Treating insulin resistance with anything but a low carb diet and bringing out the old canard that low carb high fat is dangerous. When my wife developed gestational diabetes they gave her a high carb "balanced" diet to follow, blood sugar monitor and the humalog or whatever insulin prescription to use when the diet failed! They warned her to stay away from fat. They were sure she was going to be on insulin. She trashed their diet and went back to the way she was eating before she was pregnant (Atkins). They were amazed at her blood sugar readings. The doctor literally could not believe that she wasn't going to need insulin and said everybody with her test reading needed it.
Most insulin resistance can be treated with atkins. Read his book and Protien Power. They are very edifying.
