Well... How many calories you think it takes for fella like Jay Huge Cutler to gain one pound of muscle tissue?
So many variables to consider. . . A guess; with all the pharmaceuticals that Jay takes and with all his muscle, his BMR is obviously sky high.
-When Jay's not training he does
not lead an active life style. He doesn't go snowboarding or ride motocross. He doesn't practice the Martial Arts. He doesn't go hiking on Mt. Charleston (near his house in Vegas). Hell, he doesn't even wash his own car or mow his own grass.
-It is absolutely impossible that he would NEED anymore than 4,000 - 5,000 calories per day to add any muscle.
450 grams of protein per day = 1,800 calories
500 grams of carbs per day = 2,000 calories
150 grams of fat per day = 1,350 calories
That's 5,150 calories per day and that's huge. I can not fathom Jay would NEED more food than that to gain muscle. If he does, hell, I guess he just does.
