  low-carbohydrate | Low-carbs dietLow-carbohydrate , Low-carbs diet Low-carbs diet often differ in the specific amount of carbohydrates allowed, whether certain types of foods are preferred, whether occasional exceptions are allowed, etc. Generally they all agree that processed sugar should be eliminated, or at the very least greatly reduced, and similarly generally discourage heavily processed grains (white bread, etc.). Low-carbs diet vary greatly in their recommendations as to the amount of fat allowed in the diet although the most popular versions today (including Atkins) generally recommend at most a moderate fat intake. Although Low-carbs diet are most commonly discussed as a Low-carb weight-loss approach some experts have proposed using low-carbohydrate diets to mitigate or prevent diseases ranging from diabetes to cancer to epilepsy. Indeed, it has been argued by some low-carbohydrate proponents and others that it is the rise in carbohydrate consumption, especially refined carbohydrates that have caused the epidemic levels of many diseases in modern society. As a related note, there is a set of diets known as low-glycemic-index diets (low-GI diets) or low-glycemic-load diets (low-GL diets), in particular the Low GI Diet by Brand-Miller et al. In reality, low-carbohydrate diets are, literally speaking, low-GL diets (and vice versa) in that they specifically limit what contributes to the glycemic load in foods. In practice, though, "low-GI"/"low-GL" diets differ from Low-carb weight-loss in the following ways. First, low-carbohydrate diets treat all nutritive carbohydrates as having the same effect on metabolism and generally assume that their effect is independent of other nutrients in food. Low-GI/low-GL diets base their recommendations on the actual measured metabolic (glycemic) effects of the foods eaten. Second, as a practical matter, low-GI/low-GL diets generally do not recommend diets with glycemic loads low enough to minimize insulin production and induce ketosis, whereas low-carbohydrate diets generally do. Another related low-carbohydrate type, the low-insulin-index diet, is very similar except that it is based on measurements of direct insulemic responses (i.e. the amount of insulin in the bloodstream) to food rather than glycemic response (the amount of glucose in the bloodstream). Although the diet recommendations mostly involve lowering nutritive carbohydrates, there are some low-carbohydrate foods that are discouraged as well (e.g. beef). At the heart of the debate about most low-carbohydrate are fundamental questions about what a normal diet is and how the human body is supposed to operate. Although originally low-carb forum were created based on anecdotal evidence of their effectiveness, today there is a much greater theoretical basis on which these diets rest. The key scientific principle which forms the basis for these diets is the relationship between consumption of carbohydrates and their effects on blood sugar (i.e. blood glucose) and hormone production. Blood sugar levels in the human body must be maintained in a fairly narrow range to maintain health. These questions can be summarized as follows. Nutritive carbohydrates (starches and sugars) in the diet tend to break down very easily into glucose in the bloodstream (blood sugar) when consumed. Glucose in the blood is used by the cells in the body for energy for their basic function.
