Calorie restriction without malnutrition involves reducing overall energy intake while ensuring all essential nutrients are consumed. This activates cellular pathways such as mTOR, AMPK, and sirtuins, which are crucial for cellular repair, stress resistance, and metabolic efficiency. It is a fundamental strategy shown to extend lifespan and healthspan in diverse organisms by improving metabolic health, reducing inflammation, and enhancing cellular resilience.
Verdict
Potent healthspan intervention, requires careful planning and nutrient monitoring.

Protocol
- A common approach involves reducing daily caloric intake by 15-40% below typical maintenance levels.
- Ensuring micronutrient sufficiency through nutrient-dense food choices and potentially supplementation is critical.
- This practice often involves careful dietary planning to avoid deficiencies and maintain lean muscle mass.
Flags
- Risk of nutrient deficiencies if not carefully planned or monitored.
- Potential for loss of lean muscle mass, especially without adequate protein intake and exercise.
- Common side effects include feeling cold, reduced libido, and potential impacts on mood.
- Requires significant discipline and careful monitoring, ideally with medical supervision initially.
