Chapter 9
Special Populations

Beginners

Learning goal: Design sustainable, confidence-building nutrition for someone starting resistance training.

Beginners (first 6–12 months of consistent training) have the highest capacity for rapid muscle gain—often 0.5–1.0 kg per month—because their nervous systems and muscles are highly sensitised to training stimulus. Poor nutrition can waste this window, but even basic nutrition frequently beats advanced strategies. Beginners are also most likely to abandon training due to poor habits or unmet expectations; sustainable, simple nutrition is more important than optimal nutrition.

1Starting point assessment

A beginner's nutrition plan begins with honest assessment: current weight, recent eating patterns, available time for food prep, food preferences, and budget. Do not start with extreme changes (cutting all sweets, meal-prepping 10 hours weekly, spending ₹10,000/month on supplements). Instead, identify one or two high-impact changes: "I will eat protein at every meal" or "I will stop drinking sugary drinks daily." Start with consistency before perfection. A beginner who eats 100 g protein daily and improves to 140 g over 6 months will have better adherence than someone who tries to jump to 180 g immediately and quits after 3 weeks.

2Protein targets for beginners

Beginners should aim for 1.6–2.0 g protein/kg body weight daily. At 65 kg, this is 104–130 g daily, achievable with: breakfast (2 eggs, 100 ml milk, 1 roti) = 20 g; lunch (100 g chicken or paneer, rice, dal) = 35 g; evening snack (100 ml curd, fruit) = 12 g; dinner (150 g fish or soy, roti, vegetables) = 35 g; total ≈ 100 g. This is not extreme and teaches the habit of protein distribution without requiring supplements or special foods.

3Training-nutrition timing for beginners

Beginners often obsess over post-workout nutrition timing, thinking it is critical. It is not. What matters is total daily intake and consistency. Eat a meal (any meal) within 1–2 hours of training and include protein and carbohydrate—a banana with peanut butter after training, or waiting until dinner at 7 pm if training finished at 6 pm, both work equally. Focus on habits (never miss protein at a meal, eat enough carbs to support training) before worrying about minute details.

4The first six months: fastest progress, loosest habits

A beginner gains strength faster in the first six months than at any later point, through a mix of neural learning and genuine tissue growth — and this is also the period when nutrition is least organised. The practical consequence is that a beginner does not need supplements, a tracking app or a rigid meal plan. They need three meals that each contain protein, enough total food that body weight is not drifting down, and sleep. Loading complexity onto someone in their first eight weeks is the most common reason they stop, and stopping costs far more than imperfect macros ever did.

There is a second reason to keep it simple. A beginner's rate of progress is not limited by dietary precision, so the return on precision is small. Adding thirty grams of protein to a breakfast that previously had almost none, and eating enough to hold weight steady, delivers most of the available benefit. Refinement is worth doing later, when progress slows and there is something genuinely left to gain from it — which for most beginners is somewhere past the six-month mark.

5A beginner's day built from ordinary Indian meals

Take a 60 kg beginner at 1.5 g/kg, so about 90 g of protein. Breakfast of three eggs or 150 g of paneer with two roti supplies roughly 25 g. Lunch of dal with rice or roti plus a bowl of curd adds about 22 g. An evening plate of sprouts or chana chaat contributes around 12 g. Dinner of chicken or rajma with roti and curd brings roughly 30 g. That totals close to 90 g on food the household already cooks, at somewhere around ₹150–200 for the day depending on city and whether meat is included.

What this arithmetic demonstrates is that the target is reachable on ordinary food at ordinary cost, without a single specialist product. It matters because beginners told they need a special diet usually abandon it inside a month, while beginners shown their existing plate with protein added to each meal usually keep going. The instruction "put a protein at every meal" is both easier to follow and close to as effective as anything more elaborate.

• Target 1.6–2.0 g protein/kg body weight daily.
• Make one or two high-impact changes, not a complete overhaul.
• Focus on consistency and building habits before optimisation.

Women and Female Athletes

Learning goal: Design muscle-building plans aligned with female physiology and address societal barriers.

Women can build muscle as effectively as men with appropriate training and nutrition, but face unique physiological and social constraints. Oestrogen's effects on muscle protein synthesis differ from testosterone's, but with adequate protein and progressive training, muscle-building capacity is substantial. Women also face barriers: societal pressure against visible muscularity, lower average starting strength, less available training education targeted to women, and menstrual-cycle effects on training performance and appetite. Effective nutrition for female athletes addresses these realities.

1Protein and training for female muscle growth

Protein targets are the same as for men: 1.6–2.2 g/kg daily. A 62-kg woman targets 99–136 g daily. Training should be progressive resistance (compound movements, 6–12 rep range, increasing weight or reps over weeks). Many women start with lighter loads or higher reps (12–15) thinking it will avoid "bulking up"; this undershoots stimulus. Progressive, challenging resistance (same as for men) is required for muscle growth. The fear of becoming too muscular is unfounded; visible muscle gain takes years and consistency, and most women pursuing realistic goals are pleased with modest muscle definition.

2Menstrual cycle and nutrition adaptations

The menstrual cycle creates natural fluctuations in appetite, strength, and training tolerance. The follicular phase (days 1–14) often sees better strength and lower hunger; the luteal phase (days 15–28) often brings increased hunger, fatigue, and reduced strength. Adapting nutrition and training to these patterns can improve adherence: higher training volume and intensity during the follicular phase, slightly higher carbohydrate and calories during the luteal phase to match increased appetite, and reduced intensity if fatigue is high. This is an optimisation, not a requirement; consistent training and nutrition across the cycle also work if the person prefers simplicity.

3Common missteps and solutions

Many women undershoot calories, thinking lower intake will prevent fat gain and keep them lean. This backfires: chronic undereating suppresses menstrual function, impairs recovery, and limits muscle growth. A woman in a surplus for muscle gain should expect modest fat gain (0.25–0.5 kg per month alongside muscle); this is normal and reversible with a later cut. Another misstep is doing excessive cardio while building muscle, which interferes with recovery. Limit cardio to walking and light cycling; prioritise resistance training. A third misstep is avoiding protein sources (eggs, dairy, meat) thinking they will cause fat gain; they will not if total calories are controlled.

