Calorie restriction
Calorie restriction
Calorie restriction (pronounced: /ˈkaləri rɪˈstrɪkʃən/), also known as caloric restriction, is a dietary regimen that reduces calorie intake without incurring malnutrition or a reduction in essential nutrients. The etymology of the term comes from the Latin calor meaning "heat", and the English restriction meaning "a limiting condition or measure".
Overview

The concept is based on the idea that reducing the energy intake of an organism may protect against diseases and increase lifespan.
Mechanism of action
The exact mechanism of action of calorie restriction is not fully understood. However, it is believed to work by reducing metabolic rate and oxidative stress, improving insulin sensitivity, and altering hormonal function. It may also induce beneficial changes in gene expression and function.
