Chopped green bell peppers with a dip, such as unsweetened Greek yogurt, makes an excellent keto-friendly snack. However, it is important to note that half a cup of regular unsweetened Greek yogurt can contain 3–5 g of carbs. It also contains less than 1 g of carbs, which makes it an excellent choice as a keto-friendly snack. The purpose of this restriction is to force the body to use ketones, which are acids formed in the liver, or fat to provide caloric needs. Because it’s best to try keto cycling after your body has already adjusted to ketosis, you likely won’t be able to avoid the challenges of starting keto, such as the keto flu.
