A carbohydrate diet is a type of eating plan that focuses on consuming foods high in carbohydrates while limiting or avoiding other types of food. Carbohydrates are one of the three main macronutrients, along with proteins and fats, and they provide energy to the body. In a typical carb-focused diet, individuals may consume large amounts of grains, fruits, vegetables, legumes, and other foods that contain high levels of carbohydrates while reducing or eliminating consumption of animal products, dairy, and other low-carb foods. The goal of such a diet is often to achieve weight loss, improve athletic performance, or manage blood sugar levels in individuals with diabetes.
