Food choices, microstructure of ingestive behavior and sensory perceptions after bariatric surgery in women: A cross-sectional study.

Unlabelled: Results regarding the impact of bariatric surgery (BS) on food choices are inconsistent between studies based on self-reported questionnaires, and those using direct measurements. Moreover, the determinants of the modifications of food choices after BS, if any, are still poorly understood. This study compared food choices, food liking, microstructure of ingestive behavior and sensory perceptions between women who had BS in the last 18 months (BS group, n = 19; Roux-en-Y gastric bypass or sleeve gastrectomy) and women with BMI ≥35 kg m (OB group, n = 17) in ecological conditions and explored the associations of food choices with sensory perceptions and food liking.

Sustained improvements in brain health and metabolic markers 24 months following bariatric surgery.

Obesity and its metabolic complications are associated with lower grey matter and white matter densities, whereas weight loss after bariatric surgery leads to an increase in both measures. These increases in grey and white matter density are significantly associated with post-operative weight loss and improvement of the metabolic/inflammatory profiles. While our recent studies demonstrated widespread increases in white matter density 4 and 12 months after bariatric surgery, it is not clear if these changes persist over time.

Bias related to overweight and obesity among French psychiatrists: Results of a national survey.

Background: According to people with a higher weight, physicians are the second most stigmatizing group related to excess weight. As a result of these weight-related biases, the therapeutic relationship with the patient and the quality of care would be negatively affected. In addition, this stigma could negatively impact the clinical practice related to higher weight and avoidance of care.

Orthorexia nervosa tendencies and risk of eating disorders among culinary arts students: A comparative study with dietetics students.

Background: Students pursuing food-related academic fields such as dietetics have higher orthorexia nervosa (ON) tendencies and are at a greater risk of developing eating disorders (EDs). However, there is limited research available on ON tendencies and on the risk of EDs in the culinary arts field, which also revolves around food. The present study explored ON tendencies and the risk of EDs among culinary arts students and compared them with those of dietetics students.

Validity of the Addiction-like Eating Behavior Scale among Patients with Compulsive Eating.

Food addiction (FA) and binge eating disorder (BED) co-occur and share compulsive eating symptoms. When using an FA measure, it is important to evaluate its performance in a population presenting compulsive eating. The study aims to validate the Addiction-like Eating Behavior Scale (AEBS) among a clinical sample characterized by compulsive eating and overweight/obesity and to evaluate its incremental validity over the Yale Food Addiction Scale 2.

Does Insulin Delivery Technology Change Our Relationship with Foods? A Scoping Review.

Automated insulin delivery (AID) systems reduce burden and improve glycemic management for people with type 1 diabetes (PwT1D) by automatically adjusting insulin as a response to measured glucose levels. There is a lack of evidence on AID and nutrition variables such as dietary intake, eating behaviors, and disordered eating. This scoping review aims to provide a summary of the literature regarding AID and nutrition variables and to identify gaps that require further investigation.

Measuring implicit associations between food and body stimuli in anorexia nervosa: a Go/No-Go Association Task.

Purpose: The present study aimed to explore the implicit associations between food and bodily stimuli in patients with anorexia nervosa (AN) and control subjects (HC).

Methods: A Go/No-Go Association Task was administrated to 55 participants (28 AN and 27 HC), using food stimuli (low-calorie food vs. high-calorie food) and body stimuli (underweight vs.

When Eating Intuitively Is Not Always a Positive Response: Using Machine Learning to Better Unravel Eaters Profiles.

Background: The aim of the present study was to identify eaters profiles using the latest advantages of Machine Learning approach to cluster analysis.

Methods: A total of 317 participants completed an online-based survey including self-reported measures of body image dissatisfaction, bulimia, restraint, and intuitive eating. Analyses were conducted in two steps: (a) identifying an optimal number of clusters, and (b) validating the clustering model of eaters profile using a procedure inspired by the Causal Reasoning approach.

Neck circumference is a better correlate of insulin resistance markers than other standard anthropometric indices in patients presenting severe obesity.

Background: Previous studies have demonstrated stronger associations between metabolic alterations and neck circumference (NC) than with body mass index (BMI) or waist circumference (WC). However, most of these studies were performed in individuals presenting overweight or mild obesity.

Objective: To determine which adiposity index among BMI, WC, NC and fat mass (FM) can best predict metabolic alterations in men and women presenting severe obesity.

Sinful Foods: Measuring Implicit Associations Between Food Categories and Moral Attributes in Anorexic, Orthorexic, and Healthy Subjects.

Recently, neurocognitive studies have shown that food categorization is sensitive to both the properties of the food stimuli (e.g., calorie content) and the individual characteristics of subjects (e.

[Psychiatric disorders and bariatric surgery].

PSYCHIATRIC DISORDERS AND BARIATRIC SURGERY Psychiatric disorders are common in people with obesity and their lifetime prevalence is estimated to range from 30 % to 70 %. The most frequently reported disorders are mood and anxiety disorders, attention deficit disorder, and binge eating disorder. These disorders will usually improve after bariatric surgery and do not appear to have a significant negative impact on weight loss.

Food Reward after Bariatric Surgery and Weight Loss Outcomes: An Exploratory Study.

Changes in food preferences after bariatric surgery may alter its effectiveness as a treatment for obesity. We aimed to compare food reward for a comprehensive variety of food categories between patients who received a sleeve gastrectomy (SG) or a Roux-en-Y gastric bypass (RYGB) and to explore whether food reward differs according to weight loss. In this cross-sectional exploratory study, food reward was assessed using the Leeds Food Preference Questionnaire (LFPQ) in patients at 6, 12, or 24 months after SG or RYGB.

