[link|http://www.fourmilab.ch/hackdiet/www/hackdiet.html|The Hacker's Diet]. I haven't tried it myself.
I haven't tried to do what you're attempting, but I'm half-heartedly working on losing about 10 pounds. (I need to apply myself more.) A few things I've figured out over the years (YMMV):
1) Eating is a habit. The pangs that I feel around meal time aren't hunger, they're just my body telling me it's time to eat. Skipping eating for a day reminds me what hunger pangs are like.
2) Cutting out cheap calories is relatively painless. Don't drink sugar/corn syrup sweetened beverages. Substitute water. 100 calories is ~ 10 minutes of fairly vigorous exercise. A pound a week is 3500 calories per week (500 calories per day, 7 days a week). If you go out to dinner, don't eat more than half the meal. Take the rest home.
3) Carbs generally make me hungry. Don't snack on chips or pretzels or candy bars. If you must snack, eat fruit or carrots or beef jerky or something other than grain-based carbs.
4) If you snack when you work or when you relax in front of the TV (or whatever), find another habit to do while you're working. Don't let habits cause you to eat more than you should.
5) Exercise makes you feel less hungry. Make time to go on a regular evening walk with your sweety. Get a dog if you don't have an excuse. It's relaxing and good exercise.
HTH a bit. Good luck!
Cheers,
Scott.
