I generally don't critique other people's Fitdays because I'm such a newb at it myself. I'm just learning, so am not in a position to comment on others.
That being said, have you looked at your sodium intake at all (you can see it on Fitday)? That *could* be a culprit, if you're eating Lean Cuisines and processed deli meats. They have lots of sodium which can cause water retention (which, in turn, can register as a weight gain).
From what I've read, daily sodium intake shouldn't exceed 2,400.
As a side note, I'm very proud of you for logging everything! I do that, too, be it "good" stuff or "not-so-good". I even logged the one (yes, I said one) french fry I snagged from a friend the other day. I posted it as a JAB. JAB (Just A Bite) is my new custom food -- every JAB costs me 25 calories and 10 sodium. With a 25 calorie french fry, it was easy to stop at just one!
