Actually, just on a loose estimate, that look like around 2600-3000 calories. 6 ounces of cheese is a LOT, so are 3 cups of milk. 4 slices of bread is quite a few calories from simple carbs, etc. I look at that diet, and I think I'd be hungry. I eat like a hog now, though, and feel pretty stuffed most of the time, and still probably clock in around the same number of calories a day.
I dunno, just an observation.
