What Is Green Coffee Bean Extract & How IT Works?

February 01, 2017

Losing weight can be incredibly difficult.

For this reason, people have turned to all sorts of supplements in order to make things easier.

Green Coffee Bean Extract is one of them…. it is currently among the world’s most popular weight loss supplements.

As the name implies, this supplement is extracted from green coffee beans.

It contains a substance called Chlorogenic Acid, which is believed to be responsible for the weight loss effects.

Green coffee extract was promoted by Dr. Oz back in 2012. He is an American TV doctor and probably the most famous health “guru” in the world.

I’m a big fan of supplements in general, but I am extra skeptical when it comes to weight loss supplements because they almost never work as advertised.

This article takes a detailed look at Green Coffee Bean Extract… what it is, how it works and what the science has to say about it.

What Are Green Coffee Beans?

Green coffee beans are basically just unroasted coffee beans.

This is what they look like:

Coffee beans are naturally green, but they are usually roasted before being sold to the consumer. This is the process that turns them brown.

As we know… coffee beans are loaded with antioxidants and pharmacologically active compounds. Two of the most important ones are Caffeine and Chlorogenic Acid.

Chlorogenic Acid is believed to be the main active ingredient in green coffee beans. That is, the substances that produces the weight loss effects.

Unfortunately…. most of the chlorogenic acid is removed when coffee is roasted.

For this reason, regular coffee beans won’t have the same effect (although there are plenty of other good reasons to drink coffee if you enjoy it).

How Does Green Coffee Bean Extract Work?

Green coffee bean extract does contain some caffeine.

Several studies have shown that caffeine can boost metabolism by up to 3-11%.

However, the main active ingredient is believed to be the chlorogenic acid.

Some human studies suggest that it can reduce the absorption of carbohydrates from the digestive tract, which lowers blood sugar and insulin spikes.

If this is true, then taking green coffee bean extract would be like eating a slightly lower carbohydrate diet.

Other studies (in mice and rats) have shown that chlorogenic acid can reduce body weight, reduce fat absorbed from the diet, reduce fat stored in the liver and improve the function of the fat burning hormone adiponectin.

Chlorogenic acid has also been shown to drastically improve cholestrol and triglyceride levels in rats. These are important risk factors for heart disease
