Do my vault dwellers eat more when I watch them?

I recently started playing Fallout Shelter, but I go hours without opening the game and collecting resources. When I go back to the game it looks like a little bit of my existing resources have been used, but not by much. However, if I leave the game open, and watch my vault dwellers I can see my resources being used up at a much faster rate. I'm curious if this is explained anywhere. I'm also curious what the rate of resource consumption is while the game is idle vs the rate of consumption while I'm actively playing it.
