On one of The Dr Oz Show episodes, green coffee beans were recommended as a supplement to help with weight loss. Since then it has become a coveted health food among those looking to lose weight naturally.
Green coffee bean extract comes from non-roasted coffee beans and contains compounds known as chlorogenic acids. Because of this acid, it’s believed that the beans offer anti-oxidant effects which help to manage blood pressure as well as lose weight. While normal coffee beans contain them too, chlorogenic acids are usually removed when the beans are roasted, hence they are believed to be less effective in aiding weight loss.
Some of the weight loss effects associated with chrologenic acid include:
- Reducing fat stored in liver
- As it contains caffeine, it can boost metabolism
- It also decreases the absorption of carbohydrates, which inhibits weight gain
However, whether it works or not to help us lose weight, there is very scant evidence as many studies done only involve very few people. For instance, in a 2012 study, many were bewildered that subjects who had taken 1,050-mg and 700-mg doses managed to lose a whopping 16 pounds in six weeks compared to another group who was taking placebo doses. While it did make headlines, the study wasn’t widely accepted as it was only participated by 16 people and funded by a green coffee bean extract manufacturer. Later on, scientists evaluated three random clinical trials which totaled up to 142 subjects and concluded that using green coffee extract to lose weight offers only moderate results.
In a nutshell consuming the extract at moderate levels is relatively safe; and in combination with a healthy diet and exercise, it may help you to shed some pounds. However, it’s better to be cautious of taking too much of it – chlorogenic acid may increase the risk of heart disease as it raises the levels of the amino acid, homocysteine. To be on the safe side, take no more than 3 cups a day (300-400 mgs), and have it along with healthy foods.
