Good Foods Maintain Good Health – Strength Magazine – June, 1926

Food is required to replace the dying parts and to furnish heat and energy to the body. The weight of a young man after taking part in a baseball game, or other vigorous exercise, during which no food or water has been taken will, as a result, be several ounces less than before he started to play; but in the same period of time the weight of the, young man who sat quietly and watched the baseball game will show almost no decrease in weight. This shows that the muscles of the body wear out with use: Some of the worn out parts pass off in the sweat and breath.
