Since Dr. Oz first featured it on his television show back in 2012, people across the country have been asking the same question – does Green Coffee Bean Extract work? The best way to form an opinion about the efficacy of this powerful product is to take a look at a few trials and studies that have been conducted over the years.
How the Studies Work
First and foremost, in answering the question “does Green Coffee Bean Extract work?” it is important to keep in mind that there have been no large-scale clinical trials to date. However, there have been several small-scale studies designed to help determine the efficacy and the safety of this product. Overall, the results are favorable, and when combined with individual user experiences that praise the product, it seems to be effective for weight loss.
Green Coffee Bean Extract Study to Determine Efficacy
In one small-scale study, 30 overweight patients were divided into two groups in a randomized, controlled trial. The first group was given regular instant coffee once per day, and the second group was given instant coffee fortified with 200mg of Green Coffee Bean Extract once per day. Neither group changed their diet or exercise habits, and they were closely monitored for compliance. Those using just instant coffee lost an average of 3.7 pounds and 0.7% of their body fat in 12 weeks. Conversely, those using instant coffee fortified with Green Coffee Bean Extract lost an average of 11.0 pounds and 3.6% of their body fat in the same timeframe.
A Study on Safety
Another study was conducted primarily to test the safety of GCA (chlorogenic acid), which is the main ingredient in Green Coffee Bean Extract. Sixteen overweight adults participated in a 22-week crossover study. One-third received a high dose of GCA (1050mg), one-third received a low dose (700mg), and one-third received a placebo. At the end of the study, significant reductions in body weight, body mass index, and body fat percentages directly correlated to the patients who had used GCA, with those using the high dose losing the most weight. It is expected that further clinical trials like this one will continue to help answer the question “does Green Coffee Bean Extract work?”
Another Obesity Study
Some very early research exists that also helps back the efficacy of Green Coffee Bean Extract when provided to obese patients. Patients took Green Coffee Bean Extract for a period ranging from eight to 12 weeks at very high doses – five times per day. These patients lost between 2.5kg and 3.7kg more than people taking a placebo in that same time frame. This study also helps show that Green Coffee Bean Extract shows unique potential when it comes to weight loss and burning body fat.
Does Green Coffee Bean Extract work? It would seem that it certainly does – even if people do not change their diets or lifestyles. However, those who want to experience the best possible results should switch to a healthier diet and a regular workout routine in order to maximize their own weight loss.
