and fatigue patterns; check total energy and sleep; then daily carbohydrate against his match and training load; then his pre-match meal and in-match fuelling, since 90 minutes warrants 30–60 g. Late-match fade is a glycogen signature far more often than a stimulant deficiency, and a pre-workout would be the last thing considered, not the first.
- Work the same order every time: medical, energy, sleep, training, protein, carbs, fluid.
- Late-session fade points to carbohydrate; constant fatigue points to iron or energy.
- Race-day gut problems almost always resolve within five known causes.
- Saying "this isn't a food problem" is a competent answer, not a failure.
Next: Lesson 12.4 addresses the relationship that determines whether any of this is implemented.
Communication with Coaches
Learning goal: Work productively with coaches, including when you disagree with them.
The coach controls training, selection and usually the athlete's trust. A nutrition plan that the coach does not support will not survive, however good it is. This lesson is about making that relationship work.
1Understand the Coach's Position
Coaches are accountable for results, usually under-resourced, often working with limited or dated nutrition information, and frequently sceptical of specialists who arrive with recommendations that complicate their week. Approaching them as though their scepticism is ignorance guarantees failure. Approaching them as a colleague with a different remit, who wants the same outcome, generally works.
2Speak in Performance Terms
Coaches respond to performance language, not nutritional language. "Your midfielders are fading at 70 minutes and this is why" lands where "their carbohydrate intake is 4 g/kg" does not. Frame every recommendation in terms of what the coach already cares about — late-match output, recovery between fixtures, injury availability, training quality — and let the physiology sit underneath rather than on top.
3Start Small and Visible
Ask for one change that is cheap, easy and likely to show. The kit bag from Chapter 9, or fixing the post-match meal, or labelled bottles for the two players who cramp. A visible success buys the credibility to ask for more; an ambitious first request that fails costs the relationship. Pick the intervention where the coach has already noticed a problem, because then you are solving their problem rather than introducing yours.
4When You Disagree
Most disagreements are about weight, restriction, or a supplement the coach favours. Handle them privately, factually, and without undermining the coach in front of athletes. Bring evidence rather than authority, offer an alternative rather than only an objection, and be willing to lose the argument on genuinely debatable points. Preserving the relationship usually serves the athletes better than winning a marginal case.
5When You Cannot Compromise
Some things are not negotiable: weight cutting in minors, restriction in an athlete showing RED-S signs, supplements for adolescents, contamination-risk products for tested athletes, and anything overriding a doctor's instruction. On these, be clear, calm and specific about why, put it in writing, and involve parents where the athlete is a minor. If the coach proceeds anyway, document that you raised it. This is uncomfortable and it is the job.
6Respect the Boundary in Both Directions
Just as you expect the coach not to prescribe diets, do not prescribe training. Comment on training only where it directly bears on nutrition — load and recovery, session timing, weight-class planning — and frame it as a question rather than an instruction. Practitioners who drift into programming lose the standing to object when coaches drift into nutrition.
7Put It in Writing
A short written summary after any significant conversation — what was agreed, what you recommended, what you flagged — protects everyone and prevents the slow drift of a verbal agreement into something else. It is also what makes a disagreement resolvable later without either party relying on memory. Two or three lines by message is enough; this does not need to be formal to be useful.
A note on where you sit in the athlete’s wider system. Most Indian athletes are receiving input from a coach, a family member who cooks, a gym trainer, a senior player and often a doctor — and rarely are any of them talking to each other. You will not become the single authority, and attempting to be one usually fails. What works better is being explicit about which part of the picture you hold, asking what the others have said, and flagging conflicts rather than quietly overriding them. An athlete who understands who owns which decision is far less likely to follow whichever voice spoke most recently.
- Frame everything in performance terms.
- Start with one cheap, visible change to a problem they have already noticed.
- Disagree privately, factually, never in front of athletes.
- Hold firm on safety, minors, and doctor's instructions.
- Do not prescribe training; keep your own boundary.
- Summarise significant conversations in writing.
Weight cutting in minors, restriction in suspected RED-S, supplements for adolescents, and overriding medical instruction are not matters for compromise. Be clear, put it in writing, involve parents for a minor, and document that you raised it.
A coach tells the squad in front of you that carbohydrates make athletes slow and they should cut rice. How do you handle it?
Answer: Not in that moment and not in front of the squad. Raise it privately afterwards, in performance terms — late-match output and training quality depend on glycogen — and offer a specific alternative, such as keeping rice on match and hard training days and reducing it on rest days. Bring evidence, not authority, and follow up in writing.
- A plan the coach does not support will not survive.
- Speak in performance terms and start with one visible win.
- Disagree privately; never undermine a coach in front of athletes.
- Some things are non-negotiable — be clear, write it down, involve parents.
Next: Lesson 12.5 turns to teaching the athlete rather than instructing them.
Building Athlete Nutrition Literacy
Learning goal: Teach athletes to make their own decisions rather than depending on your instructions.
An athlete who follows a plan is dependent on you being there. An athlete who understands the reasoning can adapt at an away fixture, in an exam week, or five years after you stop working together. The second is the actual goal.
1Teach Principles, Not Prescriptions
"Eat 250 g of rice" is a prescription. "Carbohydrate fuels your hard sessions, so it goes up on match days and down on rest days" is a principle, and it generates the right answer in situations you never discussed. Every plan should come with the two or three principles behind it. Athletes remember principles longer than numbers, and they can apply them when the situation changes — which it always does.
