“I’m having trouble with my son, who is overweight. When he was younger, he was always very healthy and in shape, but he got married a few years ago and since then has been packing on the pounds. When I ask him about it, he tells me that it’s his business. I know he’s an adult and should be able to make his own choices, but I don’t think it would be loving of me to just stand by while he destroys himself. How can I help him change?”
