I don't consider it IF, but I usually only eat two meals per day. Most times lunch (which is breakfast foods or left overs) and dinner. Because I am a night owl, lunch is around 2 and dinner around 8 or 9. Occasionally I will eat all three meals and most of the time on the days I only eat twice I will have a small snack in between.

I have never been much of a breakfast person, though - even when I have made a concerted effort to eat 3 squares a day because it's supposed to be better for me.
