safecracker is right on again with that tidbit of advice. I am on the endo side of things, and a year ago, I gained a lot of weight. Tried every diet in the book, including Atkin's, nuttin' happened. I said screw it, it's all about the metabolism, which I kinda knew already, but didn't think about consciously. I started eating smaller portions of healthy food more often in the day (5-7 times), and slowly but steadily dropped 35 lbs. I didn't really watch fats too much, but I did watch refined sugars, white flour, and trans-fats, i.e. hydrogenated oil. I am just 9 lbs. away from my wedding weight 5 years ago, and all my suits need to be altered.
I also eat anything I want now, just in moderation.
