Here is an alternate view of Type 2 diabetes that I think makes a lot of sense.

"The classification of Diabetes as a failure to metabolize Carbohydrates is a traditional classification that originated in the early 19th century when little was known about metabolic diseases or about metabolic processes. Today, with our increased knowledge of metabolic processes, it would appear quite appropriate to define Type 2 Diabetes more fundamentally as a failure of the body to properly metabolize Fats and Oils as well as carbohydrates. This failure results in a loss of effectiveness of Insulin and in the consequent failure to metabolize Carbohydrates. Unfortunately, much medical insight into this matter, except at the research level, remains hampered by its 19th century legacy."
