Brief 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:

• 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.

Outcome Measures

Primary Outcomes (2)

• Weight Loss Goals

  Self-reported dream, happy, acceptable, and disappointing weight loss goals, reported as body weight and calculated percent reduction from current body weight.

  assessed once during the online survey

• Weight Loss Satisfaction

  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.

  assessed once during the online survey

Secondary Outcomes (2)

• Confidence in Achieving Weight Loss

  assessed once during the online survey

• Commitment to Weight Loss

  assessed once during the online survey

Study Arms (1)

Weight Loss-Seeking Adults

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.

Behavioral: Personalized 3D Body Visualization

Interventions

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.

Weight Loss-Seeking Adults

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

The study population consists of weight loss-seeking adults aged 18 years and older with a body mass index (BMI) of 24.5 kg/m² or greater. Participants are recruited from the general population through online advertisements and represent a broad range of demographic backgrounds. Individuals must be willing to complete an online survey and provide self-reported demographic and anthropometric information necessary for generating personalized 3D body visualizations. Individuals with a history of body shape-altering procedures are excluded.

You may qualify if:

• Adults over 18 years of age
• BMI ≥ 24.5 kg/m2
• currently seeking weight loss
• Willingness to provide informed consent
• Willingness to answer all questions related to enrollment criteria and provide the necessary information to render a personalized avatar, including sex, age, race/ethnicity, weight, and height.

You may not qualify if:

• History of body shape-altering procedures (i.e., breast augmentation, bariatric surgery, amputation)
