How can calorie restriction affect overall health?

Answer 1

ANSWER:- 1. Caloric restriction is an experimental tool that utilizes “under nutrition without malnutrition.” In other words, caloric restriction means lowering typical calorie consumption by 30 to 40 percent, while maintaining all the necessary nutrients and vitamins to support life.

ANSWER:- 2. Caloric restriction has been shown to increase both the average and the maximal lifespan in paramecia(creatures made of a single cell), worms, spiders, insects, and rodents. Non-human primates are now being tested, but the complete outcome of these tests will not be known for several decades because monkeys have relatively long lifespans compared to other animals. Preliminary results suggest that calorie-restricted monkeys are healthier and tend to live longer than their freely fed counterparts. For example, one new study shows that the immune systems of aged rhesus monkeys on a calorie restricted diet resembles, in several ways, the immune systems of younger animals.

Caloric restriction may or may not extend the total number of years a human can expect to live, but of equal or greater importance, perhaps, is the possibility of adding to the number of years we can expect to remain healthy. Reducing or delaying age-related diseases until the very end of life would represent an enormous improvement in quality of life for many, if not most, older adults.
