Diet of Anti-Aging
Calorie restriction is the practice of eating less than body needs to maintain normal weight. Exactly how much less a person eats on a calorie restriction diet varies. In research studies, people practicing calorie restriction ate 20 percent to 25 percent less than their bodies needed. For example, a person who needs 2,000 daily calories for weight maintenance might eat 1,500 to 1,600 calories a day on a calorie restriction diet. People who follow a calorie restriction diet do so in hopes of slowing the aging process and extending their lives.
But beyond restricting how much food they eat, people who subscribe to calorie restriction carefully monitor their food intake to ensure they're getting all the vitamins and nutrients they need. This can mean choosing more foods that are full of nutrients, but low in calories, such as vegetables and whole grains. Interest in calorie restriction has grown as studies show the diet can extend the lives of animals. Only limited studies have been conducted in people.
