This has been discussed at length on the forum. In the interest of avoiding duplication, I have merged your question with an existing PCOS thread. You are also welcome to google "Whole30 PCOS" for other threads and discussions.
I was diagnosed with PCOS a while back. My doctor put my on metformin, then I got pregnant and stopped. I have been un-medicated since then. I am post Whole 30, but due to my success in that 30 days, I'm continuing to follow it (more or less). I'm definitely staying off wheat (check out the book Wheat Belly). Anyway, I lost 15 lbs in that month. I take yoga once a week and occasionally walk. Nothing major. Post Whole 30, my weight continues to go down, but it's not melting off like it did at first. I highly recommend it. The only change I made was eating goat cheese. Man, if I'm going to eat a salad every day, it's going to have goat cheese in it.
I'm starting today -- a day behind you two. I'm worried about the cravings.... Just thinking about thw 30 days last night, I ate some farewell chocolate and drank some milk. I'm pre diabetic and have only one adrenal gland. So sugar is a big no-no. But I like it so. I like to walk and ride my bike for exercise, but the family hustle gets in the way of taking care of me. Can you relate?
