I probably sound like a retard for asking, but I just can't seem to wrap my head around it. So let's say you take in 2000 cals a day to maintain, and you're trying to cut, so you cut out 500 cals a day giving you 1500 cals a day. As a result you will lose a pound a week, 3500cals in a pound. That's all fine and well, but what happens when you start doing cardio? If you did cardio and burned 500 cals a day. Wouldn't that put you down to only taking in 1000 cals a day and your body would think it was fasting? I'm probably wrong about this, but if that's not how it works then how does it?
