According to my meal plan kit during regular eating mode the items you can have in unlimited amounts are:
I can't believe it's not butter spray
bouillon, broth, consomme, fat free
lemon or lime juice
Coffee, tea, diet soda, regular or decaf
During Take Off 2
Fresh green veggies, diet beverages, I can't believe it's not butter spray and vinegar are the only unlimited choices.
In for the long haul!
