I am not on the road quite as much as some of the folks that the author works with (I don't, for example, need to know where to find healthy snacks in the Shanghai airport). But there are some helpful tips for those of us who do a lot of conference-style meetings, even if they aren't in glamorous places.
Overall, though, I've never been the kind of person who can keep a mental list of the 'good' carbs, and 'bad' carbs, and her diet is very focused on those kinds of things.
