I have a question on etiquette realted to a friend's health

[HEyHEY]

My buddy, Jon, is a big guy. He weighs about 325. He hasn't always been large, when he was in his 20s he was much smaller. He's now 38-years-old.

Since moving here, he has gotten heavier. But the thing is it's the way he's eating. Whenever I go to his apartment there's pizza boxes and McDonald's bags and all that stuff (Worse yet cause McDonald's delivers in China). Now, I think some of it may be he's not used to the food yet and so he's buying western food for comfort but I don't know.

Anyway, I'm very worried about his health, and to see him eating like this makes me even more worried. But is it over the line to approach him seriously and say, "Look, you have got to stop eating like this, you're going to have a heart attack or something."

I don't want to hurt his feelings, and I'm sure HE knows he needs to stop too, but he just doesn't. Yesterday he had two big mac meals for lunch.
