I can say that it is one of those methods that is highly effective in the short run, particularly the longer the distance. However, in the long run your body inevitably breaks down, either through injury or chronic fatigue. You simply cannot keep cranking out 100+ mile weeks with a daily caloric deficit indefinitely. That said, the "short term" can carry you for a good while, so it is perhaps not surprising that someone operating on a collegiate calendar might advocate some degree of calorie restriction.
In RWTB he has one of the guys (running ~80-100 mpw) on a 2,000 calorie diet. Can that really be healthy at all? I realize that at 6'2" 169 lbs., that I'm a big guy by running standards, but I don't think that I could go that low, and still run well.
