Hi, I'm Teresa Howes, and welcome to My Fresh Kitchen. Today, I want to tell you what happens when carbohydrates get too low. Carbohydrates are your body's primary source of fuel, and you get them from things like fresh fruits, vegetables, whole grains and even sugar. Your body will always burn its carbohydrates. Once you eat them, it will break them down for immediate energy, or it will store them in your liver for glycogen for later on, or it will store them as fat. If you don't enough carbohydrates, your body will use all of its glycogen stores, and everything will run just fine, until they run out. When your body's depleted of glycogen, you'll probably lose about five pounds, because glycogen holds a lot of water, and then your body has to do a little bit more work to make energy. So it goes into secondary fuel sources, which would be fats and proteins for a process called ketosis. The byproduct of ketosis is ketones in your blood, and that results in dry mouth, headache, bad breath and actually decreased appetite. And that's why you'll find out that a lot of these low carbohydrate diets result in so much weight loss. It's because of the glycogen loss, and also the decrease in appetite. If you're not as hungry, you don't eat as much. Low carbohydrate diets are about a thousand calories a day, and that is really tough to get in all the nutrition that you need in a day. So your best line of defense is to follow a healthy diet, and follow the healthy guidelines of making sure you get at least 45 percent of your calories from carbohydrates, and not more than 65 percent to maintain really healthy energy levels.
