For the past few years, viewers of Dr. Mehmet Oz's popular talk show regularly listen to him talk about what he terms "miracles." Translation: Diet supplements that can boost your weight loss. And now experts are warning that one of those miracles in particular, Garcinia cambogia, may not be all that he claimed, reported the Inquisitr on Jan. 17.
Garcinia cambogia is "the newest, fastest fat buster," proclaimed Dr. Oz on his show.
How it works: The natural extract of the plant, hydroxycitric acid (HCA), reportedly blocks your appetite. Some experts say that it can boost your weight loss. One study revealed that those taking it lost four pounds a month.
However, the evidence for the studies may not be as compelling as promised. Some critics are now saying that it's a scam, while others warn that it could be dangerous, with high doses resulting in toxicity.
Because Garcinia cambogia may lower a person’s blood sugar, it can interact with diabetes treatments. It also could cause problems for pregnant women, women who are breastfeeding, and people with dementia, said Catherine Ulbricht, senior pharmacist at Massachusetts General Hospital in Boston and co-founder of Natural Standard Research Collaboration, which reviews evidence on herbs and supplements.
However, in its favor, “some studies have shown that HCA stops an enzyme that turns sugar into fat,” added Catherine.
Look for a product that contains HCA and has no fillers, and talk with your doctor before trying it. Examples of products with HCA include NatureWise Garcinia Cambogia, 500 mg, Natural Appetite Suppressant and Weight Loss Supplement, 180 Vegetarian Capsules (click for details) and Pure Garcinia Cambogia Advanced Slimming Formula - Weight Loss Fat Burner Supplement - 60% HCA Extract (click for details).
What about related products? Dr. Oz also has discussed green coffee bean extract as another weight loss "miracle." The product contains chlorogenic acid.
Dr. Oz says: "Various studies have suggested that chlorogenic acid slows absorption of fat from food intake and also activates metabolism of extra fat." In studies, dieters lost a pound a week using the supplement without changing their diet.
If you look for a green coffee bean supplement, it should contain the chlorogenic acid extract, which can be listed as any of the following:
- GCA® (green coffee antioxidant): Example - NatureWise Green Coffee Bean Extract 800 with GCA Natural Weight Loss Supplement (click for details).
- Svetol®: Example - Genesis Today Green Coffee Bean with Svetol, 800 mg per Capsule (Click for details).
In addition, Dr. Oz suggests seeking a capsule that contains at least 45% chlorogenic acid. If you are going to take green coffee bean, the recommended dosage is 400 mg, three times a day – 30 minutes before each meal. However, some clinical trials have also demonstrated success with 200 mg.
He also talked about yacon syrup, which has been shown to result in more than a pound a week of fat loss without making any other changes. You can get the full details, including how to use and where to find it, by clicking here.
