Garcinia cambogia is actually 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 solution for stomach bloating and gas. In India, additionally it is used as a treatment for rheumatism and bowel problems. The active ingredient is hydroxycitric acid (HCA). Although some data from animal studies claim that HCA may suppress appetite and the formation of fats and cholesterol within the liver, I’ve seen no evidence of its effectiveness for weight loss. A 2011 British report on nine studies figured that the use of dr oz cambogia garcinia reviews 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 led to weight reduction.
They recruited 86 overweight adults between the ages of 20 to 60 and checked their weight, levels of cholesterol and diet. They then divided the participants into three groups and randomly assigned those to take tablets containing two grams of either GCE or EGML, or a placebo containing two grams of starch. The study subjects continued making use of their regular diets and took the supplements for 10 weeks.
Results showed that neither supplement had any effect on the participants’ weight or triggered modifications in body mass index or waist-to-hip ratio, important risks for heart problems in overweight individuals. They reported that in the EGML group, HDL (“good”) cholesterol increased in comparison to those using the placebo. Apart from that, no significant changes in cholesterol or triglyceride levels were observed with either supplement.
The researchers noted that natural food supplements such as EGML have been thought to increase satiety, and, as a result can help reduce calorie intake. But in this research, they saw no effects on either satiety or calorie consumption. In reality, they reported increased calorie and cholesterol consumption in most three groups and suggested that the explanation may be that whenever participants were recruited they likely under-reported exactly how much they customarily ate.
You might see claims that Garcinia cambogia can promote weight reduction by increasing metabolism (the pace in which the body burns calories) and suppressing appetite, however the Korean investigators saw no evidence iejwom such effects. And I can tell you that this safest and best way to improve your metabolism is not really by way of a supplement or drug, however with regular exercise.
