Answer:
the appropriate tone to use in this instance would be a stern but kind and understanding tone. you don't want to be too forecul in order to avoid the patient rebelling however, you must be stern since it is a matter of life and death; the best course of action is to be entirely honest about the serious effects his habits have on his health. Based on his past actions of following the regimens prescribed by other doctors, he seems to want to lose weight and do better. The best way is to entirely avoid the point of temptation and try to keep it out of sight and out of mind. being kind is important since people react better to kindness rather than control, showing how much you care could cause the patient to want to do better.
