New research reveals that sleep quality directly impacts weight management through hormonal regulation, metabolism, and eating behaviors. Poor sleep may sabotage even the best diet and exercise plans.
The Hormonal Impact
Sleep deprivation affects two key hormones:
- Ghrelin: Increases by 15% (hunger hormone)

After just 4 days of poor sleep:
| Effect | Impact |

| Fat Storage | ↑ 55% |
| Calorie Burn | ↓ 5-20% |
