Prolonging life by eating a low-cal, high-nutrition diet?
We all know that paring our bodies down to a healthy weight is one of the best ways to prolong life, but did you know eating a low-calorie, high-nutrition diet—in and of itself—can help you live longer?
In the April 5, 2006 issue of the Journal of the American Medical Association (JAMA), Luigi Fontana, M.D., Ph.D., assistant professor of medicine at Washington University in St. Louis, said that their studies had shown that after an average of six years on a calorie-restricted diet, people’s hearts functioned like that of much younger people. In the same issue of JAMA, researchers at Louisiana State University reported that six months of calorie restriction reduced fasting insulin levels and body temperature, two key markers of aging.
However, the trick of a low-calorie diet is to still consume enough nutrients. Achieving that balance is the focus of a group called the Calorie Restriction Society. The group, which calls themselves CRONies (Calorie Restriction with Optimal Nutrition), have developed ways to achieve the balance consistently. The group’s focus is specifically prolonging life, not weight loss. Fontana has conducted research with the group and found that their hearts appeared more elastic than those of similar age and gender. Specifically, their hearts were able to relax between beats in a way similar the hearts of younger people.
Fontana and his team’s studies are still ongoing, but if their hypothesis proves true, it could be just one more reason to eat a diet packed with as much nutrition and as few calories as possible.
For those of us considering lap-band surgery, eating a low-calorie, high-nutrition diet could be a good lifestyle choice. Since eating less will be a fact of life after surgery, it would make sense that we get the most bang for our new stomach capacity. Our bodies need certain nutrients to function properly, and in our efforts to shed weight, we shouldn’t deprive them of what they need.
