@ms7dc If you are having trouble with diet you need to reevaluate your relationship with food. Trying fasting for one day, it might help you realize how much you are overeating every day.
@ryspi76 Can’t speak to making your wife buy into the plan, but your weight is primarily determined by diet. Add 30 min of cardio every morning, waking up at 6am, and you will be well on your way. You have time.
