I am sure this changes over time - especially with aging or injury - but to me, how one lives "normally" is not too different from how one lives on vacation. Visiting family or a trip to a foreign country still have me essentially being true to myself - ie not sitting on a couch and stuffing my face but also not seeking out the nearest gym so I can hit the treadmill for 2 hours. Luckily, on a trip, I tend to be walking all over the place - or better yet - riding all over the place, and the biggest difference of all to my eating is that I make room for dessert as often as I want. What I find, though, is that I don't actually always want dessert and come to some happy medium where I am not depriving myself as much as sated and being more picky. In general, I am a sucker for tiramisu but after maybe two of those in a week, I'm good until next time. I'll try something else and/or not want dessert at the next meal.
