The collective excitement over green coffee bean extract as an effective weight loss supplement has surpassed fever pitch. In fact, you’ve probably heard claims and promises surrounding green coffee bean extract that range from the plausible, “speed-up weight loss” to the ridiculous, “miracle fat burner.”

So how well does green coffee bean extract actually work for weight loss? Here’s everything you need to know about this much vaunted fat burner.

What Is Green Coffee Bean Extract?

Put simply, green coffee consists of unroasted coffee beans. By harvesting beans before they’re roasted, this preserves the chlorogenic acid, which is where the major weight loss benefits associated with green coffee bean extract comes from.

Chlorogenic acid plays a role in decreasing caloric intake by inhibiting an enzyme that promotes formation of glucose in the liver. Thanks to this enzyme-inhibiting ability, chlorogenic acid is suggested to be at least partially responsible for reducing glycemic disorders such as diabetes.

What’s more, green coffee bean extract promotes healthy blood sugar levels and improves glucose metabolism.

What The Research Says

A study published in the journal Diabetes, Metabolic Syndrome and Obesity examined the effects of green coffee bean extracts on 16 overweight adults with a BMI greater than 25 for 12 weeks.

The subjects supplemented with either 700 or 1050 mg of cholorgenic acid per day. Results of the study revealed the subjects lost an average of 18 pounds, including 4.4% of their overall body fat. [1]

Another study used mice to research green coffee bean extract’s effects on fat accumulation and body weight. At the end of the 14 day study, researchers concluded green coffee bean extract effectively reduced visceral fat content and body weight.[2]
