What Are Green Coffee Beans?
Green Coffee beans are simply coffee beans that have not been roasted, hence the green appearance in their natural, raw state. When coffee beans are roasted, recognisable for the distinctive taste and colour for our daily cup of coffee, they lose a naturally occurring antioxidant-rich compound called chlorogenic acid (CGA).
Their effects were featured on the world famous Dr Oz TV show which highlighted these findings as it is believed by diet and health professionals that chlorogenic acid can significantly give a boost to weight loss, (some studies have shown up to double the weight lost when compared with dieters not taking any supplement) which is why green coffee beans are now found in so many weight loss products.
Drinking green coffee beans as a beverage would be very unappetising and is reported to have quite a bitter flavour, which is why green coffee extract is used in many supplements to help boost weight loss.
How Can Green Coffee Beans Aid Weight Loss?
This chlorogenic acid reduces the amount of glucose in the blood by using it as energy; the body then has to burn fat cells as energy by thermogenesis, which then leads to weight loss.
The chlorogenic acid slows down the process of the glucose entering the bloodstream reducing the fat absorption which then leads to weight loss. Studies have shown that chlorogenic acid can help the liver to break down the fat faster.
Green Coffe Extract – Svetol® can help increase fat burning
Green coffee bean extract could help to lower the levels of insulin which helps to improve metabolism and control weight maintenance, ideal for people who struggle to sustain their weight.
Additional Benefits Of Green Coffee Beans
The antioxidants in green coffee beans (GCB) act as a shield against environmental influences and harmful free radicals, even helping to prevent premature ageing.
The chlorogenic acid in green coffee extract can also help reduce hypertension (high blood pressure) and reduce the risk of heart conditions. Chlorogenic acid is also proven to help prevent type 2 diabetes which is often caused through being overweight and having high blood pressure.
It can have favourable effects on diseases such as Parkinson’s disease and helps to relieve inflammation.
What To Look For In A Good GCE?
There are a few recommended guidelines to look for when choosing a green coffee dietary supplement, the first thing to check is that the product contains either Svetol® or GCA, these are the only extracts that have been clinically proven to work. Also ensure that the concentration of Chlorogenic acid is at least 45% to be effective.
As for dosing, the recommended amount to take is at least 400mg 3 times a day.
Green Coffee Bean Extract is suitable for virtually all, there have been no side effects reported, however experts do suggest that if you are pregnant, breast feeding, or under 16 that you should seek medical advice before taking any form of green coffee in supplement form.

While progress has been made, the mechanism on glucose and lipid metabolism has not yet been conclusively elucidated. The side effects of CGA have not yet been investigated comprehensively. Further research is required to elucidate both the short- and long-term effects of CGA on glucose and lipid metabolism. It is hoped that research concerning the mechanism of action of CGA on glucose and lipid metabolism will be developed in the future, and that information on the potential clinical applications of CGA will increase.“

Five different procedures of purification were compared. The first consisted of a successive use of different organic solvents, the second was based on a filtration through a C18 cartridge, the third used two combined reagents, and the remaining two methods (4 and 5) were a simplification of the third. One of the two simplest methods of purification (method 4) was also the fastest, the most accurate, and the least biased. Consequently, this method could be used routinely to quantify chlorogenic acids in green coffee beans.“

Issues of cost and potential side effects of prescription weight loss drugs have led overweight and obese adults to try nutraceuticals that may aid weight loss. One promising nutraceutical is green coffee extract, which contains high concentrations of chlorogenic acids hat are known to have health benefits and to influence glucose and fat metabolism. A 22-week crossover study was conducted to examine the efficacy and safety of a commercial green coffee extract product GCA™ at reducing weight and body mass in 16 overweight adults. … The results are consistent with human and animal studies and a meta-analysis of the efficacy of green coffee extract in weight loss. The results suggest that GCA may be an effective nutraceutical in reducing weight in preobese adults, and may be an inexpensive means of preventing obesity in overweight adults.“
