#302 - Social Connection, Longevity, and the Hidden Health Risks of Isolation | Dr. Julianne Holt-Lunstad & Mike Haney

<p><strong>You probably spend more time thinking about protein than friendships.</strong></p><p>According to today&#39;s guest, you’ve got it backward.</p><p>In this episode of <em><strong>A Whole New Level</strong></em>, Mike Haney sits down with Dr. Julianne Holt-Lunstad, one of the world&#39;s leading researchers on social connection and health.

And why simply <em>not feeling lonely</em> doesn&#39;t necessarily mean you&#39;re getting enough social connection, as well as why even weak connections matter a lot to a healthy social life.</p><p><br></p><p><strong>Free course: Improve your metabolic health</strong></p><p>Get our free email course on how glucose, nutrition, exercise, sleep, and measurement can help you build habits that support better energy and long-term health: <a href="https://www.levels.com/partner/multimedia?utm_source=podcast&utm_medium=link&utm_content=wnl&partner=Holt-Lunstad" target="_blank" rel="noopener noreferer">⁠⁠⁠⁠⁠https://levels.link/wnl⁠</a></p><p><br></p><p><strong>🎙️ About the Guest: </strong></p><p>Dr. Julianne Holt-Lunstad is a professor of psychology and neuroscience at Brigham Young University and one of the world&#39;s leading researchers on social connection and health.
