But how much protein do you actually need? Can you get enough from everyday foods, and when—if ever—do you need protein powders? From daily protein needs and common myths to supplements and sarcopenia, top doctors answer your biggest questions and explain how much protein is enough for your age, lifestyle and health needs.

Q. How much protein should you eat every day, and how can you tell if you’re getting too little—or too much?

Most healthy adults need 0.8 g/kg/day. Regular exercisers and strength trainers may need 1.2–1.6 g/kg/day, depending on their goals, activity, diet, age and health. Low intake can cause muscle loss, weakness, poor recovery and slower healing. Supplements are usually unnecessary when diet provides enough protein.

“Older adults, people recovering from illness and regular exercisers may need more. The goal is adequate—not maximum—protein,” said Dr Yogesh.

Dr Aijaz said deficiency may initially be silent. Warning signs include muscle weakness or loss, poor recovery, frequent infections, hair loss, fatigue and slow wound healing. Older adults are particularly vulnerable as appetite and food intake may decline with age.

Dr Amit advised older adults, people with poor appetite or restrictive diets, and those recovering from illness to ensure adequate protein intake.

Q. Do you need more protein as you age? How does it help prevent sarcopenia, and why must it be paired with exercise or physiotherapy?

Protein supports muscle, tissue repair, immunity, enzymes and hormones. Healthy older adults generally need 1.0–1.2 g/kg/day, while those who are malnourished or acutely or chronically ill may need 1.2–1.5 g/kg/day. Resistance training may increase needs. Protein provides the building blocks; exercise provides the stimulus.

Dr Supriya said ageing increases the risk of sarcopenia—the loss of muscle mass, strength and function—which can affect walking, climbing stairs, rising from a chair and balance, increasing the risk of falls, frailty and loss of independence. Older muscles also respond less efficiently to protein and exercise.

“Sarcopenia is not inevitable. Inactivity, poor nutrition, illness and prolonged hospitalisation can accelerate muscle loss, while adequate protein and exercise can help preserve strength and function,” she said.

After injury, surgery, hospitalisation or prolonged inactivity, protein and physiotherapy work together: exercise restores strength and mobility, while protein supports muscle repair. Recovery should also consider nutrition, sleep and medical condition. For older adults, the goal is maintaining mobility, balance, independence and daily function.

Q. Do you need more protein if you exercise or strength-train? How much do you need around a workout, and is immediate post-workout protein really necessary?

Dr Yogesh said regular exercise, especially strength training, increases protein needs for muscle repair and adaptation. Resistance trainers generally need 1.2–1.6 g/kg/day; those aiming for substantial muscle gain may need the higher end. However, more protein alone does not guarantee greater muscle gain—it must be paired with resistance exercise.

“Protein does not need to be consumed immediately after exercise,” said Dr Aijaz. Muscle protein synthesis continues for several hours.

The priority is adequate protein throughout the day, reasonably distributed across meals. A protein-rich meal or snack around a workout is convenient, but there is no need to worry about a strict “30-minute anabolic window.”

Q. How should protein intake change for weight loss or muscle building? Are high-protein or keto diets safe for everyone?

Protein needs vary by goal, body composition, activity and health. During weight loss, it helps preserve muscle; for muscle gain, it must be paired with resistance training. More protein does not automatically mean better results—overall diet and calorie balance matter.

High-protein or keto diets may help some people lose weight, but those with kidney/liver disease, metabolic conditions, nutritional deficiencies or certain medications should exercise caution. A balanced, sustainable diet is preferable to restrictive trends.

Dr Amit said protein can preserve muscle and improve satiety during weight loss, while muscle gain requires protein plus resistance training. “Simply increasing protein without appropriate calories and exercise will not build muscle.” High-protein or keto diets are not suitable for everyone; those with kidney/liver disease, metabolic conditions or certain medications should seek medical advice.

Q. How much protein should you have at each meal? Is it better to spread it throughout the day, and does timing matter?

Experts recommend spreading protein across 3–4 meals rather than consuming most of it at dinner.

Edwina recommends 25–40 g per meal, depending on body size and daily needs, including protein at breakfast, when intake is often low. Options include eggs, milk, curd, paneer, tofu, soy, dal, beans, fish and lean meat. A protein-rich snack can fill gaps. Even distribution supports muscle protein synthesis, muscle preservation and satiety.

