The post examines whether calorie restriction slows aging, concluding it likely does but may not be worth the drawbacks for most people. Longer summary

This post discusses the effects of calorie restriction (CR) on aging and longevity, examining evidence from animal studies, human population studies, and proposed biological mechanisms. The authors review the paradox between lab animal studies showing increased lifespan with CR and human population studies suggesting optimal longevity at normal BMIs. They conclude that while CR likely extends lifespan modestly, the potential risks and discomfort may outweigh the benefits for most people. Shorter summary
