Awardee in the News: Longo interviewed on NPR on Calorie Restriction and Metabolism View MoreBACK

On April 2, 2018, NPR interviewed 2013 Vincent Cristofalo Rising Star Award in Aging Research recipient Valter D. Longo, Ph.D. on calorie restriction and metabolism.

The segment, “You May Live Longer By Severely Restricting Calories, Scientists Say,” highlights a study by Leanne Redman with fifty-three participants where one group ate their normal meals and the other group was on a calorie restricted diet.  The results were that the group on the calorie restricted diet had a slower and more efficient metabolism and lower blood pressure, cholesterol, and triglycerides.

Dr. Longo lends expert insights based on his research on calorie restriction and healthspan. In response, he notes that severe calorie restriction can ultimately lead to weight gain. “Basically, you have to eat progressively less to maintain the same weight,” he states.

Dr. Longo also expands on the consequences of a slower metabolism for many Americans. “For most people, if you consider 70 percent of Americans are either overweight or obese, then you can see how, for most people, this will be a big problem--having a slower metabolism that potentially could be carried for years.”

Longo advocates for a diet of mini-fasts rather than consistent calorie restriction.
