As a fellow PCOSer, I think that low carb diets are the best for us. I am insulin resistant as well, so I have been following the Insulin Resistance diet. So far, I'm losing...not as quick as on Atkins, but with the metformin that I'm on...I get too lightheaded on Atkins.

I would suggest to pick a lower-carb diet and follow that whether its Atkins, IR, SBD, CAD, etc.

GL!
