"When dietary carbohydrate intake is restricted, the fastest way to generate glucose intarnally is by degrading protein from amino acid pools, muscle tissue, and, if needed, from essential organs. The breakdown of amino acids occurs when glucose is not plentiful and fat breakdown cannot keep up with energy needs. Thus, carbohydrate can be said to be protein sparing, because when dietary carbohydrate intake is adequate it prevents the breakdown of protein and amino acids. Simply put, the body can't work efficiently without carbohydrate available as the primary source of energy."
"Dietary carbohydrates are converted to glucose which is used for energy production, glycogenfor replenishing carbohydrate stored, and fat given excess energy intake when glycogen stores are full. " Thus, if you are trying to lose fat you should keep your carbohydrate intake around 40% of your intake. Once optimal weight is achieved you should resume the DRI of 60%.

Why is whole wheat or whole grain foods better for you?
"During the processing and refining of a whole grain the bran layter containing fiber and the germ layer containing vitamins, minerals, and fatty acids are removed. This leaves the endosperm for use in refined-grain food products. The endosperm contains starch and protein, which are both needed for baked-food product quality, but it has far less fiber, vitamins, and minerals."
