It may be that you're getting a little bit much protein and not enough fat to go along with it. Maybe just have two eggs for breakfast with a little cheese and some mushrooms or peppers.
I'd cut out the chicken salad at lunch and just have the burgers with a small salad. It looks like you're not spreading your carbs out enough, so have some vegetables with lunch and cut back on the amount of salad at dinner.

Also, maybe try ditching bacon and coffee for a week and see if that does anything. The bacon is very salty and may contain nitrates or other substances (possibly even sugar) that would affect your loss.

Also, check your soy sauce, I have two of them that are totally different carb-wise. One had 2 carbs, so it probably has sugar, but the Kikkoman's has 0.

Good luck to you!!