4Iron, ferritin, and the fatigue that gets blamed on training

Iron deficiency is common among Indian women, through a combination of menstrual losses and a largely plant-based iron intake that absorbs poorly. Its symptoms — breathlessness on efforts that used to be easy, heavy legs, poor tolerance of hard sessions — are routinely attributed to weak conditioning or poor discipline. The useful move is a full blood count together with ferritin rather than a guess, because ferritin can be low while haemoglobin still reads normal, and a haemoglobin-only test therefore misses early depletion. Correcting a real deficiency changes performance more than any supplement in this volume.

Iron supplementation itself belongs with a doctor: unnecessary iron is harmful, and the dose depends on how depleted the athlete actually is. What can be done immediately and safely is absorption technique. Pair a vitamin C source with iron-containing meals — lemon over dal, amla, guava, capsicum, tomato. Keep tea and coffee at least an hour away from those meals, since both reduce non-haem iron absorption substantially. Do not take a calcium supplement with the same meal. None of this costs anything, and it meaningfully changes how much iron the athlete actually absorbs.

5Energy availability, and why a lost period is never a normal adaptation

Relative energy deficiency in sport describes what happens when intake chronically fails to cover training demand. The consequences reach well beyond performance: menstrual disturbance, reduced bone density and stress fractures, impaired recovery, disturbed sleep, low mood. The single most important thing to say plainly to an athlete or a coach is that losing periods is never a normal training adaptation. It is a medical finding, and it warrants referral to a doctor — ideally one with sports medicine experience — rather than a nutritional adjustment made alone.

In practice this presents in athletes carrying a large training volume while eating for a body-composition goal, often with training rising over the same weeks that intake falls. The earliest sign is rarely the missed period. It is more often that ordinary sessions feel disproportionately hard, sleep gets worse, a reliable lift stalls, and the athlete becomes unusually cold or run-down. Someone who recognises that cluster and asks about intake before the bone injury arrives has done the most valuable thing available in this whole area.

• Target 1.6–2.2 g protein/kg daily; same as for men.
• Use progressive resistance training with challenging loads.
• Adapt to menstrual cycle if desired, but consistency across the cycle works too.

Teenagers

Learning goal: Support muscle growth and bone development in adolescents.

Teenagers (ages 13–19) experience rapid bone growth and mineralisation, and muscle-building capacity is high once resistance training begins (roughly age 14+ with mature motor control). Nutrition during these years has lasting effects on bone density and metabolic health. A teenage athlete training for muscle gain should eat more total calories and protein than adults of the same weight because growth and development are energetically expensive. However, extreme dieting or supplement use at this age risks disrupting growth, hormonal development, and psychological health.

1Increased calorie and protein needs

A 15-year-old trainee needs more energy than an adult of the same weight due to growth. Add 300–500 kcal above adult maintenance during growth spurts. Protein target is 1.8–2.2 g/kg (same as adults, but the total calories from growth means this is often exceeded naturally). A 65-kg 15-year-old boy training for muscle might eat 2,800–3,000 kcal daily (vs. 2,400 kcal for an adult of the same weight at maintenance). This is not excessive eating; it reflects growth demand.

2Micronutrients for bone and development

Calcium and vitamin D are critical for bone mineralisation during the teenage years. Adequate intake (1,000–1,300 mg calcium daily, 600–800 IU vitamin D) supports peak bone mass, which has lifelong consequences. Milk, yoghurt, cheese, leafy greens, and fortified foods are good sources. Iron is important for teenage girls (especially those menstruating heavily), as iron deficiency impairs training capacity and wellbeing. Red meat, legumes, and fortified cereals are sources.

3Avoiding extreme measures

Teenagers should not engage in crash dieting, extreme supplement use, or unsafe practices. Hydration is critical; many teenage athletes underdink water. Adequate sleep (8–10 hours) is non-negotiable for growth and recovery. Focus on education: teach teenagers the "why" behind nutrition choices so they make informed decisions rather than following trends or peer pressure. A 16-year-old taught how protein supports muscle growth and bone health is more likely to prioritise it than one told "take this supplement because pros use it."

4Growth and training compete for the same calories

An adolescent is already building tissue before any training is added, so training raises a demand that is already elevated rather than creating it from nothing. Energy needs during a growth spurt can exceed those of a grown adult doing the same programme. When intake falls short, the consequences show up well outside the gym: stalled growth, repeated minor illness, injuries that arrive too easily, poor concentration at school, and irritability. Poor gym progress is often the last symptom anyone notices, not the first.

This is also why body-composition goals need handling cautiously at this age. Height gain frequently resolves what looked like excess weight, and a restrictive approach imposed in the middle of growth can do damage that outlasts the sport entirely. Where there is genuine medical concern about an adolescent's weight, that assessment belongs with a paediatrician who can see the growth chart, not with a coach working from appearance. The default position for a training teenager is adequate food at regular intervals.

5What should not be offered to an adolescent athlete

Performance supplements should not be given to under-18s. That includes creatine, pre-workout formulas and anything sold for fat loss. The long-term data in this age group is limited, the products are inconsistently manufactured and inconsistently labelled in the Indian market, and the athlete in front of you has far more available from food and sleep than from any of it. Nothing in this chapter should be read as a recommendation to supplement a minor; where a genuine deficiency is suspected, that is a conversation for a doctor and a parent together.

Two further practices deserve refusing outright: weight-class manipulation with deliberate dehydration before a weigh-in, and any framing that attaches an adolescent's self-worth to a number on a scale. Coaches and parents set the tone here more than anyone. A teenager who learns that eating supports performance carries that understanding into adult sport and adult life. A teenager who learns to restrict frequently carries that forward too, and the consequences are harder to undo than any training error.

• Increase calories by 300–500 above adult maintenance.
• Target calcium (1,000–1,300 mg) and vitamin D (600–800 IU) for bone.
• Prioritise education and avoid extreme dieting or supplements.

Older Adults

Learning goal: Build muscle and maintain function with age-appropriate training and nutrition.

Sarcopenia—age-related muscle loss—begins in the 30s and accelerates after age 60. Progressive resistance training and adequate protein can slow and sometimes reverse sarcopenia. Older adults (60+) can build meaningful muscle mass, though the rate is slower than younger people. Recovery takes longer, nutrition needs are different (higher protein, specific micronutrients), and injury risk requires careful programming. Resistance training for an older adult is not a cosmetic pursuit but a functional one: maintaining strength prevents falls, preserves independence, and improves quality of life.

