I am not certain how generalizable this is. Because this sorts of diet research relies most often on self-reporting, I mostly read it by prepending 'People exist for which ...'. And that is good to know, and hopefully they are not outliers by too much, but it probably won't be silver bullet for everybody.
I.e. I remember hearing two twich streamers talk about their diets an one said how she really enjoys intermittent fasting, while other mentionsh how he needs to eat something at least every four hours, or he literally sees his apm in Starcraft drop :D
