Saffron is, biologically speaking, the dried stigmas of the crocus flower. It’s orange in color and used culinarily for its color and scent. It contains small amounts of terpenes and other organic compounds (like safranal) which are weak antioxidants and mild anticonvulsants, but as you might imagine, saffron extract does not cause a person’s appetite to be diminished. Nor does it cause thermogenesis (the most common pharmaceutical method of weight-loss.)
Like many of the supplement fads of the past few years, it was pushed by Dr. Oz, a television doctor who is paid by supplement companies to promote their products. Dr. Oz has also been directly responsible for the Garcinia Cambogia fad/scam, promoting it heavily in 2012 despite widespread scientific studies showing it has no appetite-suppression or thermogenesis-promoting properties.
Before garcinia, Dr. Oz promoted green coffee-bean extract and raspberry ketones as weight-loss supplements. No peer-reviewed study has proven that either of these supplements induce weight loss, either.
Given the fact that Dr. Oz has a history of promoting homeopathy in addition to one weight-loss scam after another, it only stands to reason that he’s published a book called “You: The Owner’s Manual,” a book that tells you how to be healthier and younger. It’s a #1 New York Times bestseller. It has sold over a million copies.
