Interesting. I was experimenting for a little bit with weekly fasting, skipping Sun bfast/dinner and Mon bfast/lunch (to make it non-intrusive to the family schedule). I knocked it off when I was training for a duathlon and started to feel a little weak, but now that's over, I should consider picking it up again.
