From a bad radiator cap or from any systems leak whereby after you shut off the car, instead of drawing coolant back out of the reservoir, into the radiator, it just draws air back in, since the vacuum has been broken similar to a faucet vacuum breaker. The typical worse case scenario, that often can cause this, is a blown head gasket.

Put something under the car to make sure coolant is not leaking out from somewhere, like a pinhole in the radiator, or at the thermostat gasket or water pump, hoses/connections, etc. - as opposed to having it get burned in the combustion chamber(from say a blown head gasaket).
