A glucose disposal agent like RPG transfers glucose from the bloodstream into the muscle cell, where it is stored as glycogen, so lowering blood glucose levels. Your body uses glycogen as fuel for anaerobic exercises like lifting weights. The body can transform excess blood glucose into glycerol, the building block of a triglyceride, which is how your body stores fat, if this happens over an extended period of time. Therefore, a glucose disposal agent aids in maximising the amount of glucose used for fuel during a high-carb meal, preventing it from being stored as fat.
