Women constitute most of Dr. Oz’s audience. The majority of women want to lose weight. Which is a match produced in heaven, a marketer’s dream. And Oz has never hesitated to exploit this fact to enhance audience share, playing fast and loose with sensationalized evidence rather than giving his viewers science-based advice.
Garcinia cambogia extract (GCE) comes from a tropical fruit from India and Southeast Asia. The active component, pure garcinia cambogia weight loss, is said to block fat and suppress hunger.
Garcinia cambogia extract (GCE) emanates from a tropical fruit from India and Southeast Asia. The active component, hydroxycitric acid (HCA), is claimed to bar fat and suppress hunger.
Dr. Oz has promoted a series of weight loss supplements on his show. Raspberry ketones were presented being a fat-busting miracle, then green coffee bean extract was touted as “magic,” “staggering,” and “unprecedented.” And today both of those miracles have apparently been superseded by a much greater miracle: Garcinia cambogia extract.
Dr. Oz calls it “The newest, fastest fat buster.” A technique for losing weight without “spending every waking moment exercising and dieting.” “Triples your weight loss.” “The most exciting breakthrough in natural weight reduction currently.” “The Holy Grail.” Oz claims that “Revolutionary new information says it might be the magic ingredient that lets you lose fat without diet or exercise.”
All that sounds too good to be true, in fact it is. Garcinia probably does work to some degree to improve weight reduction, although the evidence doesn’t begin to justify such grandiose claims.
Garcinia cambogia extract (GCE) comes from a tropical fruit grown in India and Southeast Asia. The active ingredient has become identified: hydroxycitric acid (HCA). It is known to block fat and suppress the appetite. It inhibits an important enzyme, citrate lyase, how the body demands to produce fat from carbohydrates. It suppresses appetite by increasing serotonin levels; low serotonin levels are related to depression and emotional or reactive eating.
It allegedly decreases belly fat, suppresses appetite, controls emotional eating, and changes body composition by increasing lean body mass. It doesn’t just produce weight-loss, nevertheless it improves all around health. It is known to decrease cholesterol, LDL, and triglycerides by 10-30% and also to raise levels of the “good cholesterol” HDL.
An impartial analysis discovered that some brands contain much less active ingredient than claimed. Consumers are encouraged to look for a minimum of 50% GCE with potassium though with no fillers, binders, or artificial ingredients.
It needs to be taken on empty stomach 30-60 minutes before dinner. Results increase with dosage, but doses over 3 000 mg each day needs to be cleared together with your doctor.
Dr. Oz recommends a dose of 500-1000 mg of natural pure garcinia cambogia before each meal. (Some experts believe the potassium salt is far more effective than other formulations.) He says never to take it when you are pregnant or breastfeeding, or in case you have Alzheimer’s disease or another forms of dementia, mainly because it can worsen dementia. For those who have diabetes, there may be hypoglycemia, and should you be with a statin, it may increase the chance of harmful negative effects like rhabdomyolysis or muscle degradation.
Oz contradicts himself: he suggests that it will produce weight-loss without diet or exercise, yet he clearly recommends it be employed along with exercise and effectively portioned meals.
With Dr. Oz’s history, I found myself not willing to merely accept his word for the wonders of Garcinia. I went along to PubMed, where a seek out hydroxycitric acid brought up 64 articles. Some were irrelevant, and the relevant ones included plenty of animal studies and a smaller number of human studies with inconsistent results.
Guinea pigs on the high cholesterol diet who are given a different Garcinia species (atriviridis) had a tendency to decrease lipid composition levels and fat deposition from the aorta. HCA caused congenital defects in rats. Another rat study found out that it decreased bodyweight gain and visceral fat accumulation by reduction of food consumption but had no lasting beneficial effects on hypertriglyceridemia and hyperinsulinemia. Another rat study revealed that it suppressed body fat accumulation but was toxic on the testes.
To try and sound right of your inconsistent results, Onakpoya et al. did a systematic report on the published randomized controlled trials (RCTs) at the time of 2011. Their analysis found a little, statistically significant difference in weight-loss (1.75 kg vs .88 kg, under 2 pounds). They commented that this studies all had methodological weaknesses, so these results could possibly be on account of GIGO (garbage in/garbage out). Both the studies with all the best methodology found 84dexcpky statistically significant difference from placebo. Adverse events were twice as common with Garcinia (headache, nausea, upper respiratory and gastrointestinal symptoms). The authors concluded:
Evidence from RCTs suggests that Garcinia extracts/HCA generate fat loss about the short-run. However, the magnitude of this effect is small, is no longer statistically significant when only rigorous RCTs are believed, and its clinical relevance seems questionable.
Oz featured an individual testimonial around the show coming from a woman who had lost ten pounds in 4 months. She started noticing results following a week; she reported that her sugar cravings were decreased, she had more energy, and she went down a gown size from 10 to 8. She had no adverse reactions. Says she was at the plateau and wanted a jump-start.
At this time, I don’t think we could reliably say whether pure garcinia cambogia weight loss includes a clinically relevant edge on simple calorie reduction and fitness. It seems to be safe, and it may have a role in assisting patients lose fat by assisting motivation and enlisting placebo effects.
Dr. Oz’s popularity is enduring, but diet fads aren’t. I confidently expect another “miracle” to supplant Garcinia within the Land of Oz from the not-too-distant future.