2Three Things Every Athlete Should Understand
First, that total energy and protein do most of the work, and timing and supplements are refinements. Second, that carbohydrate should track training load. Third, that hydration and sodium needs are individual and measurable. An athlete who genuinely holds those three can construct a reasonable plan for any situation, evaluate most advice they encounter, and avoid the majority of expensive mistakes.
3Teach Them to Evaluate Claims
Chapter 10 lesson 1's questions, simplified: who was studied, was performance actually measured, how big was the effect, and who benefits if this is true. Athletes encounter nutrition claims constantly — from teammates, coaches, social media, shop staff — and equipping them to filter these does more good over a career than any individual plan. This is also the direct bridge into Volume 12, which builds the skill properly.
4Practical Skills Worth Teaching
Reading a supplement label for protein per serving and cost per 10 g. Estimating portions by hand and bowl rather than by scale. Knowing the protein content of six or seven foods they eat regularly. Recognising their own dehydration signs. Knowing what a proper recovery meal looks like from a station canteen. These are small, concrete competencies, and an athlete who has them is largely self-sufficient.
5How to Teach It
Little and often beats a single long session. Attach a principle to a moment that already exists — explain the recovery window while handing out the post-match food, not in a classroom. Use the athlete's own data: showing them their own sweat test result teaches individual variation better than any lecture. And repeat the same few messages consistently rather than covering everything once.
6Teaching Squads
For teams, short repeated messages work and long sessions do not. A five-minute point at the end of a training session, a single sheet on the dressing room wall, a rule stated at each season transition. Involve senior players — a squad's habits are set more by what respected teammates do than by what a visiting practitioner says. And feed people while you talk to them; the practical demonstration lands better than the explanation.
7The Test of Whether It Worked
Ask an athlete, three months in, what they would eat before a 7 am fixture, or how they would adjust on a rest day, or what they would do if the venue had no food. If they can reason to a sensible answer rather than recalling an instruction, you have built literacy. If they say "you told me to have poha", you have built dependence — which is a comfortable position for a practitioner and a poor outcome for the athlete.
8What Not to Teach
Some things are worse than useless to pass on. Do not teach calorie counting to adolescents or to anyone with a disordered eating history — the cost of the habit exceeds its accuracy. Do not teach food categorisation into good and bad. Do not teach reliance on tracking apps whose database entries for Indian foods are frequently wrong by wide margins, and whose expenditure estimates are worse. And do not teach rules so rigid that a family meal or a festival becomes a failure. Literacy is meant to make an athlete more flexible, not more anxious, and a teaching approach that produces rigidity has failed regardless of how accurate its content was.
The goal is an athlete who can construct a reasonable plan without you. Teach the principle behind every prescription, and test understanding by asking them to reason through a situation you never covered.
Athletes remember three principles far longer than thirty instructions — and the three principles generate correct answers in situations the thirty instructions never anticipated.
Three months into working with an athlete, how would you test whether you have built literacy rather than dependence?
Answer: Pose a situation you never covered — an away fixture with a 6 am start and no catering, say — and ask what they would do and why. Reasoning to a sensible answer from principles shows literacy; recalling an instruction, or having no answer at all, shows dependence.
- Teach the principle behind every prescription.
- Three principles — energy and protein first, carbs track load, hydration is individual — cover most situations.
- Teach claim evaluation; athletes face nutrition claims constantly.
- Test by asking them to reason through a situation you never discussed.
Next: Lesson 12.6 addresses the constraint that shapes most Indian athletes' nutrition.
Budget-Conscious Nutrition
Learning goal: Build a complete athlete diet at a realistic Indian budget, and know what to sacrifice first when money is short.
Most athletes reading this course are not funded. Budget is not a secondary consideration to be accommodated — for the majority it is the primary constraint, and a practitioner who cannot work within it is not much use.
1The Cost-Efficiency Table
Protein per 10 g, approximately: soya chunks ₹3, dal ₹8–10, eggs ₹12–14, chicken ₹12–13, milk ₹15–18, paneer ₹20–25, whey ₹28–35. Carbohydrate is cheap across the board — rice, roti, poha, potato, banana. The expensive items in most athletes' shopping are supplements, processed foods, and out-of-home eating, none of which are nutritionally necessary. This table alone resolves most budget problems.
2Three Complete Budget Tiers
₹150/day: soya chunks twice daily, eggs at breakfast, dal, rice, roti, curd, seasonal vegetables, banana. Reaches roughly 150 g protein for a 75 kg athlete with adequate carbohydrate. ₹250/day: add chicken or fish three or four times weekly, paneer, milk, more fruit. ₹400/day: add daily animal protein, nuts, more variety, and whey if convenience genuinely requires it. The important finding is that the first tier is nutritionally adequate — the others buy variety and convenience, not results.
3What to Cut First When Money Is Short
In order: all supplements except creatine if it is being used; out-of-home eating and packaged snacks; expensive protein sources replaced by soya, eggs and dal; variety, which costs money and matters least; and only last, total quantity. Protecting total energy and total protein while sacrificing variety and convenience is almost always the right trade. An athlete eating the same four meals repeatedly at adequate quantity will outperform one eating varied meals at inadequate quantity.
4Seasonal and Local Buying
Seasonal fruit and vegetables cost a fraction of out-of-season produce and are usually better. Local staples — ragi in Karnataka, bajra in Rajasthan and Gujarat, coastal fish where available at ₹180–300/kg — are cheaper than imported equivalents and often nutritionally superior to the products marketed as their replacements. Buying dal, rice, soya and chana in bulk reduces cost meaningfully for a household or a hostel.
