Choosing Health: acceptability and feasibility of a theory-based, online-delivered, tailored weight loss, and weight loss maintenance intervention.

Few weight loss and weight loss maintenance interventions are tailored to include factors demonstrated to predict the user's behavior. Establishing the feasibility and acceptability of such interventions is crucial. The aim of this study was to assess the acceptability and feasibility of a theory-based, tailored, online-delivered weight loss and weight loss maintenance intervention (Choosing Health).

Developing the "Choosing Health" Digital Weight Loss and Maintenance Intervention: Intervention Mapping Study.

Background: Digital health promotion programs tailored to the individual are a potential cost-effective and scalable solution to enable self-management and provide support to people with excess body weight. However, solutions that are widely accessible, personalized, and theory- and evidence-based are still limited.

Objective: This study aimed to develop a digital behavior change program, Choosing Health, that could identify modifiable predictors of weight loss and maintenance for each individual and use these to provide tailored support.

Theory-based digital intervention to promote weight loss and weight loss maintenance (Choosing Health): protocol for a randomised controlled trial.

Introduction: Digital behavioural weight loss interventions have the potential to improve public health; however, these interventions are often not adequately tailored to the needs of the participants. This is the protocol for a trial that aims to determine the effectiveness and cost-effectiveness of the programme as a means to promote weight loss and weight loss maintenance among overweight/obese adults.

Methods And Analysis: The proposed study is a two-group randomised controlled trial with a nested interrupted time series (ITS) within-person design.

Food neophobia in children.

Eating habits are formed from the early childhood through experience gained from the contact with foods and as a result of observation of the environment. One of the feeding disorders, specific for the childhood, is food neophobia, defined as an attitude towards food, which manifests as a persistent reluctance to eat new foods, avoiding tasting unknown products and unwillingness to accept newly in-troduced flavours or unknown consistency of food. It should be differentiated from pickiness, which are a typical stage of children's development.

At-home environment, out-of-home environment, snacks and sweetened beverages intake in preadolescence, early and mid-adolescence: the interplay between environment and self-regulation.

Obesity-related behaviors, such as intake of snacks and sweetened beverages (SSB), are assumed to result from the interplay between environmental factors and adolescents' ability to self-regulate their eating behaviors. The empirical evidence supporting this assumption is missing. This study investigated the relationships between perceptions of at-home and out-of-home food environment (including SSB accessibility, parental, and peers' social pressure to reduce intake of SSB), nutrition self-regulatory strategies (controlling temptations and suppression), and SSB intake.
