Why is my son not ashamed of his weight?

I guess he likes food a lot and as of right now does not really care about his current heath stage. You have to get rid of the junk food and prevent him during the times he likes to just eat and eat. Sit down with him and show him the dangers eating too much unhealthy food. I know, say that being really fat is a turn off for girls hahahaa that should get him thinking about his weight!!
