It seems the main-stream is finally catching up.
The following (short) excerpt from a Spark People article on eating 5-6 mini-meals per day:
Eat balanced meals for the best results. Your mini meals should be nutritionally balanced, containing complex carbohydrates, lean protein, and healthy fats. Each meal should be about half the size of a "normal" (3-meals-a-day-sized) meal. So when you eat these "mini meals," you take in the same calorie and nutrients by the end of the day, just with different timing.
