Too many carbs turn into sugar, and sugar turns into fat. Too little, and we can slower our metabolism to a crawl and land on a plateau where we aren't able to go anywhere. Again, we have to have balance. They also regulate how our body uses the carbohydrates we take in. Proper protein comes from tofu, chicken, turkey, fish, eggs, lean red meat, and soy products.
Good fats help to burn bad fats in our body.
Fats can also help lower insulin production, as well as providing energy, assisting our body with proper use of vitamins, helping our digestion, maintaining our immune system and much more. Good fats can come from olives, olive oil, avocados, clear salad dressings, almonds, macadamia nuts and pistachios. Of course we also need a proper diet of the four food groups. These things are not hard to keep track of. You need lots of water and at least a little exercise every day.
