Hi.. I have PCOS and insulin resistance. It can be a real shock trying to lose weight. I did try weight watchers for about a year and found myself starving, my cycle even more erratic and very little weight loss despite sticking to the points.
Then I decided to start really researching. PCOS is a nebulous term that has many aspects to it, not all of which each woman has. For me I started to keep a journal with food, sleep, exercise, my cycle, and emotions etc in it. I started to work out that if I take the chromium supplement as well as vitex (a herbal hormonal regulator) that my cycle fell into line and I wasn't losing weight - but for a change I wasn't gaining.
Then I started to low carb. I felt fairly crappy on that to be honest. So I switched to south beach. I like the approach of having a detox - which helps your insulin sensitivity and then gradually adding carby foods back in to see how you feel. For example I feel fine eating potato but pasta and bread made me feel ill and too much of it will cause some haywire cycles.
I think that it is also important to get at least 30 minutes of exercise a day. Maybe start with a pedometer and just see how much you do over the course of a week. Some days I am low, other days when I am at uni are mega step days and make up for it. But as a rule I try and get in 30 minutes of something extra per day.
I have slowly lost weight.. about 36 pounds your measurements so far and that has been since really starting at the beginning of the year. I feel good and don't starve myself and have loads more energy. But I think at the core of it is actually listening to my body and respnding to what it personally needs rather than what someone is telling me. So after this very long winded post
I would recommend starting to experiment and see where it takes you
Best of luck
I know that the diagnosis can be really sad, but perhaps it will help to generate the solutions you are after.
