 slightly. 



We observe that after the quantity of protein digested reached 

 150 grams daily there was no increase in the protein stored up in 

 the body, even though the amount in the food was still further 

 augmented. 



That an exclusive protein diet will not produce body tissue is 

 well illustrated in the so-called " Banting cure" for obesity, 

 where the patient is put on a meat and fruit diet, especially the

 and on the basis of this experiment concludes, contrary to the
