How do i get my husband to lose weight?

Some ideas: He wants to lose weight. Remember this and don't criticize. You're probably already a good cook; expand your repertoire to yummy things that aren't greasy, salty, or sugary. Start preferring these yourself -- pretty soon the stuff most of us overeat will disgust you. He's likely to imitate you. Explore aerobic fitness options for yourself & work hard at it; again he'll imitate you. Enjoy.
