I agree with LapLap that it is more of personal choices but I also agree that places with good "healthy" food are not always easily found (especially in airports - ok, that goes for good unhealthy food too). I normally have to hunt through the whole terminal before finding anything that is lower in fat.

I always make it a habit to eat healthier food when I travel, especially at airports since I have been contorting myself in Y for a few hours with not much of a movement and because I normally cant get my full workout in at the hotels.

My solution would be to eat sushi all the time since I dont eat the roll kind (which are drowned in sauces) - high in protein and low in fat.
