Is my husband unhealthy in his lifestyle?

My husband is 48 years old. Great guy but I am very worried – he eats mainly fried and convenience food, very little unrefined food. He smokes quite heavily, does no exercise at all, not even moderate walking, and drinks 2–8 alcoholic drinks at least four times a week. He is only slightly overweight. Also refuses to recognise that his diet and lifestyle will harm him. His excess weight is only on his stomach which I have heard is also unhealthy. He does not believe that he would feel better if he changed his habits, but he has always eaten/drunk like this and smoked, – feel sure that it is doing him harm.
