The glycemic index helps explain the dynamics of weight gain and loss very well. Although it is not likely that this is the complete reason in all people why weight is gained in the face of substantial calorie restriction, it would appear to be a primary factor. But before going into what this index is and why it is vital in the management of one’s diet, let’s look first at how fat is formed, and how fat can later be broken down.
