Frequently Asked Questions
- 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.
