Gosh, I'm almost embarrassed to admit how many diet/motivation/exercise books I've got. I'm a bit of a junkie that way.
I'm currently reading The Thin Commandments by Stephen Gullo, as recommended here on 3FC by RockinRobin or Meg, I think. I really like it; it's got some very unique ideas I haven't come across before.
I have never, ever, not even one time regretted not eating something. Never. Not once. Turns out telling yourself no feels marvelous. No deprivation passing up on *those foods*. The deprivation is EATING them and remaining overweight. You've got to raise your standards; requiring more from yourself. Challenge yourself. Push yourself. Work past the discomfort. Every time you do it, it gets easier and easier - Rockinrobin
