What does a reduction in energy intake without malnutrition associate with?

A reduction in energy intake without leading to malnutrition is associated with improved lifespan due to the body's response to caloric restriction. Research has indicated that moderate caloric restriction can lead to various biological changes that enhance longevity, including improved metabolic health, reduced oxidative stress, and better regulation of cellular mechanisms associated with aging.

These adaptations promote health benefits such as lower risks of chronic diseases, which are commonly associated with aging, such as cardiovascular disease and diabetes. In animal models and some human studies, this practice has been shown to extend lifespan significantly. Thus, the connection between caloric restriction and increased lifespan highlights the importance of managing energy intake while maintaining nutritional adequacy to promote overall health and longevity.
