A common source of sugar in a typical American diet is sweetened beverages including sodas, sweetened teas, sports drinks, and juice. These drinks are not advised on the keto diet because they add carbohydrate without providing any valuable nutrients. Zero-calorie sweeteners are also not recommended because they can increase your cravings for sweets.
