Effectiveness of VR-Based Training Program in Weight Loss in Individuals with Obesity

The global obesity epidemic presents a major public health challenge, prompting the exploration of innovative interventions such as virtual reality (VR)-based training for weight management. This literature review synthesizes evidence on the effectiveness of VR-based exercise in promoting weight loss among individuals with obesity. A systematic search of PubMed, MEDLINE, and EMBASE identified 11 relevant studies, including randomized controlled trials, quasi-experimental designs, and pilot studies. Key themes examined include the physiological and psychological mechanisms of VR-based exercise, weight loss outcomes (e.g., reductions in body mass index and body fat percentage), and the advantages of VR interventions over traditional exercise programs. Findings indicate that VR enhances user engagement, exercise adherence, and satisfaction due to real-time feedback and gamification. However, limitations such as small sample sizes, short intervention durations, variations in VR systems, and accessibility challenges highlight the need for further research. While VR-based training shows promise as a complementary obesity management tool, larger, long-term studies are needed to standardize intervention protocols and assess scalability. Future research should also integrate VR with nutritional counseling and behavioral therapy to support sustained weight management and broader public health impact.
