Hi, I use them and a variety of other lc bars for maintaining. I did also use the tesco lc choc chip ones when losing on CD - with the blessing of my CDC - as the CD bars kicked me out of ketosis. I use the bars when I'm travelling or at work meeting when they're serving high carb or generally unhealthy food. I keep them in the car in case I get held up and am starving.
The best bit is people at work think I'm having chocolate and say things like ' you'll never keep the weight off like this' bless.
