The long-term effect of energy intake on salivation, hunger, and appetite ratings, and estimates of energy intake in obese patients.
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.
