However, it also drives your body to use more carbohydrate, and less fat, as fuel. And, insulin converts almost half of your dietary carbohydrate to fat for storage. If you want to use more fats for energy, the insulin response must be moderated. Diets high in refined sugars release more insulin thereby allowing less stored fat to be burned. Glucagon promotes the burning of fat and sugar.
Growth hormone is used for muscle development and building new muscle mass.
Insulin also causes hunger. As blood sugar increases following a carbohydrate meal, insulin rises with the eventual result of lower blood sugar. Cravings, usually for sweets, are frequently part of this cycle, leading you to resort to snacking, often on more carbohydrates. If the problem is chronic, you never get rid of that extra stored fat, and your energy is adversely affected. Insulin responses can vary greatly from person to person.
