Once you have undergone baseline physical assessments and questionnaires, you will be referred to a nutritionist and a physical rehabilitation specialist for individual consultations. You will receive a personalized diet and exercise plan and complete weekly exercise journals to track your participation over the next three months. After 4 weeks of this plan, you will meet with the dietician and rehabilitation physicians to check your progress and answer a questionnaire. There is an optional visit approximately 4 to 8 weeks later to check your progress and answer questionnaires, and then a final follow-up visit approximately 3 months after your baseline visit where you will again answer questionnaires and perform physical tests and questionnaires to check physical health. There are also optional blood draws at your baseline assessment and 3 months follow up visit, you will be asked to sign a separate consent form if you choose to participate in this part of the study.
