I really don't know the answer to that but I can take a guess. Because of the sugar content in Skinny Cow products (even the fat free) my guess would be no. But they are coming out soon with a low-carb version that has 3 impact carbs per bar:they don't list the sugar content on these , however.
I went to
www.skinnycow.com for product info.
You are allowed sugar free popsicles and fudgecicles (75 cals per day).
