I'm about your age, diagnosed in my 20s, and heck yeah, I recommend eating low carb for PCOS!

My doctor told me "lose weight and your symptoms will improve." Ok, I tried. I ate low fat, low calorie... and my cholesterol went up (lots of small LDL), my blood sugar went up despite increasing doses of Metformin, I lost more hair, I had no energy, and my menstrual cycles stopped completely. And I gained weight.

I've been restricting carbs since January 1st and the weight loss has been fabulous. I'm even MORE excited, though, about my health improvements. I had my first normal period early in January and my cycles have been regular since. I have loads of energy and my skin and hair are visibly healthier. Even things like desperate urinary urges -- which I realized were usually triggered by eating something sugary -- have disappeared. I never tolerated Metformin well, so I weaned myself off of it (without doc's advice) and I feel terrific.

Give it a try.
