Like you, I also travel. However, I actually get leaner when doing so. The reason is I am so locked into staying lean when traveling that the temptation to wander off in my own kitchen doesn't exist because I am out of town. I suggest bringing food with you wherever you go. On the day of travel, I bring one meal for every three hours of travel, plus a backup meal just in case there are delays, flight cancellations, etc. I also pack snacks like nuts, fruits and veggies. Prior to booking my hotel, I request a small fridge in my room. Upon landing, the first stop is the nearest supermarket, and I get enough healthy food items for the length of my stay. If there is food service at the hotel, I always special order when eating there (or anywhere else for that matter). Always pack workout clothes, and even if all I do is walk the perimeter of the hotel and do a few floor exercises, it is better than inactivity. Most hotels have a gym, and many have relationships with health clubs in the area for day passes. I also reload on my food for my return date. It boils down to a little preparation that goes a long way. Happy travels!
