One of your friends has heard that you just completed a nutrition course and has come to you for help. His father has just had a heart attack and underwent coronary artery bypass surgery, so he wants help with planning a new way of eating that will help him lose weight and reduce his risk of having a heart attack. Using what you have learned in this course, detail what you would tell your friend. Will you put any of the changes that you are recommending to your friend into practice?
