Husband needs to diet, but won't

Food addiction is like other addictions -- nothing will change until the compulsive eater chooses change.

You should convey to your husband, "I am very worried about you. I hope you'll take your doctor's advice to try to lose weight, but I know I can't control you." Continue to set the stage for a healthy lifestyle, but don't police or comment on his eating.

I like the common-sense method used by Weight Watchers, which focuses on choices, portions, personal responsibility and group support. Their online program might appeal to your husband because it's private and self-policing. You could send him a link. You might receive some insight from the literature of Al-Anon or Overeaters Anonymous, oa.org.
