I managed to only put on 2lbs when i went to america for three weeks last year, and half of our trip was in Texas, everythings bigger in Texas, but i swam in the pools if i had a chance, ur walking round so much and i was also a little dweeby and used the gym in a few places, not enough to say i wasnt enjoying myself, just if i had a spare half hour before getting ready to go out for tea or something. The other part of our trip was to Seattle and i found it much easier to eat slightly healthier there (not that i was depriving myself!) Just cuz alot of the food was fresh seafood and things whereas in Texas everything was fried. We also did a Man v Food challenge with a gigantic cinnamon roll so just go enjoy urself and try to make a little good decision here and there and ul be fine. Have a fab time!! X
