But your body’s epigenetic, or biological, age—based on the true age of cells, tissues, and organ systems as dictated by lifestyle and genetics—is another, and keeping it low is the key to healthy aging and a longer life span. A new small study finds that certain nutritional choices may be a way to keep biological age low and even reverse it.

Specifically, found the researchers in Spain, following a very low-calorie ketogenic diet (VLCKD) could be the answer.
