This is on his site under FAQ and it doesn't even mention the sugar alcohol issue.

I love this WOL as well and thank Dr. Atkins in my heart at least once a week but calories I can up. Sugar Alcohols stall me and others and I know this is how he makes $$ but it should be mentioned!!

Slow Weight Loss and Plateaus
FAQ 1-10 of 10
Could eating Advantage bars be impeding my weight loss?
This varies by individual. If you have reached a plateau and are not losing weight, try omitting the bars until weight loss resumes. Alternatively, you could exercise more to burn the extra calories or try eating only half a bar. Remember, each bar contains approximately 220 calories and these added calories could be affecting your overall weight loss. The controlled carb way of eating has an advantage over low-fat diets in that you can take in more calories and still lose more weight, but don’t regard that as a license to overeat.
