In the video below, Steve Hill from Lifespan.io and I talk about findings from a recent paper (https://content.iospress.com/articles/journal-of-alzheimers-disease/jad200306) that supports a role for the gut microbiome on Alxheimer’s disease. Check it out!

The Impact Of The Microbiome On Lifespan

1 Reply

Germ-free mice (animals don’t have a microbiome) live longer than microbiome-containing mice, but it’s impractical for people to live in a bubble for their entire lifespan. As a more practical approach, which microbiome-derived factors impact lifespan, and can they be modified?

Dietary supplementation with acarbose increases lifespan, and one reason for that may involve reduced circulating levels of glucose, but the other side of that story involves increased gut bacterial production of short chain fatty acids (SCFAs). Whether acarbose will increase lifespan in people is unknown, and with the goal of increasing lifespan, are there other ways to increase SCFAs?

How does the gut microbiome and its metabolic products affect muscle mass, muscle composition, and physical function? In this presentation, I review the evidence, then I present recent data from our group.

An Interview With Dr. Michael Lustgarten: Biohacker, Scientist

  • How (and why) did you get involved in research in aging and the human microbiome?
  • How did you get started in health optimization /  quantified-self?
  • What are your thoughts on biological age testing? Which tests (epigenetic, blood biomarkers, telomere, etc) and specific services do you believe to be most useful?
  • What else is in your biohacking stack? (Nutrition / diet, fasting, wearables or other products, fitness routines, supplements, drugs, services, lifestyle practices, sleep, mental)

And much more!
