Been excercising/dieting for a little over a month now. I just started www.fitday.com about 3 days ago and all three days I have 3,000 cal intake and 6,000 burned. Is this really bad? I'm kinda scared about it. I know its good to be like 500 cal under, not 3,000. Should I eat a ****load more?
I don't feel weak or rundown. Just worried about it.
