( Saint Louis researcher and member of W...)Lose Weight To Reduce Risk Of Diabetes – Says A New Researc,Health

Saint Louis, researcher and member of Washington University team of scientists induces a query: Which works best in fighting the risk factors // for diabetes – exercise or diet?

It's a toss up – answers Louis, who is currently involved in new research, a part of longevity study funded by NIH, examining whether a calorie-restrictive diet can extend lifespan of people who are under the mercy of diabetes.

"People weren't way out of whack in terms of their body composition," Weiss says.

The study participants were divided into three groups –- with 18 each in the diet and exercise groups and 10 in the control group. The yearlong study was funded by the National Institutes of Health.

All participants had their insulin action and glucose tolerance, which both are markers for diabetes, evaluated at the beginning and end of the study. In addition, their weight, body composition and energy intake were measured at the beginning of the study and at one, three, six, nine and 12-month intervals.

Those who restricted calories met weekly with a dietitian who helped them develop individualized menu plans and guided them to reduce portion sizes and replace high ca
