Green Coffee Extract ( GCE- Coffea canephora ) is mostly obtained from green or raw coffee. It has been reported to have anti oxidant potential. The purpose of Onakpya review et al was to assess the clinical efficacy of GCE as a weight loss supplement. After Dr Oz's show it became the most natural weight loss supplement of 2012. This is wrong ! Since then there are many other supplements for weight loss
The study mentioned above did use endpoint of mean changes in body weight. From this review it does indicate that GCE can promote weight loss. The magnitude of this weight loss was moderate but there were very few trials and limited small groups. I agree with the authors that larger trials are needed to assess the efficacy and safety of GCE especially if this is to be used on a long term basis. This is why I object to discussing this on a television broadcast. I am afraid that might be long term side effects which have not been studied and it is possibly not right for every overweight individual.
In 2007 Blum and others studied GCE ( Coffea canephora robusta Pierre) .The authors did conclude the green coffee extract can modulate glucose metabolism which may impact weight management. I did not put patients on this supplement at that time nor now, because the population studied was 18 men and women from Bangor, Maine. This is not a large patient population and jelly beans were used as the glucose load. An innovative approach which has much merit, but this does not mean I tell the world to use Green Coffee Extract
More studies need to be done on this
Until tomorrow