5Squad and Household Economics
Cooking for a squad or family is substantially cheaper per person than individual portions, and bulk purchase amplifies that. For academies and clubs, the Chapter 9 lesson 9 approach — a plate model, a standing order with local vendors, a stocked snack table — delivers adequate nutrition at roughly ₹250 per player per day. For a student athlete living at home, the highest-yield conversation is often with whoever cooks rather than with the athlete.
6What Poverty Actually Costs Athletically
Be honest about this rather than pretending budget is always solvable. An athlete who genuinely cannot afford adequate energy will not perform, and no amount of clever food selection fixes an insufficient food budget. Where that is the situation, the useful actions are practical — identifying the cheapest adequate options, involving the academy or club, and being clear with coaches that the athlete's limitation is not effort or discipline. Framing an under-fed athlete as unmotivated is both wrong and harmful.
7The Recurring Message
Across this whole volume, the interventions that changed outcomes were overwhelmingly cheap: eggs and soya chunks, a ₹120 kit bag, ORS at ₹22, an extra hour of sleep, a redistributed protein intake, a blood test. The expensive things — the stacks, the blends, the powders — changed almost nothing. That is not a moral position about spending; it is what the evidence in the preceding eleven chapters actually showed.
One more practical route worth knowing: many Indian athletes eat at least one daily meal from a mess, canteen or roadside vendor rather than a home kitchen, and the useful skill is choosing well within a fixed menu rather than designing an ideal one. Rice with dal and curd, egg curry, chana, rajma, idli with sambhar and plain rotis are almost universally available and adequate. Teaching an athlete the three best options at the places they already eat is more valuable than a meal plan requiring a kitchen they do not have.
- Establish the real daily food budget before designing anything.
- Anchor protein on soya chunks, eggs and dal.
- Fill carbohydrate with rice, roti, poha, potato and banana.
- Cut supplements, out-of-home eating and variety before quantity.
- Buy seasonal and local; buy staples in bulk.
- For squads and families, cook collectively and order standing.
A complete athlete diet reaching 150 g of protein and adequate carbohydrate is achievable at roughly ₹150 a day in India — less than a single serving of many imported supplements.
A 70 kg athlete has ₹180 a day for food and currently spends ₹120 of it on a protein powder. What is your first move?
Answer: Stop the powder and redirect the whole ₹180 to food. At soya chunks ₹3 and eggs ₹12–14 per 10 g of protein, that budget comfortably covers 130–150 g of protein plus adequate rice, roti and vegetables — whereas the powder was consuming two-thirds of his food money for perhaps 30 g.
- A complete athlete diet is achievable at roughly ₹150 a day in India.
- Cut supplements, eating out and variety before ever cutting quantity.
- Soya chunks, eggs and dal are the backbone of budget sports nutrition.
- An under-fed athlete is not an unmotivated one — say so to coaches.
Next: Lesson 12.7 covers the period when nutrition matters most and is handled worst.
Injury Recovery Nutrition
Learning goal: Support tissue healing and limit muscle loss through an injury layoff.
Chapter 6 lesson 8 introduced this. It gets a full lesson here because injury is when athletes most reliably do the wrong thing, and because the consequences persist long after they return.
1The Instinct That Costs Them
Almost every injured athlete cuts food, reasoning that they are burning less. Three things make this wrong: disuse causes rapid muscle loss, injured tissue is anabolically resistant so it responds less to the same protein, and healing itself carries an energy cost. An aggressive deficit during a layoff accelerates muscle loss while slowing repair — the exact opposite of the athlete's intention.
2The Prescription
Raise protein to 2.0–2.5 g/kg, in per-meal doses large enough to clear the leucine threshold, and reduce energy only modestly — typically 200–400 kcal below their training baseline, not the 800–1,000 athletes often impose. Maintain carbohydrate adequate for whatever rehabilitation work is being done. Accept a small amount of fat gain as the price of preserving muscle, and say so explicitly at the start so it does not become a crisis in week three.
3Nutrients With a Role in Healing
Protein above all. Vitamin C for collagen synthesis. Zinc for tissue repair. Adequate energy generally. For tendon and ligament involvement, the collagen-plus-vitamin-C strategy from Chapter 6 lesson 6 — roughly 15 g of gelatin or collagen with a vitamin C source about an hour before rehabilitation loading. Omega-3s may help the inflammatory balance. None of these accelerates a timeline set by tissue biology and the physiotherapist, and they should not be presented as though they do.
4Loading Is Still the Primary Stimulus
Nutrition supports repair; mechanical loading drives it. Whatever rehabilitation the physiotherapist permits is the main intervention, and the nutritional strategies above are timed around it. An athlete taking collagen while avoiding all loading of the injured tissue is doing the ineffective half. Similarly, maintaining resistance training for uninjured parts of the body preserves muscle and morale, and is usually possible with a limb injury.
5The Psychological Dimension
Injured athletes commonly experience low mood, loss of identity and anxiety about weight, and these interact with eating in both directions — restriction, or comfort eating and guilt. Chapter 11 lesson 6 applies: keep language neutral, frame food as part of healing rather than as something to be controlled, and refer where distress is significant or restriction appears. An injury layoff is one of the higher-risk periods for disordered eating to begin.
6Returning to Training
Energy needs rise again before appetite and habits catch up, and anabolic resistance from the layoff takes time to reverse. Hold protein at the elevated 2.0–2.2 g/kg through the early return, restore carbohydrate as load returns, and expect strength to lag size. The common error is an athlete who ate well through the injury and then under-eats during the return because of the fat they gained — precisely when the tissue is most ready to rebuild.
