Scientists have found new evidence that green, or unroasted, coffee beans can produce a substantial decrease in body weight in a relatively short period of time.
Researcher Joe Vinson, who is with the University of Scranton in Pennsylvania, and colleagues described how a group of overweight or obese people who consumed a fraction of an ounce of ground green coffee beans each day lost about 10 percent of their body weight.
Researcher Joe Vinson, who is with the University of Scranton in Pennsylvania, and colleagues described how a group of overweight or obese people who consumed a fraction of an ounce of ground green coffee beans each day lost about 10 percent of their body weight.
“Based on our results, taking multiple capsules of green coffee extract a day — while eating a low-fat, healthy diet and exercising regularly — appears to be a safe, effective, inexpensive way to lose weight,” Vinson said.
The study involved 16 overweight or obese people aged 22-26 years who took capsules of the extract or capsules containing a placebo, an inactive powder, for a total of 22 weeks.
The subjects alternated between a low dose and a higher dose of the extract. The low dose consisted of 700 mg of the coffee extract, and the high dose was 1,050 mg.
It was a so-called “cross-over” study in which people cycled through the two doses and the placebo, each for six weeks. Such studies have advantages because each person serves as his or her own “control,” improving the chances of getting an accurate result.
Participants lost an average of 17 pounds during the 22 weeks of the study. It included an average of a 10.5 percent decrease in overall body weight and a 16 percent decrease in body fat.
Vinson noted that weight loss might have been significantly faster, except that participants received the placebo and the lower dose of green coffee extract for part of the study period.
Vinson pointed out that previous studies have shown weight loss with green coffee. But this was the first to use higher amounts of the coffee extract and the first to measure the response to various doses.
Based on those studies, Vinson believes that green coffee beans’ effects likely are due to a substance called chlorogenic acid that is present in unroasted coffee beans.
Chlorogenic acid breaks down when coffee beans are roasted (usually at a temperature of 464-482 degrees Fahrenheit). Roasting gives coffee beans their distinctive colour, aroma and flavour. Green coffee beans, in contrast, have little aroma and a slightly bitter taste.
Chocolate and wine helps lose weight
Chocolate lovers no longer have to fear the flab as eating more can help you keep slim. A study has found that despite boosting calorie intake, regular chocolate consumption is related to lower body mass index (BMI).
The good news about chocolate emerged after scientists screened a group of 972 men and women with an average age of 57 for a study of statins – cholesterol-lowering drugs. Among other diet and lifestyle questions, participants were asked: “How many times a week do you consume chocolate?”
Chocolate is known to contain plant chemicals called polyphenols that combat heart disease and may influence metabolism. The researchers suspected they might, to some extent at least, offset the unwelcome effects of high saturated fat levels in chocolate bars and sweets.
A study released by San Diego's University of California found regular consumption of wine and chocolate can help you lose weight.
While dark chocolate is most beneficial, caramel certainly can't hurt!
Pedro says jokingly, "A solid piece of dark chocolate has your health benefits. But you know, you have to get the muscles of your mouth moving. It's burning calories."
As for wine, Mike Palazzolo, at Rockford's Rogue River Winery says a deep red wine is good for your heart, weight loss, and stress relief.
So cheers to a liquid diet. That is until Saint Mary's Healthcare's dietitian sets Barwacz straight.
Six ounces of wine, and a small chocolate has health benefits because they come from plants rich in phytochemicals.
Lozicki says, "What these phytochemicals do in plants is keep plants healthy, keep it fighting off bacteria, fungus, different infections that would cause disease in that plant."
By eating phytochemicals- whether in chocolate, wine, or vegetables- our bodies absorb all those health benefits.
