How to lose fat’ is a very popular topic and one that is asked many times, but I could never find any supplements that had any solid scientific basis behind them to prove that they may actually work and help people lose fat. I recently noticed a supplement called ‘green coffee bean extract’ getting a lot of attention and becoming increasingly popular. People claiming ‘Great aid to weight loss’, ‘Excellent product’ and ‘Lost weight for holidays’ had me interested, and I was encouraged to look into the subject further to see if any studies were available proving green coffee bean supplements could actually help with weight control and losing fat. What I found was intriguing.
Green coffee bean extract contains high concentrations of ‘Chlorogenic acid’, a natural compound, which is known to have health benefits and to influence glucose and fat metabolism. It can also be found in peaches and prunes.
Caffeine Suppresses Fat Absorption?
Research undertaken in 2006 (Shimoda et al) revealed interesting results with mice as the subjects. The results showed that consumption of Green Coffee Bean Extract (aka, GCBE) for 14 days caused a suppressive effect on weight gain and visceral fat accumulation in the mice. GCBE used contained 10% caffeine and 27% chlorogenic acid as the principal constituents, and these constituents showed a tendency to suppress body weight gain and visceral fat accumulation. Thus, these constituents are suggested to be partially involved in the suppressive effect of GCBE on body weight gain and visceral fat accumulation.
The study conclusion announced ‘Caffeine suppresses fat absorption, while chlorogenic acid and its related compounds are found to be involved in the enhancement of fat metabolism in the liver’. So, a double body blow to fat.
With adult weight gain and obesity becoming a serious worldwide problem, many studies are now being undertaken to find ways of aiding weight loss. Research published in 2012 (Joe A Vinson et al) revealed a study using 16 overweight adults over a 22 week period ingesting a commercial green coffee bean extract. Significant reductions were observed in body weight, body mass index, and body fat percentage, as well as a small decrease in heart rate, but with no significant changes to diet over the course of the study. Body mass index for six subjects shifted from pre-obesity to the normal weight range.
The study concluded – ‘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 GCBE may be effective in reducing weight in pre-obese adults, and may be an inexpensive means of preventing obesity in overweight adults.’
Coffee is also of interest as a possible food supplement for weight loss because caffeine is a well-known stimulant, and a study found (Lopez-Garcia et al) that coffee consumption resulted in less weight gain in obese men over an 18-month period. Several investigations have also found that coffee consumption reduces the risk of type 2 diabetes, and one of the mechanisms proposed for this benefit is that coffee consumption is inversely associated with weight gain (Greenberg JA et al).
The evidence suggests that the intake of green coffee bean extract can promote weight loss and also prevent the accumulation of body fat. The main ingredient ‘Chlorogenic acid’, indicates this as the most important constituent in GCBE with the assistance of caffeine.
