Grantee in the News: John Newman on Ketogenic diets in Cell Metabolism View MoreBACK

On September 5, 2017, Cell Metabolism published research by 2014 Paul B. Beeson Emerging Leaders Career Development Award in Aging scholar and 2011 Hartford Scholars in Geriatric Medicine recipient, John Newman, MD, PhD, that was picked up by WIRED, Popular Science, and the Guardian.

The study, Ketogenic Diet Reduces Midlife Mortality and Improves Memory in Aging Mice, examined mice with three diets: a normal high-carbohydrate diet, a zero-carbohydrate ketogenic diet, and a high-fat, low-carbohydrate diet that was not ketogenic.

The researchers found that ketogenic diet-fed mice had a lower risk of dying as they aged from one to two years old, although their maximum lifespan was unchanged.

They also found that these mice performed at least as well on memory tests at old age as they did at middle age, while mice eating the normal diet showed an expected age-associated decline.

In a related feature story, Dr. Newman told MedicalExpress:"We were careful to have all of the mice eating a normal diet during the actual memory testing which suggests the effects of the ketogenic diet were lasting. Something changed in the brains of these mice to make them more resilient to the effects of age. Determining what this is, is the next step in the work."
