sleep is tied to the diurnal cycle

Is it? Domesticated dogs derive from a nocturnal species, when born feral they are nocturnal, but have no problems being diurnal when raised so by humans. Humans can easily adapt to two shorter sleeps or even the weird polyphasic routine.

OTOH "food coma" is a thing.

when born feral they are nocturnal

Not sure this is true. In the tropics (where there are a lot of feral dogs) the peaks of activity for most everyone is dawn and dusk, avoiding the midday heat. As far as I know nocturnal predators certainly exist but are rare.

Humans can easily adapt

Don't know about that either. Humans can adapt. Some humans can easily adapt. A lot can't.
