So losing weight releases the estrogen in your fat cells? I hadn't heard that. I do know that I have been having a terrible time the last year with my periods, winding up anemic. My holistic doctor blames this on excess estrogen. I've been avoiding soy, for one thing. But I've also lost and regained the same 15 pounds about 3-4 times in the last year. So maybe I need to just lose it all this time, and see if that helps! Diana
