Several studies have confirmed this phenomenon. It seems that triangles give you more sandwich filling per bite. A triangular sandwich has two 45° corners that allow you to bite much further towards the middle on your first two bites, where there is more filling. This is followed up by a perfect, crustless third bite as you take the space left in the middle. Bite number four is, of course, mostly crust, but you can’t have everything!
