Friend eats all day and stays skinny, but you gain weight after one bite? Harvard-trained gut doctor explains why

Harvard trained gut specialist Dr Saurabh Sethi explains why some people gain weight despite eating very little while others stay slim even with larger meals. In his Instagram report, he says the key difference lies in Basal Metabolic Rate, muscle mass, hormone balance and lifestyle factors like sleep, stress and daily movement. He emphasises that weight gain is often physiological, not a lack of willpower, and recommends building muscle and improving metabolic health rather than extreme dieting.
