The Effects of Starvation on Behavior: Implications for Dieting and Eating Disorders. One of the most important advances in the understanding of eating disorders is the recognition that severe and prolonged dietary restriction can lead to serious physical and psychological complications. Many of the symptoms once thought to be primary features of anorexia nervosa are actually symptoms of starvation. Given what we know about the biology of weight regulation, what is the impact of weight suppression on the individual? This question is particularly relevant for health professionals who treat eating disorders, but is also important in obesity treatment, for dieters, and for others who have lost significant amounts of body weight. Perhaps the most powerful illustration of the effects of restrictive dieting and weight loss on behavior is an experimental study conducted over 5. Ancel Keys and his colleagues at the University of Minnesota. The experiment involved carefully studying 3. More than 1. 00 men volunteered for the study as an alternative to military service; the 3. What makes the “starvation study,” as it is commonly known, so important is that many of the experiences observed in the volunteers are the same as those experienced by patients with eating disorders as well as some people who have undergone weight loss programs. During the first 3 months of the semistarvation experiment, the volunteers ate normally while their behavior, personality, and eating patterns were studied in detail. During the next 6 months, the men were restricted to approximately half of their former food intake and lost, on average, approximately 2. Although this was described as a study of “semistarvation,” it is important to keep in mind that cutting the men’s rations to half of their formerintake (to an average of 1,5. The 6 months of weight loss were followed by 3 months of rehabilitation, during which the men were gradually refed. A subgroup was followed for almost 9 months after the refeeding began. Most of the results were reported for only 3. Although the individual responses to weight loss varied considerably, the men experienced dramatic physical, psychological, and social changes. Nutrition basics for fat loss, muscle gain, and strength broken into steps as the body continues to adapt to changing diet; with sample meal plans.In most cases, these changes persisted during the rehabilitation or renourishment phase. Attitudes and behavior related to food and eating. One of the most striking changes that occurred in the volunteers was a dramatic increase in food preoccupation. The men found concentration on their usual activities increasingly difficult, because they became plagued by incessant thoughts of food and eating. During the semistarvation phase of the experiment, food became a principal topic of conversation, reading, and daydreams. Rating scales revealed that the men experienced increase in thoughts about food, as well as corresponding decreases in interest in sex and activity during semistarvation. The actual words used in the original report are particularly revealing and the following quotations followed by page numbers in parentheses are from Keys et a. They made what under normal conditions would be weird and distasteful concoctions, (p. According to the original report, hoarding even extended to nonfood- related items such as “old books, unnecessary second- hand clothes, knick knacks, and other . Often after making such purchases, which could be afforded only with sacrifice, the men would be puzzled as to why they had bought such more or less useless articles” (p. One man even began rummaging through garbage cans. This general tendency to hoard has been observed in starved anorexic’ patients and even in rats deprived of food. Despite little interest in culinary matters prior to the experiment, almost 4. For some, the fascination was so great that they actually changed occupations after the experiment; three became chefs! The Minnesota subjects often were caught between conflicting desires to gulp their food down ravenously and consume it slowly so that the taste and odor of each morsel would be fully appreciated. They did much planning as to how they would handle their day’s allotment of food (p. The men demanded that their food be served hot, and they made unusual concoctions by mixing foods together, as noted above. There also was a marked increase in the use of salt and spices. The consumption of coffee and tea increased so dramatically that the men had to be limited to nine cups per day; similarly, gum chewing became excessive and had to be limited after it was discovered that one man was chewing as many as 4. During the 1. 