According to this article, coffee made with green (unroasted) beans speeds up fat-burning in the body because it contains high levels of chlorogenic acid, much of which is destroyed by heat during the roasting process:

Since chlorogenic acid is an antioxidant and reduces glucose absorption, it would seem to be a beneficial substance. However, according to this study, it can also increase homocysteine levels in the blood.

Also, since caloric restriction is associated with a lowered metabolism, I wonder if raising metabolism (with chlorogenic acid or with green tea, say) might have a negative effect on longevity. Or would a decrease in body fat make up for that?

I bought some green coffee the other day without realizing that I had to roast it. It tastes kind of nasty, since I continued to make the coffee without roasting it. Maybe I'll try a couple of cups a day out as a "cutting aid".

Never, ever try to put green coffee into a burr-based grinder. It will jam it and possibly ruin it. I assume you're using a whirly-blade grinder.

According to the article, it's the transformation of chlorogenic acid into "brown aromatic Maillard reactants" through roasting that gives coffee its delicious flavor and aroma... that's why green coffee tastes bitter.

Various plant leaves also contain chlorogenic acid, and I've seen it mentioned on the labels of artichoke-leaf and blueberry-leaf supplements... so you don't have to drink raw coffee to get it.

Anyway, just based on this article, I guarantee that within six months virtually every manufacturer of diet supplements will have a "green coffee" or "chlorogenic acid" product on the market.

In fact, if anyone wants to make a million bucks, here's a great tag line: "Eight times the fat-burning power of green tea!" Send me 10 percent of the profits, and it's yours.

"Eight times the fat-burning power of green tea!"

WOW! That does sound catchy, - you've just there handed out a gold mine. [lol]
I can just imagine the crowd going absolutely crazy over such salvation.

Inhibitory effect of green coffee bean extract on fat accumulation and body weight in mice.

Shimoda H, Seki E, Aitani M.

ABSTRACT: BACKGROUND: An epidemiological study conducted in Italy indicated that coffee has the greatest antioxidant capacity among the commonly consumed beverages. Green coffee bean is rich in chlorogenic acid and its related compounds. The effect of green coffee bean extract (GCBE) on fat accumulation and body weight in mice was assessed with the objective of investigating the effect of GCBE on mild obesity. METHODS: Male ddy mice were fed a standard diet containing GCBE and its principal constituents, namely, caffeine and chlorogenic acid, for 14 days. Further, hepatic triglyceride (TG) level was also investigated after consecutive administration (13 days) of GCBE and its constituents. To examine the effect of GCBE and its constituents on fat absorption, serum TG changes were evaluated in olive oil-loaded mice. In addition, to investigate the effect on hepatic TG metabolism, carnitine palmitoyltransferase (CPT) activity in mice was evaluated after consecutive ingestion (6 days) of GCBE and its constituents (caffeine, chlorogenic acid, neochlorogenic acid and feruloylquinic acid mixture). RESULTS: It was found that 0.5% and 1% GCBE reduced visceral fat content and body weight. Caffeine and chlorogenic acid showed a tendency to reduce visceral fat and body weight. Oral administration of GCBE (100 and 200 mg/kg.day) for 13 days showed a tendency to reduce hepatic TG in mice. In the same model, chlorogenic acid (60 mg/kg.day) reduced hepatic TG level. In mice loaded with olive oil (5 mL/kg), GCBE (200 and 400 mg/kg) and caffeine (20 and 40 mg/kg) reduced serum TG level. GCBE (1%), neochlorogenic acid (0.028% and 0.055%) and feruloylquinic acid mixture (0.081%) significantly enhanced hepatic CPT activity in mice. However, neither caffeine nor chlorogenic acid alone was found to enhance CPT activity. CONCLUSION: These results suggest that GCBE is possibly effective against weight gain and fat accumulation by inhibition of fat absorption and activation of fat metabolism in the liver. Caffeine was found to be a suppressor of fat absorption, while chlorogenic acid was found to be partially involved in the suppressive effect of GCBE that resulted in the reduction of hepatic TG level. Phenolic compounds such as neochlorogenic acid and feruloylquinic acid mixture, except chlorogenic acid, can enhance hepatic CPT activity.
