Relationships Between Body Image and Body Parameters in Men Under Long-Term Fasting Conditions

<b>Background/Objectives</b>: Fasting and physical exertion positively affect body mass and composition. This study aimed to examine the effects of physical changes induced by eight days of water-only fasting and a physical exertion test and their influence on body satisfaction and body image parameters in middle-aged men. <b>Methods</b>: Fifteen participants were assessed for physical (height, body mass, and body composition) and psychological (body satisfaction, evaluation of body parts, and body image determinants) aspects before and after the fasting intervention, both at rest and post-exercise. Correlation and concordance coefficients were calculated for the analyzed variables. <b>Results</b>: It was found that the fasting intervention led to a reduction in body mass and a favorable shift in body composition, while also increasing satisfaction with one's body and its specific parts. This positively impacted volunteers' self-assessment of their health status. Selected body image parameters remained at an average level for the male population and did not change following the fasting. Attitudes toward body weight control methods and their perceived effectiveness did not change either. Participants favored reducing food intake and eliminating high-calorie products from their diet, rejecting the use pathological methods typically associated with eating disorders. A few associations between physical and psychological aspects of corporeality were observed, whereas significant correlations between satisfaction with body parts and parameters and a positive body image were confirmed. <b>Conclusions</b>: The above suggest that physical conditions and their changes resulting from fasting and physical exertion lead to a positive influence on body satisfaction and its components but do not alter body image.
