Basically, your body feeds on energy that comes primarily from glucose, which is stored in the body as glycogen. The idea behind the keto diet is that if you reduce carbohydrates, your body depletes its glycogen reserves, so you have no choice but to burn fat, which in turn leads to weight loss. "When you consume a lot of carbohydrates and your glycogen stores are full, the speed at which you get drunk usually slows down," says Dr. Josh Ax, DNM, CNS, DC, founder of Ancient Nutrition and DrAxe.com. "This is because there are more substances in the blood and in the body that are able to absorb alcohol." In fact, some studies have found that eating foods that are high in carbohydrates reduces the amount of alcohol in the blood up to 2 hours after drinking.
