A balance is needed so that you sufficiently restore the glycemic stores thereby providing the energy you need, but not overdoing it. If you add too much ready fuel ready fuel, the body has to do something with this excess. This is why the high and moderate glycemic carbs are best taken in before the evening meals. The low glycemic foods can be used later in the day, although you can use these at other times. Protein builds and repairs muscles, ligaments, tendons and other body tissues.
Protein synthesizes enzymes, hormones and antibodies.
Protein is not a basic energy source. If you are not taking in enough calories and carbohydrates to take care of your energy needs, protein will be called upon to supply the extra energy the body needs. The body uses some of the protein for fuel. Protein will therefore not be available for the primary job it was intended for. It seems like you are going to be leaving a deficit that cannot be filled by normal means.
