Cutting calories increases lifespan

THE dream of living forever permeates human culture.

As the science of aging progresses, scientists have made tremendous progress in extending human life, studying and discovering all safe methods (including genetic engineering and regenerative medicine) to increase person’s lifespan.

From lowering infant mortality rates to creating effective vaccines and reducing deaths related to disease, science has helped increase the average person’s life span by nearly three decades over the past century, according to the Centers for Disease Control and Prevention (CDC).

According to scientists, reducing calories in your diet could help you live longer. In a study published in the Journal of Nutrition, researchers found that naturally chubby mice lived longer when fed reduced-calorie chow than lean mice that ate the low-cal food.

Previous studies have indicated that lab animals, like the nematode C. elegans, the fruit fly Drosophila and lab mice, all lived almost twice as long when fed an almost-starving diet (30 percent fewer calories than usual), but the effect on humans isn’t clear. A study published in July 2008 indicated that eating less could add five years to the life of an average human.

The restricted diet seems to work by lowering metabolic rate, reducing the frequency of age-related diseases by reducing the amount of “free radicals” produced naturally by our bodies.

According to the Mayo Clinic, simple substitutions can make a big difference when it comes to cutting calories. For example, you can save 60 calories a glass by drinking fat-free milk instead of whole milk. Instead of having a second slice of pizza, reach for some fresh fruit. Or snack on air-popped popcorn instead of chips.

The sizes of your portions affect how many calories you’re getting. Twice the amount of food means twice the number of calories.
