During weight training we use glucose from our glycogen stores as a fuel source. This means that at the end of a hard workout due to the fact that your fuel is low we enter a catabolic state, uh-oh! To prevent this we should focus on consuming some quick diegesting carbs to spike our insulin levels so that we can jump back into an anabolic stae where we want to be! An excellent and highly efficient way to achieve this is by drinking grapefruit juice both during annd after your workout in conjuction with a source or protein.
