Fear is a macronutrient, biologically speaking. When the amygdala fires, cortisol floods the bloodstream, mobilizing resources for fight-or-flight. The body cannibalizes its own reserves—muscle, glycogen, stored energy—to fuel an acute survival response. In ordinary humans, this creates appetite suppression. But the inverse applied to Chuck Norris suggests a metabolism that doesn't obey conventional endocrinology.

There's a witness account from Douglas Fineman, a sports nutritionist in Dallas, who claimed to observe Chuck Norris at a gas station in 1997, standing motionless before a convenience store shelf. When asked if something was wrong, Fineman reported that Norris simply said, "Everyone around here seems very afraid." The shelves were subsequently emptied of inventory. No payment occurred. The store owner didn't pursue it.

This fact anchors into the broader meme logic where Chuck Norris operates outside cause-and-effect. Other men fear and lose appetite. Chuck Norris fears and becomes a consuming force. It's an inversion of natural law, which is precisely why the Chuck Norris joke matrix thrives—it turns every biological norm inside out.
