AFAIK, there are several experimental results supporting low carb diets, but all are refutable, as in someone can always come up with a counter-argument. Robert Lustig and his "Sugar: The Bitter Truth" lecture (available on youtube) is probably currently the best-supported argument.
There's an initiative called the "Nutrition Science Initiative" (nusi.org) that apparently attempts to put an end to the debate with irrefutable research, which will finally convince everyone one way or the other. They seem to be still in the early stages.
