Effects of dynamic and static body weight loss on taste responses.

Effects of body weight (bw) decrease induced by restruction of food intake by 75%, 50% and 25% on responses to 1-hr single bottle gustatory tests with glucose, saccharin, salt and quinine were investigated. Rats fed ad libitum served as controls. Food-restricted rats showed dynamic and static loss of bw, the rate and magnitude being proportional to food intake. With the increase in static bw loss across groups, intake on sweet and salt taste was increased and on bitter taste decreased as compared to controls. Though on rapid dynamic bw loss, progressive increase on sweet and salt taste, and gradual decrease on bitter taste was seen with duration of adaptation, it was not commensurate with magnitude of bw loss. However, on slow loss of bw, taste based intake was proportional to bw loss.
