Definition: Ketosis refers to a process in which the body converts fat into energy, leaving ketones, a by product of this process. Ketosis may happen when following a low carb diet, after fasting or even after very long periods of exercise. While there are people who believe that ketosis can be harmful, Low Carb Diet Guide Laura Dolson states that, while people assume that burning more fat for energy prevents the body from getting enough glucose, "...there is no indication, from studying people on reduced carbohydrate diets, that this is the case."
