Thanks, Stephen. That puts the story in perspective. I agree with Colin; if you want to lose weight, eat right and exercise. I know, easier said than done, but there it is. It seems foolish to me to rely on extract of [fill in the blank] for something, when the solution is dictated by common sense.

A few comments on this: Yes, the study was on a commercial product. The
journal the study is in is publically available. The study was on 16 adults.
The activity/effect is postulated to be due to the chlorogenic acid in green
coffee beans. I assume the research was paid for by the product
manufacturer. The study still has to pass peer review to be published, and a
lot of good work does come from studies funded privately. 
The problems are 1) negative studies can be suppressed (unethical, but
absolutely occurs); and 2) studies are often referenced in biased press
releases or written about by writers incapable of forming or putting forth
critical analysis of the study. You can't tell the good from the bad based
on headlines or most newspaper article, though a good science/medical writer
can give a very informative newspaper review.
In this case, the protocol was sound, but the population (16) was small. The
substance shows strong promise, but the study isn't definitive.
Nutraceuticals aren't subject to the rigors of testing required for
pharmaceuticals. The funders have no motivation to do large studies or
meta-analyses because they are able to sell product based on "x number of
studies" suggesting confirmation of the desired effect. They know buyers
won't read and analyze the studies, unless they're biochemists (like me). 
The effect isn't due to caffeine. The subjects did not have increased heart
rates. The lack of caffeine and the effective ingredient cited tell one
exactly how to make the extract, but not how concentrated it is. The study
referenced how much of the commercial product was given to the subjects, but
without knowing the chlorogenic acid concentration in the product, we don't
know how much of that was delivered; nor are we aware of any buffers or
other pertinent ingredients. 
So I can tell you how to extract chlorogenic acid at any concentration from
coffee beans (but wouldn't - if you knew how to do it safely, you wouldn't
need to be told!), but not how to make the product.

The green coffee extract product become a commercial name now, GCA (TM).

That just make me feel its an ad for selling their product.

Probably there is something increasing burning fat.

But I still feel the fresh food and regular exercise is the only way to go.

I saw a bunch of headlines regarding this study as well.  I don't think I
have access to the journal the original paper was published in though.  I'm
curious how the "green coffee extract" was produced, and whether this might
be a viable use for the odd bits of leftover greens that I might have laying
around.  Anyone know how this "green coffee extract" gets produced?

Personally, I think it's due to the caffeine content.
