A very low-carb or no-carb diet can be helpful for losing weight. However, usually the way you accomplish this is to eat lots of meat and fatty foods, which usually will increase your cholesterol and increase your risk of diabetes and several cancers. Also, most people find it very difficult to stick to a very low-carb diet, and they often end up gaining back all the weight they lost.
