Hi i lost some weight and im still trying to maintain it right now im 147ish i gained about 10lbs in the past couple of months because of medication im on and it went right to my belly which is frustrating me because now i want to lose more weight but my dr tells me i should gain weight/muscle, but i cannot seem to gain muscle i eat about 120+g protien a day and do some weight lifting and treadmill daily but i cannot gain any muscle, anyway im wondering how many calories based on my weight(147) height(5'10) and age(22) and activity level(moderate) and so such do i need to maintain my weight? I used a calculator and it said 3100cal but that seems like alot, so i think somethings wrong. Also how important are carb/fat/prot ratios in the diet? I eat quite a but of carbs(alot of fiber about 75g/day) and low fat, like less that 40g day. Im just not sure what to do anymore i feel like i have been doing it all wrong and my food is all messed up but i have been eating the same way for like the past two years which is about 1 year to lose it and another year maintaining. Any help would be great.
