Energy balance
Caloric restriction and time-restricted feeding can extend healthspan and lifespan in animal models and improve metabolic health in humans, sometimes without weight loss, by reshaping molecular pathways in adipose tissue and aligning with circadian rhythms.
Try time-restricted feeding or caloric restriction without focusing solely on weight loss. Align your eating window with your circadian rhythm (e.g., eat earlier in the day) to maximize metabolic benefits and potentially extend healthspan, even if your weight doesn't change.
GoodSupportsHIGH confidence
Daily calorie restriction without malnutrition reduces body weight, enhances health, and extends lifespan... molecular pathways linked to weight loss and longevity are reshaped in human adipose tissue in response to caloric restriction... favorable effects on health and survival have been found for energy restriction–based interventions in the absence of body weight loss

- Obesity accelerates aging and increases mortality risk in younger individuals, but the relationship between adiposity and mortality becomes non-linear and potentially protective in elderly populations, where overweight status may be associated with lower mortality than healthy weight.Good
- Visceral adipose tissue (VAT) is a stronger predictor of mortality risk than overall BMI or subcutaneous adipose tissue (SAT), while SAT may be associated with lower mortality risk.Good
- GLP-1 receptor agonists (GLP-1 RAs) show promise as gerotherapeutic drugs by protecting against aging-related risk factors such as oxidative stress, cellular senescence, and inflammation, and may reverse brain aging and prevent sarcopenic obesity, although lifespan extension in humans is not yet reported.Moderate
