How does sleep affect weight loss?

Too little sleep raises the hunger hormone ghrelin and lowers satiety hormone leptin, increasing appetite and cravings the next day.

How much sleep do I need for weight loss?

Most adults need 7–9 hours. Consistently under ~6 hours is linked to stronger cravings and slower fat loss.

Why am I hungrier when I sleep badly?

Poor sleep and stress shift hunger hormones and raise cortisol, which drives cravings for high-carb, sugary foods.
