Why It Works (The Science)
- Insulin SensitivityWhen you don't eat, insulin drops. This signals your body to access stored body fat for energy.
- AutophagyCellular cleaning. Your body eats old, damaged cells and proteins, reducing cancer risk and aging.
- Growth HormoneHGH levels can increase 5x during fasting, which helps preserve muscle and burn fat.
- Caloric DeficitBy skipping a meal, you naturally remove 20-30% of your daily calories without counting.
