A keto diet is where you are permitted to eat a very small amount of carbohydrates. The quality of food does not matter in a Keto Diet. A keto diet is designed to obtain more calories from fat and protein and a minimum amount from carbohydrates. People are advised to cut back on common carbs such as sugar, pastries, soda, and white bread. Though Allulose is a carbohydrate, it does not spike the blood glucose level as it is hardly digested and thus is keto-friendly.
