I've been following the debate. It's way over my head, but it's been interesting.

But wouldn't the proof be in the pee, so to speak? If glycerin as a sweetner is bad, won't it toss one out of ketosis? That seems like a fairly quick and easy test that almost anyone can perform.

BTW: Anyone know where I can buy glycerin for cooking? I have a ice cream recipe that calls for it, I think more for texture than anything.
