I am well aware of what you do, trust me.
However I still say any fit person should be able to go without a meal IF necessary, without becoming incapacitated as some have suggested.
As I said before, obviously on long haul flights you would NEED to take something with you or be supplied with food.
However I cannot see how it is a drama on short haul flights, even if you do 5 legs a day, that means you have 4 transits where you can get food if you are starting to feel light headed.
As I also said before, the America West Pilots here in 1989 used to manage all their work during turnrounds, buy and eat their Lunch in the terminal, and say what is the holdup.
