Stress, Cortisol, and Belly Fat

Chronic elevated cortisol drives visceral (belly) fat storage independently of what you eat. The good news: the behavioral fixes are well-studied.

How cortisol drives belly fat

Cortisol shifts fat storage toward the abdomen and increases appetite for high-sugar and high-fat foods.

It also worsens sleep, which raises cortisol further — a spiral that shows up on the scale.

What lowers it

7+ hours of sleep. Daily walking outdoors. Strength training (raises acute cortisol but lowers chronic levels). Cutting caffeine after 2 pm.
