So without further delay, here's today's sneak peek of the Ask Me Anything episode. Welcome to Ask Me Anything AMA episode 72. For today's AMA, We focus on a topic we initially covered all the way back in AMA 11 in January 2020, which is all things relating to fasting. This is a topic in which my thinking has evolved greatly, as well as one that we get an almost infinite number of questions about from our subscribers.

In this episode, we discuss the various types of fasting, which oftentimes can be used interchangeably, but actually can mean very different things. We talk about the reasons why people might fast and its potential benefits, focusing on body composition, metabolic health, overall lifespan extension, cardiovascular disease, cancer prevention, cancer treatment, Alzheimer's and Parkinson's disease, along with various autoimmune symptoms, including arthritis and more. We talk about the potential negative aspects of fasting that everyone should be aware of. And finally we wrap it up with a framework to help you think about this for yourself. If you're a subscriber and you want to watch the full video of this podcast, you can find it on the show notes page.