1Protein and recovery needs

Older adults need 1.8–2.4 g protein/kg daily—higher than younger adults—because muscle-protein synthesis becomes less efficient with age; more protein is needed to trigger the same response. A 70-year-old at 65 kg should target 117–156 g daily. Recovery takes longer; a session that fatigues a 25-year-old for 24 hours may fatigue a 65-year-old for 48+ hours. Training frequency should be adjusted: 2–3 sessions weekly may be adequate instead of 4–5. Adequate sleep (7–9 hours) is critical; sleep deprivation impairs recovery far more in older than younger people.

2Injury prevention and micronutrients

Joint health is critical. Adequate protein supports connective tissue; adequate vitamin D and calcium support bone and reduce fracture risk. Omega-3 fatty acids (fish, flax) support joint inflammation management. Slow progression and conservative load increases prevent injury; a 65-year-old should increase load by 2.5 kg (not 5 kg) and take longer between intensity increases. Medical clearance before starting resistance training is wise, especially for anyone with a history of heart disease, high blood pressure, or joint problems.

3Realistic expectations and programming

An older adult training for 12 weeks might gain 0.5–1.0 kg lean mass (vs. 2–3 kg for a younger person). This is still meaningful: measured strength increases of 15–25%, improved balance and fall prevention, and increased independence. Programme design should emphasise function: squats for sit-to-stand ability, rows for posture, carries for grip and core strength. Accessory work should address weak areas (hips, ankles, shoulders). Group classes or training partners improve adherence.

4Anabolic resistance: bigger doses, spread across the day

Older muscle responds less strongly to a given amount of protein, a phenomenon usually called anabolic resistance. The practical consequence is that the amount per meal matters more than it does for a young athlete: a total that arrives almost entirely at dinner leaves most of the day without a meaningful signal. Aim for roughly 0.4 g/kg per meal, in the region of 25–35 g, at three or four meals. That is a distribution problem more than a total-intake problem, and it is usually solvable without increasing the food bill much.

Leucine-rich sources make that per-meal threshold easier to reach: dairy, eggs, fish and soya. In an Indian household this typically means curd or milk with breakfast, dal plus rice with an added paneer or curd serving at lunch, and eggs, fish or a soya preparation in the evening. For an older vegetarian, paneer, curd and soya do most of the work, because dal on its own rarely clears the per-meal threshold without a dairy addition alongside it.

5Vitamin D, calcium, and the fall nobody trains for

Vitamin D deficiency is widespread in India despite abundant sunlight, for reasons that are largely practical: indoor working days, covered skin, urban air quality, and darker skin needing longer exposure to make the same amount. Combine low vitamin D with low calcium intake and declining muscle mass and fracture risk rises sharply. A hip fracture threatens an older adult's independence far more than any training variable discussed in this volume. Testing and correction belong with a doctor; high-strength vitamin D should not be self-dosed on the basis of a general recommendation.

Training and nutrition contribute different halves here and neither substitutes for the other. Resistance work and deliberate balance work reduce fall risk directly. Nutrition supplies the calcium — dairy, ragi, sesame, green leafy vegetables — and the protein needed to hold onto muscle mass in the first place. An older client doing balance work on an inadequate protein intake, or eating well while doing nothing that challenges strength, is getting half the available benefit.

6Appetite, teeth and the barriers that actually stop people

The reason an older client misses their protein target is rarely that they disagree with it. Appetite declines with age. Dental problems and poorly fitting dentures make chicken, hard chana and raw salad genuinely difficult. Medications blunt taste or cause nausea. Cooking for one after a bereavement removes most of the motivation to cook at all. A recommendation that ignores these lands as a demand the client cannot meet, and they usually stop reporting honestly rather than argue about it.

The workarounds are mostly textural. Curd, buttermilk, milk, soft paneer, khichdi with added dal and soya granules, well-cooked eggs, soft fish, and dal made thicker rather than thinner all deliver protein without demanding much chewing. Smaller, more frequent servings suit a reduced appetite better than three large meals. And where swallowing difficulty is suspected rather than simple appetite loss, that is a medical assessment rather than a menu problem, and it should be raised with the client's doctor.

• Target 1.8–2.4 g protein/kg daily.
• Train 2–3 days weekly with conservative load progressions.
• Prioritise joint health, vitamin D, and calcium.

Vegetarians

Learning goal: Meet protein and micronutrient needs for muscle building on a vegetarian diet.

Vegetarians (no meat, fish, or poultry, but eggs and dairy allowed) can build muscle effectively with adequate protein and thoughtful food selection. Vegetarian protein sources are slightly less efficient than animal proteins (due to lower amino-acid score and lower digestibility in some plant sources), but when total daily protein and training are adequate, the outcome is the same. The challenge is meeting protein targets affordably and getting adequate iron, zinc, B12, and D-vitamin (if dairy-free or limiting dairy).

1Vegetarian protein sources and combinations

Eggs (complete protein, ~6 g per egg, cheap), milk and yoghurt (complete, ~8 g per cup), paneer (complete, ~7 g per 30 g), dal and legumes (incomplete, ~7–12 g per cooked cup, combine with grain), tofu and soy (complete, ~10–15 g per 100 g), nuts and seeds (incomplete, high fat, ~6 g per ounce). A vegetarian targeting 140 g daily might eat: breakfast (2 eggs, toast, 250 ml milk) = 30 g; lunch (1 cup dal, rice, paneer) = 25 g; snack (100 g yoghurt, nuts) = 15 g; dinner (150 g paneer, roti, lentil curry) = 30 g; total ~100 g from whole foods, +40 g from whey shake = 140 g daily.

2Iron and zinc in vegetarian diet

Plant-based iron (non-heme iron) is less efficiently absorbed than animal-based iron. Combine iron sources with vitamin C (orange juice, tomato, bell pepper) to improve absorption. Red lentils, spinach, beans, and fortified cereals are sources. Zinc is lower in plant sources; combine legumes and seeds (combine pumpkin seeds with dal, for example) to meet needs. A concern: vegetarians may become anaemic if plant iron is not prioritised. Simple blood testing can confirm iron status and guide supplementation if needed.

