...though I have heard of it (seems to be a regional thing to me - some diets seem to be more popular in different areas - maybe it's a cultural thing?)
A TERRIFIC site to check when considering taking dietary supplements is
www.quackwatch.com, run by Stephen Barrett, M.D. who has been fighting medical and nutritional frauds and quackery for 30 years now.
Here's some interesting links from the Quackwatch site to check out:
http://www.quackwatch.com/01Quackery...ightindex.html - Weight Control: Products, Practices & Theories (includes links to articles on chromium picolinate and chitosan)
http://www.quackwatch.com/01Quackery...uppsherbs.html - "Dietary Supplements", Herbs, and Hormones (a brief article summarizing the DSHEA, and including numerous links to articles on various products, etc).
I admit, I'm a skeptic - take heart though - my mission is to pass on what I've learned through 30+ years of either dieting or reading about dieting (at absolutely no charge) and to urge all readers here to do a little TRUE research on these so-called "miracle" weight loss products before charging them to your Visa card! I provide myself as proof positive that the only true way to lose weight and keep it off PERMANENTLY is to eat right and exercise...and educate yourself.
Take care!
