Hi Becki,
Keep in mind that the number of calories burned you see on any equipment at your gym, should be considered gross a estimate. I would not put to much stock in those numbers. The important thing to remember is that you should be working with intensity each session. If you routinely work with good levels of intensity, it will help you burn calories at a good level that will help you in your quest to lose weight. I would not worry if the machine says you have burned more fat calories than you are allowed for the day.
Good Luck,
Paul
