This study examined the body weight and waist-to-hip ratio (WHR) preferences of “fat admirers” (FAs), that is, individuals who are sexually attracted to heavier partners. Fifty-six heterosexual men involved in the FA community rated a series of line drawings that varied in three levels of body weight and six of WHR for physical attractiveness and health. The results showed significant main effects of body weight and WHR, as well as a significant body weight × WHR interaction for both health ratings. In general, there was a preference for heavyweight figures and high WHRs for ratings of attractiveness and normal-weight figures and mid-ranging WHRs for ratings of health. Limitations of the study and explanations for fat admiration are discussed.

This study reports results from the first International Body Project (IBP-I), which surveyed 7,434 individuals in 10 major world regions about body weight ideals and body dissatisfaction. Participants completed the female Contour Drawing Figure Rating Scale (CDFRS) and self-reported their exposure to Western and local media. Results indicated there were significant cross-regional differences in the ideal female figure and body dissatisfaction, but effect sizes were small across high-socioeconomic-status (SES) sites. Within cultures, heavier bodies were preferred in low-SES sites compared to high-SES sites in Malaysia and South Africa (ds = 1.94-2.49) but not in Austria. Participant age, body mass index (BMI), and Western media exposure predicted body weight ideals. BMI and Western media exposure predicted body dissatisfaction among women. Our results show that body dissatisfaction and desire for thinness is commonplace in high-SES settings across world regions, highlighting the need for international attention to this problem.

Distress can have a profoundly negative impact on the well-being of women (who are the main receivers of treatment for distress). Distress also poses a huge financial problem for the United Kingdom, the cost of which is predicted to reach over £26bn by 2026. A growing body of research has shown that various medicinal plants have potential to treat different aspects of distress. However, there is little research investigating the patient experience of western herbal practice (WHP), and none investigating women’s experiences of WHP for distress. In response, this longitudinal study utilised interviews with twenty-six women who were visiting herbalists for distress across the south-east of The United Kingdom to elicit their stories of distress, as well as their experiences of WHP. The narratives were analysed from a constructionist standpoint, using inductive thematic analysis. The participants’ narratives highlighted the profound impact of everyday distress, whilst feelings associated with distress (anxiety, low mood, isolation, shame and guilt) were frequently communicated via the use of metaphors. These negative feelings, often combined with unsuccessful biomedical encounters, frequently led to the women feeling desperate when first visiting a herbalist. The participants’ experiences of WHP showed that an accessible practitioner and good therapeutic relationship combined with flexible herbal treatment, allowed women with diverse stories of distress to overcome feelings of desperation. Ongoing support allowed the women to feel like they had a safety net as they journeyed from a place of distress, back into the wider world. These findings were supported by more unusual negative accounts, which showed how the herbal therapeutic process could be unsuccessful if elements were missing. This research is of significance as it helps to deepen our understanding of women’s experiences of distress – particularly perceptions of stigma which surround feelings of shame (linked to an inability to cope) and guilt (linked to the perceived impact of distress on others). The research also has relevance for WHP, as it highlights which positive aspects of WHP are of particular importance to women patients who are living with distress.

Introduction Quantitative and accurate measurements of fat and muscle in the body are important for prevention and diagnosis of diseases related to obesity and muscle degeneration. Manually segmenting muscle and fat compartments in MR body-images is laborious and time-consuming, hindering implementation in large cohorts. In the present study, the feasibility and success-rate of a Dixon-based MR scan followed by an intensity-normalised, non-rigid, multi-atlas based segmentation was investigated in a cohort of 3,000 subjects. Materials and Methods 3,000 participants in the in-depth phenotyping arm of the UK Biobank imaging study underwent a comprehensive MR examination. All subjects were scanned using a 1.5 T MR-scanner with the dual-echo Dixon Vibe protocol, covering neck to knees. Subjects were scanned with six slabs in supine position, without localizer. Automated body composition analysis was performed using the AMRA Profiler™ system, to segment and quantify visceral adipose tissue (VAT), abdominal subcutaneous adipose tissue (ASAT) and thigh muscles. Technical quality assurance was performed and a standard set of acceptance/rejection criteria was established. Descriptive statistics were calculated for all volume measurements and quality assurance metrics. Results Of the 3,000 subjects, 2,995 (99.83%) were analysable for body fat, 2,828 (94.27%) were analysable when body fat and one thigh was included, and 2,775 (92.50%) were fully analysable for body fat and both thigh muscles. Reasons for not being able to analyse datasets were mainly due to missing slabs in the acquisition, or patient positioned so that large parts of the volume was outside of the field-of-view. Discussion and Conclusions In conclusion, this study showed that the rapid UK Biobank MR-protocol was well tolerated by most subjects and sufficiently robust to achieve very high success-rate for body composition analysis. This research has been conducted using the UK Biobank Resource.
