I was diagnosed with PCOS last month. Here's the deal. No matter how many calories you burn (eating 1200 a day and burning 1600) you will see very little weight loss. Bouncing 20 pounds in either direction is quite normal for PCOS patients that are not on the Insulin Resistant Diet. You have to eat more protein than carbs and the diet is very strict and, if you do Ideal Protein or ProtiDiet, the food can be hard to adjust to but it is needed to lose weight with PCOS. Since starting the Insulin Resistant Diet and exercising 3 days a week, I've lost 25 pounds. I'm full (maybe not happy with the taste) and I don't have cravings for anything not good for me (except the occassional Pepsi). Now, the reason your body is different from someone without PCOS is your body sees carbs and produces TOO much insulin to break it down. When you have too much insulin in your body, it stores as fat. So, you see, no matter how many calories you burn, if you're not eating more protein than carbs, you'll never lose more than 20 pounds.
