Feed your mouse lots of butter

As I often note here advice on what you should eat seems to change with the seasons. Now come researchers at the UC Davis School of Veterinary Medicine to tell us that a high-fat diet will help you live longer.

They extrapolate from a mouse study, of couse.
“The results surprised me a little,” said nutritionist Jon Ramsey, senior author of the paper that appears in the September issue of Cell Metabolism. “We expected some differences, but I was impressed by the magnitude we observed — a 13 percent increase in median life span for the mice on a high-fat versus high-carb diet. In humans, that would be seven to 10 years. But equally important, those mice retained quality of health in later life.”
I bet the mice were surprised, too.

Ketogenic diets have gained popularity for a variety of health benefit claims, but scientists are still teasing out what happens during ketosis, when carbohydrate intake is so low that the body shifts from using glucose as the main fuel source to fat burning and producing ketones for energy.
“In this case, many of the things we’re looking at aren’t much different from humans,” Ramsey said. “At a fundamental level, humans follow similar changes and experience a decrease in overall function of organs during aging. This study indicates that a ketogenic diet can have a major impact on life and health span without major weight loss or restriction of intake. It also opens a new avenue for possible dietary interventions that have an impact on aging.”
Go on. Have a burger.
