Without reading the studies there is just so much more I want to know. Initially, I think this is just a marketing ploy by Big Pharma to keep people medicated. Where as recently I have met a number of women who have lost significant weight through diet and exercise and also gotten themselves off all sorts of meds.
Still, as I was reminded just the other day I live in a very appearance conscious city. Not a health conscious city. And it is much better to focus your efforts on vanity than improving anyones health.
