Green Coffee Beans Can Produce Substantial Weight Loss In Short Amount Of Time

a women who lost weightScientists today reported striking new evidence that green, or unroasted, coffee beans can produce a substantial decrease in body weight in a relatively short period of time. In a study presented at the 243rd National Meeting & Exposition of the American Chemical Society (ACS), the world’s largest scientific society, Joe Vinson, Ph.D., and colleagues described how a group of overweight or obese people who consumed a fraction of an ounce of ground green coffee beans each day lost about 10 percent of their body weight.

“Based on our results, taking multiple capsules of green coffee extract a day — while eating a low-fat, healthful diet and exercising regularly — appears to be a safe, effective, inexpensive way to lose weight,” Vinson said at the ACS meeting, being held here this week. He is with the University of Scranton in Pennsylvania.

The study involved 16 overweight or obese people aged 22-26 years who took capsules of the extract or capsules containing a placebo, an inactive powder, for a total of 22 weeks. The subjects alternated between a low dose and a higher dose of the extract. The low dose consisted of 700 mg of the coffee extract, and the high dose was 1,050 mg. It was a so-called “cross-over” study in which people cycled through the two doses and the placebo, each for six weeks. Such studies have advantages because each person serves as his or her own “control,” improving the chances of getting an accurate result.

All of the participants were monitored for their overall diet (calories, food eaten, etc.) and exercise over the study period. “Their calories, carbohydrates, fats and protein intake did not change during the study, nor did their exercise regimen change,” Vinson said.

In this video, Joe Vinson, Ph.D., from University of Scranton reported striking new evidence that green, or unroasted, coffee beans can produce a substantial decrease in body weight in a relatively short period of time.

Participants lost an average of 17 pounds during the 22 weeks of the study. It included an average of a 10.5 percent decrease in overall body weight and a 16 percent decrease in body fat. Vinson noted that weight loss might have been significantly faster, except that participants received the placebo and the lower dose of green coffee extract for part of the study period.

Vinson pointed out that previous studies have shown weight loss with green coffee. But this was the first to use higher amounts of the coffee extract and the first to measure the response to various doses. Based on those studies, Vinson believes that green coffee beans’ effects likely are due to a substance called chlorogenic acid that is present in unroasted coffee beans. Chlorogenic acid breaks down when coffee beans are roasted (usually at a temperature of 464-482 degrees Fahrenheit). Roasting gives coffee beans their distinctive color, aroma and flavor. Green coffee beans, in contrast, have little aroma and a slightly bitter taste.

    The one glaring thing missing from this post is whether the low or higher dose worked best – this info was not part of this press release. I will follow up and report back with what I find.

    By the way, I do not jump on the band wagon for weight loss pills – in fact, I never have once before… it is usually a bunch of hooey, but this looks to be a very interesting development. I plan to try out the green coffee been supplements. I’ll report back with progress or the lack thereof in my weight loss.

    I managed to locate a video of the original conference presentation. I added it to this article.

    The lead author states that they used the following green coffee extract supplement guidelines to achieve the impressive results reported in this study:

    1. 3 green coffee extract supplements per day
    2. 1050 MG/Day
    3. 1 supplement taken 30 minutes prior to each meal with lots of water (3 per day for a total of 1050 MG).

    I’ve come to know that most of the green coffee extract supplements on the market come in increments of 200MG or 400MG so most folks will not be able to take the exact amount used in the study.
