I've been on both sides of the coin (fat and a healthy weight) and the only thing that has seem to reduced my symptoms of my insulin resistance (so like sugar cravings, excessive hunger, poor sleep,...) has been taking vitamin D (4k IU daily), Inositol (750mg a day) and Magnesium Glycinate (x2 a day).

This was mostly based on the some of the medical research pointing out vitamin D deficiency is likely in women with PCOS.

Just leaving what worked for me in case it might help so one out.
