Exercise and a good diet are virtuous cycle. However, as someone who runs a lot (7-14 hours/week), I can tell you that there is such a thing as being rungry. I actually find it easier to lose weight when I'm on the lower end of my mileage range. Also, it's easy to think "I ran so much, now I can eat more," which is a dangerous trap.
