Having reversed much of my own chronic fatigue, mostly through diet, I find myself increasing being an evangelist of avoiding foods that fuel inflammation.
It is a remarkable feeling to feel brain fog lift directly after a big diet change - particularly because you didn't know you had brain fog until it lifted.
I've written two of my medium articles over the last week that touch on this exact topic, and feel to my bones that I have become somewhat of an evangelist of what I consider to be a solution to these challenges.
