Green coffee bean extract comes from coffee beans (Many people claim that taking green coffee bean extract can help with weight loss.) that haven’t been roasted.
Coffee beans contain compounds known as chlorogenic acids.
These compounds are believed to have antioxidant activities, help lower blood pressure, and help you lose weight.
When coffee is roasted, its chlorogenic acid content is greatly reduced.
This is why drinking coffee is not thought to have the same weight-loss effects produced by the unroasted beans.
Chlorogenic acids haven’t been widely studied as a weight loss supplement for people. This study shows that green coffee extract may have the potential to help with weight loss.
How Does Green Coffee Bean Extract Work… What is The Mechanism?
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.
The research so far tends to say that chlorogenic acid (an extract in green coffee bean) disrupts an enzyme called glucose-6-phosphatase, which is involved in how the body used glucose (sugar).
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.
Negative side effects for green coffee extract haven’t been reported
