feed a cold, starve a fever

Eating more will cure the common cold, and eating less will cure a fever.1887, J. H. Whelan, "The Treatment of Colds.", The Practitioner, vol. 38, pg. 180:"Feed a cold, starve a fever." There is a deal of wisdom in the first part of this advice. A person with a catarrh should take an abundance of light nutritious food, and some light wine, but avoid spirits, and above all tobacco.1968, Katinka Loeser, The Archers at Home, publ. Atheneum, New York, pg. 60:I have a cold. 'Feed a cold, starve a fever.' You certainly know that.2009, Shelly Reuben, Tabula Rasa, Houghton Mifflin Harcourt, ISBN 015101079X, pg. 60:They say feed a cold, starve a fever, but they don't tell you what to do when you got both, so I figured scrambled eggs, tea, and toast.
