Journal Club With Dr. Peter Attia | Metformin for Longevity & the Power of Belief Effects
O epizodě podcastu
In this journal club episode, my guest is Stanford and Johns Hopkins-trained physician, Dr. Peter Attia, M.D., who is also the host of The Drive podcast and the author of the bestselling book "Outlive: The Science & Art of Longevity."
We each present a scientific paper and discuss the findings' strengths, weaknesses and actionable takeaways.
First, we discuss an article that addresses whether taking the drug metformin can enhance longevity. Then, we discuss an article on belief effects (similar to placebo effects), showing how the effects of a drug on the brain and cognition depend on one's belief about the dose of the drug taken, not the actual dose.
Our conversation also highlights how to read, interpret and critique scientific studies. This episode ought to be of interest to those curious about health and longevity, medicine and psychology and for anyone seeking to better understand how to read and digest scientific findings.

Popis podcastu
The Huberman Lab podcast is hosted by Andrew Huberman, Ph.D., a neuroscientist and tenured professor in the department of neurobiology, and by courtesy, psychiatry and behavioral sciences at Stanford School of Medicine. The podcast discusses neuroscience and science-based tools, including how our brain and its connections with the organs of our body control our perceptions, our behaviors, and our health, as well as existing and emerging tools for measuring and changing how our nervous system works.
Huberman has made numerous significant contributions to the fields of brain development, brain function, and neural plasticity, which is the ability of our nervous system to rewire and learn new behaviors, skills, and cognitive functioning. He is a McKnight Foundation and Pew Foundation Fellow and was awarded the Cogan Award, given to the scientist making the most significant discoveries in the study of vision, in 2017.
Work from the Huberman Laboratory at Stanford School of Medicine has been published in top journals, including Nature, Science, and Cell, and has been featured in TIME, BBC, Scientific American, Discover, and other top media outlets.
In 2021, Dr. Huberman launched the Huberman Lab podcast. The podcast is frequently ranked in the top 10 of all podcasts globally and is often ranked #1 in the categories of Science, Education, and Health & Fitness.
