What is the calorie restriction theory of aging?

Since the 1930s, scientific research has observed that a consistent reduction in dietary intake can extend the lifespan of many laboratory animals. This discovery led to the calorie restriction theory of aging, which posits that a lowered energy intake can positively influence the biological processes that drive aging.

Understanding the Science: What is the #1 Cause of Aging?

According to the National Institute on Aging, senescence—the gradual deterioration of function—is a complex process driven by multiple interacting factors [1]. While many people search for a single, simple answer, the question of **what is the #1 cause of aging** is a scientific inquiry with a more nuanced, multifaceted answer rooted in genetics and cellular biology.
