New Study Shows, Green Coffee May Generate to Weight Loss

Is the secret to weight loss in all of our cupboards right now? A few recent studies say this may in fact be so, though it’s not in the form we’re most familiar with.  Coffee has been shown in numerous recent studies to not only provide weight loss, but to do so at a level unlike what has been seen with any other natural ingredients in the past.  Green coffee is the natural and unroasted version of what we use in our “morning cup of joe” but has been shown in clinical trials to be a tremendously effective weight loss treatment.  A recent study from the ACS (American Chemical Society) found that green coffee extract daily actually resulted in sustained and significant weight loss in users, even without changes in their diet.

The results from this study were, over a period of 22 weeks, that those taking green coffee extract (700mg twice per day) lost significantly more weight than the placebo group.  On average, a green coffee participate lost around 30 pounds over this period, while the placebo group lost around 3 pounds.  This study represents one of the first true attempts to quantify weight loss derived from these natural substances, and the results are quite good for users. Participants simply took their dosage of green coffee extract, and as a result saw these weight loss results. It’s typically thought to be necessary to take green coffee through a capsule such as this, as it is very bitter and difficult to take otherwise. Caffeine from these supplements are fairly low, about half a cup of coffee worth.

Green Coffee 800mgWhat was in Green Coffee That Caused These Effects?

The ingredient that was linked to these weight loss results is known as Chlorogenic acid.  This substance has been linked to weight loss for several decades, however, it’s only rarely bioavailable via regular foods we eat.  Green coffee is the exception to this, as the extract makes this substance extremely bioavailable for our body to use.  This compound has been shown to increase metabolism and decrease appetite, but only recently has it been shown that green coffee is the best way to take this.

On average in the study, participants lost 10.5% of their total body weight, with a 16% decrease in body fat.  This is a tremendous result, when users did not change their diet whatsoever.  It was thought that this level was less than the idealized case, because participants went on a placebo at points throughout the study.  Those users in the study actually ate an average of over 2400 calories per day, this clearly is far more than you’d expect someone to eat that’s losing weight so quickly.

Was There Any Patient Risk in the Study?

One of the more exciting results from this study was that those on green coffee GCA did not experience any side effects during the study.  Green coffee is a naturally occurring substance, so it’s clear that is likely has very limited risk to those taking it.  It’s really no different than drinking coffee, which we’ve been doing for thousands of years.  Participants did have a roughly 2 beat per minute decrease in their heart rate, which has both good and bad potential impacts.  Those on any prescription medicines will of course want to talk to their physician before going on any weight loss program, even this one.

This isn’t the only study which has demonstrated these positive results.  Another study from an Italian University found that in mice, green coffee extracts also caused significant reduction in weight gain and more favorable fat accumulation (less around hips/thighs and stomach).  Green coffee appears to block the uptake of fats we eat as well, at least in part.  These results are indeed promising, and demonstrate the potential power of GCA for those people struggling to lose weight.  Chrologenic acid is lost during the coffee roasting process for the most part, which is why these benefits are not found in roasted coffee.
