The rule that goes 1.5 x your body weight (140 x 1.5) = 210 g of protein = 2800 cals per day. I don't think that is good enough. I want to go from 140 lbs to 180 lbs as fast as possible without hurting myself. I will be basing my meal plan on a 30% cals protein/50% carbs/20 % fat. How many grams of protein can I eat each day to get from 140 lbs to 180 lbs as fast as possible without hurting my liver/body? Thanks.
