The purpose of this research study is to determine the effectiveness of nutrition tools to support weight loss among obese individuals. All participation will be based online and there will be no in-person visits. Participants will be given nutrition support tools for 6 months. Participants will be asked to report their weight and diet at the start of the study, and every month for 6 months during the study period. Participants will additionally be asked to report weight and diet at 12 months, 18 months, and 24 months after the start of the study. Total study duration will be 2 years.
Obesity is a major public health burden. Weight loss among obese participants may improve future health outcomes and financial burden to the healthcare system and employers. The effect of personalized meal planning and online food purchasing and delivery on weight loss and management is unknown. Design: This trial is an online, three-arm randomized trial to compare a meal planning and telenutrition tool, a meal planning tool only, and MyPlate optimization. Participants will be assigned to randomly assigned in a 1:1:1 ratio to one of the three groups. Participants will follow the intervention for 6 months after randomization and will be followed for an additional 1.5 years after randomization. Participants will report dietary behavior and weight at baseline and each month of the intervention (6 months), 12 months, 18 months, and 24 months. Population Approximately 300 participants will be enrolled and randomized (100 per arm). Participants will be adults living in New York state who are obese (at least a BMI of 30 kg/m2). Outcomes Primary outcome: weight change after 6 months Other outcomes: waist circumference; blood pressure, dietary changes, cooking, meal planning, and eating out frequencies
