Effectiveness of a 12-Day Residential Wellness Program: A Pilot Study

Abstract

Intensive Therapeutic Lifestyle Change Programs have shown promise in improving cardiometabolic risk factors over short durations. This pilot study evaluated the effectiveness of a 12-day residential wellness program in rapidly improving selected cardiovascular disease risk factors. Eighteen participants attended a 12-day residential wellness camp emphasizing plant-based nutrition, structured physical activity, and lifestyle education. Baseline and post-intervention measurements included anthropometrics, blood pressure, lipid profiles, fasting glucose, and fitness assessments. HbA1c was measured at baseline. Paired t-tests evaluated changes in biomarkers, and Hedges’ g effect sizes were calculated. Sixteen participants completed the program. Significant reductions (P < 0.05) occurred in systolic and diastolic blood pressure, body mass index, and total cholesterol, with medium to large effect sizes. Triglycerides and LDL-C demonstrated nonsignificant reductions. One-mile walk time improved significantly. Three participants reduced/discontinued diabetes medications, and four adjusted hypertension medications. Participation in a 12-day residential wellness program resulted in meaningful improvements in selected cardiovascular risk factors and functional fitness outcomes. Medication reductions highlight the potential of short-term intensive lifestyle interventions to rapidly improve cardiometabolic health. Larger, controlled studies with follow-up to assess sustainability of outcomes are warranted to confirm these findings.
