Introduction

Sleep is one of the most underrated factors in weight loss. Many people focus on diet and exercise but ignore the impact of sleep on hormones, hunger, and metabolism.

How Sleep Affects Weight

Lack of sleep can:

• Increase hunger hormones
• Reduce fullness hormones
• Lead to cravings for unhealthy foods
• Lower energy for exercise

Hormones and Sleep

Ghrelin (Hunger Hormone)

Increases when you don’t get enough sleep.

Leptin (Fullness Hormone)

Decreases with poor sleep.

This imbalance leads to overeating.
