Caloric restriction is a research area focused on studying the effects of reducing calorie intake on various biological processes and health outcomes. This area of research has gained attention due to its potential to extend lifespan, improve metabolic health, and delay the onset of age-related diseases. Studies have shown that caloric restriction can lead to changes in metabolism, gene expression, inflammation, and cellular processes that may contribute to improved health and longevity. Researchers are also investigating the mechanisms by which caloric restriction exerts its effects, as well as strategies to mimic its benefits without the need for severe dietary restriction.
