[ACC Entry] Does Calorie Restriction Slow Aging?

Link: https://slatestarcodex.com/2019/12/12/acc-does-calorie-restriction-slow-aging/   [This is an entry to the 2019 Adversarial Collaboration Contest by the delightfully-pseudonymous Adrian Liberman and Calvin Reese.] About the Authors: Adrian Liberman is currently a PhD student in biology at a university in the mid-Atlantic. He previously worked at the National Institute of Aging and remains actively interested in gerontology and the biological study of aging. Calvin Reese is an author with a BS in Biology. He has always been interested in the possibility of life extension by calorie restriction. Recently, he has reexamined the subject after undertaking a series of intermittent fasts for weight loss reasons. Calvin believes CR extends life; Adrian has long been skeptical. Introduction: Is food making us old? We all agree that food is delicious, and we also all agree that too much food is bad for us, but exactly how bad is it? Various academics have proposed that too much food actually accelerates the aging process, and reducing our food intake via calorie restriction (CR) is one of the most accessible and available methods of extending human life. While billionaires pump vast fortunes into increasingly far-fetched stem cell treatments and consciousness transfers, CR advocates contend that they can get a 10-20% increase in their natural lifespans simply by eating a little less. If true, CR raises a question of enormous significance to gerontology and the science of aging: are our diets aging us one calorie at a time? And if so, can we stop it?
