How much protein do i need to be eating daily? I'm a 5'8" 160lb female .. i do cardio 1hr a day 4-5 days a week ... i just started eating protein bars b/c someone suggested i wasnt getting enough calories and did not have near enough protein to loose weight ... Yesterday i ate more protein than i think i have in my life but fitday says its still only like 25% ... but the protein bar i ate said 30% so how come those don't correlate (given i also ate another protein type bar with 20% and a bunch of chicken) ...and yall reccommend staying below 30% fat for the day right? Also what is a ideal amt of calories for a protein bar? is 200 good or is that too many? Seems like i'm eating too much to be loosing weight especially since when i was eating less i didnt really loose then?