7What Belongs to Others
Diagnosis, rehabilitation programming, pain management and return-to-play decisions all belong to the medical and physiotherapy team. Nutrition supports their plan. Where an athlete asks about painkillers, refer — Chapter 6 lesson 3 noted that routine NSAID use may blunt adaptation and carries medical risk, but the decision is a doctor's. Coordinate rather than operating in parallel; the physiotherapist knows what loading is permitted and when, which is what the collagen timing depends on.
8Surgery and Immobilisation
Where an injury involves surgery, the demands rise further: surgical wounds have their own healing cost, immobilisation accelerates disuse loss, and appetite is often suppressed for several days afterwards. The nutritional priorities are unchanged in kind but sharper in degree — protein at the top of the range, adequate energy, vitamin C and zinc adequacy, and small frequent meals while appetite is poor. Everything else, including when loading may resume and what the wound needs, belongs to the surgical and physiotherapy team. Ask what they have permitted rather than assuming, since the answer changes week to week and the collagen timing depends on it.
Diagnosis, rehabilitation, pain management and return-to-play belong to the medical and physiotherapy team. Nutrition supports their plan. Refer any question about painkillers, and refer promptly if the athlete shows significant low mood or restrictive eating during the layoff.
Rahul, 26, footballer, Kochi, eight weeks out with a hamstring tear. Instinct was to drop to 1,500 kcal. Revised to a 300 kcal reduction with protein raised from 1.7 to 2.3 g/kg, upper-body and uninjured-leg training maintained, collagen with amla timed before rehab sessions. Returned 1.2 kg heavier in fat but with thigh circumference and single-leg strength close to baseline — against a previous layoff where he lost noticeable muscle.
An athlete six weeks into a knee injury has cut to 1,400 kcal and 80 g of protein at 72 kg, and is distressed about weight gain. Name the three problems and what you would do about the third.
Answer: Protein at 1.1 g/kg is far below the 2.0–2.5 g/kg an injury requires; the deficit is far steeper than the modest reduction appropriate during healing; and the distress about weight is itself a risk factor for disordered eating during a vulnerable period. For the third, keep language neutral, frame food as part of healing, and refer if the distress is significant or restriction continues.
- Injury calls for more protein and only a modest energy reduction — never a cut.
- 2.0–2.5 g/kg, with collagen and vitamin C timed around permitted loading.
- Loading drives repair; nutrition supports it.
- Layoffs are a higher-risk period for disordered eating — watch and refer.
Next: Lesson 12.8 covers keeping a plan alive on the road.
Travel Nutrition Maintenance
Learning goal: Maintain nutrition standards across the travel that dominates an Indian competitive season.
Chapter 9 lesson 8 covered squad travel. This lesson takes the individual athlete's perspective and the longer view: not one journey, but a season of them.
1The Three Risks, Ranked
Illness first — a gastrointestinal infection removes an athlete from a competition entirely, which outweighs any fuelling gain. Dehydration second, driven by air conditioning, restricted drinking to avoid toilet stops, and heat at the destination. Under-fuelling third. Ranking them this way changes the priorities: food safety decisions come before macronutrient decisions on the road, which is the reverse of the usual order.
2Food Safety Rules Worth Memorising
Sealed bottled or properly boiled water where supply is uncertain. Hot, freshly cooked food rather than food that has been standing. No raw salads, no pre-cut fruit from stalls, no ice of unknown origin. Fruit the athlete peels themselves. Busy places over empty ones, since turnover means fresher food. These are unglamorous and they are what keeps an athlete available.
3The Personal Travel Kit
Assume nothing suitable will be available when needed. A workable personal kit at roughly ₹150–250: bananas, dates, roasted chana, theplas or plain parathas that keep, chikki, ORS sachets, sealed water, and a protein source that travels if one is affordable. Theplas are a standard Indian travel food precisely because they last — using existing food culture works better than importing a foreign template.
4Managing Long Journeys
Eat at intervals rather than at whatever stop appears — something every three hours, fluid steadily throughout. Move at breaks. For overnight travel, prioritise sleep over eating and plan a substantial meal on arrival instead. And build in the arrival plan before departure: knowing where the first proper meal is coming from prevents the common pattern of arriving at 11 pm and eating whatever is open.
5At the Destination
Rehydrate with sodium first, then a carbohydrate-rich familiar meal, then sleep. Identify meal sources for the whole stay on day one. Where a hotel or venue caters, send a short written list in advance — plain rice, dal, curd, boiled eggs, fruit, less oil — which works far better than negotiating at the buffet. Weigh on arrival if a baseline exists, since travel dehydration is routinely underestimated.
6Across a Season
A single trip handled badly costs little; twenty handled badly costs a season. The athletes who manage this well have a fixed routine — the same kit, the same rules, the same arrival sequence — rather than improvising each time. Building that routine once, early in the season, is a better use of a consultation than troubleshooting each trip individually. Track morning bodyweight through travel-heavy periods, since cumulative deficits show up there first.
7If Illness Happens
Fluid and electrolytes first — ORS is exactly right — with small amounts of bland familiar food as tolerated: khichdi, curd rice, banana, plain toast. Do not push training or competition. Fever, blood in stool, persistent vomiting or inability to keep fluids down need a doctor promptly, and an athlete with fever should not compete regardless of what is at stake. That last point frequently needs stating to a coach rather than to the athlete.
8The Athlete Who Travels Alone
Individual-sport athletes — runners, cyclists, swimmers, shooters — often travel without a squad, a manager or anyone whose job includes their food, and everything in this lesson falls to them personally after an early start and a long journey. For these athletes the routine matters more, not less, and it should be written down rather than remembered: a packing list, three food-safety rules, the arrival sequence, and a plan for the pre-competition meal that does not depend on the venue. Build it once with them and review it after the first two trips, adjusting around whatever actually went wrong rather than around what you predicted would.
