Why is sleep so important to losing weight?
Here a few reasons:
1. Sleep promotes leptin and leptin is your satiation hormones. Being more satiated will help you eat less.
2. Sleep lowers ghrelin and ghrelin is your hunger hormone. Feeling less hungry will definitely make eating at a calorie deficit easier.
3. Sleep lowers cortisol and cortisol causes appetite increase which can make you eat more. Having less cortisol also reduces the chances of muscle catabolism (muscle burns more fat at rest).
4. Sleep can promote healthy thyroid and thyroid is your metabolic hormone.
