I'm doing pretty darned well!
Turns out the diet game I'm playing is called Game On! Here's the website for it, although there is a little bit of language, just so you know. And here's a book review that's pretty comprehensive.
Essentially, it takes the principles we already know - eat lean meats, eliminate or greatly reduce sugar, drink a lot of water, get rid of soda, get enough sleep, exercise - but it turns it into a game and you either get points for healthy behavior or lose points for unhealthy behavior. For some reason, this approach is really working for me. Since last Thursday, I've lost 4 and 6/10th pounds. Woohoo!! You get a day off and you get a meal off some other time during the week, and you also get 100 calories a day to spend on whatever you want, so there is some leeway.
I'm a pretty competitive person, so knowing that I'm working for a team effort is really helping me. There are three people on my team and three on the other, and our points are being added up and compared. I haven't heard this week's tally yet - yesterday was check-in day - but I feel good about my contribution to the pot. I really am focusing and trying hard to stay on target, and it's showing ... in addition to the weight loss, I've lost an inch off my hips and an inch off my waist. Woohoo!!
