I like this particular thread, but I loooooooove reading success stories. Mine's not much of a success story, but here it is anyway.
Basically, I've been thin all my life and, after watching my mom struggle with her weight and self-esteem (she's only slightly overweight, but she used to be thin like me), I decided that I would rather prevent weight gain than try to lose weight 10 or 20 years down the road. Over the course of my undergrad and masters degrees, I slowly put on 10 pounds that I could pretty much put on or take off as I chose. The problem was that taking it off was getting harder and harder every time.
I've experimented off and on with a bunch of diets that didn't sound too gimicky -- I did the vegan thing, the USDA food pyramid thing, and those pre-determined diets from fitness magazines. Then I stumbled on primal completely by accident and gave it a shot. When I tried it, I was down to my "happy weight" and was just doing an experiment to see if I could lose some body fat for the summer, look more toned, etc. What happened was that in two weeks after switching to primal, even though I was still eating the same number of calories, I lost 7 lbs. I actually didn't know my weight could get lower, but it has, and even though I've increased my calories and decreased the amount of exercise I put in during a week, I've been very stable at my new weight. Even if I binge, I rebound quickly, and I feel better than ever.
So yeah, this is not an "I lost 80lbs. and found myself" kind of success story, but I think the fact that I beat the standard american diet is success enough for me!
