hhchick, it sounds like you've found a plan that works well for you. If it were cheaper and offered a full week of meals instead of 5 days, I'd try it! I'd just have to figure out what to do about the meals that come in at just under 500 calories, though. I wouldn't lose weight on those.
Good luck and best wishes on your weight loss journey. It's never easy, no matter what plan you choose.
