Intermittent fasting, the type of diet made popular by Dr Michael Mosley, is good for your brain as well as your body - according to new research.
The study found better brain function in people who follow an intermittent fasting diet, which involves only eating on certain days or during certain hours of the day.
The research followed adults with obesity and insulin resistance - which both lead to a higher risk of Alzheimer's disease and cognitive decline.
Researchers at Johns Hopkins Medicine and the National Institute on Aging assigned people either a standard healthy diet or an intermittent fasting diet.
