So I've been on this diet, and I've lost 3.5 pounds so far. It's actually a lifestyle change that I've made several times before but couldn't make stick, so this time I'm trying out an online calorie counter to give me some solid data. What I've found is that all my extra calories come from boredom snacking. If I stuck with meals, even if I stuffed myself I'd be having fewer calories than while eating Nutty Bars and Cheetos several times a day. By watching my moods and habits and cravings without judgment, I've been able to identify the trigger points and maybe some day I'll be able to completely overcome those challenges and let my skinny self come back out.
A big motivator is my kids, rather than simply my weight. I'm okay with being this size, as long as I come about it naturally and not because of some idiotic behavior I can't overcome, but my children give me signs that I haven't taught them what food is for. I have to do better, be a better role model so they will grow up healthy. That's a bigger motivator than the scale or tight clothes.
