In This Episode:
Dr. K talks with geriatrician and geroscientist John Newman, MD PhD, about the biology of aging and his research on ketogenic diets and geriatric syndromes. Dr. Newman is an assistant professor at the Buck Institute for Research on Aging and in the Division of Geriatrics at UCSF. He also works on improving the hospital care of older adults. They discuss:
- How aging biology research helps us understand fundamental aging processes that affect all animals
- The complex relationship between aging and disease, and what is the geroscience hypothesis
- Cellular hallmarks of aging, and biomarkers to assess physiological age
- How we can assess someone’s physiological age
- Why biomarkers of aging aren’t as useful as functional assessments of older people
- How insulin, fasting, and other aspects of metabolism are related to aging
- What Dr. Newman has learned from studying ketones and aging in mice
- What is known about ketogenic diets in humans
- What’s been shown to improve healthspan and lifespan (in mice)
- Why metformin, a diabetes drug, is a “really good drug”
- Why things that slow aging in the lab may not work in humans or under real-world conditions

In your excellent interview with John Newman he mentioned a finding from a large group of related mouse strains showing that individual genetics plays a big role in how one responds caloric restriction. i happened to be the person responsible for breeding those strains, which have been used in a lot of different fields of study. (Just had to get that in!)
Love the variety of interviews you do, I just discovered your podcast, and am adding your site to my blog:

Look forward to more!

Thank you, so glad you are enjoying the podcast. I’ll have to let John Newman know about this comment 🙂
