A crazy prediction: 25 years from now, what we call intermittent fasting will be called a normal daily schedule, and what we call a normal daily schedule (3 meals and some healthier snacks) will be called food addiction. And the primary reason for this change will not be even e.g. obesity but the mental effects: people will consider it an obvious truth that being constantly in a fed state dulls the mind and saps motivation and generates akrasia and generally harms productivity.

They will look back to us and think these people went through life half-asleep because they went through life constantly (nearly) sated.

They will says stuff like "you are a like a dolphin: if you feed yourself before you jumped through all the hoops you planned for that day, you won't jump through them".

Arriving to work with a breakfast in hand will be a bit like arriving to work with a beer in hand: if you roll best that way it is not for others to judge, but most people will prefer to work sober and sharp - and that means literally staying hungry. Today we joke about having a food coma and difficulty to concentrate after a work lunch, fixing ourselves up with coffee: this will sound a lot like as an 1950's person complaining that he finds it hard to concentrate after a two-martini lunch sounds today.
