Is the Newest, Fastest Fat Buster Revealed on Dr. Oz Show Supported by Studies?

“How can I burn fat without spending every waking moment exercising and diet?...Well, thanks to brand new scientific research, I can tell you about a revolutionary fat buster that you are hearing about here first,” promises Dr. Oz as he tells viewers that in response to questions from viewers and friends for the latest information on fat busters, he has discovered a new fat buster backed by scientific studies that will work wonders for losing weight.

With special guest Dr. Julie Chen, the new fat buster Dr. Oz discusses with viewers is a supplement that both suppresses appetite and prevents the formation of fat. This fat buster is called “Garcinia Cambogia,” but is also known under the name “Malabar tamarind” or its active component chemical name, “hydroxycitric acid (HCA )”. The active component HCA is isolated from the rind of the fruit and has been used for centuries in Ayurvedic medicine in India.

Garcinia Cambogia is described as a small, pumpkin-shaped fruit that is native to Indonesia, but can be found in West and Central Africa, Southeast Asia and India. Due to its known abilities among locals to suppress appetite, it has been utilized for many years in ethic dishes such as before-meal soups to aid in weight loss.

Today, extracts of Garcina Cambogia can be found in a convenient capsule form that has been scrutinized in multiple studies by a wide range of laboratories. A review of existing published literature shows both positive and negative reviews of the fat buster as a weight loss supplement; however, the consensus appears to support the view that Garcinia Cambogia can result in successful weight loss in some dieters—bur generally with results that are especially significant when in combination with a dieting and exercise program rather than by taking the supplement alone.

“How much weight would an average woman expect to lose if she uses this [Garcinia Cambogia supplement] for a month for example?” Dr. Oz asks Dr. Chen who practices integrative medicine and supports the use of Garcinia Cambogia for losing weight.

“On average, about four pounds…but, I always recommend diet and exercise with it, so if people take the supplements with it, they actually will lose 2-3 times what they would normally would lose with just diet and exercise alone,” says Dr. Chen.

Dr. Chen explains that Garcinia Cambogia is not only great for losing weight by suppressing appetite and blocking fat production, but that it also works well for people who are emotional eaters because it helps them sleep and feel more rested . Furthermore, it also results in helping to manage stress hormones such as cortisol that are a major culprit in the buildup of belly fat.

Dr. Oz and Dr. Chen provide more information about how Garcinia Cambogia works by discussing how that the active ingredient HCA chemically blocks a key enzyme called citrate lyase that is responsible for turning carbohydrates and other sugars into fat that is then stored by the body. One of the other benefits of blocking fat production this way is that it also results in a decrease in the levels of bad cholesterol (LDL) and triglycerides.

Garcinia Cambogia’s appetite-suppressing abilities are involved with increasing the levels of a brain neurotransmitter called “serotonin.” When low levels of serotonin are present—such as during stress or depression—emotional eating and increased calorie intake can result. However, when serotonin levels are increased via HCA, the drive toward reactive eating is decreased and the body winds up burning more fat.

Of the research claimed to support Garcinia Cambogia’s ability as a fat burner, mention is made of one randomized placebo-controlled study that followed 60 obese individuals for 8 weeks. By the end of the 8-week study, the HCA group lost an average of 14 pounds in comparison to the average 6 pounds lost by the placebo group. It should be noted that both groups were on a rather restrictive 1,200 calorie per day diet; however, the HCA group did lose twice as much weight and reported not feeling quite as hungry as the placebo group.

The study also showed that total cholesterol, LDL, triglycerides and serum leptin levels were significantly reduced, while HDL (good cholesterol), serotonin levels, and excretion of urinary fat metabolites (biomarkers of fat burning) were significantly increased--all indications supporting its fat busting claims on The Dr. Oz Show.

With the exception of one study published in the past that found evidence of suspected testicular toxicity in rats given large doses of HCA—and has since been discounted by follow-up studies—eating Garcinia Cambogia supplements have been shown repeatedly in multiple studies to be safe.

However, Dr. Oz and Dr. Chen advise viewers not to take this supplement if pregnant or breastfeeding, and that you should talk to your doctor about it if you are a diabetic. Other sources state that taking HCA with statins may cause harmful side effects such as muscle tissue damage and that people with Alzheimer’s or other types of dementia should avoid the supplement because it may worsen their condition.

Dr. Oz’s recommendations when looking for a Garcinia Cambogia supplement are to:

• Avoid Garcinia Cambogia supplements with fillers or artificial ingredients

• Look on the label for the words “Garcinia Cambogia” or “GCE” with at least 50% HCA (active ingredient potassium).

• Take 500-1000 mg 30-60 minutes before each meal, and no more than 3000 mg total per day.
