-Summary

The goal of this observational survey pilot study is to learn how 3D visualization tools (i.e., personalized avatars) influence weight loss goals, satisfaction, confidence, and commitment compared to numerical weight outcomes in weight loss-seeking adults.

The main questions it aims to answer are:

1. What are contemporary weight loss goals (defined as dream, happy, acceptable, and disappointing weight loss outcomes), and how do they compare to goals reported in prior studies?
2. Does presenting weight loss outcomes using personalized 3D avatars result in different levels of satisfaction compared to presenting equivalent outcomes numerically as body weight?
3. Do predictive 3D avatars affect participants' confidence and commitment to achieving weight loss differentially than numerical weight loss goals?

Researchers will compare visual (3D avatar-based) weight loss outcomes to numerical (pounds lost) weight loss outcomes to see if visual presentation lowers satisfaction with potential weight loss and alters confidence and commitment.

Participants will:

* Complete a one-time online survey
* Provide demographic and self-reported anthropometric information to generate personalized 3D avatars
* Report weight loss goals and rate satisfaction with potential weight loss outcomes shown numerically and as 3D avatars.
* Complete questionnaires assessing psychological and behavioral weight-related factors.

+Arms and interventions

Arm	Type	Interventions	Description
Weight Loss-Seeking Adults		Behavioral: Personalized 3D Body Visualization	Participants are presented with personalized, predictive 3D digital avatars representing their current body shape and projected changes in body shape across increasing levels of weight loss. Avatars are generated using participants' self-reported demographic and anthropometric information. Weight loss outcomes presented visually via avatars are compared within participants to equivalent outcomes presented numerically as body weight (in pounds) to evaluate differences in weight loss satisfaction, confidence, and commitment.

Personalized 3D Body Visualization (Behavioral): Participants are exposed to a structured visualization task in which projected weight loss outcomes are presented in two formats. Outcomes are displayed visually using personalized 3D body avatars depicting changes in body shape across increasing levels of weight loss, and numerically as corresponding body weights. Responses to each presentation format are collected to evaluate differences in weight loss-related satisfaction, confidence, and commitment.

+Outcome measures

Primary outcomes

Weight Loss Goals [assessed once during the online survey]: Self-reported dream, happy, acceptable, and disappointing weight loss goals, reported as body weight and calculated percent reduction from current body weight.
Weight Loss Satisfaction [assessed once during the online survey]: Participant-reported satisfaction with hypothetical weight loss outcomes presented across increasing percentages of total body weight loss, shown both visually using personalized 3D avatars and numerically as body weight. Satisfaction is rated on a 10-point scale.

Secondary outcomes

Confidence in Achieving Weight Loss [assessed once during the online survey]: Participant-reported confidence in their ability to achieve projected weight loss outcomes presented visually (3D avatars) and numerically (body weight), assessed across increasing levels of weight loss.
Commitment to Weight Loss [assessed once during the online survey]: Participant-reported commitment to pursuing weight loss at varying outcome levels, evaluated for both visual (avatar-based) and numerical presentations.
