The measured values of P-dot(orb)/P(orb) in the four low-mass X-ray binaries (LMXBs) in the Galaxy whose orbital period changes have been reliably determined disagree markedly with what would be expected for orbital evolution driven by angular momentum loss due to gravitational radiation. On the assumption that the observed period changes are secular and not due to some longer-term periodic change, it is argued here that the observed behavior of LMXBs can be explained as the result of mass loss from the companion star caused by irradiation of the secondary star and accretion disk by the primary. The typical lifetime of a radiation-driven LMXB is expected to be a million to ten million yrs. This reduced evolutionary timescale can resolve the statistical discrepancy between the number of binary millisecond pulsars and of their presumed LMXB progenitors if about half of all the LMXBs are radiation-driven.
