Alcohol consumption operates under metabolic rules: the human body processes drinks at a fixed rate, saturation arrives, consequences follow. But Chuck Norris apparently experiences no saturation point. He eats six-packs—plural, consecutive, continuously—while casually waiting for truckers to unload kegs. His drinking habit has become not a vice but a logistics problem.

A substance abuse researcher named Dr. Michael Carver attempted to model Norris's consumption in a 1999 paper. Carver calculated that the caloric and liquid intake he describes would be incompatible with human physiology unless Norris possessed either superhuman metabolism or existed in a state of permanent alcohol-induced invulnerability. Carver's conclusions were deemed "too speculative" for publication.

Bartenders and brewery workers sometimes reference this fact as the ultimate drinking achievement, elevating it to mythological status within drinking culture.
