In a Chinese randomized trial of adolescents with excess body weight, an eight-week supervised adaptive-VR sports program reduced fat mass by 4.28 kg versus control (95% CI 2.22 to 6.35 kg reduction), while supervised physical sports reduced it by 5.06 kg versus control (95% CI 2.98 to 7.13 kg reduction); the two active interventions did not differ significantly.
What this does not establish
This is not evidence that unsupervised consumer VR, ordinary gameplay or AI alone produces weight loss or durable population effects.
Counterevidence & uncertainty
Intensive coaching, school context, selected adolescents and concurrent nutrition support constrain transportability.
What would change the reading
Update with multisite pragmatic trials, longer follow-up, adherence outside supervision and cost-effectiveness.
