“I constantly tell the people in my lab and other scientists, ‘You’ve got to do the experiment.’ You cannot go into it thinking that you know the answer and not do the experiment because your dogmatic belief says, ‘This is how it’s going to work.’ You’ve got to do the experiment.”

— Dr. Matt Kaeberlein

Dr. Matt Kaeberlein (@mkaeberlein) is a professor of Laboratory Medicine and Pathology at the University of Washington School of Medicine, with adjunct appointments in Genome Sciences and Oral Health Sciences. Dr. Kaeberlein’s research interests are focused on understanding biological mechanisms of aging in order to facilitate translational interventions that promote healthspan and improve quality of life for people and companion animals.

Dr. Kaeberlein is the founding director of the University of Washington Healthy Aging and Longevity Research Institute, the director of the NIH Nathan Shock Center of Excellence in the Basic Biology of Aging at University of Washington, director of the Biological Mechanisms of Healthy Aging Training Program, and founder and co-director of the Dog Aging Project.

Brought to you by Levels real-time feedback on how diet impacts your health, Athletic Greens all-in-one nutritional supplementand LMNT electrolyte supplement. More on all three below.

#610: The Life-Extension Episode — Dr. Matt Kaeberlein on The Dog Aging Project, Rapamycin, Metformin, Spermidine, NAD+ Precursors, Urolithin A, Acarbose, and Much More


This episode is brought to you by LMNTWhat is LMNT? It’s a delicious, sugar-free electrolyte drink mix. I’ve stocked up on boxes and boxes of this and usually use it 1–2 times per day. LMNT is formulated to help anyone with their electrolyte needs and perfectly suited to folks following a keto, low-carb, or Paleo diet. If you are on a low-carb diet or fasting, electrolytes play a key role in relieving hunger, cramps, headaches, tiredness, and dizziness.

LMNT came up with a very special offer for you, my dear listeners. For a limited time, you can get a free LMNT Sample Pack with any purchase. This special offer is available here: DrinkLMNT.com/Tim.


This episode is brought to you by Athletic Greens. I get asked all the time, “If you could use only one supplement, what would it be?” My answer is usually AG1 by Athletic Greens, my all-in-one nutritional insurance. I recommended it in The 4-Hour Body in 2010 and did not get paid to do so. I do my best with nutrient-dense meals, of course, but AG further covers my bases with vitamins, minerals, and whole-food-sourced micronutrients that support gut health and the immune system. 

Right now, Athletic Greens is offering you their Vitamin D Liquid Formula free with your first subscription purchase—a vital nutrient for a strong immune system and strong bones. Visit AthleticGreens.com/Tim to claim this special offer today and receive the free Vitamin D Liquid Formula (and five free travel packs) with your first subscription purchase! That’s up to a one-year supply of Vitamin D as added value when you try their delicious and comprehensive all-in-one daily greens product.


This episode is brought to you by Levels! I wrote about the health benefits of using continuous glucose monitors (CGMs) more than ten years ago in The 4-Hour Body. At the time, CGMs were primitive and hard to use. Levels has now made this technology, and the unique insights that come from it, easy and available to everyone. Levels is making glucose monitoring simple, helping you see how food affects your health through real-time feedback. I started tracking my glucose years ago to learn more about what I should and shouldn’t be eating (including quantities, time of day, etc.), based on objective data from my own, unique physiology. Keeping my blood sugar stable is critical to my daily and long-term health and performance goals. Furthermore, poor glucose control is associated with a number of chronic conditions like diabetes, Alzheimer’s disease, heart disease, and obesity. It’s important.

Want to hear another podcast episode that explores the possibilities of rapamycin? Have a listen to the conversation I had with Peter Attia, David M. Sabatini, and Navdeep S. Chandel at the source of this miraculous compound: Easter Island. Here, we discuss how one of the most important discoveries of medical science was almost lost, why metabolism (along with longevity) research is key to treating a long list of diseases, intermittent dosing of rapamycin, parenting advice from scientists on confidence and conflict, the necessary failures of good science, good fonts versus bad fonts, “non-potato” relationships, and much more.

MORE DR. MATT KAEBERLEIN QUOTES FROM THE INTERVIEW

“If you look at almost all of the major killers in developed countries, they all share a single greatest risk factor, and it’s how old you are. And that’s because of the underlying biology that creates a change in our physiology that is permissive for all of those diseases to happen.”
— Dr. Matt Kaeberlein

“We’ve got these misbehaving cells. They’re good-for-nothing, do-nothing cells that just kind of hang out and convince the other cells to do bad stuff. So if we could get rid of them, that’d be a good thing. It turns out it’s probably not that easy.”
— Dr. Matt Kaeberlein

“Being a dog guy and wanting my dog to live longer, when that light bulb went off in my head, I was like, ‘This goddamn has to happen.’”
— Dr. Matt Kaeberlein

“I constantly tell the people in my lab and other scientists, ‘You’ve got to do the experiment.’ You cannot go into it thinking that you know the answer and not do the experiment because your dogmatic belief says, ‘This is how it’s going to work.’ You’ve got to do the experiment.”
— Dr. Matt Kaeberlein

“People pay no attention to the psychological consequences that go along with trying to practice caloric restriction or trying to practice time-restricted feeding or intermittent fasting. I’m not saying they’re bad for everybody, but I know a lot of people who’ve dabbled with these things and I would say some of the psychological effects aren’t great.”
— Dr. Matt Kaeberlein

“If you really could modulate the biology of aging, it will improve age-related immune function.”
— Dr. Matt Kaeberlein

“[Many] physicians … are very resistant to the idea of doing anything for somebody who’s not sick to keep them well. And we have to change that.”
— Dr. Matt Kaeberlein