Fever, blood in stool, persistent vomiting or inability to keep fluids down require medical attention. An athlete with fever must not train or compete — the cardiac risk is real, and no fixture is worth it.
- Sealed or boiled water; hot freshly cooked food only.
- Personal kit: bananas, dates, chana, theplas, ORS, sealed water.
- Eat every three hours on long journeys; fluid steadily.
- Plan the arrival meal before departure.
- Send hotels a written food list in advance.
- Use the same routine every trip; track morning weight in heavy travel periods.
An athlete has eight away fixtures this season and asks how to eat on the road. What do you build with her, and why is that better than advising trip by trip?
Answer: Build one fixed routine — the same kit list, the same food-safety rules, the same arrival sequence — that she applies unchanged to all eight. A routine survives fatigue, delays and unfamiliar venues, whereas trip-specific advice has to be remembered and re-decided each time, which is exactly when it fails.
- Rank the risks: illness, dehydration, then under-fuelling.
- Food safety decisions come before macronutrient decisions on the road.
- Carry a fixed personal kit; assume nothing suitable will be available.
- Build one routine for the season rather than advising trip by trip.
Next: Lesson 12.9 covers the environments that break plans entirely.
Altitude, Heat, and Extreme Environments
Learning goal: Adjust nutrition for altitude, heat, cold and humidity, and recognise the environmental emergencies that outrank nutrition entirely.
India spans Himalayan altitude, coastal humidity, desert heat and Himalayan winter, and athletes move between them within a season. This lesson consolidates the environmental adjustments from Chapters 5, 8 and 9.
1Heat and Humidity
The core adjustments: measure sweat rate in the conditions that matter, match sodium concentration to duration and salt crusting, cool actively because in humidity cooling beats drinking, and acclimatise over 7–14 days where the calendar allows. Expect reduced intensity and plan for it rather than treating it as underperformance. Humidity is more dangerous than temperature alone, because evaporation is what actually cools.
2Altitude
Resting metabolic rate rises while appetite falls, so athletes reliably under-eat and lose weight. Carbohydrate becomes relatively more valuable because it yields more energy per unit of oxygen. Fluid needs rise through respiratory losses in dry air, and thirst is unreliable. Iron status determines whether the red-cell adaptation can occur at all, which makes pre-camp ferritin testing the single highest-value action. Eat to schedule rather than appetite, and track morning weight daily expecting stability.
3Cold Environments
Less discussed in Indian sport but relevant for Himalayan training and winter fixtures in the north. Energy expenditure rises through shivering and the cost of carrying heavier clothing. Dehydration is easy to miss because thirst is blunted in cold and athletes drink less when fluid is cold and toilets are inconvenient. Practical adjustments: warm fluids to encourage intake, deliberately higher energy intake, and eating at intervals since appetite cues are less reliable.
4The Common Thread
In every extreme environment, two things happen: energy requirements change, and the body's own signals become less reliable guides. Thirst under-reports in cold, at altitude and in older athletes. Appetite under-reports at altitude and after hot sessions. This is why every environmental recommendation in this volume defaults to scheduled intake and objective monitoring rather than to eating and drinking on demand.
5Planning a Move Between Environments
When an athlete moves — Shimla to Chennai, Delhi to Leh, coastal to desert — establish the destination conditions, begin whatever acclimatisation the calendar permits, re-measure sweat rate in the new environment rather than carrying over the old figure, take a bodyweight baseline on arrival, and adjust the plan rather than transplanting it. Data gathered in one environment does not transfer, and treating it as though it does is a common and consequential error.
6The Emergencies
Heat stroke: confusion, staggering, stopping sweating, vomiting, collapse — move to shade, cool aggressively, call emergency medical help. Acute mountain sickness: headache, nausea, breathlessness at rest, confusion — medical assessment and possibly descent. Hypothermia in cold environments — medical. None of these is managed with nutrition, and every squad operating in extreme conditions should have a written plan naming the symptoms, the immediate actions, who calls for help and where the nearest hospital is.
7Judging When Not to Compete
Occasionally the correct professional position is that conditions are unsafe, particularly for youth squads, and that a fixture or session should be moved or cancelled. That decision usually sits with administrators, and raising it may be unpopular. Raise it anyway, in writing, and push for the achievable middle ground — mandatory drink breaks, extended intervals, evening starts, shaded rest — where cancellation is not going to happen.
One point specific to the Indian calendar: many athletes fast for religious reasons at various points in the year — Navratri, Ramadan, Ekadashi and others — and this intersects with training in ways that deserve planning rather than argument. The practitioner’s role is not to advise against observance but to help the athlete train and recover within it: adjusting session timing where possible, concentrating intake in the permitted windows, protecting fluid and protein, and being alert to the fatigue and dehydration risks that a fasting athlete training in Indian heat genuinely faces. Where fasting coincides with heavy training or competition, involving the athlete’s doctor is appropriate.
Heat stroke, acute mountain sickness and hypothermia are medical emergencies. Recognise, act immediately on cooling or descent, and call for help. Have a written plan before the fixture, not assembled during it.
- Establish destination conditions and the fixture timing.
- Begin acclimatisation as early as the calendar allows.
- Re-measure sweat rate at the destination; do not carry old figures over.
- Take a bodyweight baseline on arrival and track daily.
- Adjust energy: up at altitude and in cold, with scheduled eating.
- Carry a written emergency plan for the conditions.
An athlete's sweat rate was measured at 1.2 L/hour in a Bengaluru winter. She is competing in Chennai in May. Can you use that figure?
