The millionaire on a strict diet who's trying to age backward says he has no 'desire' for cheat days.
Tech exec Bryan Johnson told Fortune it makes him "sick" to think of pizza and donuts.
Bryan Johnson is following a strict diet in his attempt to reverse his biological age, but still says he has no interest in junk foods.
Johnson also said, contrary to popular belief, he's happy following his strict regimen, which Bloomberg previously reported costs him $2 million a year.
Johnson's strict diet includes consuming exactly 1,977 calories each day.
