You're so right Jan...everyone is different! :)
I've never seen anyone tho, lose weight with a "diet" (i.e., cabbage soup, Atkins, grapefruit, Nutrisystem, or Jenny Craig) that didn't gain it all back...because as soon as you quit eating the prescribed foods, you're back to where you were when you gained in the first place.
I still eat everything I want to eat, I'm just more aware... I read labels, and stick to one serving. That pizza is NOT the last pizza in the world...a large salad and one slice is enough. I can have more tomorrow if I really want it. Oh...and watch those salads! If you load them with bacon bits, cheese, and ranch salad dressing, skip the pizza! ;)
