I also found problems while eating Atkins breakfast bars and Atkins candy bars. It seems like b-fast bars cause more stalling for me than candy, but I'm not taking a chance.
When I stopped them both, the weight has started dropping again. For now, I'll just leave them alone.
They taste great, but not at the expense of my weight loss.
However, everyone is different. If you want to give it a try, see what happens, but be prepared to stop if you see a stall.
