Jody,
One thing I would caution you on with the Atkins diet - many many people have problems when they don't take in ANY carbs at all. I was horribly sick on the diet until I realized what was wrong. But, I kept doing research and found something that you might be interested in. I have PCOS. I was SHOCKED that my dr would recommend a "lower carb" diet for me. He told me not to abandon carbs altogether, but just to not make them the focus of a meal. Try to eat a salad and some meat if you have pasta, etc. Ultimately I went on the Heller diet (they have a couple of books out) which I "tweaked" a little. I had no carbs for two meals a day. The 3rd meal, which usually for me was dinner. I had equal portions of protein, veggies and yes, CARBS. I used to eat protein bars for breakfast, chicken breast with salad for lunch and awesome dinners like steak, salad and CHOCOLATE CAKE! Sugar is my weakness. I lost about 30 pounds in 2 months and I was so content because I looked forward to that one yummy thing I could eat every day without guilt. I also had cheese, peanuts and veggies with dip as snacks, even though they tend to have some carbs.
Just a thought. I would hate to see you get sick and abandon your strategy. Oh, and I've been told that you should make sure you get plenty of potassium when you're on that diet too.......
Unfortunately, my weight has little effect on PCOS. I have not ovulated - not ONCE - since I was 18 years old without meds. I was off the pill for more than a year and did not ovulate at all during that time.
