There is no magic pill. Green coffee bean extract won't make you lose tons of weight or anything. There's no evidence at all that it works (what early studies have been done are not compelling) and the jury's still out.
I think the reviews on Amazon.com got such products speak for themselves.
Don't look for an easy way out. There isn't one. If there was, we'd all be doing it, and we wouldn't need Sparkpeople at all. Taking an unregulated herbal supplement will not make you start shedding pounds with no effort at all. If it was truly that effective, it would be patented by the drug companies and being sold in massive quantities for lots of money in drug stores everywhere!
