Also be sure to add
protein to every meal/snack, because
protein also keeps feeling fuller longer.
Protein can be in the form of meat, chicken, dairy (I've gone back to full fat dairy), eggs, nuts, etc)
I don't have PCOS, but I do have insulin resistance, plus hypothyroidism, and I find that as long as I add butter and/or coconut oil to every meal, I don't eat nearly as much at the meal, I need snacks between meals and I do lose weight.