Association between Visceral Adiposity Index, Binge Eating Behavior, and Grey Matter Density in Caudal Anterior Cingulate Cortex in Severe Obesity.

Visceral adipose tissue accumulation is an important determinant of metabolic risk and can be estimated by the visceral adiposity index (VAI). Visceral adiposity may impact brain regions involved in eating behavior. We aimed to examine the association between adiposity measurements, binge eating behavior, and grey matter density.

The Impact of Restrictive and Non-restrictive Dietary Weight Loss Interventions on Neurobehavioral Factors Related to Body Weight Control: the Gaps and Challenges.

Purpose Of Review: Restrictive diets, such as low-calorie diets, are difficult to maintain in the long term. For this reason, their popularity has decreased compared to non-restrictive approaches, which instead promote healthy eating strategies. Since both strategies may entail different neurobiological mechanisms, this review will examine the current evidence on the effects of restrictive and non-restrictive interventions on neurobehavioral factors.

A systematic review and meta-analyses of food preference modifications after bariatric surgery.

This systematic review and meta-analyses aimed to synthesize evidence of the link between bariatric surgery and changes in food preferences, considering the method of assessment. MEDLINE, Cochrane Library, Web of Science, Cinahl, PsychINFO, ProQuest, and Open grey were searched incorporating two blocks of terms ("Intervention" and "Food Preferences"). Interventional or observational studies involving patients (BMI ≥ 35 kg m ) with sleeve gastrectomy (SG) or Roux-en-Y Gastric Bypass (RYGB) and a control group were included.

Spontaneous neural activity changes after bariatric surgery: A resting-state fMRI study.

Background: Metabolic disorders associated with obesity could lead to alterations in brain structure and function. Whether these changes can be reversed after weight loss is unclear. Bariatric surgery provides a unique opportunity to address these questions because it induces marked weight loss and metabolic improvements which in turn may impact the brain in a longitudinal fashion.

Cognitive function in binge eating disorder and food addiction: A systematic review and three-level meta-analysis.

Background: An extensive body of recent research has focused on the contribution of cognitive functioning to eating behaviors. In binge eating disorder (BED) and food addiction (FA), the extent of cognitive impairment is still unclear. This study aimed to characterize, among those with BED and FA, neurocognitive functions using performances based on neuropsychological tasks in the context of neutral stimuli in adults.

Evaluation of Dietary Assessment Tools Used in Bariatric Population.

Unlabelled: Severe obesity is associated with major health issues and bariatric surgery is still the only treatment to offer significant and durable weight loss. Assessment of dietary intakes is an important component of the bariatric surgery process.

Objective: To document the dietary assessment tools that have been used with patients targeted for bariatric surgery and patients who had bariatric surgery and explore the extent to which these tools have been validated.

Deciphering the Association Between Hypothalamus-Pituitary-Adrenal Axis Activity and Obesity: A Meta-Analysis.

Objective: Both the cortisol awakening response (CAR; corresponding to the state measurement) and hair cortisol concentration (HCC; corresponding to the trait measurement) are considered reliable markers of hypothalamus-pituitary-adrenal axis activity. Because cortisol has long been associated with adiposity, this systematic review and meta-analysis aims to summarize and compare the literature around CAR and HCC and their association with obesity or fat distribution indices.

Methods: The PubMed, Web of Science (Web of Science Core Collection and Medline), EBSCO Information Services, Embase, and PsycNET databases were searched, and full-text articles investigating the association between CAR or HCC and markers of adiposity in humans were included.

Food Preferences and Their Perceived Changes Before and After Bariatric Surgery: a Cross-sectional Study.

Purpose: Changes in food preferences, taste, and smell following bariatric surgery have been previously described but with inconsistent results. We aimed to describe current food preferences and their perceived changes before and after the surgery. We further compared food preferences between patients with and without taste or smell alterations, before and above 2 years follow-up, and concerning the success or failure of their surgery.

Revision of Mason's procedure (vertical banded gastroplasty) to Roux-en-Y gastric bypass: role of an associated fundectomy in weight loss outcomes.

Background: Vertical banded gastroplasty (VBG) presents a significant rate of long-term complications, and revisions are often necessary. Conversion to Roux-en-Y gastric bypass (RYGB) seems to be preferred, but literature data remain limited.

Objectives: To analyze the indications, safety, results of conversions from VBG to RYGB, and to identify predictive factors of success or failure.

An artificial intelligence-derived tool proposal to ease disordered eating screening in people with obesity.

Purpose: In people with obesity, food addiction (FA) tends to be associated with poorer outcomes. Its diagnosis can be challenging in primary care. Based on the SCOFF example, we aim to determine whether a quicker and simpler screening tool for FA in people with obesity could be developed, using artificial intelligence (machine learning).

Food Addiction and Cognitive Functioning: What Happens in Adolescents?

This study aimed to examine cognitive factors associated to food addiction (FA) symptoms in a non-clinical sample of adolescents. A group of 25 adolescents (12-18 years; Mean age = 15.2 years) with a high level of FA symptoms (two and more) were compared to a control group without FA symptoms ( = 25), matched on sex and age, on four Cambridge Neuropsychological Test Automated Battery (CANTAB) neuropsychological tasks (MT: Multitasking Test; OTS: One Touch Stockings of Cambridge; SST: Stop Signal Task; RVP: Rapid Visual Information Processing).
