Objective: The purpose of the present study was to develop and assess the construct validity of a tool to measure knowledge, attitudes and practices of registered dietitians/nutritionists (RD/N) regarding an intuitive eating lifestyle.
Design: Cross-sectional study design that utilized a survey administered to a random sample and remaining full population of RD/N.
Setting: A national survey conducted via online survey software.
Subjects: A random sample of 10 % of all RD/N in the USA (n 8834) was invited to participate. Survey completion rate was 22·2 % (n 1897). After initial validation, the survey was distributed to the remaining 90 % of RD/N to confirm validation.
Results: After removing items with insufficient factor loadings, results were consistent with a four-factor solution: (i) knowledge of intuitive eating; (ii) attitudes towards intuitive eating; (iii) traditional and restrictive practices; and (iv) non-restrictive and intuitive eating practices. Confirmatory factor analysis provided further evidence of the validity of the four factors and the factors had strong reliability.
Conclusions: Unlike the hypothesized three-factor solution (knowledge, attitudes and practices), validation analysis revealed that the survey measures knowledge of intuitive eating, attitudes towards intuitive eating, use of traditional and restrictive weight-management practices, and use of non-restrictive and intuitive eating practices. With the landscape of weight management and health promotion undergoing a shift towards a health centred, size acceptance approach, this instrument will provide valuable information regarding the current knowledge, attitudes and practices of RD/N and other health promotion professionals.

Background: Appetite-regulating hormones are implicated in anorexia nervosa (AN) pathophysiology, however, data are limited for appetite-regulating hormones across the AN weight spectrum. We aimed to investigate fasting and post-prandial concentrations of appetite-regulating hormones - peptide YY (PYY), cholecystokinin (CCK), and ghrelin - among adolescent and young adult females across the AN weight spectrum, specifically those with AN and Atypical AN, and healthy controls (HC).
Methods: Participants (N = 95; ages 11-22 years) included 33 with AN, 25 with Atypical AN, and 37 HC.
Weight bias internalization statistically mediates the association between positive body image and intuitive eating: A cross-sectional study.

Fort Lauderdale, Florida. At the time this work began, S. Rothenberg was a graduate student at Nova Southeastern University.
Background: Two facets of positive body image, body appreciation and functionality appreciation, are positively associated with an adaptive eating style known as intuitive eating. Little is known about the mechanisms underlying the association between positive body image and intuitive eating, although it is well established that weight bias internalization is associated with unfavorable views of the self and body and interferes with health behavior engagement.
Objective: The present cross-sectional study examined weight bias internalization as a statistical mediator of the association between positive body image (i.
Intuitive eating predictors and outcomes in people with severe mental illness participating in a lifestyle intervention.

Addiction and Mental Health Service, Metro South Health, Brisbane, Australia.
Issue Addressed: People with severe mental illness (SMI) are at higher risk of preventable diseases than the general population; poor diet contributes to heightened risk. Adaptive approaches designed to improve intuitive eating may improve dietary behaviours in people with SMI. Aims of this study were to investigate predictors of, and assess the impact of a nutrition program on, intuitive eating in people with SMI.

Background/objectives: Obesity among college students has been consistently high in the recent decades. Regulatory processes such as interoception and self-regulation have been studied to identify specific health behaviors that lead to weight gain. Reduced interoception and self-regulation may lead to increased body mass index (BMI), however, various eating styles may indirectly affect this relationship.

Article Synopsis
- - The study investigates the challenges faced by Mexican immigrant farmworkers regarding access to health services and the prevalence of diet-related health issues, highlighting the need for culturally sensitive health interventions.
- - Researchers developed a mobile app for a 14-day dietary assessment using food photography, aiming to gather data on the participants' eating habits while accommodating low literacy levels.
- - Results from 16 participants showed a total of 1475 food photos taken, with a slight decrease in daily photo counts from the first week to the second, indicating trends in adherence to the protocol.
