Required food consumption is as follows:

For any day in which a character is occupied in no physical labor, but is at rest, food required is 2 lb. per day, half of which may be in liquid form (excepting pure water). This includes persons who are being transported by ship or wagon, who are taking no part in driving or maneuvering said vehicle.

A character who is occupied with driving or maneuvering a vehicle, like a ship or wagon, or who is riding on horseback, or walking throughout the day, requires 4 lb. of food per day, one pound of which may be in liquid form (excepting water).

A character who has taken part in battle, regardless of the number of times which they have swung a weapon, or whether or not they have taken damage, requires 6 lb. of solid food on that day (over and above any liquids also drunk).

Characters who choose to live on half rations may accept a penalty of -2 to hit and -1 damage when attacking.

Nutritional rules are in the proposal phase.
