Obesity is no longer viewed simply as a matter of willpower, overeating or lack of exercise. It is now widely understood as a chronic metabolic disease, often linked with diabetes, fatty liver disease, hypertension, sleep apnea, heart disease risk and reduced quality of life. For many people, especially in urban India, weight gain creeps in slowly over years as a result of longer working hours, irregular meals, high-calorie processed food, poor sleep, stress and reduced physical activity, all of which play their own part.

A common example seen in clinical practice is the 38-year-old professional who has tried multiple diets, lost 4–5 kg, regained it, and then stopped trying altogether. Or the middle-aged person with diabetes and fatty liver who is told repeatedly to “lose weight,” but finds that lifestyle modification alone is difficult to sustain beyond a few weeks. This is where modern obesity care is changing. The goal is not to replace diet and exercise, but to give patients a scientifically guided head start, a bridge that helps them lose meaningful weight, experience early improvement, and then use that momentum to build long-term lifestyle change.
