If you keep losing, you are one of the people who are not stalled by sugar alcohols - the "total carb" count.

But if you stall until you cut them out, then you'll know that you are affected by the SAs.

The sugar alcohols are "not supposed to affect blood sugar levels" and are considered 'inactive' so the manufacturer says you don't have to count them.

you'll just have to try them and see how it goes.
