can't speak for anyone else, but it's definitely NOT psychological for me. I am extremely sensitive to blood sugar levels and can feel them plummeting... running on an empty stomach (whether early or late in the day) is a guaranteed way to bonk and end up doing a death march home.
Ditto, me too.
I guess it also depends how early you eat dinner, and how early your run is. If you ate dinner around, say, 6pm, and ran at 8am, that's a LONG time.
This reminds me of runners who train without fueling during long runs based on training their body to burn body fat and not the instant sugar from gels/bars/etc. They admit they feel like crap during the training though. I'm of the opinion that I'd rather feel energized and fresh during a run, and that means eating within a few hours of running, and fuelling as necessary during a long run. If that means I don't burn more fat than I otherwise could, that's fine with me....I'm in it to feel good about running and enjoying the exercise, not to torture myself!
Well, that may be, but that's not what the study was about. It's like if there was a study that said "pink has been shown to increase happiness in those who wear it" and you respond with "yes, but I like green". The study was looking at physiological effects of running on empty - not the enjoyment level or performance level of the runner's experience.
