Odd number of slices in a loaf of bread

Brian Leekley: My bread theory: To have a classic loaf of bread shape, the middle slice needs to be the largest, with each slice in turn to the left and right of that being of about equal size, each subsequent slice on the left and the right being a little smaller. With matching slices on either side of the one biggest slice, there must be an odd number of slices. Of course one can cheat and get an even number of slices by not having all slices of uniform width. Mathematicians, is that right?
