I only ask because some cat in the GAF fitness thread was talking about counting calories, and he was saying stuff like, for the week he'd be at 2,000 a day if you offset what he ate with what he burned off doing cardio, and I was like bro, you are eating in excess of your maintenance level by like... hundreds of calories.
Anyway you should eat more than 1500 calories a day and also eat more fat.
The average person would need a little under 2,000 Calories a day just to satisfy their
basal metabolic rate, or else their body would not be getting enough energy to do basic processes and would start storing fat. If the guy is actually doing an hour a day or something on an elliptical machine, then he would actually need probably around 3,000 calories to stay fit. In fact, if he burns around 2,000 Calories (which is only really only a threat during marathons) then he would get to
"the wall" where his body has no more glycogen left and if he has enough endurance/training, then his body would start burning the fat directly.
But it's safe to say that you should eat more than 2,000 calories on days that you do a decent amount of cardio.
