Outcome in anorexia nervosa remains poor and a new way of looking at this condition is therefore needed. To this aim, we review the effects of food restriction and starvation in humans. It is suggested that body weight remains stable and relatively low when the access to food requires a considerable amount of physical activity. In this condition, the human(More)
Women were divided into those eating at a decelerated or linear rate. Eating rate was then experimentally increased or decreased by asking the women to adapt their rate of eating to curves presented on a computer screen and the effect on food intake and satiety was studied. Decelerated eaters were unable to eat at an increased rate, but ate the same amount(More)
We determined whether women and men would alter their pattern of food intake after they had deprived themselves of food. We found that women consumed 12% less food after fasting and that men ate 28% more food after fasting. Serving more food on the test day did not increase food intake of women. Women, who ate at a nearly constant rate (linear eaters),(More)
We report the results of a study based on 1,428 patients with eating disorders treated at 6 clinics. These patients were consecutively referred over 18 years and used inpatient and outpatient treatment. The subjects were diagnosed with anorexia nervosa, bulimia nervosa, or an eating disorder not otherwise specified. Patients practiced a normal eating(More)

We hypothesize that the changes in mood that are associated with eating disorders are caused by a change in eating behavior. When food is in short supply, the rhythm of the neural network for eating, including orbitofrontal(More)
The world-wide increase in obesity has markedly stimulated research on the possibility that its cause can be found the brain. However, this research has produced little that can be used to treat obesity. The reason for the limited success of this approach may be that it relies on the hypothesis that the brain controls behavior. We suggest that this(More)
The hypothesis that eating disorders are caused by an antecedent mental disorder, presently believed to be an obsessive compulsive disorder, has been clinically implemented during many years but has not improved treatment outcome. Alternatively, eating disorders are eating disorders and the symptoms of anorexic patients and probably bulimic patients as(More)
A method for the control of eating rate gave subjects feedback from a computer screen on how much and at what rate to eat during a meal. The method also allowed us to record the development of satiety during the meal. Linear eaters--that is, women selected for eating at an approximately constant rate--underate when challenged to eat at a lower rate and(More)
A wealth of data supports the idea that the stomach and cholecystokinin octapeptide (CCK-8) normally play important roles in meal size and satiety. We studied long-term gastrectomized humans to further evaluate this possibility. Ten humans, who were gastrectomized 8 (3-12) years earlier, and eight controls ate a meal from a plate placed on a scale connected(More)
We have suggested that reduced food intake increases the risk for anorexia nervosa by engaging mesolimbic dopamine neurons, thereby initially rewarding dieting. Recent fMRI studies have confirmed that dopamine neurons are activated in anorexia nervosa, but it is not clear whether this response is due to the disorder or to its resulting nutritional deficit.(More)
