Phase I is totally doable when traveling. There's another thread somewhere around here where someone asked pretty much the same question. Wendys has a 2 for $4.99 deal right now where your hubby could get a salad and a bowl of chili for lunch. Mexican restaurants...get the fajitas w/o rice or tortillas and just have them give you extra lettuce and pico de gallo in it's place. There's lots of seafood options and, if you really want to get into it, you can buy the Soutbeach Dining Out Guide and it lists severals chains and what is acceptable to eat there for each phase.
