The only thing that really jumps out at me is that if you are perpetually tired, you will eat fatty or sugary foods in an attempt to keep your energy levels up. Whereas if you are well rested, that pressure to eat will not be there.

Any other reasons?

Read Lights Out: Sleep, Sugar, and Survival. It's quite an eye opener.

In a nutshell, sleep controls melatonin, which according to the authors controls everything else in your body: carb cravings, the resultant insulin, which affects seratonin, which affects dopamine, which can cause depression, cancer, etc, etc. Basically, the idea is to keep us on the same type of sleep schedule as our hunter-gatherer ancestors who would've gone to sleep when it got dark and gotten up with the sun, due to lack of electricity.

Simply, read the book. It's an excellent read.
