How to Lower Your BMI Safely

Lowering BMI is really about lowering fat mass while protecting muscle. Aim for 0.5–1% of body weight per week — faster loss usually means muscle and water, not fat.

The three levers that move BMI

A small, steady calorie deficit (300–500 kcal/day).

Protein at 1.6–2.2 g/kg to preserve muscle while losing weight.

Strength training 2–3× per week so the weight you keep is lean tissue.

What to track instead of daily BMI

Weekly average weight, waist circumference, and how clothes fit. BMI moves slowly; these signals move first.
