Time-restricted eating is a fundamental daily practice for health, while prolonged fasting is for deeper health benefits.

“So on a very simple sense if I want to relate time-restricted eating and then maybe long-term fasting, one day of fasting, two days of fasting, or four days of fasting, which definitely have much more benefit, then it's almost like taking care of your teeth. So brushing every day is like time-restricted eating. There's the minimum one can do and that's something necessary to take care of your teeth. But, again, once in a while, maybe twice a year or three times a year or once a year, depending on how much you want to take care of your teeth, you want to go see a dentist. So that's almost like a prolonged fast one has to do once a year.”
