Visceral Feedback and the Taste Signal

Visceral feedback after eating a meal modifies the taste of the food and drink by psychological processes which are of special interest to students of biofeedback. For simplicity, consider an unlimited amount of a tasty fluid placed before a hungry subject. The taste of the fluid is the perceptual signal, ingestion is the process to be controlled and homeostatic well-being is the state to be achieved. If the fluid is a creamy substance, rich in calories, it tastes delicious at the beginning of the meal and the subject drinks heartily. As the caloric mass accumulates in the gut, satiety is achieved before tissue needs are redressed, as if the viscera has sensing devices which accurately estimate the amount of food needed to achieve the ultimate homeostatic balance (Novin, 1976; Schachter, 1971; McHugh, Moran, & Barton, 1975).
