“DON’T GO LOW-CARB! CARBOHYDRATES ENERGIZE your body and brain. So if you cut back on carbs too much, you will feel horrible. Low-carb diets deplete your body of glycogen, the muscle fuel it makes from carb-rich foods. Strange things start happening to your body when it’s deprived of glycogen. Without it, your body makes a less efficient fuel from fat. That fuel is called ketones. Ketones are nasty. They give you bad breath, make you feel dizzy and tired, and make your system slow to a crawl; some research shows they may also cause acid buildup in the bloodstream—which can be lethal. Low-carb eating lowers brain levels of serotonin, a chemical critical to controlling depression and anxiety. So you want to make sure you’re eating enough carbs.”
