Advice pls! Just got diagnosed with PMOS and insulin resistance

Hi everyone I just got diagnosed with PMOS and I’d like to know any tips or tricks with weight-loss or dealing with the symptoms.

The supplements and vitamins I just started on are Myo-inositol and D-chiro, Vitamin D3, Folic Acid, Magnesium, Zince and Omega 3 fatty acid. I’m really new to this and my doctors only advice was to eat better and take a Myo-inositol.

I am really hoping to lose 80-100 pounds to help with my symptoms. I have also been having really bad anxiety about possibly being infertile due to my periods being very irregular.

So pls if anyone has any advice or tips lmk! TIA :)
