Question

Quizplus · Accepted Answer

Studies on caloric restriction in animals have shown an increase in lifespan, but the exact translation to humans is uncertain. However, estimates suggest that persistent energy intake restriction of 30% over 30 years might extend human lifespan by up to 3 years, though this is based on extrapolation from animal studies and the exact benefit in humans remains to be fully determined.
