14 Hours Fasting

• Insulin levels start to drop, promoting fat burning.
• The body begins shifting to using fat for energy.
• Growth hormone levels start increasing, aiding in muscle preservation and fat metabolism.

16 Hours Fasting

• Ketosis begins: The body starts breaking down fat for fuel instead of glucose.
• Increased autophagy: The body clears out damaged cells and proteins.
• Improved insulin sensitivity continues.
• Hunger hormones may rise temporarily but stabilize with adaptation.

24 Hours Fasting

• Deeper autophagy: Cellular repair mechanisms are more active.
• Significant reduction in insulin and blood sugar levels.
• Increased ketone production for brain and energy metabolism.
• Growth hormone levels are significantly elevated (up to 5x).

36 Hours Fasting

• Full ketosis: The body is primarily using fat and ketones for energy.
• Enhanced autophagy: Damaged cells and proteins are recycled.
• Reduced inflammation and oxidative stress.
• Improved gut health as the digestive system resets.
• Blood sugar and insulin levels remain very low.

100 Hours Fasting

• Maximum autophagy: Supports deep cellular repair.
• Stem cell regeneration: New immune and intestinal cells are produced.
• Deep ketosis: Fat burning is highly efficient, and brain function benefits from ketones.
• Drastic insulin and glucose reduction.
• Risk of electrolyte imbalance increases (sodium, potassium, magnesium).
• Possible muscle breakdown if protein intake was low before fasting.

Refeeding Considerations

1. After 36+ hours of fasting, refeeding should be done gradually.
2. Avoid overeating immediately to prevent digestive distress.
3. Start with light, nutrient-dense foods like bone broth or cooked vegetables.
4. Ensure proper electrolyte replenishment (sodium, potassium, magnesium).
