You don't have to want to eat; you just have to do it.
Plan when you are going to have a meal and keep track of the time. Make plans of what you are going to eat. If you can't finish the meal you plan, then have the rest later as a snack.

I often tend to forget lunch, but I always have a very good idea of what I intend to eat during the day.

Isn't it lovely to be in control and not at the mercy of the carbs?
