Calories in VivoFit and MFP

Options
I want to be sure I understand this. (I just got my VivoFit 1 yesterday.) I'm showing calories at 1189 so far today. I'm assuming that I've burned 1189 calories so far just by breathing and doing whatever I'm doing. When I go to GarminConnect, it shows I've burned 439 calories (which are the calories I burned in a workout that I posted onto MFP.) Why wouldn't GConnect show ALL the calories I've burned? Why not show the full 1189 against my caloric intake?
