The emotional consequences of excessive body mass, associated with body image and acceptance, have become a global public health challenge as they may decrease the general well-being and hinder weight loss in overweight and obese individuals. Therefore, this study aimed to analyze the influence of age, body mass index (BMI), and waist-to-height ratio (WHtR) on body mass acceptance, attitudes, and motivation toward body mass reduction in overweight and obese Caucasian women with excessive abdominal fat. The previously validated BodyMass–DRama (Body Mass–Dietary Restrictions: Acceptance, Motivation, Attitudes) questionnaire was applied in this study. The declared acceptance, attitudes and motivation towards body mass reduction were compared between subgroups based on age (20–40, 40–50, and 50–60 years), BMI (25.0–30.0, 30.0–35.0, and ≥35.0 kg/m2), and quartiles of WHtR. The age, BMI and WHtR were stated to be associated with declared acceptance, attitudes, and motivation towards body mass reduction. The different age groups indicated the following as the reasons for excessive body mass: young respondents—low physical activity and consumption of sweets; middle-aged ones—large/irregular meals; aging ones—large/irregular meals and low physical activity (p = 0.0161). While describing motivation toward body mass reduction, young respondents indicated the role of a physician or dietitian (p = 0.0012) or someone who can control them (p = 0.0044), as well as their expectation to be more successful at work after body mass reduction (p = 0.0045), while the aging ones indicated appreciation and plaudits from others (p = 0.0264) as a motivating factor. Respondents with the highest BMI declared having spending free time actively constricted (p = 0.0007); they declared more often than others of feeling exhausted (p = 0.0395) or tired all the time (p = 0.0445), but less often of feeling full of joy (p = 0.0457) or full of energy (p <0.0001). Respondents with moderate WHtR declared less often than others that they expect to enjoy socializing (p = 0.0376), but more often to be able to have a better vacation after body mass reduction (p = 0.0128), while those with the lowest WHtR expected to be more physically active (p = 0.0487). Women with the highest WHtR most commonly indicated external pressure from relatives or co-workers as a motivating factor for body mass reduction (p = 0.0435). Due to these differences between Caucasian women with excessive body mass, the approach of physicians and dietitians, as well as methods applied to motivate patients, need to be customized.
