If i’m not wrong the main macronutrients are fats carbs and protein, i don’t know if that’s for teens but those are the main macros
I'd say that the doctor would recommend to 1: to start a low-calorie, low-fat diet, 2: devote time to follow a workout plan, and possibly 5: Join a weight-loss support group, but I'm not sure about that one.
The reason the doctor wouldn't recommend 3 is because you're supposed to eat several servings of fruit per day, not once a week, and the reason the doctor wouldn't recommend 4 is because an increase in food consumption would add on to the patients problem of being overweight rather than help it.
My answer would be to make sure to include the F.I.T.T principle (Frequency, Intensity, Time, and Type). I am not completely sure if it is correct so correct me if I am incorrect.
