When I dieted a couple months back with no exercise I lost close to 40 pounds just eating a light breakfast and just a heavier lunch, and no dinner. Worked for me because instead of eating 6 smaller meals of stuff that are light and not liking what I was eating, I just had a really enjoyable lunch where I just ate what I usually wanted.

Starting out was hard, but I'm so used to it already and don't feel hungry with just one real meal.
