The 35–50 window is where metabolism quietly shifts. Knowing what's happening helps you act.
What changes
Muscle mass starts declining 0.5–1% per year. Resting metabolic rate drops. Insulin sensitivity falls. Same diet that worked at 25 now adds weight.
Why Indian men are more vulnerable
Higher baseline insulin resistance, lower muscle mass, earlier onset of metabolic disease. The 'comfortable extra 5 kg' is rarely just cosmetic — it usually means rising HbA1c.
What helps
Resistance training (preserves muscle), protein intake (rebuilds muscle), GLP-1 when lifestyle alone isn't enough.
