Weight Loss and No-Carb Diet - as part of the expert series by GeoBeats. Hi, I am Heather Rudalavage with Intuitive Nutrition. I am a registered dietician, and I help people improve their energy and health by eating better every day. Well following a low-carb diet would actually cause you to lose weight, you would likely re-gain any weight that you lost once you resume a normal diet, and that is what called yo-yo dieting. A low-carb diet is known as a crash diet because it does force you to lose weight mostly because it is low in calories, but also because it forces your body to burn muscle for fuel. As your body goes to muscle to burn fuel, the muscle breaks down and releases water. So a lot of the weight you lose is actually muscle and water weight.
