    I worked it out on MFP and 128g of protein seems like alot to me - Im 155lbs. About 23% bodyfat. 5'9" And if fat and protein are both supposed to be 30% then why are the # of grams calculated so different from each other????

    because there's 9 calories per gram of fat, and 4 calories per gram of protein. Therefore, if 30% of your calories are supposed to come from fat (510 calories), dividing that by 9 yields the 57g. Same goes for protein (510/4 =127.5g)

    Is that how you lost 82 pounds? that's amazing!

    Great thanks! I still think that 128g of protein is too much. Should be 1g per lean body mass, right. So prob about 115g of protein for me or no???
