Overweight

Overweight is one of Fallout GURPS disadvantages. See: Fallout GURPS.

Overview
"You are unusually obese for your race. Overweight: Determine weight normally for ST, and then increase it by 30%. Being overweight carries a reaction penalty of -1 among health-conscious societies and in areas where food is in especially short supply"

- Steve Jackson Games GURPS sources

In Fallout
With the abandonment of GURPS, Overweight was removed from the game
