Objective: To identify the core components of digital behaviour change interventions for weight loss maintenance targeting physical activity, in terms of: (i) behaviour change techniques, (ii) mechanisms of action, (iii) modes of delivery, (iv) dose and (v) tailoring/personalization. In addition, the links between these components were investigate...
Article
Objective: Weight regain prevention is a critical public health challenge. Digital behaviour change interventions provide a scalable platform for applying and testing behaviour change theories in this challenging context. This study's goal was to analyse reciprocal effects between psychosocial variables (i.e., needs satisfaction, eating regulation...
Article
Background To date, few digital behavior change interventions for weight loss maintenance focusing on long-term physical activity promotion have used a sound intervention design grounded on a logic model underpinned by behavior change theories. The current study is a secondary analysis of the weight loss maintenance NoHoW trial and investigated put...
Article
At present, it is unclear whether eating behavior traits (EBT) predict objectively measured short‐term energy intake (EI) and longer‐term energy balance as estimated by body mass index (BMI). This systematic review examined the impact of EBT on BMI and laboratory‐based measures of EI in adults ( ≥$$ \ge $$18 years) in any BMI category, excluding se...
Article
Background Fat-free mass (FFM) has been shown to be positively associated with hunger and energy intake, an association mediated by resting metabolic rate (RMR). However, FFM comprises a heterogeneous group of tissues with distinct metabolic rates, and it remains unknown how specific high-metabolic rate organs contribute to the degree of perceived...
Article
Background Up to 30% of community-based older adults report reduced appetite and energy intake (EI), but previous research examining the underlying physiological mechanisms have focused on the mechanisms that suppress eating rather than the hunger drive and EI. Objective To examine the associations between fat-free mass (FFM), physical activity (P...
Article
Introduction: Free-living movement (physical activity [PA] and sedentary behaviour [SB]) and eating behaviours (energy intake [EI] and food choice) affect energy balance and therefore have the potential to influence weight loss (WL). This study explored whether free-living movement and/or eating behaviours measured early (week 3) or late (week 12)...
Article
Overweight and obesity remain serious public health concerns. Outcomes from community based commercial weight management programmes vary, relapse is common and drop out is high. Outcomes could be improved by better understanding experiences on these programmes. The aim of our study was to generate accounts of people’s experience on a commercial wei...

Understanding people's goal content for weight management can contribute to the design of more personalized behaviour change interventions. Goal content refers to the reasons behind the decisions (i.e., the "whats") and are hypothesized by Self-Determination Theory as intrinsic or extrinsic goals [1]. Goal content's quality is a significant predict...
Article
Rationale: Whether self-regulation of food intake in weight loss maintenance (WLM) differs between being a short-term maintainer (having maintained without regaining less than 12 months) and a long-term maintainer (having maintained without regaining at least 12 months) is under-researched. Objective: The aim of this study was to explore the sel...
Article
Background: Low energy density foods (LED) reduce energy intake (EI); whether this effect is sustained over time and during weight loss is unknown.
