I have a feeling that PCOS is in fact a selective condition. My best girlfreind is overweight as well but its just that, shes over weight. In her words "I just like cheese too much". I on the other hand would be quite content with a loaf of bread. Being rather symptomatic every cyster has all kinds of different symptoms. Some cysters might be over weight some cysters not. It is usally how our body reacts to the paricular imbalance in our systems.
I believe it is totally possible to be overweight or thin and not have the condition. Obesity is a symptom of PCOS not the cause. For example, if I didn't have PCOS I would look like my family (tall and thin) but since I have it I am overweight because I am IR. Also, those who are overweight and have family that is just overweight will be overweight. Obesity is genetics, environment and imbalances in our systems its just not one thing.
If PCOS was a diesese then perhaps it would be possible to pinpoint a person who has it. Unfortunatly, its a syndrome meaning that there are a whole list of symptoms....like prunepie said "there is no one size fits all for pcos". The best thing you can do is to deal with your own individual symptoms and secretly hate the BBW that has the nice skin...lol. GL hon, hope this helps...
