As Grumpy says... post some menus. Even when we know the diet back to front, things can slip in, or even, because we don't look at our entire day/week written day, we can have too much dairy or too many tolerated ingredients.
I'd advise dropping all tolerated ing'ts for a few days to see... and avoid prepacked meats etc, if you're having them... watch your salt consumption... check you're having enough H2O... increase exercise... and, if all that doesn't cause a loss, I'll eat my hat!
