It is not limited to gym, sports and fitness enthusiasts anymore, as we see India's protein craze spreading all over. It's making its way into homes, into supermarket shelves, into hospitals' nutritional programs and into corporate investment plans. There's a significant scientific reason why this change is happening—the fact that protein does more than build muscles. It can affect the hormones that regulate appetite, may help to keep you feeling full after eating and may aid in maintaining weight loss. But the bigger question for India is whether this awareness of nutrition will have an impact on health or simply another lucrative consumer market?

In recent times, protein has gained a new reputation for its hunger-regulating properties. ISIC Multispeciality Hospital's Dr Vijay Dutta has shared that the intake of protein affects hormones that regulate appetite (food intake) like ghrelin, which triggers hunger. Eating a meal with protein can also make people feel full longer than a meal that is high in rapidly digested carbohydrates, which may help them to avoid too many calories and snacking.

The scientific aspect is far more interesting than the well-known “eat more eggs/paneer/protein supplements”. Protein is broken down into amino acids in the digestive system, which triggers a few biological responses including in the stomach, intestines and brain. Hormones like glucagon-like peptide-1 (also known as GLP-1) and cholecystokinin (CCK) can transmit fullness signals, while ghrelin may be reduced. These mechanisms account for some of the reported variations in hunger experiences after a similar calorie intake from different foods.

The 49 publications on short-term protein interventions and 19 on long-term consumption were the subject of a systematic review and meta-analysis published in Physiology & Behavior. Scientists discovered that protein boosted the feelings of fullness and lowered hunger immediately after the meal. They also noticed a change in ghrelin, cholecystokinin and GLP-1. But the longer-term evidence for appetite suppression was not conclusive. This is important, since a sense of fullness can lead to short-term weight loss, which is not necessarily a long-term outcome.

The message is straight-forward for India's growing obesity and diabetes problem. Rice, wheat and other cereal based foods are common in Indian diets, and protein intake is different between different income groups, regions and preference groups. Traditional foods like pulses, chickpeas, milk, curd, soya beans and paneer provide practical sources of protein, but it is the quantity, how it is prepared, and context in which it is consumed, that make the difference in their nutritional contribution.

The recommended dietry allowances (RDA) for healthy adults given by ICMR is around 0.83 grams of protein for each kg of body weight per day. This comes to about 58 grams for an adult that weighs 70 kilograms. The needs can change as people age, as they become more active or if they become ill or participate in supervised weight-loss programmes. But people with some kidney disease will need to have their protein level carefully monitored instead of a liberal amount.

With the global spread of obesity drugs, this nutritional controversy has gained new relevance. The impact of drugs that act on GLP-1 pathways on weight management treatment has been a game-changer, providing significant commercial potential for pharmaceutical companies. However, along with suppressing appetite, some medications may also affect the amount of food eaten, which can cause protein deficiency, vitamin and mineral deficiencies, and muscle loss.

A September 2026 Asian Indian expert consensus on nutrition during GLP-based therapy highlighted ensuring quality and sufficient protein intake, nutrition counselling and maintaining lean muscle mass. Its recommendations are indicative of a new medical fact: there is no single scale that can determine the success of weight management. Theriogenic fitness, metabolic fitness and nutritional fitness are all important.

The commercial potential is huge for the Indian food industry. There is competition for consumers in terms of protein fortified dairy products, nutritional drinks, packaged snacks and specialty foods. Protein processing is a major investment worldwide by major dairy and ingredient companies, especially whey which was once considered to be a by-product in cheesemaking. Increased demand for these ingredients has been bolstered by the rise in weight-loss treatments and consumer preference for such products.

Yet, an increase in demand is not a guarantee for nutrition improvement. A high-protein product that is packaged and advertised as such might also have a high amount of sugar, sodium, saturated fat or unnecessary additives. Those who purchase premium food for their higher nutritional claims may not be getting what they're paying for. Hence, pressure is mounting on regulators and manufacturers to make protein claims meaningful and backed up with clear labelling.

A more basic economic problem that India is grappling with is its affordability. Expensive supplements are no substitute for a dietary transition program for millions of households that produce food inequality. Affordable pulses, dairy and soy products and locally available foods are still important. There is a greater potential to benefit from investments in agricultural productivity and food processing, as well as in cold-chain infrastructure and nutrition education than from the marketing of more and more protein-enriched products.

The importance of nutrition and economic productivity needs to be explored more. Low food quality can lead to poor health, diminished physical function, and increased health care costs. Improved nutrition, along with physical activity and preventive health care, can boost participation in the workforce and may lessen the long-term impact of metabolic disease.

Protein, however, shouldn't be another food fad. A nutritious diet with sufficient protein, vegetables, fibre rich carbohydrates and healthy fats are more helpful than using powders and fortified snacks in place of normal foods. A high protein diet is not necessarily healthy and the elderly or those with medical problems may need professional advice.
