Cluster-analytic studies of clinical populations of eating disordered women who binge eat have yielded two subtypes--pure dietary restraint and mixed dietary restraint-negative affect--consistent with etiologic and maintenance models of binge eating. This study aimed to replicate this subtyping scheme in university women. The scores of 623 undergrad females on the TFEQ-restraint and BDI scales were submitted to a cluster analysis and revealed three subtypes, "healthy" (47.4%), restrained (36.3%) and mixed (16.3%). In addition, comparisons between subtypes on bulimic behaviors showed that the mixed and restrained subtypes were characterized by greater likelihood than the healthy group to engage in fasting, purging and exercise to control weight, as well as in disinhibition of eating. The mixed subtype revealed higher scores than the restrained subtype on eating disinhibition and purging, and the restrained group was more likely than the mixed subtype to exercise to control weight. These findings provide further support for the reliability and validity of this subtyping scheme, in which the confluence of even mild levels of negative affect and dietary restraint differentiated a more "disturbed" group of undergraduate females. Findings also put into question the dietary restraint theory of eating pathology and suggest the need to control negative affect when studying eating behavior.

Experiencing Food Restrictions for Health and Weight Control in Childhood and Their Links to Restrained Eating and Excessive Body Weight in Polish Young Adults-A Cross-Sectional Study.
Nutrients
December 2024
Institute of Human Nutrition Sciences, Warsaw University of Life Sciences (SGGW-WULS), Nowoursynowska 159 C, 02-776 Warsaw, Poland.
Objectives: A better understanding of the conditions leading to overweight and obesity is fundamental due to the ever-increasing phenomenon of excess body weight. This study aimed to determine how the occurrence of restrained eating in young adulthood, food-restricted types, and food experiences related to food restrictions originating in childhood correlate with excessive body weight among young adults.
Methods: The data were collected in Poland in 2020-2021 using a Computer-Assisted Web Interview technique as a cross-sectional study among 358 young adults.
Nutritional Counseling Based on Mindful Eating for the Eating Behavior of People Living with Overweight and Obesity: A Randomized Clinical Trial.
Nutrients

Graduate Program in Nutritional Sciences, Federal University of Health Sciences of Porto Alegre (UFCSPA),Porto Alegre 90050-170, RS, Brazil.
Objectives: This study aimed to evaluate the effect of a counseling approach based on Mindful Eating on the eating behavior of individuals living with overweight and obesity.
Methods: A 16-week randomized clinical trial was conducted to compare an online group intervention (IG) with individual online nutritional counseling (TAU). Volunteers ( = 61), aged 18 or older with BMI ≥ 25 kg/m, were randomly assigned to the two groups and invited to participate in eight biweekly sessions.
Lutein Maintains Bone Mass In Vitro and In Vivo Against Disuse-Induced Bone Loss in Hindlimb-Unloaded Mice.
Nutrients

Cooperative Major of Advanced Health Science, Tokyo University of Agriculture and Technology, 2-24-16 Naka, Koganei 184-8588, Tokyo, Japan.
Background: Lutein, a carotenoid, exhibits various biological activities such as maintaining the health of the eye, skin, heart, and bone. Recently, we found that lutein has dual roles in suppressing bone resorption and promoting bone formation. In this study, we examined the effects of lutein in a disuse-induced osteoporosis model using hindlimb-unloaded (HLU) mice.

Several groups of neurons in the NTS suppress food intake, including Prlh-expressing neurons (NTS cells). Not only does the artificial activation of NTS cells decrease feeding, but also the expression of Prlh (which encodes the neuropeptide PrRP) and neurotransmission by NTS neurons contributes to the restraint of food intake and body weight, especially in animals fed a high fat diet (HFD). We used animals lacking PrRP receptors GPR10 and/or GRP74 (encoded by Prlhr and Npffr2, respectively) to determine roles for each in the restraint of food intake and body weight by the increased expression of Prlh in NTS neurons (NTS mice) and in response to the anorectic PrRP analog, p52.

This study aimed to examine the relationship between eating behavior, nutritional status and mental health. It is a cross-sectional study conducted on a sample of 360 healthy individuals aged 19-64 years. The General Health Questionnaire (GHQ-12) was used to evaluate mental health and the Three-Factor Eating Scale (TFEQ-R21) was used to assess eating behavior.
