I think you are referring to this article: How fat and obesity cause diabetes I saw a deconstruction on someone's paleo blog but now I can't find it. The headlines for these things are always wrong. The study wasn't about how fatty diets cause diabetes at all. It's about beta cells and obesity, and to get the mice obese they chose mice prone to obesity and fed them a horrible diet high in carbohydrate and artificial fat. But that doesn't make for a flashy headline so they made up a better one. Anyway, there's a link to the full-text on the page.
