I'm writing for moral support. Don't weigh yourself!
There, now don't you feel better?
Just kidding! I think once you settle into the program and your body gets used to high starch/fruit/veg, you'll stop worrying about your weight once you see it coming off dependably. I'm in Weight Watchers (I was in OA a couple of times and even CEA-HOW, but the 12-step thing just doesn't work for me), and I do weigh myself each morning, because I don't want any nasty surprises going into the weekly weigh-in at Weight Watchers. Besides, I like to know where I am. Give this program time to work, you'll be fine — and don't worry about your 62 year-old metabolism, mine's 75!
