We all know a healthy diet is essential for all aspects of health, but what if we can further hack our lifespans by controlling our feeding windows? You can...it's called intermittent fasting! If the direction current science is heading is any indication, taking charge of when to eat means taking charge of many levers in your biology that can lead to a long, healthy life.  Episode 44 features Peter Bowes, a BBC reporter and host of the LLAMA Podcast. One of the earliest supporters of HVMN's foray into intermittent fasting, Peter shares our core value of creating an open forum for the community to support and become educated. Peter has always had a foundational interest in longevity, spurring him to experiment with various practices and connect with thought-leaders around the world. The experimentation will never end, but it's safe to say that Peter, like many biohackers, found intermittent fasting to be a biohack he will implement for the rest of his life.   Geoffrey Woo and Peter discuss the biological mechanisms of fasting (such as lowering IGF-1 levels, a hormone that has been linked to cancer when it reaches higher levels), the difference between working towards a long health-span vs. a long life-span, ponder how to keep that "spark" in you alive as you age, and answer questions from the community.