Dr Sukrit suggests 20–40 g per meal for many active adults, depending on body size and total needs, with protein at breakfast, lunch and dinner. Dr Supriya said the goal is consistency, not counting every gram.

Q. Can you get enough protein from food without supplements? What are the best vegetarian alternatives to paneer, and does cooking affect protein?

Most people can meet their protein needs through food. Whey can help when intake is inadequate or meals are difficult, but supplements should complement—not replace—a balanced diet. Whole foods should remain the main sources, including eggs, dairy, pulses, beans, soy, fish, chicken and lean meat.

“Dal and soy are legitimate protein sources, not ‘impure’ proteins,” said Veena. Soy contains all nine essential amino acids. Vegetarians can rotate moong, masoor, chana, rajma, lentils, soy, curd, milk, tofu, tempeh, nuts and seeds. Combining cereals and legumes, such as dal with rice or roti, supports a balanced amino acid intake. Paneer need not feature in every meal.

Sonal said cooking does not significantly change protein quantity or amino acid composition, and may improve protein digestibility and bioavailability.

Q. Who actually needs protein powder? How should you choose one, are protein bars healthy, and is sattu a good protein source?

Protein powder choice should depend on medical profile, nutritional needs and protein quality. Check protein content, digestibility, bioavailability, added sugar, fat, salt, potassium and other additives. Those with uric acid/creatinine concerns, kidney/liver disease, allergies or other conditions should consult a healthcare professional.

Whey and other powders can help when food alone falls short, but should complement—not replace—a balanced diet. Choose reputable brands and avoid unnecessary additives.

Protein bars are convenient but not always healthy. Some contain sugar, fat and excess calories, while concentrated protein may cause digestive issues. Sonal recommends varied plant and animal protein sources throughout the day.

Sattu is nutritious and affordable, but not equivalent to protein powder. Made from roasted gram or pulses, it provides protein, fibre, complex carbohydrates and minerals. It can be used at breakfast or as a snack, but larger quantities may be needed to match a supplement’s protein.

Veena advised checking sattu for added sugar, salt and additives and seeking advice with kidney or digestive disorders. Dr Aijaz noted that its protein content varies with preparation and quantity, so its adequacy depends on overall daily intake.

Q. Is protein powder safe for older adults? Who should limit or avoid supplements?

Protein powder can be safe for older adults when needed and medically appropriate. Combined with strength training, it can help counter age-related muscle loss. Those with kidney/liver disease, dysphagia, multiple illnesses or medications should consult a doctor first. Supplements should complement meals, not replace them, and should contain minimal unnecessary ingredients.

“It can help older adults with poor appetite or muscle loss, but should not be routine. Consider kidney function, illnesses, medications, diet and nutritional status. Protein may help with frailty and sarcopenia, but supplementation must be individualised,” said Dr Aijaz.

Q. Can too much protein harm your kidneys, liver or digestion? Does it raise diabetes risk, and how can you prevent constipation?

Protein needs should be individualised, particularly for older adults with sarcopenia, kidney disease, diabetes, illness or malnutrition.

Protein itself does not cause diabetes; amount, source and overall diet matter. Very high animal-protein intake has been associated with diabetes risk in some observational studies, while plant protein may be more favourable. Prioritise pulses, soy, dairy, nuts and seeds over excessive intake.

“For healthy people, higher protein within reasonable limits is generally safe. Very high intake can cause bloating, constipation, diarrhoea or dehydration. Those with kidney or liver disease should seek medical advice before increasing protein,” said Dr Sukrit.

Dr Amit said risk depends on protein source and overall diet, with frequent processed or red meat intake more concerning than protein alone. Balance protein with vegetables, fruits, whole grains and healthy fats.

To prevent constipation, ensure protein does not displace fibre and fluids. Include water, fruits, vegetables, whole grains, legumes, nuts and seeds, increase protein and fibre gradually, and avoid excessive reliance on processed protein foods or supplements.

Q. What is the biggest protein myth, and what one simple change can improve your protein intake?

The biggest misconception is that protein is only for gym-goers. It is a basic nutritional requirement for everyone.

“Those who exercise, especially with resistance training, may need more for muscle recovery and adaptation. Simply put, protein provides the building blocks; exercise provides the stimulus,” said Dr Supriya. The simplest change: include a protein source in every major meal rather than consuming most of it in one meal.
