The Ideal

Body dissatisfaction can be defined as a negative subjective evaluation of one’s body as a whole, or relating to specific aspects of one’s body such as body size, shape, muscularity/muscle tone, and weight. Prior research has found that body dissatisfaction is associated with a number of negative psychological and physiological outcomes. This commentary describes the Western ideal male body, as well as providing a summary of theories of the cause and maintenance of male body dissatisfaction.

Method Of Adjustment

Perception of body size was recorded for 63 university students ( M age = 25.3 yr., 41 women) who estimated their own body size using three methods. Using the method of adjustment, subjects over- or underestimated their body size. A signal-detection analysis indicated that subjects were sensitive to detecting a 4% distortion in body size and that there was no systematic bias for reporting distortion as present or absent. Scores on the adaptive probit estimation task were significantly correlated with values for point of subjective equality and the size judgements with the method of adjustment. Over-all, this experiment demonstrated adaptive probit estimation as a reliable indicator of perceived body size, sensitivity in detecting size distortion, and response bias in making body-size judgements.

We combined virtual reality and multisensory bodily illusion with the aim to characterize and reduce the perceptual (body overestimation) and the cognitive-emotional (body dissatisfaction) components of body image distortion (BID) in anorexia nervosa (AN). For each participant (20 anorexics, 20 healthy controls) we built personalized avatars that reproduced their own body size, shape, and verisimilar increases and losses of their original weight. Body overestimation and dissatisfaction were measured by asking participants to choose the avatar that best resembled their real and ideal body. Results show higher body dissatisfaction in AN, caused by the desire of a thinner body, and no body-size overestimation. Interpersonal multisensory stimulation (IMS) was then applied on the avatar reproducing participant’s perceived body, and on the two avatars which reproduced increases and losses of 15% of it, all presented with a first-person perspective (1PP). Embodiment was stronger after synchronous IMS in both groups, but did not reduce BID in participants with AN. Interestingly, anorexics reported more negative emotions after embodying the fattest avatar, which scaled with symptoms severity. Overall, our findings suggest that the cognitive-emotional, more than the perceptual component of BID is severely altered in AN and that perspective (1PP vs. 3PP) from which a body is evaluated may play a crucial role. Future research and clinical trials might take advantage of virtual reality to reduce the emotional distress related to body dissatisfaction.

Body Sizes

Based on the assumptions of self-discrepancy theory, the present study examined the degree of overweight, weight-related body images, and the relation between these images and body mass index (BMI) among two samples of young people from Curaçao (secondary school students, n = 176; undergraduate students, n = 205). In addition to BMI, participants reported their current, ideal, and most feared body sizes, the thinnest and largest body sizes still acceptable to them, and the body size they considered the healthiest by means of the Contour Drawing Rating Scale. We expected females to show a larger discrepancy between current and ideal body size than males (Hypothesis 1) and that this discrepancy (as an indicator of body dissatisfaction) would be related more strongly to BMI among females than among males (Hypothesis 2). Results yielded support for Hypothesis 1 among secondary school students only. Only in the undergraduate sample, BMI and body dissatisfaction were related, but equally so for males and females. Possible explanations are discussed as well as implications for weight management interventions.

Body Size Perception

<p>perception and dissatisfaction.  Though most research studies focus on adolescence and adulthood, dissatisfaction problems are manifesting themselves at increasingly early ages.  The aim of this study was, therefore, to analyse the most significant findings on body dissatisfaction and body-size perception among children aged 3 to 6 (second cycle of pre-school education).  To this end the Medline, SportDiscus, Scopus, ScienceDirect, Dialnet, ProQuest and EBSCO databases were used, and from which a total of 22 studies were selected in accordance with exclusion criteria such as language, peer review and the objective measurement of the body mass index (BMI) of children.  In terms of levels of dissatisfaction, results vary widely, making it impossible to draw sound conclusions on the nature and prevalence of this variable at these ages.  The main reasons for this include the type of instrument used and the difficulties children had in perceiving their bodies correctly.</p>

Body Size Estimation

Body-size distortion has been considered a central symptom of eating disorders. We studied 35 female eating-disordered patients and 85 controls using a computer-based body-size estimation technique. We have found almost identical linear relationships between body-size distortion and weight:height ratios in both groups. In the clinical group, distortion scores were not correlated with scores on the Eating Attitudes Test or Beck Depression Inventory but were negatively correlated with body dissatisfaction as measured on the Eating Disorder Inventory. These results raise further questions about the role of body-size distortion both as a diagnostic criterion and as a complicating phenomenon in eating disorders.
