What is garcinia cambogia?
Today’s market is full of “miracle drugs” and supplements that claim to help you drop pounds fast. It’s no wonder they fly off the shelves and into medicine cabinets across the country. TV personality Dr. Oz and others like him have showered praise on one of these products in particular: the controversial garcinia cambogia fruit.
Garcinia cambogia is a citrus fruit that grows in Southeast Asia. An extract from the fruit’s rind, hydroxycitric acid (HCA), has historically been used for cooking, but it has also been used for weight loss. You can buy garcinia cambogia online or at most health and supplement stores. It comes in pill form or as a powder. Let’s look at what, if anything, garcinia cambogia can do for your weight.
Health claims: Fact or fiction?
Advocates say that HCA, an organic acid, works by making you feel full, reducing your appetite, and affecting your metabolism. It’s this effect that has led many to herald it as a natural weight loss cure. Some say it may also help improve high cholesterol or enhance athletic performance.
The list of garcinia cambogia’s rumored benefits is a long one. It can be hard to determine the truth to the claims about its “miracle” properties. So, how do these health claims match up to scientific research?
1. Claim: Makes you feel full
Verdict: No evidence. An extensive review of the existing research on garcinia cambogia determined that there simply wasn’t conclusive evidence to suggest that the supplement or HCA had any effects on appetite and satiety. Although some rodent studies had positive results, no human studies could replicate them.
2. Claim: Lowers body weight
Verdict: No evidence. Existing evidence doesn’t prove that garcinia cambogia alone can facilitate weight loss. A 12-week, randomized, double-blind, placebo-controlled study published in markethealth.com found that the supplement didn’t help with significant weight loss or decrease in fat mass. Both the control and garcinia group were placed on high-fiber, low-calorie diets.

3. Claim: Speeds metabolism
Verdict: Some evidence. There is some evidence that supplementing with garcinia cambogia can influence fat metabolism. Several studies have found that both mice and humans experience an increase in fat metabolism after supplementing with HCA.
4. Claim: Enhances athletic performance
Verdict: Some evidence. Garcinia cambogia may increase the amount of time it takes to reach exhaustion during exercise, according to one study. Another study that used mice had similar results, showing that HCA enhanced endurance during running.
