Be very careful with this approach, due to blood sugar levels. I can't go more than 90 minutes between small snacks without suffering shakes, and I'm not diabetic. Even a small orange or pear will bide me over. I know some airlines that ban flightcrew from intermittent fasting when on flying-days for that reason.
