For a number of years, green tea was extremely popular for its weight loss properties and continues to garner a lot of respect from dieters as well as health aficionados. However, a recent entrant in the world of slimming-aids is slowly taking control and dominance over green tea as a strong contender for weight loss, which is none other than green coffee bean extracts. In order to weigh in the evidence and discover which ‘green’ is the best.
Let’s look at some of the research studies conducted across the world.
Green coffee evidence:
A study conducted in January 2012, as reported by Dr Oz on his television show, it was seen that 16 participants who were examined over a period of 22 weeks were divided into three groups of high dosage green coffee bean extracts, mid-level dosage of green coffee bean extracts and a placebo. At the end of the study it was seen that individuals who consumed green coffee beans extracts on an average of 900 mg revealed a dramatic loss of over 9 kg weight per person.

In addition, none of these individuals reported any negative outcomes or side effects from the dosages. None of the studies involving weight loss supplements have revealed such astounding weight loss from any participant group.
Green tea evidence:
A study involving 38 Japanese men revealed that those who consumed green tea extracts for over 10 weeks experienced moderate amount of weight loss against the group that did not consume green tea. Although green tea is known to contribute to weight loss in both human and animal studies, it does so by increasing thermogenesis in the body that requires the body to expend more energy.
Although the amount of evidence in favour of green tea resulting in substantial weight loss is yet to evolve, some studies revealed that green tea extracts are highly beneficial in helping to maintain constant weight after weight loss takes place.
The amount of research and analysis done on green tea and the health benefits it has on an individual is slightly more than the limited studies done so far on Green coffee beans, but on the other hand, the evidence for weight loss with green coffee beans extracts is slightly higher than green tea. Green tea offers a number of health benefits but its effects are seen much slower than the impact green coffee bean extracts has on an individual.
Green tea naturally contains caffeine and hence large amounts of green tea supplements or beverage can cause a number of side effects such as anaemia, anxiety disorders, heartburn, convulsions and headaches. On the other hand green coffee bean extracts are prepared from decaffeinated coffee beans and only contain chlorogenic acid, which is the main component for overall health as well as weight loss.
It is seen that serious toxicity takes place in the consumption of green tea even in lower dosage and hence further study is needed to understand the effects of green tea in an individual. On the other hand studies conducted on Green coffee bean extracts, show that individuals who experienced weight loss even with high dosages of green coffee bean extracts did not experience any negative outcomes nor did they suffer side effects.
In the comparison study between green coffee bean supplements and green tea, it is safe to assume that extracts from green coffee beans are safer than green tea, although studies on both supplements and its compounds continue to take place around the world.
