Hotels continue to add low-calorie, low-fat options to their menus as more travelers strive to maintain a healthy lifestyle when away from home. Sofitel, for example, launched its De-Light menu last month in the U.S. The menu features three-course meals that are less than 500 calories and don't contain oil, butter, cream or flour. The hotel companies are "saying, 'Hey, we understand that being on the road is tough, but it shouldn't necessarily impact your healthy lifestyle you have at home. So this is one way to make it easier for you.' " said Jan Freitag of Smith Travel Research.
