Neil DeGrasse Tyson Ruins Your Zombie Fantasies Forever - Video

Sorry leptin doesn’t trigger hunger it triggers satiety. Grelin, which your stomach releases, triggers hunger. I like this guy but please get your stomach facts right

No, leptin is the satiety hormone. Leptin is what controls and adjusts your SENSATION of hunger. A zombies leptin hormone therefore could not change, adjust or it would simply not be sending the signals you normally would get when hungry.
