Your doctor may refer you to other professionals in order to develop a comprehensive diet and exercise plan. A nutritionist or dietician can go through your dietary history in more detail and provide tips on ways to incorporate healthier eating into your daily life. The doctor can also refer you to a physical therapist or trainer who can help determine appropriate exercises, particularly if you have problems like back pain or troublesome joints.
Your doctor is there to advise you. If there is anything at any point in the visit that you do not understand, do not hesitate to ask. Every doctor wants to provide his patients with the best care possible. Following the above recommendations will allow your doctor to do so and will help you get the most out of your visit.
