Researchers study whether cutting calories may help you live longer

Reducing calories over six months resulted in a decrease in fasting insulin levels and body temperature, two biomarkers of longevity, according to a study in the April 5 issue of JAMA. Longer studies are required to determine if calorie restriction changes the aging process in humans.

Prolonged calorie restriction increases life span in rodents and other shorter-lived species. Whether this occurs in humans is unknown, according to background information in the article. One theory concerning the antiaging effects of calorie restriction is its impact on metabolism, including alterations in insulin sensitivity and signaling, neuroendocrine function, stress response, or a combination of these.

Leonie K. Heilbronn, Ph.D., of Louisiana State University, Baton Rouge, La., and colleagues conducted a study to determine the effects of prolonged calorie restriction, with or without exercise, in overweight men and women. The randomized trial, conducted between March 2002 and August 2004, included 48 healthy, sedentary men and women. Participants were randomized to 1 of 4 groups for 6 months: control (weight maintenance diet); calorie restriction (25 percent calorie restriction of baseline energy requirements); calorie restriction with exercise (12.5 percent calorie restriction plus 12.5 percent increase in energy expenditure by structured exercise); very low-calorie diet (890 kcal/d until 15 percent weight reduction, followed by a weight maintenance diet).

After six months, the control group had experienced an average weight loss of 1.0 percent; the calorie restriction group, 10.4 percent; calorie restriction with exercise, 10.0 percent; and very low-calorie diet, 13.9 percent. Fasting insulin levels were significantly reduced at month 6 in all intervention groups. There were no significant changes in fasting glucose or dehydroepiandrosterone sulfate (DHEAS) levels in any group. Participants randomized to calorie restriction and calorie restriction w
