Bryan Johnson describes how eating ultra-processed foods at night kills his deep sleep, leaving him groggy and irritable the next day. That impaired state makes him more likely to overeat again, creating a self-reinforcing cycle where one bad meal triggers worse sleep, worse mood, and another bad meal.
When evening Brian was eating food at that time period. Ultra processed foods and too much it would eliminate my deep sleep. The next morning I'd wake up and feel awful. My decision making capacity the next day to do other things I need to do is severely impaired. I'm grumpy, I'm irritable, I am an impaired person. And once you start that chain of cascading actions, what's the likelihood I'm going to overeat again? Extremely high. And so it just creates this vicious loop where I just have no time. I'm getting dunked under the water every day and I just can't even catch my breath.
