Does green coffee bean extract work? A detailed review

More studies

Several other studies have reported significant weight loss in people taking green coffee bean extract (11).

However, it’s important to keep in mind that some of these studies were sponsored by companies that profit from sales of green coffee beans.

This doesn’t necessarily mean that the results are invalid, but it is known that the funding source of a study can have a significant effect on the outcome. For this reason, it is a good idea to be extra skeptical of industry funded research (12).

In 2011, a review of the evidence behind green coffee bean extract concluded (13):

«… the results from these trials are promising, but the studies are all of poor methodological quality. More rigorous trials are needed to assess the usefulness of GCE as a weight loss tool.»

Bottom Line: Several controlled trials in humans show that green coffee bean extract can lead to significant weight loss. However, these studies were relatively small and some of them were industry sponsored.

Take home message

Green coffee bean extract does appear to be useful as a weight loss aid. It may also have some benefits for glucose metabolism and blood pressure.

However… most of the studies are small, short-term and often sponsored by companies that produce or sell green coffee beans.

At the end of the day, the only thing that is proven to lead to long-term results is changing your diet.

In this regard, cutting carbs and eating more protein seem to be the most effective, as well as emphasizing real, unprocessed foods.

That being said… I suppose green coffee bean extract is worth trying out if you are curious about it.

It might have a mild effect that can last for a few weeks or months, but I wouldn’t expect anything beyond that.

Losing weight is a marathon, not a sprint… and quick fixes never work in the long-term.

If you would like to purchase green coffee bean extract, it can be found in health food stores and online.
