Even taking the sugar out and replacing it with other super sweet chemicals may not help that much as this article about new research from Australia explains:

It seems that artificial sweeteners may also impair the body’s ability to control glucose. It’s only one study, but, given that the insulin response to food intake begins when you pick up a menu, it makes sense to me that eating any sweet things (and artificial sweeteners are really sweet) is going to mess around with your insulin.

If a sugar free sugar drink was ever an answer, what on earth was the question?
