During a five-day fast, Peter Attia's meditative routine intensified, leading to a natural state of presence and mindfulness during walks without conscious effort.

“I talked about how I came into this with a really good meditative routine but that week it went to another level so I meditated in I've never meditated before and normally when I'm walking around the street I always have headphones on and I'm always doing something I'm either listening to a podcast listening to an audiobook listening to music or talking on the phone in other words I am never just walking around spacing out or taking in the ambient sound for some reason on that week I pretty much always I'd walk out of my building or walk out of the office or walk out of wherever I was leaving and I wouldn't even remember to put my headphones in and I would just walk and I would just look at stuff and you know be as present and mindful as any human could be and not even kind of realise it was happening until 20 minutes later when I'd be like geez I haven't even like made a phone call or checked my phone or done any of these other things”
