Dr. Harriet Hall writes about it:
Dr. Oz has promoted a series of weight loss supplements on his show. Raspberry ketones were presented as a fat-busting miracle, thengreen coffee bean extract was touted as “magic,” “staggering,” and “unprecedented.” And now both of those miracles have apparently been superseded by an even greater miracle: Garcinia cambogia extract.
Dr. Oz calls it “The newest, fastest fat buster.” A way to lose weight without “spending every waking moment exercising and dieting.” “Triples your weight loss.” “The most exciting breakthrough in natural weight loss to date.” “The Holy Grail.” Oz claims that “Revolutionary new research says it could be the magic ingredient that lets you lose weight without diet or exercise.”
