Low-carbohydrate diets or low-carb diets are nutritional programs that limit carbohydrate intake. Foods saturated in easily digestible glucose (e.g., glucose, breads, pasta) are limited or substituted with foods made up of a higher ratio of excess fat and moderate necessary protein (e.g., meats, poultry, seafood, shellfish, eggs, cheese, nut products, and seeds) and other food stuffs low in sugars (e.g., most salad fruit and vegetables such as spinach, kale, chard and collards), although other fruit and veggies (especially berries) tend to be allowed. The quantity of carbohydrate allowed varies with different low-carbohydrate diets.
Low carb diets typically stipulate getting significantly less than 40% of calorie consumption from sugars. Some diets limit carbohydrate intake sufficiently to cause ketosis.
