Resveratrol in grapes stimulates obesity fighting hormone

Resveratrol properties for fighting obesity have been found by researchers.

Scientists have discovered the health compound, a polyphenol, found in grapes stimulates an important fat regulating hormone known as adiponectin that is linked to obesity.

The hormone has many health benefits, some of which have recently been discovered. Adiponectin stimulates appetite, helps control blood sugar levels and is found to be lower in obese individuals. In mice fed a high fat diet, higher levels of adiponectin made them resistant to obesity.

Higher levels of adiponectin produced by resveratrol could mean less risk for type 2 diabetes, heart disease and even cancer.

Senior author Feng Liu, Ph.D., professor of pharmacology and member of the Barshop Institute of Longevity and Aging Studies at University of Texas Health Science Center confirmed findings that resveratrol stimulates adiponectin in lab and mouse studies that could lead to obesity treatment options.

Liu says, “Results from these studies should be of interest to those who are obese, diabetic and growing older.” He also says understanding how resveratrol stimulates the beneficial fat hormone could lead to new treatment options for the conditions and other age-related illnesses.

Last year the same researchers made an important anti-aging discovery that shows resveratrol stops activity of the mammalian target of rapamycin (mTOR). Mice were found to live longer with decreased TOR activity, leading scientists to pursue the mTOR pathway response for clues that might help people live long, healthy, disease free lives.

Resveratrol is shown to have many health benefits. It is found naturally in grapes and is linked to the health benefits of drinking red wine. The new findings show resveratrol stimulates the beneficial fat hormone adiponectin that can help fight a variety of diseases brought about by obesity.

On-The-Job Weight Loss: Worksite Programs Work

Employer-sponsored programs for weight loss are at least partially effective at helping workers take off extra pounds, according to a new review of recent studies.

“For people who participate in them, worksite-based programs do tend to result in weight loss,” said co-author Michael Benedict, M.D. Intensity matters, he found. “The programs that incorporated face-to-face contact more than once a month appeared to be more effective than other programs.”

Since most employed adults spend nearly one-half of their waking hours at work, such programs could have enormous potential in making a dent in the obesity epidemic, according to Benedict, a researcher at the Institute for the Study of Health, Division of General Internal Medicine at the University of Cincinnati College of Medicine.

The systematic review appears in the July-August issue of the American Journal of Health Promotion.

Benedict and colleague David Arterburn, M.D., looked at 11 studies published since 1994. Most involved education and counseling to improve diet and increase physical activity and lasted anywhere from two months to 18 months. Forty-six percent of the studies involved low-intensity interventions, 18 percent were moderate intensity and 36 percent were high intensity.

In studies that compared the two groups, participants lost an average of 2.2 pounds to almost 14 pounds, while non-participants ranged from a loss of 1.5 pounds to a gain of 1.1 pounds.

However, it was hard to draw conclusions about weight-loss maintenance, Benedict said. “People who participate in these programs can lose weight but we aren’t really sure what happens after that.”

So far, few data exist to show how much money employers could save if they incorporate worksite weight-loss programs. “Employers want to know that what they’re doing will have a positive return on investment,” Benedict said.

Studies have shown that other worksite health interventions — such as those aimed at smoking cessation and blood pressure reduction — benefit employers financially, usually within only two to three years, Benedict said. “Worksites have a tremendous potential to have a public health impact, but more research is needed.”

Develop a Plan for Lifelong Health, Not Just Short Term Weight Loss

Weight Loss Program

Amid the daily barrage of fad diets and weight loss books, it can be easy to lose sight of the big picture: achieving overall good health.

Too often, people adopt the latest diet, which may work for a while, but then they hit weight loss plateaus and ultimately end the diet in frustration.

By putting more emphasis on your health, experts agree that you can raise your overall self esteem, resulting in healthy eating, weight loss and improved health.

It is the official position of the American Dietic Association that if food is consumed in moderation with appropriate portion size and combined with regular physical activity, all foods can fit into a healthful diet.

If you have gone from one diet to the next throughout your life, it’s time to get back to basics and focus on your overall health.

Determining Healthy Weight for Children

Body mass index, or BMI, is commonly used to measure a person’s healthy weight. Does BMI apply to children as well as adults?

Pediatric specialists say the best guide for determining a healthy weight for children is to use growth charts, which provide a range for normal weight and indicate when a child might be over- or underweight for their height. Discuss your child’s growth with your pediatrician to clarify any concerns you may have.

Healthy weight is important to children’s growth, development and overall happiness. Kids who learn to enjoy a variety of foods and get regular physical activity enjoy childhood and develop a healthful lifestyle.
