I count calories and keep a written journal on my calendar of when I work out and for how long. Everyday, I try to improve on what I've done the previous day. Like, instead of having 110 calories of rainbow sherbet, I try to make it something healthy instead, like an apple. I don't like putting something in my mouth that will cause something negative to happen to my body. You eventually get to a point where you feel so run down and queasy if you have something greasy.
I am the type of person who thinks about food 24/7, and I always need something in my mouth, so I eat a lot of celery. It's mindless munching while I'm sitting in front of the computer. It's annoying, but at least I've figured out that I can control it with celery (and water)!
Anyway, sorry if I'm rambling, but that's what works for me. How much do you need to lose?
