Hello. this is definitely a "Your Mileage May Vary" situation. The sugar alcohols (glycerine, maltitol, sorbitol etc) are not supposed to elicit an insulin surge, so they are considered neutral for a low carb diet. So the legal carb count is 2.5 or so. So they are legal and you didn't blow it.

HOWEVER, many people find that they stall while eating the bars. So I think you'll just have to try them out and see how you do. If you stop losing, then suspect the bars first.

I know they are handy but..... maybe not worth the convenience.

If you click on this above, you can search for "protein AND bars" and find lots of threads with great information on this site.
