 carbohydrates and fats is undesirable as such excess interferes 

 with digestion. A small proportion of the ration should con- 

 sist of digestible protein which aids in the digestion and con- 

 sumption of fattening rations. Kellner recommends I pound of 

 digestible protein to 8-10 pounds of carbohydrates and fat.
