A healthy diet coupled with a daily routine of exercise is a good prescription for everyone interested in good health. But remember, every patient is different. Before making any drastic change in your diet, it is wise to communicate that intention to your doctor and discuss the pros and cons. The same advice is true for embarking on a new exercise program.

Such changes could have an impact on the test results your doctor relies on to evaluate the success of your treatment plan.
