Bryan Johnson argues sleep is the most powerful anti-aging intervention. His tracking shows deep sleep directly predicts his willpower the next day: more slow-wave sleep means less nighttime binge-eating. He measured meal timing down to 15-minute increments against bedtime to find the link.
Maybe elaborate on the sleep thing. Why is sleep so important? I think sleep is a contender for being the most powerful health intervention in existence. It's magical what it does if you're well rested and what your body can do. And I mean, for example, I know when, when I eat close to my bedtime. And I've done a systematic study for years looking at like 15 minute increments on time of day and where I eat my last meal. My willpower is directly correlated to the amount of deep sleep I get. So my ability to not binge eat at night is based upon how much deep sleep I got the night before.
