We are all aware that counting calories is essential to dieting and maintaining a healthy weight, but there may be an even more direct correlation between reduced caloric intake and living longer. According to one new study, by reducing your caloric intake by 25 percent, you may live longer than those who don’t.
Researchers from the Washington University School of Medicine in St. Louis monitored the core body temperatures of 24 participants in their 50s who adhered to a calorie-restricted diet for at least six years. They compared these to the core body temperatures of 24 others who ate a higher calorie diet for the same amount of time. A third group, consisting of 24 endurance runners in the same age group, was also studied to determine if being lean was enough to maintain a lower body temperature.
Results revealed that those who maintained restricted-calorie diets achieved reduced core body temperatures, similar to those seen in mice that lived longer on reduced-calorie diets. Researchers also pointed out that lowering core body temperature alone isn’t enough to increase lifespan, noting that someone who practices unhealthy lifestyle habits such as smoking and excessive drinking in conjunction with calorie restriction will not necessarily yield the same results. Continued research needs to be done to more closely define the relationship between calorie consumption, core body temperature and increased lifespan.
