Temperature self-regulating food delivery systems are provided having a magnetic induction heater () and an associated food container () equipped with an essentially permanent ferromagnetic heating element (). The heater () and heating elements () are designed so as to heat the element () to a user-selected regulation temperature when the elements () are coupled with the heater's magnetic field, and to maintain the temperature in the vicinity of the regulation temperature indefinitely temperature regulation is a heating achieved by periodically determining at least two parameters of the heaters resonant circuits related to the amplitude of the resonant current passing therethrough during heating and responsively altering the field strength of the magnetic field. Preferably, the value of the resonant circuit amplitude and the rate of change of the amplitude are determine.
