An observational study in Overweight and Obesity, sponsored by Pennington Biomedical Research Center. Not yet recruiting. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-04-21.
Sponsored by Pennington Biomedical Research Center · Observational
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:
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:

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.
Exclusion Criteria:
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
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 Goals
Self-reported dream, happy, acceptable, and disappointing weight loss goals, reported as body weight and calculated percent reduction from current body weight.
Time frame: 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.
Time frame: assessed once during the online survey
Confidence in Achieving Weight Loss
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.
Time frame: assessed once during the online survey
Commitment to Weight Loss
Participant-reported commitment to pursuing weight loss at varying outcome levels, evaluated for both visual (avatar-based) and numerical presentations.
Time frame: assessed once during the online survey
