title: The long-term effect of energy intake on salivation, hunger, and appetite ratings, and estimates of energy intake in obese patients.
abstract: The relationship between salivation, hunger, appetite, and estimates of energy intake was examined in female obese inpatients undergoing a course of weight reduction. On a constant low-energy intake (800 kcal/day) salivation, hunger, and appetite scores all declined. Estimates of energy intake did not. Sixteen different subjects were fed 1000 kcal/day for seven days, 500 kcal/day for seven days, and 1000 kcal/day for seven days. After acclimatization to the diet for a minimum of five days, salivation was directly related to energy intake; hunger and appetite ratings did not change significantly; and estimates of energy intake were sensitive to the decrease but not increase in energy intake. The limitations of each method of assessment are discussed.
