Diet

Outside of chlorophyllic plants and exotic creatures, most living things eat living things to survive. 
== Omnivorous (Default) ==
The GURPS default (worth 0 points) assumes an omnivorous creature that can consume some types of plants, most meats, and the occasional non-poisonous fungi.
== Carnivory and Herbivory ==
Typically, both carnivores and herbivores are represented with Restricted Diet. Carnivores have an easy time getting enough calories from meat, but a harder time getting enough of it--vice versa, herbivorous characters can eat grass almost anywhere, but will likely be eating a lot of it!
=== They eat what? ===
Typically, outside of specific religious ritual, it's considered poor form to eat one's own species--or people in general. This is usually written up as an odious personal habit.
== Exotic Creatures ==
Creatures of other planets will likely have some kind of Unusual Biochemistry, and may or may not have Restricted Diet with Substitution.
