Caloric restriction in humans reveals immunometabolic regulators of health span
IANAE, can only talk from personal experience and observing the people around me. Having started practicing intermittent fasting recently, one of the most interesting aspects of the experience is to see how my body's needs change according to my level of physical activity. On days when I'm not physically active, it's quite astonishing how little fuel my body needs.<p>We're all (in developed countries at least) raised on having three meals a day, day in day out, without much consideration for whether our body needs it.<p>In fact, we're conditioned to feel hungry three times a day, regardless of whether we really need to eat. I've also noticed how many people (myself included) would eat compulsively, or out of sheer boredom.
