Does Green Coffee Extract Have More Benefits Than a Cup of Joe?

Some people, including TV medical personality Dr. Mehmet Oz, says drinking green coffee extract provides more health benefits — particularly in terms of weight loss, than consuming a typical cup of coffee. Others contend the matter needs further studies.

The term "green coffee extract" refers to the raw or unroasted seeds of Coffea fruits, according to U.S. News. "In the typical roasting process of coffee beans, a chemical called chlorogenic acid is reduced. It's this chemical that is thought to be responsible for several health benefits including weight loss."

Chlorogenic acid is thought to block fat accumulation, boost weight loss, curb carbohydrate absorption and help regulate post-meal blood sugar levels, reports Shape. The resulting green coffee extract also does not taste or smell like coffee, a supposed benefit for those who don't enjoy java.

A research study presented in March 2012 at the national meeting of the American Chemical Society in San Diego showed that when 16 overweight and obese patients were given daily doses of green coffee extract in capsule form and instructed to maintain their usual dietary habits, they lost on average, 11 percent of their body weight over six months, reports.

The research caught the attention of Dr. Oz, who conducted his own study using 100 women in a two week period. The participants who took 400 milligrams of the coffee bean extract lost two pounds, on average, compared to one pound for the women who took the placebo.

Although several other small studies have been conducted, there are no conclusive scientific evidence that legitimizes the weight loss assertion, especially when referring to long-term success. Larger and longer trials are needed before any strong recommendations can be made. In addition, consumers need to also keep in mind the side effects of too much caffeine which may include headaches, insomnia and nervousness.
