I am not gonna suggest anything but double it, but, out here, I have noticed, especially on warm days, that construction workers eat fairly moderately and actually eat less than many office workers at lunch. I think it has to do with knowing they have to get back to work. Many of the Mexican and Southwest guys actually eat a lot of fruit at lunch.
