hope I can still join in on this thread...

I'm "lowfatpie" on MFP.
If I'm hungry I eat back my calories. I don't exercise to eat though. I also won't go and quickly exercise just because I overate. I look at what I had and figure out what I could do differently.
Then again sometimes I may go over simply because I really am hungry. That's life. Usually it all balances out after a while.
