Caloric restriction is a dietary practice that involves reducing calorie intake without malnutrition. It is often studied for its potential health benefits, including weight loss, improved metabolic health, and increased lifespan. Research suggests that consuming fewer calories can lead to better regulation of blood sugar and lower risks of chronic diseases. Many studies on caloric restriction have been conducted on laboratory animals, showing promising results in extending lifespan and enhancing overall health. While the effects on humans are still being researched, some people adopt this approach to improve their well-being and manage their weight effectively.
