The story of the word

For Hippocratic doctors δίαιτα covered a patient's whole life: food, drink, exercise, sleep, sex, climate, the house they lived in. Prescribing a diet meant prescribing a routine, and the narrowing to what goes in the mouth took centuries. The slimming sense is nineteenth-century. The parliamentary Diet, as at Worms in 1521, is a different word, from Medieval Latin dieta, a day's assembly.
