I have PCOS and with it I've learned comes insulin resistance. So basically if you want to cure PCOS you need to lose the weight and to do so you need to keep your blood glucose as even as possible, No spikes!
Think of foods that have high sugar, high carbs, or a high GI. Those are the ones you need to avoid. So yes that means pretty much o ly meat and veg with some nuts. Leave out the starchy veg like white potatoes. And maybe have sweet potatoes or butternut squash once maybe twice a week.
Always pair a Carb with a protein. So if you're going to eat an apple have some chicken. Trying not to rely on nuts as your protein source only as condiments.
While you're healing stay away from most fruits. Especially melons and bananas. I personally try to only eat berries and only when I have a super sweet tooth. But again I pair it with protein.
Pale cheats like honey and maple syrup are much better than sugar but will cause a huge spike making your body hold onto the weight so steer clear. I personally think of it as my ideal diet and my socializing diet. It's not about restricting yourself so much you can't hang out with friends and have a yummy fruit salad. Usually we get in the state we are because we're forging on the fruit and a paleo banana pumpkin muffin at home. Sure we're eating "paleo" but because we're insulin resistant we need to watch are intake a bit more.
