Doubts arise about the weight loss effect of green coffee bean extract


Another Dr. Oz Show topic makes it to “The Whistle Blog” written by Diane Kress, RD CDE  registered dietitian, certified diabetes educator, owner and director of her private practice.  She also has over 30 years experience specializing in metabolic syndrome, pre diabetes, type 2 diabetes, and weight reduction.

Now, she writes about the much promoted dietary supplement  –  “miracle pill” or  “magic pill” as called on the TV –  green coffee been extract.

“Let’s talk reality about this amazing discovery,” Diane writes before explaining that green coffee beans are just coffee beans before they are roasted. She continues: “Green coffee beans are a very good source of chlorogenic acid, which is one of the most abundant polyphenols and antioxidants in the human diet. Major food sources include coffee, blueberries, grapes, apples, sunflower seeds, broccoli, spinach, lettuce, Chinese parsley, eggplant.”

Back in May, the wrote few articles about the freshly discovered weight loss powers of the green coffee bean extract. Many readers expresses serious interest and the topic still remains hot:

However, Diane Kress now brings up a new detail, which was unknown until this moment: “The “Staggering Study” about the green coffee bean extract was funded by Applied Food Sciences, which makes the green coffee antioxidant supplement.”

Then the dietitian goes on on questioning the length and the subjects of the research, quoting the head of the study, only to conclude:

“There does not appear to be any strong evidence that taking green coffee bean extract. Dr. Oz’s guest recommends 800mg twice a day (nice income for Applied Food Sciences, the company who funded this study). I’ve read that caution should be used in consuming green coffee bean extracts as they may contain high levels of caffeine as well.
I’ve also read some information about a 2006 study in which green coffee bean extract in a very low dose (140 mg) administered to hypertensive subjects resulted in a significant reduction in both systolic and diastolic blood pressure levels, without any observed side effects. Dr. Oz’s guest presenter recommended 1600mg/day.
When the dust settles and all is said and done, green coffee extract may be a great antioxidant like the antioxidants in many other fruits and vegetables. Does there appear to be any reason to start using it regularly at this point? No.”
