if you are aware of weight loss supplements, you would sure have heard about Garcinia Cambogia.
It is the most popular weight loss supplement available in market today in US.
Garcinia cambogia or garcinia gummi gutta is a tropical fruit that looks similar to a pumpkin.
It is native to Southeast Asian countries and India.
This supplement is apparently said to triple one’s weight loss outcome.
The active ingredient present in it is hydroxycitric acid also called HCA. This component is said to inhibit the activity of an enzyme involved in fat metabolism called citrate lyase.
It is shown to suppress appetite and block production of fat. Most of the studies conducted in relation to Garcinia cambogia and weight loss are on rat models.
However seeing the hype and raging fame of this supplement in the world of obesity, a clinical trial was conducted to evaluate its effectiveness.
What happened in the study?
In the trial, subjects were randomly assigned to groups where one group received 1500mg of hydroxycitric acid and the other group received placebo.
Duration of the study was 12 weeks. All subjects were given a diet low on energy and high on fibre. Body weight and fat mass were evaluated on a weekly basis.

What was the outcome?
Subjects in both the groups lost significant amount of weight, however difference among outcomes of both groups was not significant. Also the treatment group did not show much significant loss of body fat.
How did this occur?
Hydroxycitric acid brings about weight loss through following mechanisms:
- By regulating chemical named serotonin that is involved in stimulating appetite
- Increasing fat oxidation
- Preventing formation of fat
- Reducing the activity of obesity related genes
However the effect of HCA was not strong enough to produce better results than placebo.
What does this mean?
Since both the groups had to follow dietary restrictions and not much difference in weight was observed, the resultant weight loss could not be attributed to Garcinia cambogia.
So Garcinia cambogia does aid in weight loss but the outcome is not significant enough when compared with the action of energy restricted diet alone.
A mixed review is available for this supplement; however scientific evidence regarding the same is poor. Garcinia cambogia appears to be safe.
One is free to try it; however we would say that there are more effective options available. Eat healthy. Exercise wisely.
