I lost weight with Slim Fast with Soy. This was best Slim Fast they made. I went from a size 16 to a size 8. I did not csereixe at all. That was in 2005. I have tried it again in 2011 and it was not the same, i was still hungry. Anyway, i am going to try it again, and stick to it. Eat breakfast and light meals. But, i will not deny myself any of my feel good foods. Maybe i will put before and after pics. Good luck to all of you who are losing weight with slim. Great product!
