Weight Loss and Physical Activity Lifestyle Interventions In Post Liver And Kidney Transplants

This project aims to understand feasibility, acceptability, and appropriateness of using connected health services (use of Fitbit and Scale), and nutritional coaching group sessions as a lifestyle intervention for post-transplant patients seeking weight loss. Secondarily, the investigators aim to assess effectiveness of the intervention to generate weight loss. Enrolled patients will receive a wrist activity tracker (Fitbit Charge 4) and a scale, of which information synchronizes to the electronic health record. Steps, usage, and weight values will be recorded and analyzed from the devices. All patients will be followed with monthly calls to assess issues with devices, and address case-specific questions. Simultaneously, half of the patients will be randomized to receive every other month nutritional coaching group sessions on topics related to nutrition and physical activity. Patients will have an in-person follow-up appointment where laboratory values, body measurements, and physical and mental readiness for weight loss surveys and scales will be applied at 6 and 12-months. Patients that don't accomplish weight loss goal at 6 months will be invited to cross over to the nutritional coaching group sessions intervention arm.
