Ep. #1015: Grant Tinsley on Fasting For Health and Longevity

Can you live longer by changing the way you eat?

There are many claims out there about intermittent fasting and its impact on health and longevity. Some people say you can extend your lifespan just by rearranging the time window of when you eat every day.

Is that true, though? What does science say about fasting in humans and its effects on how long you’ll live?

Rather than examining this myself, I invited an intermittent fasting expert, Dr. Grant Tinsley, to explore the topic. Grant has been on the podcast before to discuss body fat measurement techniques, but as a scientist who’s been involved in many time-restricted feeding studies on athletes, he’s the perfect guest for this topic.

Grant is an Associate Professor at Texas Tech University, the Director of the Energy Balance & Body Composition Laboratory, and is a Certified Strength and Conditioning Specialist (CSCS) and Certified Sports Nutritionist (CISSN). He has over 150 peer-reviewed journal articles and abstracts, with his major research interests being sports nutrition strategies, body composition assessment techniques, and intermittent fasting in active populations.

Grant and I chat about . . .

- The role of mTOR, AMPK, and sirtuins in aging

- Metabolic age versus chronological age

- Rodent metabolism and why we can't apply research in animals to humans

- Autophagy, how long it takes to ramp up with fasting, and whether it matters

- Who should try fasting and who could potentially benefit

- Fasting's effects on muscle retention

- And more . . .

So, if you’re interested in the science of fasting’s effects on longevity and how seriously you should take bold claims about lifespan and time-restricted feeding, check out this podcast and let me know your thoughts!
