i always read " bsaed on a 2000 calorie diet" why 2000? do i have to have 2000? i figured out im taking in about 1,085 before workout,( we have a pretty good size gym at work) then go home and eat dinner. so is that enough or what. i heard you need to burn more then your intake, so if i do that, am i ok at 1,085 or do i need the full 2000?
