Adult weight gain and obesity have become worldwide problems. Issues of cost and potential side effects of prescription weight loss drugs have led overweight and obese adults to try nutraceuticals that may aid weight loss. One promising nutraceutical provided by Applied Food Sciences, Inc. out of Austin, TX is green coffee bean extract, or GCA®, which contains high concentrations of chlorogenic acids that are known to have health benefits and to influence glucose and fat metabolism.

The World Health Organization predicts there will be 2.3 billion overweight adults in the world by 2015, and more than 700 million of them will be obese.
Worldwide obesity has more than doubled since 1980. In 2008, 1.5 billion adults, 20 years of age and older, were overweight (World Health Organization (WHO)...Geneva: WHO; 2011).
With the high cost of prescription weight loss drugs and the fear of side effects, the general public is turning to nutraceuticals. One promising nutraceutical provided by Applied Food Sciences, Inc. out of Austin, TX is green coffee extract, which contains high concentrations of chlorogenic acids that are known to have health benefits and to influence glucose and fat metabolism.
A 22-week crossover study was conducted to examine the efficacy and safety of a commercial green coffee extract product GCA® at reducing weight and body mass in 16 overweight adults. The green coffee extract utilized for this study was provided by Applied Food Sciences Inc (Austin, TX) under the trade name GCA®. This was a randomized, double-blind, 22-week study that implemented a crossover design to compare a low-dose green coffee extract, a high-dose green coffee extract, and a placebo. The results of the study were statistically significant reductions in weight, BMI, percent body fat, and heart rate after consuming GCA for two-thirds of the 22-week crossover study. All subjects completed the study and there were no side effects of using GCA.
Regarding nutrient intake, there were no significant changes in calories, percentage carbohydrates, percentage fat, or percentage proteins at any time during the study. In looking at the individual effects of the GCA; 16 of 16 lost weight, 16/16 had decreased percent body fat 16/16 had a reduction in BMI, 3/13 experienced a decrease in systolic blood pressure, and 5/16 a reduction in diastolic blood pressure. The results of the study are much more dramatic for weight loss and BMI than previous green coffee extract investigations.
The subjects averaged slightly over an 8 kg weight loss which was more than 10% of the body weight. For the study 10 of 16 subjects showed at least a 10% weight loss; five of the remaining six showed at least 5% weight loss; and the last individual showed a 4% weight loss. The most remarkable result was the fact that all 16 of the subjects were classified as overweight at the beginning of the study and at the end six of the subjects were now in the normal BMI category, ie, a normal weight for their height...Prevention and Newsweek.