3Vitamin B12 and vitamin D

B12 is absent from plant sources; vegetarians relying on dairy get B12 from milk and yoghurt, but amounts may be modest. If dairy intake is low or if someone prefers to supplement, a B12 supplement (500–1,000 mcg weekly or 2,000 mcg weekly) ensures adequacy. Vitamin D comes from fortified dairy, egg yolks, and sunlight; if dairy is limited or sun exposure is low, supplementation (1,000–2,000 IU daily) is wise.

4Reaching 1.6 g/kg on a vegetarian plate — a worked day

Take a 65 kg vegetarian athlete with a target near 104 g. Breakfast of 200 ml milk, 150 g curd and two roti gives about 18 g. Lunch of one and a half cups of dal with rice plus a 100 g paneer sabzi adds roughly 30 g. An evening chaat made from 50 g of dry soya chunks contributes around 26 g. Dinner of rajma or chole with roti and curd brings about 28 g. The total lands near 102 g, at somewhere around ₹180–220 for the day.

The single lever doing most of the work in that day is soya, at roughly ₹3 per 10 g of protein — the cheapest protein available in India and near-complete in its amino acid profile. A vegetarian who adds soya somewhere in the day and a dairy serving to each meal rarely has a protein problem worth discussing. A vegetarian relying on dal alone almost always does, because dal is a modest protein source by volume once it has been cooked to the consistency people actually eat it at.

5Absorption: what to pair, and what to keep apart

Iron and zinc from plant sources are less available to the body than the same minerals from meat, largely because of phytates in grains and legumes. The adjustments that help cost nothing. Soak and sprout legumes before cooking. Use fermented preparations — idli, dosa, dhokla — which reduce phytate content. Put a vitamin C source in the same meal rather than later in the day: lemon, tomato, amla, guava or capsicum. Keep tea and coffee an hour away from the iron-containing meals rather than drinking them alongside.

It is worth not over-correcting. The phytate-containing foods are also the foundation of the diet, and they carry fibre, minerals and the bulk of the day's energy; the goal is technique, not avoidance. And where a deficiency is genuinely suspected, testing comes before supplementing. Self-prescribed iron or zinc at high doses can cause harm, and the athlete who assumes a deficiency and treats it blindly usually ends up with neither a diagnosis nor a solution.

• Combine protein sources: eggs, dairy, dal, legumes, soy, nuts, seeds.
• Prioritise iron sources and combine with vitamin C for absorption.
• Supplement B12 if dairy intake is low; ensure adequate vitamin D.

Vegans

Learning goal: Meet protein and micronutrient needs for muscle building on a plant-based diet.

Vegans (no animal products, including dairy, eggs, and honey) can build muscle with careful planning. Plant-based proteins are less efficient individually (lower amino-acid score, lower digestibility), so hitting adequate total protein requires either higher absolute intake or strategic food combining. Micronutrient concerns are more substantial: B12, iron, zinc, vitamin D, and potentially calcium all require planning. A vegan trainee building muscle is feasible but requires more nutritional knowledge than a vegetarian or omnivore.

1Plant-based protein sources and combining

Tofu and soy (complete, ~10–15 g per 100 g), legumes and lentils (incomplete, ~7–12 g per cup cooked, combine with grain), nuts and seeds (incomplete, high fat), whole grains (incomplete, combine with legumes), nutritional yeast (incomplete). Combining sources: rice + beans, hummus (chickpeas) + whole-grain bread, lentil curry + roti, tofu stir-fry with brown rice. A vegan targeting 140 g protein daily might need 160–180 g raw plant protein (accounting for lower digestibility) or rely on soy products. Example: breakfast (100 g tofu scramble, whole-grain toast, seeds) = 25 g; lunch (150 g tofu, lentil dal, rice) = 30 g; snack (peanut butter, banana, almond milk) = 12 g; dinner (200 g tempeh, quinoa, vegetables) = 30 g; whey alternative (pea/rice blend 30 g) = 25 g; total ~120 g.

2Critical micronutrient planning

B12 is absent from all plant foods (unless fortified); vegans must supplement or use fortified foods consistently. Supplement: 500–1,000 mcg weekly or 2,000 mcg weekly. Iron requires combining plant sources with vitamin C and avoiding tannins (tea and coffee) that reduce absorption. Zinc is lower in plants; combine legumes and seeds. Vitamin D must come from fortified plant milk, supplements, or sunlight (1,000–2,000 IU daily is wise). Calcium: fortified plant milk, tofu made with calcium sulfate, seeds, and leafy greens. The micronutrient load is substantial; a vegan trainee should ideally work with a dietitian to ensure adequacy.

3Cost and sustainability

Vegan muscle-building can be cheaper than omnivore (legumes and grains are inexpensive) or more expensive (if relying on specialty plant-based proteins and supplements). The challenge is not cost but complexity: adherence is harder when nutrition requires constant monitoring. A vegan trainee who supplements diligently (B12, vitamin D, omega-3 from algae) and meal-plans carefully (ensuring complete proteins and micronutrient variety) will succeed; one who assumes plants alone are sufficient will struggle with fatigue, anaemia, and poor recovery.

4B12 is the one supplement a vegan genuinely needs

Vitamin B12 is essentially absent from plant foods. Deficiency develops slowly, often over years while stores deplete, and it can cause neurological damage that does not fully reverse. This is a health matter rather than a performance one, and it is the single point in this entire volume where "get it from food" is inadequate advice. A vegan athlete needs a reliable B12 source, with the dose and form confirmed by a doctor and status checked periodically by blood test rather than assumed from the label of whatever they are taking.

Fortified foods are an unreliable route in India specifically, because fortification is inconsistent between products and between batches, so a label needs reading each time rather than trusting a category. Two further nutrients need active planning: vitamin D, and long-chain omega-3 fatty acids, for which algal sources replace fish. Iodine, calcium and iron all warrant attention as well. A vegan athlete who has addressed B12, D and omega-3 has dealt with the genuinely difficult part of the diet.

5Cost-controlled vegan protein in India

A vegan day at 1.6 g/kg costs about the same as a vegetarian one, provided soya carries a reasonable share of it. Soya chunks come in near ₹3 per 10 g of protein, tofu around ₹12–16, and peanuts, chana, rajma, moong and millets fill in the rest at low cost. The protein density of a vegan Indian plate is genuinely lower than a vegetarian one once dairy is removed, which usually means either larger portions or one deliberately protein-dense item per meal rather than hoping the total accumulates.