Answer: No. Sweat rate is condition-dependent and can easily double between cool dry and hot humid conditions. Re-measure in Chennai-like conditions before building the plan, and in the meantime assume substantially higher losses with a correspondingly higher sodium concentration.
- Extreme environments change requirements and make the body's signals unreliable.
- Default to scheduled intake and objective monitoring, not thirst and appetite.
- Never transfer sweat rate data between environments — re-measure.
- Heat stroke, mountain sickness and hypothermia are emergencies, not nutrition problems.
Next: Lesson 12.10 takes the longest view in the volume.
Long-Term Athlete Development (LTAD)
Learning goal: Match nutrition to an athlete's developmental stage rather than only to their current season.
Every previous lesson optimised a week, a block or a season. This one asks what nutrition should look like across a decade, which changes several of the answers.
1The Stages, Broadly
Development models differ in detail but share a shape: early participation and fundamental movement in childhood; building capacity through adolescence; training to compete in late adolescence and early adulthood; peak performance years; and eventually transition out of competition. Nutrition's role differs at each. Applying peak-performance nutrition to a 13-year-old, or participation-stage indifference to a 24-year-old international, are both errors of stage rather than of knowledge.
2Childhood and Early Adolescence
The goals are growth, health, enjoyment and building normal food habits. Nutrition should be unremarkable: enough food, varied, eaten socially, without restriction, monitoring, supplements or body-composition discussion. This is the stage where lifelong relationships with food are formed, and where the damage done by weight-focused adult attention is greatest. The best nutrition intervention for a 12-year-old athlete is usually to leave their eating alone and make sure there is enough of it.
3Mid to Late Adolescence
Training load rises and growth continues, so requirements are at their highest relative to body size. This is where the Chapter 11 lesson 2 principles apply: ensure enough, fix breakfast and post-training food, no supplements by default, no weight targets, and a lower referral threshold. It is also the stage to begin teaching principles rather than issuing instructions, since a 17-year-old who understands why is equipped for the next decade.
4Peak Performance Years
This is where the rest of this volume applies in full — periodisation, precise targets, competition strategy, considered supplementation. It is also the stage where the marginal gains are worth pursuing because the fundamentals are usually established. The risk here is different: over-optimisation, chasing small levers while sleep or total energy quietly slip, and accumulating supplement spending that displaces food.
5Masters and Transition
Chapter 11 lesson 3 covers masters athletes. The transition out of competitive sport deserves a mention because it is handled badly so often: training volume falls sharply while eating habits persist, and athletes gain weight and interpret it as a metabolic change rather than an energy-balance one. Anticipating that transition and adjusting intake deliberately is a genuinely useful conversation, and almost nobody has it with athletes before it happens.
6What Should Never Change
Across every stage: adequate energy for the demands being placed on the body, protein sufficient for repair, food that fits the person's culture and budget, and a neutral relationship with eating. These are the constants. The variables are precision, periodisation and the degree to which nutrition is actively managed — and the mistake in both directions is applying the wrong degree of management for the stage.
7The Practitioner's Longest Contribution
The most valuable thing you can leave an athlete is not a plan for this season. It is a working understanding of how energy, protein, carbohydrate and hydration relate to what they are doing, a neutral relationship with food, and the habit of asking who was studied and what was measured before believing a claim. Those three persist for decades and across sports, coaches and circumstances — and they are what Volume 12 builds on.
8The Career the Athlete Actually Has
Most athletes reading this course will not become professionals, and development models written for elite pathways fit them poorly. A club cricketer who plays until he is forty-five, a recreational runner who wants to keep running at sixty, a corporate footballer with two fixtures a month — these are the majority, and their nutritional goal is sustained participation and health rather than a peak. That reframing changes the advice: less periodisation, more consistency; less optimisation, more habit; and considerably more attention to the things that keep someone in sport for decades, which are enjoyment, availability and not getting injured.
Match the degree of nutritional management to the developmental stage. A 12-year-old needs enough food and no attention on their body; a 24-year-old international needs periodisation and precision. Applying either to the other is the error.
Through childhood and adolescence: no restriction, no weight targets, no body composition discussion, no supplements by default, and a lower referral threshold for growth, menstrual and disordered eating concerns. These are the stages where harm lasts longest.
A 13-year-old's parents ask for a detailed macro plan with body composition targets to prepare her for a state trial. What do you offer instead?
Answer: Decline the composition targets and the detailed macros. At her stage the goals are growth, health and normal food habits — ensure enough food, varied, eaten socially, with breakfast and post-training meals covered. Explain that body-composition attention at 13 carries real risk and offers nothing she needs, and that the useful preparation is being well fed and well rested.
- Match management intensity to developmental stage, not to ambition.
- Childhood and early adolescence: enough food, no attention on bodies.
- Peak years are where full periodisation and precision belong.
- The lasting contribution is understanding, neutrality and claim evaluation.
Next: Lesson 12.11 integrates the whole volume.
Chapter Revision & Integration
Learning goal: Hold Volume 5 as a single connected framework rather than twelve separate chapters.
This revision covers the whole volume, not only this chapter, because the capstone that follows requires all of it.
1The Volume in One Chain
Protein supplies the material for adaptation, and total plus distribution do nearly all the work (Ch 4). Hydration and sodium are individual and measurable, and both under- and over-drinking carry risk (Ch 5). Recovery is where adaptation actually happens, and sleep outranks everything nutritional (Ch 6). Strength athletes are limited by force production, so creatine and adequate carbohydrate matter (Ch 7). Endurance athletes are limited by fuel, so glycogen strategy and absorption capacity matter (Ch 8). Team athletes combine both under logistical constraint (Ch 9). Supplements are a short list of modest effects surrounded by noise (Ch 10). The numbers came from young men and fit others poorly (Ch 11). And this chapter turns all of it into assessment, monitoring, diagnosis and communication.
