The series of chemical changes which take place in an organism, by means of which food is manufactured and utilized and waste materials are eliminated.

The process by which, on the one hand, food is built up into living material, and, on the other, living matter is broken up and decomposed.

Every day science is getting closer to the control of metabolism. – The Dream Doctor by Arthur B. Reeve

2. The metabolism in pellagra shows certain definite changes from the normal, which point to decreased gastric secretion and increased intestinal putrefaction. – The Vitamine Manual by Walter H. Eddy

Just as soon as the diet is made a little more rigid and the sugar metabolism improves, then exercise can be taken and will benefit the patient. – Psychotherapy by James J. Walsh

A cure consists in changing the manner of living to such a rational standard that full resistance and a balanced metabolism is established. – How and When to Be Your Own Doctor by Dr. Isabelle A. Moser with Steve Solomon

Despite all the laws of physics, their body temperature had remained constant after it had reached seventy- four, showing that some form of very slow metabolism was going on. – The Black Star Passes by John W Campbell
