Like a lot of these studies they are only measuring one factor - fat gained/retained. So as usual its good to remind oneself to take it with a grain of salt and always keep a sharp eye on what works best for you overall. It beats waiting for some new study next year saying that people over 40 who exercise heavily without eating anything are twice as likely to have a heart attack or whatever. I know that if I go for a run first thing in the morning when its quite cold in winter without having anything to eat at all I can feel pretty bad for the rest of the day in comparison with (on a weekend) eating some breakfast and waiting for about an hour before I go out. In my case I usually pay attention more to how I feel rather than the results of some study.
