Metabolism has to increase to incorporate a new source of load in daily life. When I started my job my feet were in constant pain but now I can stand for 7 hours with ease and I can stoop, kneel, lift with relative ease. That is just with 2 months from going from slug to lug. It takes too much discipline to hold an excercise routine for me but this new job is the right amount of activity without too much skelital stress. But if people drink monster drinks and eat candy bars while doing all this, it won't make much difference. I still eat candy. I guess I just don't plan on doing it daily.
