Reading through this thread has been illuminating. I'm obese by definition but I'm constantly told that I eat like a bird. I don't snack between meals a lot. My weight has not fluctuated over the years, but instead tracks right alongside the inflation rate.
Probably my biggest sin is caffeine consumption. I have an energy drink once a day every morning. If I don't, the headaches I get by the afternoon sure let me know in a hurry. Occasionally I have a pop to drink for lunch. I've learned that caffeine in the afternoon/evening disrupts my sleep so I've cut that out.
I have managed to cut pop out once in my life and promptly lost about 15-20 pounds. As with most vices though, you start to feel invincible again and think "ah hell I can manage it".
My current goal is to ditch caffeine again, but I was wondering if anyone else had advice regarding this goal. My poison of choice is Mt. Dew's Kickstart drinks, so I think what I'm actually chasing is the sweetness that those drinks provide.