2The Numbers That Carry Most of the Volume
Protein 1.6–2.2 g/kg, 2.2–2.6 in a deficit, 0.4–0.55 g/kg per meal, 0.5–0.6 for vegetarian and older athletes. Carbohydrate 3–12 g/kg scaled to load. Fluid loss under 2% of bodyweight, sodium 300–1,000 mg/L by duration. Recovery 1.0–1.2 g/kg carbohydrate per hour when the turnaround is under eight hours. In-race carbohydrate 30–60 g/hour, up to 90 with glucose-fructose. Creatine 3–5 g daily, caffeine 3–6 mg/kg. Fat loss capped at 0.5–1.0% of bodyweight weekly.
3The Diagnostic Order
Medical causes and referral indicators, total energy, sleep, training load, protein total and distribution, carbohydrate relative to load, hydration, then specifics. This single sequence resolves the majority of presentations in this volume, and applying it consistently is more valuable than remembering any individual number.
4The Referral List
Menstrual disruption. Repeated stress injuries. Suspected RED-S or disordered eating at any age. Faltering growth or delayed puberty. Any diagnosed medical condition with dietary instruction. Suspected iron, vitamin D or B12 deficiency. Heat illness, altitude illness. Pregnancy, menopause and hormone therapy questions. Medication and anti-doping status questions. Persistent gastrointestinal symptoms outside training. Each belongs with a doctor.
5What the Volume Kept Saying
Four themes recurred in every chapter. Total energy and protein do most of the work. Sleep outranks anything purchasable. Individual measurement beats population averages, especially for sweat and sodium. And the constraint that actually binds is usually not the one the athlete asked about — which is why the diagnostic order exists.
6What the Volume Does Not Settle
Most research is in young men. Female, adolescent, masters, transgender and adaptive athlete data are all thin. Cramping mechanisms remain disputed. Effects of several Tier 1 supplements are less precisely dose-mapped than confident numbers suggest. Indian-specific research — on heat and humidity protocols, on fixture congestion, on supplement market quality — is largely absent, so several recommendations here are reasoned extrapolation rather than direct evidence. Saying so is part of practising honestly.
7Where This Leads
Volume 5 taught what to do. Volume 12 teaches how to know — evaluating research, detecting misinformation, assessing individuals, working within professional boundaries, and continuing to learn once the course ends. Several lessons here have gestured at those skills; the capstone that follows is the last exercise in applying this volume's content, and the bridge into applying judgement to material this course never covered.
Four themes carry the volume: energy and protein do most of the work; sleep outranks anything purchasable; measure the individual rather than trusting averages; and the binding constraint is rarely the one the athlete asked about.
- Screen medically before discussing performance.
- Establish sport, phase, real training week and real intake.
- Set energy, protein, carbohydrate, fat — then translate to portions and budget.
- Monitor three or four things consistently; review every three to four weeks.
- Diagnose in the fixed order; adjust in small increments.
- Refer early and often; teach principles, not instructions.
Without looking back: state the diagnostic order, and explain why energy sits so near the top.
Answer: Medical causes, total energy, sleep, training load, protein total and distribution, carbohydrate relative to load, hydration, then specifics. Energy sits near the top because inadequate total energy causes fatigue, poor recovery, muscle loss, hormonal disruption, bone loss and immune problems simultaneously — it produces almost every complaint in this volume, and it is the most commonly missed.
- One chain: material, fluid, recovery, then sport-specific application under constraint.
- One diagnostic order, applied every time.
- One referral list, used early rather than late.
- Honest limits: most of this came from young men, and Indian-specific research is thin.
Next: Lesson 12.12 is the capstone — six cases spanning the volume.
Capstone Assessment & 6 Case Studies
Learning goal: Apply the whole volume to six athletes, producing a defensible assessment, plan, monitoring approach and referral decision for each.
Work each case fully before reading the analysis: assessment priorities, the binding constraint, the plan, what you would monitor, and what you would refer. These six span the volume deliberately.
1Case One — Vikram, 27, Powerlifter, Ludhiana
Situation: 88 kg, hypertrophy block, eats 3,100 kcal with 230 g protein, 75 g fat, 320 g carbohydrate. Sets of 10 collapse by the fourth set. Sleeps seven and a half hours. Takes a pre-workout and BCAAs at ₹4,000 monthly. Binding constraint: carbohydrate. Protein is at 2.6 g/kg, above the useful ceiling; carbohydrate at 3.6 g/kg is below the 5–7 g/kg a hypertrophy block needs, which is exactly the late-set collapse signature (Ch 7). Plan: protein down to 175 g, carbohydrate up to 450 g, total energy up modestly for a surplus. Stop the BCAAs; keep or add creatine at roughly ₹180 a month. Monitor: seven-day bodyweight average, set-four load, readiness. Refer: nothing indicated.
2Case Two — Lakshmi, 19, Vegetarian Distance Runner, Coimbatore
Situation: 47 kg, 75 km weekly, no periods for 13 months, one stress fracture, eating roughly 1,700 kcal, coach says her build suits distance running. Binding constraint: not nutritional in the first instance — this is the RED-S picture (Ch 11), and it outranks everything else. Plan: refer to a doctor immediately, state plainly that amenorrhoea is not a training adaptation, and support increased energy as part of a medically-led plan rather than instead of one. Test ferritin and B12 given vegetarian status. Set no weight or composition target. Monitor: alongside the medical team, not independently. Refer: doctor now; raise the coach's framing separately.
