“…We chose to focus on users with underweight BMI goals because this desire to be underweight can signal unhealthy behaviors. Having an underweight BMI goal does not mean that all of these users have clinical eating disorders; rather the intent to be underweight and wanting to lose weight when already at a healthy weight or underweight could be indicative of disordered eating behaviors [21,22]. Additionally, BMI under 18.5 is a potential marker of anorexia nervosa.…”

“…Setting unhealthily low BMI goals signals a desire to be underweight and a drive for thinness, which are associated with disordered eating behaviors and eating disorders [21,22]. Drive for thinness “is characteristic of individuals with fear of weight gain who diet to prevent it, but also of those who seek to attain an unhealthily low body weight as seen in many individuals with anorexia nervosa or bulimia nervosa” [22].…”

BackgroundMobile health (mHealth) apps for weight loss (weight loss apps) can be useful diet and exercise tools for individuals in need of losing weight. Most studies view weight loss app users as these types of individuals, but not all users have the same needs. In fact, users with disordered eating behaviors who desire to be underweight are also utilizing weight loss apps; however, few studies give a sense of the prevalence of these users in weight loss app communities and their perceptions of weight loss apps in relation to disordered eating behaviors.ObjectiveThe aim of this study was to provide an analysis of users’ body mass indices (BMIs) in a weight loss app community and examples of how users with underweight BMI goals perceive the impact of the app on disordered eating behaviors.MethodsWe focused on two aspects of a weight loss app (DropPounds): profile data and forum posts, and we moved from a broader picture of the community to a narrower focus on users’ perceptions. We analyzed profile data to better understand the goal BMIs of all users, highlighting the prevalence of users with underweight BMI goals. Then we explored how users with a desire to be underweight discussed the weight loss app’s impact on disordered eating behaviors.ResultsWe found three main results: (1) no user (regardless of start BMI) starts with a weight gain goal, and most users want to lose weight; (2) 6.78% (1261/18,601) of the community want to be underweight, and most identify as female; (3) users with underweight BMI goals tend to view the app as positive, especially for reducing bingeing; however, some acknowledge its role in exacerbating disordered eating behaviors.ConclusionsThese findings are important for our understanding of the different types of users who utilize weight loss apps, the perceptions of weight loss apps related to disordered eating, and how weight loss apps may impact users with a desire to be underweight. Whereas these users had underweight goals, they often view the app as helpful in reducing disordered eating behaviors, which led to additional questions. Therefore, future research is needed.

“…The Drive for Thinness Scale is a 7-item scale that assesses “an extreme desire to be thinner, preoccupation with weight, and an intense fear of weight gain” (p. 14, 55). Extensive reliability, construct, and predictive validity have been established (56, 57). The internal consistency of this scale in our scale was .95.…”

The Clinical Significance of Posterior Insular Volume in Adolescent Anorexia Nervosa

Objective The diagnostic criterion disturbance in the experience of the body remains a poorly understood and persistent feature of anorexia nervosa (AN). Increased sophistication in understanding the structure of the insular cortex - a neural structure that receives and integrates visceral sensations with action and meaning - may elucidate the nature of this disturbance. We explored age, weight-status, illness severity, and self-reported body dissatisfaction associations with insular cortex volume. Methods Structural MRI data were collected from 21 adolescents with a history of AN and 20 age, sex, and BMI-matched controls. Insular cortical volumes (bilateral anterior and posterior regions) were identified using manual tracing. Results Volumes of the right posterior insula demonstrated: 1) a significant age by clinical status interaction (β = −0.018 ± 0.008; t = 2.32, p = 0.02) and 2) larger volumes were associated with longer duration of illness (r = .48, p < .04). In contrast, smaller volumes of the right anterior insula were associated with longer duration of illness (r = −.50, p < .03). The associations of insular volume with body dissatisfaction were of moderate effect size, also of opposite direction, but a statistical trend in right posterior (r = .40, p < .10 in right posterior; r = −.49, p < .04 in right anterior). Conclusions In this exploratory study, findings of atypical structure of the right posterior insular cortex point to the importance of future work investigating the role of visceral afferent signaling in understanding disturbance in body experience in AN.

“…Drive for thinness is characteristic of individuals who have a high fear of weight gain and consequently diet to prevent it, such as those with AN and BN (Chernyak & Lowe, 2010; Penas-Lledo, Bulik, Lichtenstein, Larsson, & Baker, 2015). Ramacciotti and colleagues (2002) found that individuals with AN or BN with a low drive for thinness reported less severe eating disorder-related psychopathology than those with a high drive for thinness, highlighting how drive for thinness may be an indicator of future relapses.…”

Fear of food prospectively predicts drive for thinness in an eating disorder sample recently discharged from intensive treatment

Fears of food are common in individuals with eating disorders and contribute to the high relapse rates. However, it is unknown how fears of food contribute to eating disorder symptoms across time, potentially contributing to an increased likelihood of relapse. Participants diagnosed with an eating disorder (N = 168) who had recently completed intensive treatment were assessed after discharge and one month later regarding fear of food, eating disorder symptoms, anxiety sensitivity, and negative affect. Cross lagged path analysis was utilized to determine if fear of food predicted subsequent eating disorder symptoms one month later. Fear of food—specifically, anxiety about eating and feared concerns about eating—predicted drive for thinness, a core symptom domain of eating disorders. These relationships held while accounting for anxiety sensitivity and negative affect. There is a specific, direct relationship between anxiety about eating and feared concerns about eating and drive for thinness. Future research should test if interventions designed to target fear of food can decrease drive for thinness and thereby prevent relapse.
