“…The present experiments established for the first time that the entry of normal amounts of readily utilized carbohydrate into the circulation by the physiological route is followed by an inhibition of feeding, and that this post-absorptive inhibition can be sufficiently strong to explain much of normal satiation. Suppression of feeding by gastrointestinal or systemic administration of nutrient has hitherto often been attributed to colligative or bulk effects (Janowitz & Grossman, 1948McCleary, 1953;Smith & Duffy;1957;Smith, 1966;Yin, Hamilton & Brobeck, 1970;Baile, Zinn & Mayer, 1971;Ehman, Albert & Jamieson, 1971;Yin & Tsai, 1973). Such conclusions depend on experiments which have been run under inappropriate conditions.…”

SUMMARY1. Solutions of glucose or other carbohydrates were administered during the dark or light period of the circadian cycle to rats which had been only briefly deprived of food.2. Food was restored to the animals at various times after administration of a glucose load by stomach tube. With delays between loading and access to food of up to 3 hr by night and 2 hr by day, subsequent food intake was less than intake after non-nutritive loads.3. Measurement of the glucose content of the gastrointestinal tract at various times after glucose loading showed that this depression of intake was still apparent even when the rat was offered food some time after complete absorption of the stomach load.4. Infusion of a glucose solution into the duodenum or the hepatic portal vein also inhibited subsequent food intake.5. In all cases, the inhibition of food intake was expressed as a decrease in the size of the first meal after restoring access to food.6. These results provide the first demonstration that the entry of normal amounts of carbohydrate into the body by the physiological route is followed by a depression of food intake which lasts until after absorption is complete.

“…Indeed, a purely osmotic theory of glucose-induced satiety was advocated because of the observation that an intragastric load of 1 M glucose can produce a decrease in food intake over the subsequent 1 and 2 hr. in 22hr, food-deprived rats which is similar to that produced by an equal volume of equiosmolar sodium chloride (Smith, 1966;Smith & Duffy, 1957;Smith, Pool, & Weinberg, 1959;Smith, Salisbury, & Weinberg, 1961). However, it was known that drinking for 1-2 hr.…”

Glucose solutions were administered intragastrically to rats having free access to food except during the first hour after intubation. The distribution of meals after intubation indicated that effects of glucose both prolong satiety and contribute to its initiation, during the dark or the bright phase of the lighting cycle. From about 5 hr. after intubation and from the start of the second meal, the net cumulative inhibition of food intake amounted to apparently close to exact caloric compensation for the glucose load. Feeding was not differentially inhibited by control loads of the same volume as the glucose load, whether the control was air, water, sodium chloride, urea, or 3-methylglucose. The results provide the first demonstration in support of a theory of short-term behavioral regulation according to an energostatic signal generated from glucose.

“…This is demonstrated by the continuous feeding patterns of Group 40. In support of the oral limit idea , only extremely large gastric preloads of nonnutritive bulk were found to suppress subsequent intake during a scheduled feed (Smith & Duffy , 1957). At the oral level, the bulk measure kcal /rnl, is likely to be a critical property .…”

“…The analysis of meal patterns in freely feeding rats has led to considerable advances in our understanding of the substrates for eating behavior (LeMagnen, Devos, GaudiIliere, Louis-Sylvestre, & Tallon, 1973). Relatively little attention has been paid to events occurring within brief access times (Ghent, 1957;LeMagnen, 1967;Skinner, 1930;Smith & Duffy, 1957). In particular, no systematic study of possible interactions between access time, palatability, caloric density, and adaptation to the schedule, has been performed.…”
