Using Personalized Avatars as an Adjunct to an Adult Weight Loss Management Program: Randomized Controlled...

Area of Science:

• Behavioral Science
• Digital Health
• Obesity Research

Background:

• Obesity is a global health issue with poor adherence to traditional interventions.
• Lack of motivation and self-efficacy are key barriers to sustained weight loss.
• Avatar-based interventions can improve patient engagement and outcomes in chronic conditions.

Purpose of the Study:

• To evaluate if a personalized avatar enhances motivation, engagement, and health outcomes in a weight loss program.
• To assess the feasibility and acceptability of avatar-based technology for weight management.

Main Methods:

• Feasibility randomized design comparing avatar intervention with routine care in a 12-week program.
• Primary outcome: weight loss. Secondary outcomes: quality-of-life and self-efficacy.
• Qualitative interviews assessed feasibility and acceptability; quantitative data analyzed using descriptive statistics.

Main Results:

• Avatar group showed accelerated weight loss in later stages and greater improvements in quality-of-life and self-efficacy.
• Mean weight loss was 5.3 kg in the avatar arm versus 4.5 kg in the routine care arm.
• Participants found the avatar acceptable, reporting increased motivation to change behavior.

Conclusions:

• Avatar-based technology is a feasible and acceptable adjunct to weight loss programs.
• Personalized avatars can enhance participant motivation, engagement, and self-confidence.
• This approach shows potential for improving weight loss outcomes and promoting sustained behavioral change.
