With a low-carb diet, you eat less carbohydrates than recommended. Some low-carb diets aim to improve blood sugar levels. Others are designed to lose weight or are based on the idea that it would be healthier to avoid certain products that contain carbohydrates. There are advantages and disadvantages to a low-carb diet. One advantage is that these diets are usually high in protein, and eating enough protein during weight loss can help maintain muscle mass. A disadvantage is that many low-carb diets tend to provide a lot of saturated fat and very little fiber. A low-carb diet provides 50 to a maximum of grams of carbohydrates per day.
The diabetes and obesity epidemics have stimulated research to assess the benefits and potential risks of low-carbohydrate diets. Some research suggests that low-carbohydrate diets may achieve better early weight loss than comparison diets higher in carbohydrate. Studies of up to 1 year suggest that weight loss on low-carbohydrate diet is comparable with fat-restricted diets with higher carbohydrate content. Limited research has been conducted to evaluate low-carbohydrate diets in managing type 2 diabetes. Although science continues to advance in this field, current research suggests that low-carbohydrate diets can be a viable option for achieving weight loss and may have beneficial effects on glycemic control, triglyceride levels, and high-density lipoprotein cholesterol levels in some patients.

NCBI Bookshelf. Uppaluri 3. Since , and more recently, in , low carbohydrate low-carb diets have been a strategy for weight loss. Today, there continues to be an interest in low-carb approaches. While all low carbohydrate approaches reduce the overall intake of carbohydrates, there is no clear consensus on what defines a low-carb diet. Therefore, studies have defined low carbohydrate as a percent of daily macronutrient intake or total daily carbohydrate load. We will define it here as. Low-carb approaches stem primarily from the hypothesis that lowering insulin, a critical hormone that produces an anabolic, fat-storing state, improves cardiometabolic function, and induces weight loss. One hypothesis of why low-carb approaches produce rapid weight loss compared to other diets is that fats and protein increase satiety and produce less concomitant hypoglycemia. This increase in satiety and less rebound hypoglycemia then reduces hunger and overall food intake and produces a caloric deficit. Additionally, another hypothesis contends that low-carb diets can produce a higher metabolic burn than high-carb diets.
