Eating less might be key to a longer life, reduction in caloric intake have a significant decrease in metabolism, improves biomarkers associated with slower aging and longer life span, this leads to lower core body temperature, lower blood sugar and insulin levels, and significant drops in hormones that moderate metabolism. Calorie restrictions reduce aging process in animals.
According to Anderson, an associate professor who studies aging and calorie restriction at the University of Wisconsin School of Medicine and Public Health, aging studies in animals linked lower calorie intake to longer lives. Researchers recruited healthy participants with an average age of 40 to follow a calorie-restricted diet for two years. The study participants cut 25 percent of their daily caloric intake using three different models of a healthy diet.
They achieved 15 percent reduction in calorie intake that was sustained for the two years, the group lost about 20 pounds in the first year. Tests showed changes in metabolism and body processes mirroring those that have been linked to longer life span in animals and people and reduction in oxidative stress related to their lowered metabolism. The byproducts of making energy is oxygen radicals, these accumulate in the body and cause damage to cells and tissues, the damage can cause cells to age faster and contribute to different diseases.
