Phenotype-Tailored Lifestyle Intervention for Obesity: A Randomized Trial

Subjects will receive recommendations for calorie and macronutrient intake, physical activity, and behavioral skills to be followed for 12 months and will be delivered by a multidisciplinary team of obesity experts in a 12-month structured follow up. Participants will meet with a registered dietician as well as member of the study team to learn more about their intervention. Diets will be prescribed for each participant with a 30% calorie deficit calculated from measured REE. Macronutrient composition will be guided based on the patient preference. Participants will be prescribed 150 minutes of physical activity per week (spread across 4-5 days) and recommendations to reach 10,000 steps daily. During the first 12 weeks, participants will be scheduled a 12-week behavioral program focusing on self-monitoring and stimulus control using cognitive-behavioral approaches to promote adherence to diet and exercise prescriptions.
