Keto does have a lot of controversy, but I will tell you; I started it in May 2017 and kept up with it off and on till the end of January this year (several month breaks in between) and I went from 286 to 248 on it. Not only did I lose weight but I started having regular periods every month and my insulin resistance was under control. I thought it was a crazy diet at first, but I have seen it work wonders. I lost over 10% of my body fat and that's what caused me to be regular again. I now take @Metformin and just eat right and @exercise to regulate.

I've been told the Mediterranean diet works great personally I've used the keto and had great results with keto there's lots of controversy

Diets work differently for everyone. The best advice I can offer is to get a very good dietician with PCOS experience. Also document all food and drinks. You want to take in more protien than carbs.

My doctor said 40% carbs, 40% protein, 20% fats. She said 1,200-1,500 calories a day.
