Got another stupid question...

So, being a single guy, even though I cook there ain't much in my fridge and especially the freezer. It does the defrost thing and have put a thermometer in both the fridge and freezer. By randomly checking them fridge seems to cycle from about 34°F to 40°F the freezer -10°F to just below freezing.

The question is...

If I fill the empty space with containers of water, or ice in the case of the freezer, making the air space in them smaller will it run less and end up using less electricity? The air space is going to warm some when I open it for access, but does the air space cool down quickly enough having less air space doesn't really matter much at the end of the month?
