It's long been known that calorie restriction can increase the lifespan of certain animals. More recent studies suggest that intermittent fasting can provide the same health benefits as constant calorie restriction, which may be helpful for those who cannot successfully reduce their everyday calorie intake. “Undernutrition without malnutrition” is the only experimental approach that consistently improves survival in animals with cancer, and extends overall lifespan by about 30 percent. The featured Time article extols the virtues of “non-exercise activity thermogenesis” (e.g., fidgeting), but I believe it is more important to intentionally increase your movement throughout the day. Recent research has shown that prolonged sitting is absolutely devastating to your health, promoting dozens of chronic diseases, including heart disease and type 2 diabetes. Even if you exercise regularly, it will not counteract hours’ worth of sitting. In fact, as explained by Dr. Levine, co-director of the Mayo Clinic and the Arizona State University Obesity Initiative, in the video above: if you’ve been sitting for one hour, you’ve sat too long.
