I have tried a few things and writing down what I eat does help. Next week I am going to try something new. It may not be for everyone but for 21 days it won't kill me if I don't like it. I have looked at the recipes and there is no junk food involved, which is my weak spot. It is the 21 day Vegan Kickstart. If you are curious here is the web page.
