I did CAD for two years before I tried Atkins then I did Atkins for around 10 months. CAD for was very successful as I have gone from 265 pounds to 207. It has taken 3 years but I feel I can do this forever. I lost the bulk of my weight off CAD. Before I tried CAD I was thinking of going to have my stomach banded. I could not understand why I was so hungry all the time. I am sure you will find it very successful
