The problem , however , is that when blood sugar spikes and insulin is secreted , blood sugar is normalized in a matter of minutes , while insulin remains “ on guard ” in the bloodstream for the next couple of hours — preventing fat to be burned during that time .
Understand that various cells in the body have a need for fat . However , when those cells that need fat to function properly are not getting the fat they need ( because of insulin present in the bloodstream ), your blood sugar drops . Low blood sugar level is what tells your brain that you ’ re hungry … and because you are hungry , you begin to eat again before those fatty acids can ever be burned up . When you follow up with another carbohydrate-rich meal , those fatty acids will need to be stored away because your body is going to have to secrete insulin to lower blood sugar again … and to use that blood sugar — instead of fat — for its energy for the next few hours . And this starts the vicious cycle all over again — constantly prohibiting your body from burning fat .
