"after sleep deprivation, the cells became 30 percent less receptive to insulin signals"

Let's see, insulin causes lypogenesis; signaling fat cells to store energy as fat.

Sleep deprivation causes fat cells to be less receptive to insulin...

So, pass me the doughnuts while I stay up for the next week.

I know this was tongue in cheek, but:

insulin insensitivity = adult onset diabetes

so be prepared to have some toes or feet amputated (or to maybe just go blind) if you stay up with those donuts.

Low insulin is also a signal.
