Garcinia cambogia is a small, sour, purple fruit native to India and Southeast Asia. Its rind has traditionally been used as a food preservative, flavoring agent and as remedy for stomach bloating and gas. In India, additionally it is used as a treatment for rheumatism and bowel problems. The active component is hydroxycitric acid (HCA). Although some data from animal studies claim that HCA may suppress appetite and also the formation of fats and cholesterol within the liver, I’ve seen no proof of its effectiveness for weight loss. A 2011 British review of nine studies concluded that the use of garcinia cambogia dr oz review can result in short-term weight-loss, but a newer human trial from Korea that compared the effects of GCE and another supplement, EGML, an extract of the leaves of Glycine max (soybean), found that neither resulted in weight loss.
They recruited 86 overweight adults between the ages of 20 to 60 and checked how much they weigh, cholesterol and diet. Then they divided the participants into three groups and randomly assigned those to take tablets containing two grams of either GCE or EGML, or even a placebo containing two grams of starch. The research subjects continued making use of their regular diets and took the supplements for 10 weeks.
Results indicated that neither supplement had any effect on the participants’ weight or resulted in modifications in body mass index or waist-to-hip ratio, important risk factors for cardiovascular disease in overweight individuals. The researchers reported that in the EGML group, HDL (“good”) cholesterol increased in comparison to those utilizing the placebo. Besides that, no significant changes in cholesterol or triglyceride levels were observed with either supplement.
They noted that natural food supplements such as EGML have been thought to increase satiety, and, because of this may help reduce calorie intake. But in this research, they saw no effects on either satiety or calorie intake. In fact, they reported increased calorie and cholesterol consumption in all three groups and suggested that the explanation could be that when participants were recruited they likely under-reported how much they customarily ate.
You could see claims that Garcinia cambogia can promote weight loss by increasing metabolism (the pace in which your system burns calories) and suppressing appetite, however the Korean investigators saw no evidence iejwom such effects. And I will tell you that the safest and best approach to improve your metabolism is not by way of a supplement or drug, however with regular exercise.
