Note:
The word ketosis was apparently introduced, somewhat hesitantly, by the American physician Frederick Madison Allen (1879-1964) in "The Role of Fat in Diabetes," American Journal of the Medical Sciences, series 2, vol. 153, no. 3 (March, 1917), p. 335: "The second basis of definition [of acidosis] is that of need and distinctiveness. Diminished alkalinity, increased hydrogen ion concentration, lowering of carbon dioxide, decrease of buffer salts, and (for the symptoms of these changes) acid intoxication—all these terms have definite meanings, and to appropriate the name acidosis for any one of them is merely to create a useless synonym. No other name but acidosis exists for the metabolic process which it denotes. Ketonuria and ketonemia have their accurate place but do not cover the ground. Possibly the word ketosis might be suggested and used for special purposes, but the change of established usage would be difficult and seems unnecessary."
