  The Cepheid mass discrepancy, the difference between mass estimates from
stellar pulsation and stellar evolution models, is a long standing challenge
for the understanding of stellar astrophysics. We discuss the current state of
the mass discrepancy and test the role of pulsation-driven mass loss in
state-of-the-art stellar evolution calculations of Large Magellanic Cepheids in
resolving it. We find that Cepheid mass loss is a significant contributor to
the mass discrepancy, but it is not clear if the metallicity dependence of
Cepheid mass loss is consistent with the measured metallicity dependence of the
mass discrepancy.
