Intermittent Fasting Protocols for Longevity
Evidence-based fasting strategies including 16:8, OMAD, and extended fasting for autophagy, weight loss, and metabolic health.
Intermittent fasting has emerged as one of the most powerful interventions for metabolic health, longevity, and disease prevention. By cycling between periods of eating and fasting, we activate cellular maintenance programs that would otherwise remain dormant in our constantly-fed modern lifestyle.
The 16:8 protocol - fasting for 16 hours and eating within an 8-hour window - is the most popular approach. It's sustainable long-term and provides substantial benefits including improved insulin sensitivity, enhanced fat oxidation, and increased growth hormone production. Most people skip breakfast and eat between noon and 8 PM.
One Meal A Day (OMAD) involves a single feeding window of 1-2 hours daily. This extended fast of 22-23 hours provides more pronounced autophagy and metabolic benefits but requires adaptation. It's particularly effective for significant weight loss and deep metabolic healing.
Extended fasts of 3-5 days or longer provide the most dramatic cellular regeneration. These longer fasts trigger profound autophagy, immune system regeneration, and stem cell activation. Many longevity-focused individuals do quarterly 3-5 day water fasts for these benefits. Medical supervision is recommended for fasts beyond 3 days.
