I disagree with some of the points of this article. One of the sugar alcohols -- erythritol (4-carbon) -- is only slightly metabolized. Most of it is lost in the urine, so it supplies almost nothing in calories.

Xylitol (5-carbon)is metabolized through the pentose shunt, which promotes ribose and nucleotide and protein synthesis, thereby helping to retain lean tissue. It could be reassembled into glucose, but this is a roundabout path. I have used 20 grams per day without affecting the keto stix. Xylitol is good for teeth; use xylitol gum or mints after eating.

A portion of the ingested sugar alcohols does reach the lower gut where it does behave exactly like soluble dietary fiber. That's why eating too much causes diarrhea.

Sucralose is chlorinated sugar -- trichlorosucrose. I use a little but I am wary.
