Dietary restriction (DR) and intermittent fasting (IF) extend lifespan and improve health markers in animal models and humans, with some evidence suggesting greater longevity benefits in females, though IF may be more feasible for women.

Dietary restriction and intermittent fasting can improve health and potentially extend lifespan, with some animal studies showing greater benefits for females. For women, intermittent fasting (e.g., eating normally on 5 days and restricting calories on 2 non-consecutive days) is a feasible way to reduce weight and improve insulin sensitivity without the extreme deprivation of continuous DR. Consult a healthcare provider before starting, especially if you have underlying health conditions.
