Green coffee extract aids weight loss

Green coffee extract aids weight loss

Tuesday, March 27, 2012. At the 243rd National Meeting & Exposition of the American Chemical Society held in San Diego this week, Joe Vinson, PhD of the University of Scranton in Pennsylvania reported the finding of significant weight loss following supplementation with green coffee bean extract. Green (unroasted) coffee beans lack aroma and flavor, yet they have higher levels of a compound known as chlorogenic acid that has been found to have effects that include a reduction in post-meal glucose levels. While green coffee has been previously shown to benefit weight loss, the study is the first to use higher amounts of the extract and to evaluate the response to varying doses.

The current crossover study included 16 overweight men and women who received 700 milligrams green coffee extract, 1,050 milligrams green coffee extract or a placebo daily for six weeks, followed by two six-week periods during which the participants received one of the regimens not previously received. Each treatment phase was separated by a two week washout period. The subjects' dietary intake and exercise levels were monitored, and their weight regularly assessed. "Their calories, carbohydrates, fats and protein intake did not change during the study, nor did their exercise regimen change," Dr Vinson noted.

Weight loss averaged 17 pounds, including an average 16 percent decrease in body fat percentage and a 10.5 decrease in body weight, by the end of the study. No side effects were observed. Dr Vinson speculated that weight loss would have been more rapid were it not for the placebo and low dose of green coffee extract received by the participants, rather than continuous treatment with the higher dose. He believes that the weight-reducing component of green coffee resides in its chlorogenic acid content.

"Based on our results, taking multiple capsules of green coffee extract a day — while eating a low-fat, healthful diet and exercising regularly — appears to be a safe, effective, inexpensive way to lose weight," he concluded.

Supplementing with calcium and vitamin D results in decreased abdominal fat

What's Hot

The results of two double-blinded, placebo-controlled trials described online on December 14, 2011 in the American Journal of Clinical Nutrition conclude a beneficial effect for calcium and vitamin D in reducing visceral adipose tissue—fat that accumulates in the abdomen which is associated with several metabolic disorders.

A team from Massachusetts General Hospital randomized 88 overweight or obese men and women to receive a glass of orange juice fortified with 350 milligrams calcium and 100 international units vitamin D3, or nonfortified orange juice three times daily for 16 weeks. A separate trial of 83 men and women evaluated the effects of calcium and vitamin D-fortified "lite" orange juice, which has fewer calories than regular orange juice. Physical examinations conducted at the beginning of the study and at four week intervals ascertained weight and waist circumference. Computed tomography (CT) examination of the abdomen assessed visceral and subcutaneous fat tissue before and after treatment.

While changes in body weight, body mass index and waist circumference did not differ significantly between those who received fortified and nonfortified juice in either trial, the reduction in visceral adipose tissue was significantly greater among those that received fortified beverages. For those who received regular orange juice, the reduction averaged 12.7 cm2 in comparison with a loss of 1.3 cm2 in the control group, and in the lite orange juice group, the addition of calcium and vitamin D resulted in a 13.1 cm2 reduction in visceral adipose tissue compared to 6.4 cm2 in the control group.

"The data underscore the possible role of these two nutrients in fat metabolism and support a potential role of calcium and vitamin D in the preferential and beneficial reduction of visceral abdominal tissue," the authors conclude.

A wealth of published studies indicates that cranberry polyphenols may help to support a healthy urinary tract. In a significant advance, Life Extension has identified a unique compound available overseas but little-known in the United States that provides a complement to the whole cranberry's phytonutrient profile.

UTIRose™ is derived from Hibiscus sabdariffa, a species native to Europe, Asia, and Africa. Scientific analysis has shown that this species' flower and calyx (the green floral envelope surrounding the blossom) are rich in active polyphenols, including flavonoids, sambubiosides, and proanthocyanidins.
