Intermittent Fasting and Longevity

Definition

Practice of abstaining from food for a defined period to benefit from regenerative and protective effects on longevity.

How it works

Intermittent or prolonged fasting activates powerful biological mechanisms including autophagy, mitophagy, and improved metabolic sensitivity. During fasting, the body shifts from glucose metabolism to fatty acid metabolism, producing beneficial ketone bodies for the brain. This metabolic transition also stimulates the production of nerve growth factors and reduces chronic inflammation. Studies suggest that regular fasting may increase lifespan and improve metabolic and cardiovascular health markers.

Role

Trigger autophagy and cellular regeneration to strengthen immunity and slow aging.

Examples

• Intermittent fasting 16:8 (16 hours fasting, 8 hours eating window)
• 24 hours fasting once a week
• Alternate fasting (one day on, one day off)
• Prolonged fasting of 3-7 days under medical supervision

Recommendations

Start with short intermittent fasting (12-14 hours) before increasing the duration. Stay hydrated with water, unsweetened tea, or coffee. Consult a professional before fasting if you have medical conditions or take medications.

Key takeaway

Regularly practiced intermittent fasting can activate essential cellular regeneration mechanisms for a longer and healthier life.
