Have you checked all the amounts per item on Fitday?? They have some FREAKY defaults (like 1 cup of mayonaise instead of a tablespoon).

Can you see how many carbs is in each item? You can click on the item and it pulls up the nutrition label.

That really does seem high unless it is your dressing - was it your own bottled dressing? If so, how many carbs? What kind of dressing?
