i'm in the same boat too, been worried about gaining weight so much i've been racking my brains thinking of how i was going to limit my weight gain abroad! initially i was going to stick to just protein based foods but now i;ve decided to take 2 shakes per day (buying travel kettle tomorrow!) and have whatever i want for a main meal in the night, mainly something with more protein than carbs, that way i'm not depriving myself but i'm sticking to the diet halfway at least!
