How to Actually Lose Belly Fat (Evidence-Based)

Belly fat responds to a total-body calorie deficit, not crunches. But the good news: visceral fat around the organs is the first fat you lose when you start.

What the studies show

A modest calorie deficit (300–500 kcal/day) combined with strength training preserves lean mass and preferentially reduces visceral fat.

High-protein diets (0.7–1.0 g per lb of goal weight) protect muscle during the cut and blunt hunger.

Sleep matters: under 6 hours a night raises cortisol and blunts fat loss even in a deficit.

Track waist, not just scale

Weight can plateau while your waist keeps shrinking — that's recomposition. Measure your waist weekly for a truer picture.

Check your waist-to-height ratio to see if it's working.