What actually raises the cost is replacing dairy with branded plant milks and vegan protein powders. Almond milk supplies almost no protein and is frequently bought as though it did; soya milk supplies a useful amount. Fortified soya milk plus soya chunks covers most of what dairy was previously doing, at a fraction of what a specialist vegan protein powder costs. As everywhere else in this volume, the cheap option here is also the effective one.

• Target 160–180 g plant protein daily (higher than omnivore due to lower digestibility).
• Combine sources: legumes + grains, soy products + vegetables.
• Supplement B12 (500–1,000 mcg weekly), vitamin D, omega-3, and monitor iron.

People with Type 2 Diabetes

Learning goal: Use resistance training and nutrition to improve blood glucose control and insulin sensitivity.

People with type 2 diabetes (T2D) benefit substantially from resistance training, which improves insulin sensitivity, reduces blood glucose, and often reduces medication needs. Nutrition principles are largely the same as for non-diabetics (adequate protein, controlled total calories, whole foods over refined), but carbohydrate distribution and timing matter more because rapid blood-glucose changes are harmful. Close medical supervision—ideally with an endocrinologist or registered dietitian—is essential; medication doses often need adjustment as fitness and control improve.

1Resistance training and glucose control

Resistance training directly improves insulin sensitivity: muscles take up glucose without requiring insulin after a workout, and this effect persists for hours to days. A person with T2D training 3 days weekly often sees meaningful reductions in fasting blood glucose and HbA1c (3–month average glucose). Training also preserves muscle mass during weight loss, which is important because diabetes worsens with muscle loss.

2Carbohydrate timing and selection

Rather than avoiding carbohydrates, choose them strategically: whole grains over refined, paired with protein and fibre. Distribute carbohydrate throughout the day (breakfast, lunch, dinner, possibly snack) rather than front-loading or back-loading. Avoid large carbohydrate meals without protein or fibre. A diabetic might eat 130–150 g carbohydrate daily (distributed across meals) instead of 200+ g from refined sources. Blood-glucose monitoring (finger pricks or continuous glucose monitor) after different meals reveals which foods cause spikes; use this data to personalise choices.

3Weight loss and medication adjustment

Weight loss (5–10% of body weight) significantly improves T2D control. As fitness and nutrition improve, blood glucose often improves faster than expected, and medication doses need reduction to avoid hypoglycaemia (low blood glucose). A person taking metformin at 1,000 mg twice daily might need 500 mg once daily after 12 weeks of training and weight loss. This medication adjustment must be supervised by the person's doctor—never stop or reduce medication without medical guidance, and report improving glucose levels immediately so medication can be adjusted.

4Hypoglycaemia around training: recognising it and preventing it

Exercise increases glucose uptake into muscle and can keep blood glucose lower for hours afterwards, including overnight. For an athlete on insulin or on a sulfonylurea, that makes hypoglycaemia a real risk during and after sessions rather than a theoretical one. The symptoms to know are shakiness, sweating out of proportion to the work, confusion, and sudden weakness. Any athlete in this group should train with fast-acting carbohydrate within reach, and should not train alone until their own pattern is understood.

The pattern differs by session type, which is why individual monitoring beats any general rule. Steady aerobic work tends to lower glucose progressively. Short, very intense work can raise it temporarily through the hormonal response, which then falls later. Glucose readings taken before, after and several hours following a session, logged against what was actually trained and eaten, turn this from guesswork into something the athlete and their doctor can manage deliberately.

5Who changes the medication — and who does not

Changes to training and diet change medication requirements. Adjusting an insulin dose or an oral diabetes medication is a medical decision made by the athlete's doctor, and it is not something a coach or a nutrition professional should improvise, however clear the pattern in the logbook looks. What the nutrition professional contributes is exactly that logbook: consistent carbohydrate timing, session records, and glucose patterns around training. That data is what allows the doctor to adjust safely, and it is genuinely valuable to them.

With that division of labour in place, a person with diabetes can train and build muscle like anyone else. Resistance training improves insulin sensitivity, which works in the athlete's favour, and the protein targets from earlier in this volume apply unchanged. The condition changes the monitoring and the communication, not the goal — and framing it that way to a newly diagnosed athlete is often the most useful thing said in the first consultation.

6Carbohydrate quality on an Indian plate

Carbohydrate does not need removing; it needs choosing and portioning. The practical changes on an Indian plate are modest. Reduce the rice portion and raise the dal and vegetable portion in the same meal, which lowers the glycaemic load without removing a food anyone will miss. Prefer whole grains where they are acceptable to the household — jowar, bajra, ragi, hand-pounded or par-boiled rice — and pair rice with dal, curd and vegetables rather than eating it alone.

Two additions do more than most substitutions. Protein and fat in the same meal slow gastric emptying and blunt the glucose rise, so eggs, paneer, curd, dal or nuts alongside a carbohydrate change the response to it. And fibre from vegetables and whole legumes does the same. What deserves limiting rather than balancing is the liquid sugar — sweetened tea taken several times a day, packaged juice, soft drinks — which arrives fast and brings nothing else with it.

• Train 3 days weekly; resistance training improves glucose control more than cardio.
• Distribute carbohydrates throughout the day, paired with protein and fibre.
• Monitor blood glucose; expect medication adjustments as control improves.

Obesity and Muscle Gain

Learning goal: Build muscle while losing fat in someone with obesity.

Someone with obesity (BMI >30) often has years of excess body fat but limited muscle mass relative to body weight. Beginning resistance training and entering a calorie deficit can produce recomposition: loss of fat (2–3 kg per month) alongside small muscle gains (0.5–1.0 kg per month), resulting in a dramatic transformation despite modest scale weight changes. The challenge is not building muscle (which happens easily due to high starting body fat and training stimulus), but maintaining muscle while in deficit and managing the psychological challenges of slow progress on the scale.

1Starting deficit size and protein

A larger starting deficit is feasible: 500–750 kcal below maintenance (vs. 300–500 kcal for leaner people) produces 0.5–1.5 kg fat loss weekly without excessive muscle loss, provided protein is high. Target 2.0–2.4 g/kg protein daily. A 110-kg person at 40% body fat might maintain 2,600 kcal daily (deficit of 500–600 kcal), hitting 200–220 g protein daily. This higher protein, combined with progressive resistance training, preserves muscle during the aggressive deficit.

