Aaron Hartman, MD (speaker) explains that certain yeasts in the body produce "pseudo neurotransmitters" that influence the brain to create specific food cravings. He links this mechanism to the common experience of being "hangry," notes that these yeast-driven cravings can be difficult to remove and often require gradual dietary changes, and warns they can have real health consequences.

My son has a shirt that says, you know, forgive me for what I said when I was hangry. That actually is related to the yeast creating these things called pseudo neurotransmitters, which are things that go to your brain and make you want to eat what feeds them. And so it can be kind of hard to remove those things. You have to do it slowly. And that's where sometimes these diets you do over a period of time, but this is a real thing that can have real health consequences.
