Just reading your post here. There is a lot of great research available on the web about sweeteners (essentially carbohydrates). Diet Doctor.com is one such resource that comes to mind. Dr. Jason Fung, author of The Obesity Code has also talked extensively about this. I am sure a Google search will pull up a lot of information.
I can also recommend a book by Gary Taubes called, “The Case Against Sugar”. VERY eye opening!
