Theme and goals of each module of the motivation and self-regulation arm.

Module (theme)	Core goals	Mechanisms of action
Module 1: My weight history	Review weight change history: weight trajectory and characteristics of previous weight changes (strategies and feelings associated) Identify weight loss strategies or approaches used in the last weight loss attempt and assess their sustainability in time	Self-awareness and competence
Module 2: My weight goal	Learn about self-monitoring and self-referenced feedback and its role in goal-setting and revision, and reflect on individual options and preferences Reflect on ideal and acceptable weights (and where these terms originated and what they mean to the person) Understand the importance of setting self-relevant and optimal goals: set weight-related goal	Self-regulation capacity, competence, autonomy (ownership), and intrinsic (vs extrinsic) goals
Module 3: Myths and facts	Promote factual knowledge about energy balance–related behaviors (exercise and diet) and WLMa	Competence and autonomous motivation
Module 4: My healthy goals	Promote awareness of multiple choices around behavior changes and WLM in the long term (there is no “right” way) Find individual interests and seek enjoyment and personal meaning around health behaviors Explore personal resources for engaging in health behaviors (eg, skills)	Autonomy (perceived choice), autonomous motivation, competence, and self-regulation capacity
Module 5: My goals and values	Prompt reflection on personal reasons for WLM (weight goals) and related behaviors by differentiating internal (autonomous) and external (controlled) motives and their relationship to sustained behavior change (sense of ownership) Explore sources of body image or ideal (eg, societal norms, media, and significant others) and its consequences (motivation and well-being)	Intrinsic (vs extrinsic) goals (ie, life aspirations), autonomous versus controlled motivation, autonomy (ownership), and perceived social influences and pressures related to weight
Module 6: Free and flexible	Identify functional and dysfunctional investment in body appearance (by exploring sources of body image or ideal (eg, societal norms, media, and significant others) and its consequences (motivation and well-being) and promote satisfaction with one’s body, at any size Explore links between internal (feels free and choiceful) and external (feels pressured) motives and eating and exercise regulation (eg, rigid vs flexible approach)	Intrinsic (vs extrinsic) goals, autonomous versus controlled motivation, autonomy (ownership), and rigid versus flexible behavior regulation
Module 7: What gets in the way	Identify challenges and barriers to current behavioral patterns and identify resources to increase capability to deal with them Identify strategies to deal with these barriers (coping plans) and to focus attention on how behavior changes serve other important life goals	Competence, autonomous motivation, and self-regulation capacity
Module 8: My support system	Identify sources of social support and reflect on what they mean (eg, pressured and conditional support vs unconditional support) Increase skills in seeking social support and dealing with social and peer pressures (eg, assertiveness) Explore reaching out to others as a role model or source of support and expertise in WLM	Relatedness, autonomous motivation, perceived social influences and pressures related to weight, and self-regulation processes
