Belly fat 101: nutritionist links refined carbs and stress to insulin resistance

Nutritionist Dr Rohini Patil explains belly fat isn’t just about overeating; refined carbs and sugary foods cause blood sugar swings that raise insulin and can drive insulin resistance and belly fat. Not eating enough protein or fiber, irregular eating, stress and sleep deprivation, and ultra-processed foods with trans fats and added sugars also fuel inflammation and insulin resistance. A sustainable approach—balanced meals with protein and fiber, regular meal times, exercise, adequate sleep, and stress management—improves insulin sensitivity and supports long‑term metabolic health.
