It depends on where you change it. If you lower the transmission size at the transmitting host you simply are putting more, smaller packets on the wire. This creates slightly more overhead because more packets means more bandwidth being taken up by headers.
If you leave the MTU on the host at 1500, for example, but lower the MTU on your router then you'll cause fragmentation. This also uses extra bandwidth for all the extra headers but it also creates more work for the receiving host as it has to put all those fragments back together.
