Low-carb diets reduce glucose and insulin levels, potentially activating nutrient-sensing pathways like AMPK and inhibiting mTOR, mimicking aspects of caloric restriction. This metabolic shift may improve metabolic flexibility, reduce inflammation, and support cellular repair mechanisms relevant to longevity.
Verdict
Effective for metabolic health; plan carefully for long-term safety.

Protocol
- Typically involves restricting carbohydrate intake to less than 50-100 grams per day, often aiming for nutritional ketosis.
- Focuses on whole, unprocessed foods, healthy fats, and adequate protein while minimizing refined sugars and grains.
Flags
- Potential for nutrient deficiencies if not well-planned.
- May cause 'keto flu' symptoms initially (fatigue, headache).
- Not suitable for individuals with certain medical conditions without medical supervision.
- Long-term effects on bone density and cardiovascular health require ongoing research.