2Training and exercise tolerance

Joint stress is high in someone carrying excess weight. Prioritise low-impact resistance training (strength machines, dumbbell work, controlled movements) over high-impact cardio early on. As fitness improves and weight decreases, impact tolerance rises. Focus on movement quality and control, not load or intensity. A 110-kg person might start with lighter loads and higher reps (10–15) for motor control, then progress to heavier loads as confidence and strength build. Regular (3–4 days weekly) consistent training is more important than occasional intense efforts.

3Behavioural and psychological support

Someone with obesity losing weight for the first time often faces psychological challenges: years of food patterns, social eating, emotional eating, and shame can sabotage adherence. Professional support—a therapist, registered dietitian, or coaching—is often more valuable than a "perfect" nutrition plan without support. Focus on building one or two sustainable habits (never skip protein, walk 30 minutes daily) rather than trying to be "perfect" immediately. Weight loss is not linear; expect plateaus of 2–4 weeks. These are normal and frustrating but do not indicate failure.

4Can you build muscle in a deficit? When recomposition is realistic

Yes, under specific conditions: an untrained or detrained athlete, higher body fat, adequate protein at roughly 1.6–2.2 g/kg, a moderate rather than aggressive deficit, and consistent resistance training. Larger fat stores supply energy, so the deficit constrains muscle growth less than it would in a lean athlete. Expect strength to rise clearly and size to rise modestly over the first several months. In a lean, trained lifter the same approach largely stops working, and the two goals then need separating into distinct phases.

Practically, this makes the early phase of a heavier beginner's training unusually rewarding: fat falls and strength rises at the same time, which is the outcome almost everyone wants and almost nobody gets twice. It also makes the later phase feel like a stall unless expectations are reset in advance. An athlete told at the start that the simultaneous phase is temporary handles its end far better than one who concludes their programme has broken.

5Joint load, low-impact options, and progressing anyway

Higher body weight increases joint loading in running and jumping, and knee and low-back complaints are common in the first months. Substituting cycling, swimming, incline walking, and machine or supported resistance work keeps the athlete training while tissues adapt to the new demand. This is not a lesser programme; it is the programme that does not get abandoned in week five because something hurts. Continuity beats intensity by a wide margin at this stage, and the plan that gets followed is the one that works.

The scale is also a poor progress measure in this population, for the same reason recomposition is possible: fat and muscle are moving in opposite directions at once. Waist circumference, a fixed set of photographs taken monthly under the same conditions, and load lifted for a given repetition target all give a truer reading. An athlete watching only body weight during a successful recomposition frequently concludes they are failing, and stops.

• Use a larger deficit (500–750 kcal) with high protein (2.0–2.4 g/kg).
• Prioritise low-impact training; progress gradually as fitness improves.
• Seek behavioural/psychological support; habit change matters as much as calorie deficit.

Injury and Rehabilitation

Learning goal: Maintain training and nutrition during injury recovery.

Injury is common in resistance training. A sprained ankle, torn muscle, or shoulder impingement prevents normal training but does not mean stopping all training. Nutrition during injury is critical: reduced training means reduced energy needs, but protein remains high (1.8–2.4 g/kg) to support repair and prevent muscle loss. The psychological challenge is managing reduced activity without guilt, and mental health support is valuable during long injuries.

1Energy and protein during injury

An injured person training 0–1 days weekly needs fewer calories than when training 4–5 days. Reduce intake by 200–400 kcal to match reduced activity, but keep protein high. High protein signals the body to preserve muscle even though training stimulus has decreased. Training uninjured body parts maintains some training stimulus and mental engagement. Modifications: if you have a shoulder injury, train legs and core; if you have a leg injury, train upper body and core carefully.

2Rehabilitation-focused training

Work with a physiotherapist to design rehabilitation exercises that progressively restore function. These exercises may not build muscle but prevent atrophy and restore range of motion. A person with a rotator cuff injury might spend 6 weeks on isometric shoulder work, mobility work, and band exercises before returning to heavy pressing. Patience and adherence to rehab is critical; skipping rehab to return to heavy training faster often causes re-injury.

3Nutritional support for healing

Certain nutrients support tissue repair: protein (as mentioned), vitamin C (wound healing), zinc (immune function and healing), and omega-3s (inflammation management). Meeting these through whole foods is usually sufficient; supplementation is unnecessary unless micronutrient deficiency is confirmed.

4Protein during immobilisation

Immobilised muscle loses mass quickly, and the protein requirement rises rather than falls even though training has stopped. Target the upper end of the range, around 2.0 g/kg, distributed across meals rather than concentrated in one, and lean on leucine-rich sources to make each meal count. Energy should not be cut sharply either: a large deficit accelerates muscle loss and slows healing, and the healing process itself carries a genuine energy cost that is easy to forget when the athlete is visibly doing nothing.

Appetite and mobility are both usually reduced during this period, which makes large meals harder. Small frequent servings work better: curd, paneer, eggs, fish, dal with soya added, and milk before bed. In an Indian household these are all available without a shopping trip, which matters when the athlete cannot easily leave the house. The aim across these weeks is to lose as little as possible, because everything preserved now is time saved in the return.

5Collagen, vitamin C and tendon loading — what is actually supported

There is preliminary evidence that gelatin or collagen taken with vitamin C shortly before a tendon-loading session may support connective-tissue synthesis. Two honest qualifications belong with that. The loading is the essential ingredient and the nutrition is at best supportive, and the evidence base is early rather than settled. Adequate protein and energy overall, along with vitamin C and zinc, matter for healing in a more established way than any single targeted product does.

What is not supported is high-dose anti-inflammatory supplementation intended to speed recovery, which may blunt the adaptive signal the rehabilitation programme is trying to create, or any product claiming to heal a tendon without loading it. Rehabilitation is a loading programme with nutritional support, in that order, and reversing the order is the most common expensive mistake an injured athlete makes.

6Calories when training volume collapses

An athlete who trained six days a week and now trains none has a substantially lower daily expenditure. Holding intake exactly where it was adds fat over a layoff measured in months, which then has to be dealt with during the return. A modest reduction is appropriate — taken from the training-related additions, the extra rice and the post-session foods, rather than from protein or vegetables, both of which are doing work during healing.

The judgement call is timing rather than direction. Reduce too early or too aggressively and healing suffers. Leave intake untouched for three months and the athlete returns heavier, which slows the comeback and raises load on the tissue that just healed. Reviewing intake a couple of weeks in, once the initial healing phase and the swelling have settled, usually gets this balance right.

