Energy balance

Calorie restriction (CR) extends lifespan in many organisms, and this effect is mediated by Sirtuins, although the requirement for Sirtuins varies by species, strain, and CR protocol.

Consider modest calorie restriction or time-restricted eating as a strategy to potentially activate Sirtuin pathways. Focus on nutrient-dense foods. Be aware that individual responses vary, and extreme restriction is unnecessary and potentially harmful.

Why this rating

Consistent lifespan extension in CR, but Sirtuin dependency is debated.
