I think that for me the key was to start with baby steps. I didn't change my lifestyle drastically at first. I just changed one little thing, eating something that had few calories than what I had been eating before. I also made a commitment to myself to spend 5 minutes a day exercising. I hate(d) exercising, and could never quite find the time to do it. But five minutes? Ya, I could work that in.
These two baby steps because habit pretty quickly. I found I could and wanted to make more changes in the same direction. But it did take some time. I really think that if people want to make lasting changes in their lives, going slow and seeing what changes they can really live with in the long run is the way to go.
Good luck, and good luck to your father as well.