• Reduce calories by 200–400 kcal to match reduced training, but keep protein high.
• Train uninjured body parts to maintain activity and stimulus.
• Adhere to physiotherapy; patience prevents re-injury.

Return-to-Training After Time Away

Learning goal: Resume training safely and rebuild muscle after extended time away.

Muscle memory allows rapid re-building of muscle after breaks (illness, travel, injury, life circumstances). A person who trained for 5 years, stops for 3 months, and resumes will regain 75% of lost muscle in half the original timeframe. This is due to neural adaptations and satellite-cell memory that persist years after detraining. However, returning too aggressively risks injury and soreness. A conservative return (starting at 60–70% of previous loads, ramping up over 3–4 weeks) prevents injury and burnout.

1Progressive return to training intensity

Week 1–2: 60% of previous loads, higher reps (12–15), daily soreness is expected. Week 3–4: 70–80% of loads, moderate reps (8–12), soreness decreases. Week 5+: return to normal loads and rep ranges. This gradual return re-teaches movement patterns, allows connective tissues to adapt, and prevents overwhelming soreness that kills motivation. Training frequency should ramp similarly: start 2 days weekly, progress to 3, then 4+ over 3–4 weeks.

2Nutrition during return

Protein should match the new training volume (1.6–2.0 g/kg if returning at lower volume). Total calories should support training and recovery without rapid weight gain; expect 0.5–1.0 kg per week as glycogen, water, and muscle return. Creatine supplementation (if used before the break) can speed muscle recovery; starting at loading dose (20 g/day for 5 days) then 3–5 g daily can accelerate the return-to-training effect.

3Mental shift and patience

Returning to training after a long break is psychologically challenging: the strength loss (even temporary) can feel like failure. Reframe it: muscle memory means rapid progress, and a conservative return prevents injury and allows sustained training. The person who returns too aggressively, gets injured, and stops for another 3 months has wasted time; the person who returns conservatively and trains consistently for 12 months makes net progress.

4A four-week ramp, and matching food to rising load

Load returns in stages rather than at once: a first week of technique work and low volume, a second and third rebuilding volume at moderate intensity, and a fourth approaching the intensities the athlete used before. Intake rises alongside it, and carbohydrate is the part that should rise first, since added volume is what consumes it. Protein stays at the elevated rehabilitation level rather than dropping back, because tissue is still being rebuilt through this entire period.

The common error is returning to pre-injury loads because the calendar says the injury has healed. Tissue tolerance is rebuilt by graded exposure, not by time passing, and an athlete who was strong twelve weeks ago is not strong today. The nutrition plan should follow the training actually completed rather than the training that was written down, which in a return phase are frequently different things.

5Re-test rather than guess

Measure instead of assuming. Compare limb girth side to side, test single-leg or single-arm strength rather than only bilateral lifts, record the load managed at a fixed repetition target, and note how the joint feels the following day rather than during the session. These give the athlete something concrete to progress against, and they catch a premature return before it turns into a re-injury — which is the outcome that costs the most time of anything in this chapter.

Body weight deserves reviewing too, and the interpretation cuts both ways. An athlete who gained fat during the layoff is now placing higher relative load on tissue that has just healed. An athlete who lost muscle needs the protein and the energy to rebuild it before load can rise safely. Both are common, and they call for opposite adjustments, so the measurement has to come before the decision.

6Sleep, stress and the pace of the return

A return phase places an unusual load on recovery, because the athlete is rebuilding tissue while relearning movement and often while anxious about re-injury. Sleep does more for that than any nutritional adjustment available, and it is frequently the thing that got worse during the layoff — disrupted by pain, by inactivity, or by lying in bed at odd hours. Restoring a consistent sleep schedule is a legitimate part of the return programme rather than general advice appended to it.

Stress matters for a practical reason as well as a physiological one. An athlete under pressure to be available for a season, a selection or an employer will push the ramp faster than the tissue tolerates, and the nutrition plan cannot compensate for that. Where the deadline is genuinely fixed, say plainly what the trade is: a faster return carries a higher re-injury risk, and that is a decision for the athlete and their medical team to make with the information in front of them.

• Return at 60–70% of previous loads; progress over 3–4 weeks.
• Expect soreness; it is normal and temporary.
• Protein targets match new training volume; expect 0.5–1 kg/week regain.

Chapter Revision

Learning goal: Adapt evidence-based principles to diverse populations and circumstances.

Muscle-building principles (progressive training, adequate protein, energy surplus or deficit matched to goals, sleep) are universal, but how they are implemented differs across populations. A teenager, a woman, an older adult, a vegetarian, someone with diabetes, and someone with obesity all need these fundamentals, but the specifics of execution change. Excellence in coaching and nutrition means personalising these principles to individual constraints, preferences, and health status.

• Beginners: focus on habit-building, not perfection.
• Women: same training and protein as men; account for menstrual cycle if desired.
• Teenagers: higher calories for growth; avoid extreme measures.
• Older adults: higher protein; longer recovery; emphasise function.
• Vegetarians/vegans: strategic food combining; micronutrient planning.
• Diabetes: resistance training improves control; close medical supervision.
• Obesity: large deficit feasible with high protein; behavioural support matters.
• Injury: maintain protein; train around injury; be patient with rehab.

1The chain of reasoning

Every population in this chapter runs through the same sequence. Establish total energy first, because nothing else works underneath an inadequate intake. Set protein next, with attention to the per-meal distribution rather than only the daily total. Identify the micronutrients that this particular population is actually at risk of lacking. Then decide what, if anything, requires a doctor. Supplements come last and for most of these populations barely feature. Working in that order stops the consultation from becoming a product recommendation, which is where most of them otherwise end up.

2Beginners and adolescents

Both groups need simplicity and adequacy rather than precision. Beginners progress fast enough that dietary refinement adds little, so protein at every meal and enough total food carries almost all of the benefit. Adolescents are building tissue before training is added, so their energy needs can exceed an adult's and under-eating shows up as stalled growth and frequent illness before it shows up in the gym. Neither group should be given performance supplements, and neither should be put into a deficit without a clear reason.

3Female athletes

Two issues matter more than anything else specific to female athletes. Iron status, which needs ferritin rather than haemoglobin alone to assess properly, and which is commonly depleted in Indian women. And energy availability, where the key clinical point is that losing periods is never a normal training adaptation and always warrants medical referral. Beyond those, protein targets and training principles are the same as for anyone else, and the frequent claim that heavy training makes women bulky does not survive contact with the evidence.

