Hey Philana

(Totally off topic, but how crazy is True Blood this season?!)
Changing habits can have an effect on our weight, but mathematically if you're eating below your maintenance level then you should be losing fat.
However, we all know that losing fat doesn't mean that it will show on the scale. (Water retention, food in our system, sore muscles etc. All those reasons, plus the unknown mysterious reasons!)
You say you're returning to exercising more this week, and that should play some role in your calorie deficit. Were I you, I'd continue staying within my daily calories (regardless of how the meals are spaced out), add in the activity for two weeks and see if anything happens.
If not, then I'd look into changing something else, but to start... just the activity.
