Background: Lifestyle interventions (LIs) are the cornerstone for obesity management. The Mayo Clinic Diet (MCD) offers two approaches for LIs: the In-Person LI (IPLI) and the Digital Enhanced LI (DELI). The IPLI includes a 2-day in-person program with monthly follow-ups, whereas the DELI provides on-demand digital tools. The comparative efficacy of these approaches is currently unknown. Methods: and weight metrics at least 3 months after starting either the IPLI or DELI program. The primary endpoint was the total body weight loss percentage (TBWL%) at 6 months. Results: The study included 133 participants in the IPLI cohort (mean age 46.3 years, 65.4 % female, BMI 36.4) and 9603 in the DELI cohort (mean age 60.1 years, 85.0 % female, BMI 33.1). The DELI group achieved superior TBWL% at 1, 3, and 6 months compared to the IPLI group (3.4 % vs. 1.5 %, 4.7 % vs. 2.4 %, 5.3 % vs. 2.9 %, respectively; p 5 % TBWL at 6 months (OR 1.66; 95 % CI 1.08, 2.55, p < 0.023). Conclusion: The DELI approach resulted in superior weight loss outcomes compared to the IPLI. Further research is needed to explore how digital tools can improve weight loss effectiveness.
