Sumo wrestlers eat up to nine square meals a day...I'm thinking that eating more often would HAVE to mean eating small snacks throughout the day, as opposed to actual meals.
You're actually very close. These are SMALL meals; more along the lines of what you and I would normally consider a "snack". To me........just me, now...........a protein shake is very filling and I easily count it as one of my "meals". I have one right before and right after each visit to the weight room at the YMCA (5 days a week; not necessary to do that much, though).
Think.........a tuna salad. Tuna on a bed of greens. Lots of folks grill up chicken breasts on the weekend, refrigerate them, and cut them up onto salads for meals during the week. You get the idea. SMALL 'meals'.
Think of the meals you currently eat and cut it by about half. You could actually eat a little more than that in each meal because eating more meals eventually increases your motabolism.
