Garcinia cambogia is a small, sour, purple fruit indigenous 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, it is also used as being a treatment for rheumatism and bowel problems. The active ingredient is hydroxycitric acid (HCA). Although some data from animal studies suggest that HCA may suppress appetite and also the formation of fats and cholesterol in the liver, I’ve seen no proof of its usefulness for weight loss. A 2011 British report on 9 studies concluded that the use of dr oz holy grail weight loss can lead to 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 even a placebo containing two grams of starch. The research subjects continued using their regular diets and took the supplements for 10 weeks.
Results showed that neither supplement had any effect on the participants’ weight or resulted in alterations in bmi or waist-to-hip ratio, important risks for heart disease in overweight individuals. They reported that within the EGML group, HDL (“good”) cholesterol increased when compared with those taking the placebo. Apart from that, no significant modifications in cholesterol or triglyceride levels were observed with either supplement.
They noted that natural food supplements including EGML happen to be believed to increase satiety, and, consequently may help reduce calorie consumption. Nevertheless in this study, they saw no effects on either satiety or calorie intake. In reality, they reported increased calorie and cholesterol consumption in most three groups and suggested that this explanation may be that when participants were recruited they likely under-reported just how much they customarily ate.
You may see claims that Garcinia cambogia can promote weight-loss by increasing metabolism (the rate at which your body burns calories) and suppressing appetite, nevertheless the Korean investigators saw no evidence iejwom such effects. And I can tell you that the safest and best approach to improve your metabolism will not be through a supplement or drug, but with regular exercise.
