I'm the same as
rockinrobin, my exercise is for the in vs. out equation, I want 500 more out than I put in, to give me a deficit of minimum 3500 cals a week = 1 pound. I tend to eat after tha gym as part of my meal plans anyway as I'm usualy hungry, but my calories stay the same whether I go to the gym or not (about 1200-1500). My sessions are usually between 500-800 cals (though I did a monster sesh last night at 1000!).
I guess what I'm saying is, for weight loss, what works for me is burning more than I'm eating (as in BMR + exercise, not just burning my consumed cals!) And as long as you are safe and are eating enough for your body to continue functioning and healing etc, I don't see the need for extra. I'm not a trained Dr or anthing, it's just my opinion, but it works for me