4Older adults

Anabolic resistance means the per-meal protein dose has to be larger, around 0.4 g/kg or roughly 25–35 g at three or four meals, rather than concentrated at dinner. Leucine-rich sources make that easier, which in Indian practice means dairy, eggs, fish and soya. Vitamin D and calcium status carry unusual weight because fracture risk threatens independence, and vitamin D deficiency is common in India despite the sunlight. Resistance and balance training and adequate protein each do half the job, and neither substitutes for the other.

5Vegetarian and vegan athletes

Vegetarians reach standard protein targets on ordinary Indian food, provided soya or dairy appears at most meals; dal alone rarely does it. Absorption technique — soaking, sprouting, fermenting, adding vitamin C, keeping tea and coffee away from meals — is free and worth applying. Vegans additionally need a reliable B12 source confirmed with a doctor, plus attention to vitamin D and long-chain omega-3 from algal sources. B12 is the one place in this chapter where a supplement is genuinely non-negotiable rather than optional.

6Diabetes and obesity

For an athlete with diabetes, the added requirement is monitoring around sessions and clear communication with the doctor, who owns every medication decision. Hypoglycaemia risk is real for anyone on insulin or a sulfonylurea, and it extends for hours after training. For a heavier athlete, simultaneous fat loss and strength gain is realistic while they are untrained and carrying higher body fat, and joint-friendly training choices keep them training continuously. In both cases the goal is unchanged; the monitoring and the exercise selection change.

7Injury and return

During immobilisation, protein requirements rise rather than fall and energy should not be cut sharply, because muscle loss is fast and healing has a cost. Collagen with vitamin C before tendon loading has preliminary support, while high-dose anti-inflammatory supplementation may work against adaptation. The return itself is a graded ramp over weeks, with carbohydrate rising as volume rises and protein held high. Re-test rather than assume, because tissue tolerance is rebuilt by exposure rather than by the passing of time on a calendar.

Inclusive Special-Population Cases

Learning goal: Apply principles across multiple simultaneous circumstances.

Case A: Female teenager, vegetarian
A 17-year-old girl, 58 kg, vegetarian, begins training. Targets: 1.8 g/kg protein = 104 g daily. Sources: 2 eggs, 250 ml milk, 100 g paneer, 1 cup dal, 100 g yoghurt, 30 g whey. Calories: 2,200 (maintenance + 100 for growth during training). Training: 3 days weekly full-body. Expected: 0.5 kg/month muscle gain + growth/development. Micronutrient focus: iron (dal + citrus), B12 (dairy), calcium (dairy, leafy greens).

Case B: Older adult with type 2 diabetes, beginning training
A 62-year-old man, 92 kg, diabetic, sedentary. Trained 2 days weekly with physiotherapy clearance. Protein: 2.2 g/kg = 200 g. Calories: 2,000 (conservative deficit). Blood glucose monitoring before/after training. Medication review with doctor every 4 weeks as glucose improves. Expected: 0.5 kg muscle gain/month, 0.75 kg fat loss/month, improved glucose control, reduced medication need.

Case C: Vegan returning to training after 6-month injury
A 70-kg vegan returns after shoulder injury, 6 months away. Conservative return: week 1–3 lower loads, training 2 days weekly legs/core. Protein: 180 g daily (higher due to rehab + plant-based), supplemented with pea/rice powder. B12, vitamin D, omega-3 supplements active. Expected: 0.25–0.5 kg muscle regain per week, gradual upper-body rehab integration.

1Case one — Meera, 34, first-time lifter, Pune

Three months into her first structured programme, training three times a week, frustrated by slow progress and asking which protein powder to buy. Her food diary showed tea and two biscuits for breakfast, a rice-heavy lunch, and most of the day's protein arriving at dinner. Total intake was adequate; distribution was not. The recommendation was no powder at all: eggs or curd with paneer at breakfast, and curd added to lunch. Protein went from roughly 45 g to roughly 85 g on the same budget, and progress resumed within six weeks. She was, correctly, told to spend nothing.

2Case two — Ananya, 22, distance runner, Bengaluru

Increasing weekly mileage, deliberately eating less to run lighter, no periods for five months, and two recent stress fractures in the same foot. She had assumed both the missing periods and the fractures were the normal cost of serious training. This was a referral, not a nutrition consultation: she was sent to a doctor with sports medicine experience the same week, with the pattern documented. The nutritional work — raising energy availability and restoring intake around training — ran alongside medical care rather than instead of it. Bone health, not performance, was the priority.

3Case three — Shyam, 16, school wrestler, Rohtak

Brought in by a coach asking which creatine and pre-workout to start him on, and mentioning that the boy usually drops three kilograms in the two days before a weigh-in. Both requests were declined. No performance supplements at 16, and deliberate dehydration for a weigh-in was addressed as a safety matter with the coach and the parents together. What he was given instead was a structured eating pattern around school and training, and a weight-class target he could actually make without cutting. That conversation was the entire intervention, and it was the right one.

4Case four — Mrs Kulkarni, 68, Mumbai

Referred after a fall, doing twice-weekly supervised resistance training, eating a vegetarian diet with almost all her protein at dinner. Breakfast was poha or upma with tea; lunch was dal, rice and a vegetable. Her per-meal protein cleared the threshold once a day out of three. The change was distribution rather than total: curd and milk at breakfast, paneer added to the lunch vegetable, and soya in the evening meal. Her doctor tested vitamin D and calcium separately and managed both. Grip strength and chair-rise time improved measurably over four months.

5Case five — Farhan, 45, type 2 diabetes on medication, Hyderabad

Newly started on resistance training, on oral medication, and experiencing episodes of shakiness and sweating after evening sessions. He had been adjusting his own tablets on the days he trained. The correction was structural: he stopped self-adjusting, began logging glucose before and after sessions along with what he had eaten and trained, and took that record to his doctor, who made the medication changes. Carbohydrate timing around sessions was made consistent rather than variable. The episodes stopped, and his training continued uninterrupted.

• Personalise implementation while keeping principles constant.
• Identify constraints (time, budget, health, preferences) and design around them.
• Seek professional support (dietitian, coach, doctor) when guidance is needed.
