It will say something along the lines of total carbs 17g, of which sugar 2g, of which polyols 15g.
Polyols are artificial sweeteners (maitol etc) and have a negligable effect on blood sugar so they are not counted as 'carbs' for atkins purposes.
They do however act as laxitives in some people.. the same reason normal sugar free sweets and chewing gum say 'excessive consumption may cause a laxative effect'.
It is generally recommended that you do not go above 15g per day. I am fine if I have 2 atkins bars in a day.
Some of the atkins bars (seems to be the american available ones) do say on them sugar alcohols 0g. I believe this means they do not have polyols in them.
I did atkins a few years ago, and started again last Dec. I have at least one of these bars a day and have had no problems with my losses - usually 4lb a week.
I normally have the cinammon bun bars for breakfast as I do not have time/cannot stomach anything savory first thing. I also sometimes have one on the way walking back from the gym as a bit of a pick me up. The Advantage bars are all pretty alright, daybreak I dont like except cinammon, and the endulge solid chocolate ones are :jelous:
Most of them do say suitable for all phases of atkins including induction.
I agree that it is best to eat the majority of natural unprocessed food, but for me these are a lifesaver.. I think I would go a bit barmy otherwise.
Boots do sell them, but only a limited range. They also sell their own range of diabetic chocolates/sweets. The chocolate wafers are very nice, and the solid chocolate much better than the atkins stuff. oh and the chewy toffees are yummy... but be warned.. they have 6g polyols each.. I found this out the hard way :8855:

I get mine from

If anyone wants to know what other things from there are pallatable or not then let me know.. some of it is great some erm... really disgusting.
