The effects of energy content and sweet taste on food consumption in restrained and non-restrained eaters.

To characterize restrained eating behavior, we fed pudding mixtures (preloads) varying in energy content and sweet taste to subjects before measuring their intake of a variety of appetizing foods in a laboratory setting. Twenty-four female subjects were divided into three groups: normal-weight restrained eaters (no. = 8), normal-weight non-restrained eaters (no. = 7), and over-weight restrained eaters (no. = 9). Classification of subjects was based on body mass and restrained eating score. Five preloads varying in energy content (393 or 67 kcal) and type of sweeteners (sucrose or cyclamate) were served 1/2 hour before test meals of assorted hors d'oeuvres. Subjects were not informed of the specific aim of the study, and were instructed to eat until full. Multivariate analysis of variance of repeated measures showed that food intake of all subjects was higher after eating low-energy preloads than after eating high-energy preloads, although subjects did not recognize the effect in self-reports (p less than .01). The energy intake of restrained normal-weight eaters was significantly (p less than .05) lower after eating sweet preloads than after eating non-sweet preloads. Findings suggest that a food-intake control mechanism responds to short-term energy deficits among subjects of varied body mass and restrained eating indexes. J Am Diet Assoc 90:1223-1228, 1990.

Behavioural factors involved in the control of food intake in man.

This paper reviews several psychological models to explain disturbed food intake: the "psychosomatic theory", the "stimulus-binding theory", the "concept of restraint eating", closely related to the "concept of latent obesity", the "set-point-theory" and the "boundary model". All are based on the assumption that there are biological regulating processes of body weight (and with this also of feelings of hunger, appetite and satiation as the determinants of food intake), nevertheless the resulting body weight can be inconsistent with social standards and individual self-concepts. In this case a cognitive control of food intake (dieting behaviour) is activated for weight regulation, which in turn interacts with biological regulatory mechanisms, and as a result leads to specific behavioural dispositions which can be supported by experiments.

Imparied glucose tolerance in long-term lithium-treated patients.

The oral glucose tolerance test (oGTT) was performed twice in patients under long-term lithium treatment. Blood glucose and plasma insulin were determined. The oGTT results were evaluated by three criteria (Köbberling-Creutzfeldt, WHO, and Epidemiological Study Group of the European Diabetes Association) and were compared to two representative reference studies from normal populations. The frequency of impaired glucose tolerance in the patients was three times higher than expected on the basis of the studies on normal populations. The variability of the oGTT curves between the first and second tests as well as the steepness of the time-course of the 'insulinogenic index' suggested mild disturbances of carbohydrate metabolism (mild diabetes) in some of the patients. It is considered unlikely that the impairment of glucose tolerance in the patients was a direct pharmacological effect of lithium salts. The possible role of age, sex, manic-depressive disease, additional medication, and particularly obesity in the effects of long-term lithium treatment on glucose tolerance is discussed. The authors suggest that the oGTT should be carried out periodically in long-term, lithium-treated patients over the age of 40 years in order to detect abnormalities in their carbohydrate metabolism.
