So you say you’re not hungry in the mornings—a common excuse for many. But it’s best to ignore your stomach’s objections and feed it anyway, says Dr. Jo Lichten, a PhD nutritionist, registered dietitian and the author of "Reboot:How to Power Up Your Energy, Focus and Productivity." “Even if we don't feel hungry after a night’s sleep, our body needs a replenishment of glucose,” says Lichten. “While much of the body can burn fat, which we have plenty of, the brain and red blood cells that transport oxygen throughout our body only burn glucose as its fuel.” What happens if the body doesn’t have glucose to burn? The body will break down muscle and turn it into glucose, which definitely isn’t good, adds Lichten.
