For the past two days

Yesterday, I have business over 400 calories due to my shopping trip.  The average shopping trip for me lasts over two hours.  It was all worth it.  However, I realize that consuming 4000 calories is something that I can't exercise it out during the course of a day.  Today however, I have not done much movement.  I walk here and there but it isn't of much effect.  I will need to exercise all of those exercise calories off.  I have lost too much weight to go back and give up on myself.
