Optimizing Telehealth-delivery of a Weight Loss Intervention in Older Adults

Prescriptive A diet and exercise prescription individually tailored to each participant's multiple chronic health conditions will provide concrete advice with less autonomy, and will minimize risks of physiologic changes due to weight loss (hypoglycemia, hypotension, muscle loss). Licensed, trained professionals, Registered Dietician Nutritionists (RDNs) and Physical Therapists (PTs), will introduce clinical reasoning, knowledge, and experience, assess biological adaptations to weight loss, modify prescriptions based on changing medical needs, and provide real-time and asynchronous guidance. Registered Dietician Nutritionists (RDNs) and Physical Therapists (PTs)will deliver group and individual, live sessions to the home by telemedicine. Sessions will last 60-min (Registered Dietician Nutritionist: 20 min; Physical Therapist: 40 min).

Behavioral Health coaches have a bachelor's degree and take a 6-8-week certification program. Behavioral Health coaches will use a structured manual involving evidence-based behavior change techniques (problem-solving, self-regulation, motivation). Group and individual sessions will be via telemedicine.
