Influence of Inanition on Metabolism. 



which indicates that the 30.18 grams of protein as body material furnished by 

 the food was insufficient. There was an average loss of fat accompanied by a 

 large average gain in carbohydrates. The body, however, was practically in 

 carbon equilibrium. The energy furnished by the food was less by 154 calories 

 per day than that actually resulting from the katabolism of body material.
