While that is certainly true, I, personally, would never do that because it would put me in a situation that the combination of biology (real hunger) and emotion (haven't eaten in a day!) would put me in an extremely dangerous place. Instead, I go for routine: regular, small meals; don't ever get really hungry; etc. Couple that with eating high quality food that you actually want to eat, and it has served me well. You are in a different boat. You physically can abstain forever, but your career doesn't allow you to. I could see how abstaining would be a very helpful option there.