2- week refeeding phase of the experiment, most of the abnormal attitudes and behaviors related to food persisted. Binge eating. During the restrictive dieting phase of the experiment, all of the volunteers reported increased hunger. Some appeared able to tolerate the experience fairly well, but for others it created intense concern and led to a complete breakdown in control. Several men were unable to adhere to their diets and reported episodes of binge eating followed by self- reproach. During the eighth week of starvation, one volunteer flagrantly broke the dietary rules, eating several sundaes and malted milks; he even stole some penny candies. He promptly confessed the whole episode, . While working in a grocery store, another man suffered a complete loss of will power and ate several cookies, a sack of popcorn, and two overripe bananas before he could regain control of himself. He immediately suffered a severe emotional upset, with nausea, and upon returning to the laboratory he vomited . One man was released from the experiment at the end of the semistarvation period because of suspicions that he was unable to adhere to the diet. He experienced serious difficulties when confronted with unlimited access to food: “He repeatedly went through the cycle of eating tremendous quantities of food, becoming sick, and then starting all over again” (p. During the refeeding phase of the experiment, many of the men lost control of their appetites and “ate more or less continuously” (p. Even after 1. 2 weeks of refeeding, the men frequently complained of increased hunger immediately following a large meal.“. One man required aspiration and hospitalization for several days, (p. Their daily intake commonly ranged between 8,0. Subject No. 2. 0 stuffs himself until he is bursting at the seams, to the point of being nearly sick and still feels hungry; No. No. 1 ate until he was uncomfortably full; and subject No. After about 5 months of refeeding, the majority of the men reported some normalization of their eating patterns, but for some the extreme overconsumption persisted “No. More than 8 months after renourishment began, most men had returned to normal eating patterns; however, a few were still eating abnormal amounts. Factors distinguishing men who rapidly normalized their eating from those who continued to eat prodigious amounts were not identified. Nevertheless, the main findings here are as follows: Serious binge eating developed in a subgroup of men, and this tendency persisted in some cases for months after free access to food was reintroduced; however, the majority of men reported gradually returning to eating normal amounts of food after about 5 months of refeeding.

The Effects of Starvation on Behavior: Implications for Dieting and Eating Disorders. One of the most important advances in the understanding of eating disorders is. Thus, the fact thatbinge eating was experimentally produced in some of these normal young men should temper speculations about primary psychological disturbances as the cause of binge eating in patients with eating disorders. These findings are supported by a large body of research indicating that habitual dieters display marked overcompensation in eating behavior that is similar to the binge eating observed in eating disorders. Polivy et al. 9. 15- 9. Although the subjects were psychologically healthy prior to the experiment, most experienced significant emotional deterioration as a result of semistarvation. Most subjects experienced periods during which their emotional distress was quite severe; almost 2. Depression became more severe during the course of the experiment. Mood swings were extreme for some of the volunteers. Irritability and frequent outbursts of anger were common, although the men had fairly tolerant dispositions prior to starvation. For most subjects, anxiety became more evident. As the experiment progressed, many of the formerly even- tempered men began biting their nails or smoking because they felt nervous. Apathy also became common, and some men who had been moderately fastidious neglected various aspects of personal hygiene. During semistarvation, two subjects developed disturbances of psychotic proportions. During the refeeding period, emotional disturbance did not vanish immediately but persisted for several weeks, with some men actually becoming more depressed, irritable, argumentative, and negativistic than they had been during semi starvation. After 2 weeks of refeeding, one man reported his extreme reaction in his diary: I have been more depressed than ever in my life . Ten days ago, I jacked up my car and let the car fall on these fingers . Several days later, this man actually did chop off three fingers of one hand in response to the stress. Standardized personality testing with the Minnesota Multiphasic Personality Inventory (MMPI) revealed that semistarvation resulted in significant increases on the Depression, Hysteria, and Hypochondriasis scales. The MMPI profiles for a small minority of subjects confirmed the clinical impression of incredible deterioration as a result of semistarvation. One man scored well within normal limits at initial testing, but after 1. MMPI. Social and sexual changes. The extraordinary impact of semistarvation was reflected in the social changes experienced by most of the volunteers. Although originally quite gregarious, the men became progressively more withdrawn and isolated. Humor and the sense of comradeship diminished amidst growing feelings of social inadequacy. The volunteers’ social contacts with women also declined sharply during semistarvation.
