Personally I believe that the Atkins Advantage Pre-Made Canned Shakes (especially chocolate) has helped me lose the last 7 lbs...I have one with breakfast with a little protein and it prevents me from snacking between meals (which was a problem - - even with legal foods). I am now at my lowest and I partially owe it to the shakes. The bars unfortunately have the opposite affect - the glycerine must do something to me since I get knocked out of ketosis and do not lose for a few days after I consume one.
