I just got burned on a road trip over the Labor Day weekend. I found myself in a seafood restaurant where the only thing I could afford in both price and carbs (or so I thought) was a stuffed seafood platter:

1/2 lobster stuffed
4 stuffed shrimp
1 stuffed clam
broccoli
small salad

I intially figured this meal at around 12-15 carb grams (OK for me, I am on OWL) but I didn't really know what was in the stuffing - I assumed mostly crabmeat. It must have been really bread heavy or there was sugar somewhere because two days later I had gained ONE POUND. The rest of the day was 12 grams. No other meal I had could have caused this. It was a delicious, wonderful, meal of course - but I paid the price. Please be careful in restaurants, there is really no margin for error. My total for the day must have been well over 30.