3Case Three — Imran, 34, Club Footballer, Nagpur
Situation: 76 kg, three matches in eight days, fades badly in the third. Shared water cooler, post-match food bought on the way home, 90-minute journey. Sleeps six and a half hours. Binding constraint: recovery logistics (Ch 9) — no structured refuelling in the 24 hours after each match, so each successive match starts lower. Sleep is a close second. Plan: ₹120 kit bag eaten on the bus, a fixed post-match meal arranged in advance, labelled ORS-strength bottle if a sweat test justifies it, full carbohydrate on the day between matches. Protect a seventh hour of sleep. Monitor: morning weight across the eight days, third-match output. Refer: nothing indicated.
4Case Four — Sneha, 52, Recreational Badminton, Bengaluru
Situation: 70 kg, perimenopausal, plays three times weekly, no resistance training, protein 1.2 g/kg across five small meals, planning a 1,200 kcal diet. On amlodipine for hypertension with a doctor-advised low-sodium diet. Binding constraint: several converging (Ch 11) — anabolic resistance with small per-meal doses, a planned deficit during the menopausal transition, and no loading stimulus. Plan: protein to 1.9 g/kg in four feeds of 33–35 g; adequate rather than restricted energy; add resistance and impact training; test vitamin D. Sodium: her doctor's restriction stands — document her training and send the question back rather than adjusting. Monitor: weekly weight average, grip and session quality. Refer: doctor for bone health assessment and the sodium question.
5Case Five — Arjun, 16, Academy Cricketer, Mumbai
Situation: 57 kg, told by his coach to gain 8 kg before the season, coach has recommended creatine and a mass gainer. Lives in an academy hostel with fixed meals. Parents asking your advice. Binding constraint: stage, not nutrition (Ch 11, Ch 12 lesson 10). He is 16, supplements default to no, and an adult has set a body-change target for a minor. He also does not control his food supply. Plan: no supplements. Work with the academy for larger portions, eggs and milk at breakfast, and food after evening training. Protein 1.4–1.8 g/kg from food, gradual gain alongside normal growth. Monitor: growth trajectory and training quality, not body composition. Refer: discuss with parents; paediatrician if creatine is pursued later.
6Case Six — Preeti, 31, Triathlete With Type 1 Diabetes, Delhi
Situation: 58 kg, half-distance race in 12 weeks, currently 40 g/hour carbohydrate on the bike and cramping on the run. Manages insulin with her diabetes team. Asks you to set race fuelling and adjust her insulin. Binding constraint: two separate things. The fuelling is inverted (Ch 8, Ch 9) — too little on the forgiving discipline, too much attempted on the unforgiving one — and glucose-only above 60 g/hour exceeds absorption capacity. The insulin question is outside scope (Ch 11 lesson 8). Plan: 70–80 g/hour glucose-fructose on the bike, 40 g/hour on the run, gut training over eight weeks in brick sessions, sweat test for the cramping. Write the fuelling structure up and send it to her diabetes team for the insulin side. Monitor: brick session tolerance, weight change across long sessions. Refer: diabetes team, as a collaboration rather than a handover.
7What the Six Have in Common
In two of six the primary action was a referral. In one it was a refusal. In two the athlete's own theory of their problem was wrong. In one the correct answer required working alongside a medical team rather than independently. Exactly one was a straightforward macronutrient adjustment of the kind the earlier chapters describe. That distribution is the honest picture of applied sports nutrition practice, and it is the last thing this volume has to teach.
8A Seventh Case, Unmarked
Finally, one to work entirely alone, with no analysis provided. A 24-year-old female kabaddi player at a Haryana academy is vegetarian, lives in the academy hostel, trains twice daily, has irregular periods she describes as normal for her, has been told by a senior player to start a fat burner before the season, has ferritin that was tested two years ago and never followed up, is travelling for a five-day tournament in three weeks, and does not control her own food supply. Produce a full written response: assessment priorities in order, the binding constraint, what you would refuse outright, who else must be involved, the plan you would build within the hostel’s constraints, what you would monitor across the tournament, and the two or three principles you would teach her so that she can manage the next tournament without you. If you can do that coherently, this volume has done its job.
Full marks are not for matching the prescriptions. They are for: screening before prescribing, identifying the binding constraint rather than the presenting complaint, referring where referral was indicated, refusing where refusal was indicated, and stating what you would monitor and when you would review.
Lakshmi needed a doctor before any plan. Sneha needed her sodium question and bone health returned to her doctor. Arjun needed his parents involved. Preeti needed her diabetes team to hold the insulin decision. Recognising these is the competence this volume was building toward.
Across all six cases, which single assessment step would have identified the most serious issue fastest, and why is it first in the framework?
Answer: Medical screening — specifically asking about menstrual history, medical conditions and medications at intake. It surfaces Lakshmi's amenorrhoea, Sneha's hypertension and prescribed restriction, and Preeti's diabetes before any macronutrient conversation begins. It is first precisely because the most serious findings are usually medical, and a performance-led assessment can miss them entirely.
- Screen first; the most serious findings are usually medical.
- Identify the binding constraint, not the presenting complaint.
- Refer and refuse where indicated — both are competent practice.
- Only one of six cases was a straightforward macro adjustment. That is the real base rate.
Volume 5 complete. You can now assess an athlete, set energy and macronutrients for their sport and phase, build hydration and fuelling strategies from measurement rather than assumption, judge a supplement claim honestly, adapt all of it across the lifespan and across Indian conditions and budgets — and, as importantly, recognise the situations that belong to someone else.
