Is this trial a fit for you?
✓Likely a good fit
Adults with overweight or obesity (BMI ≥25, or ≥23 for Asian origin) who have internet access and can attend in-person DXA and lab assessments as required.
✕Probably not a fit
Individuals unable to participate in weekly sessions or unable to access online resources or required testing may not benefit.

What this trial studies
This interventional study provides a 12-week online plant-based nutrition education program delivered in a community setting. Participants attend weekly physician- and dietitian-led sessions to learn and implement a vegan-style diet and receive practical support. Assessments include body composition via DXA, HbA1c, lipid panel, and a cost analysis at baseline and after 12 weeks. The study will evaluate feasibility, implementation, and efficacy of the program in real-world conditions. Enrollment targets adults with BMI ≥25 (or ≥23 for Asian origin) who have internet access and can attend required measurements in DC and nearby facilities.
Why it matters
Potential benefit: If successful, participants may lose weight and see improvements in blood sugar and cholesterol through a feasible online program.
How similar studies have gone: Previous studies of plant-based and lifestyle interventions suggest potential benefits, but online, guided programs for weight loss in this specific setup are still being explored.
