Here is another great site I go to often, she is so fun to watch on her little videos. Some great recipes too. I have been on WW for about a year now, and I have completely changed my eating life style, I feel so much healthier plus I have lost 30lbs. I too try to substitute healthier things in all of my recipes, once you get used to it, it just becomes second nature.
