The benefits of calorie restriction

Two years of low-calorie nutrition in the body of the participants in a scientific study actually rebooted the immune system and metabolism, contributing to an increase in the duration of healthy life years. The calorie-restricting participants experienced rejuvenation of the thymus gland, a key organ of the immune system that produces T-lymphocytes. Usually the thymus ages faster than other organs, even in healthy 40-year-old people, the thymus gland is 70% non-functional. As we age, the thymus produces fewer T cells, which increases the risk of infections. In addition to improving immune defenses, calorie restriction led to changes in adipose tissue that increased the body's ability to burn fat stores into energy.
