  We show that warm inflation can be successfully realized in the high
temperature regime through dissipative interactions between the inflaton and a
single fermionic degree of freedom, provided that the latter's mass is an
oscillatory function of the inflaton field value. We demonstrate, in
particular, that despite the consequent large amplitude oscillations of the eta
slow-roll parameter, their effect is, on average, sufficiently suppressed to
allow for a slow-roll trajectory. In addition, we demonstrate that, even though
this also induces a parametric resonance that amplifies inflaton perturbations,
this has a negligible effect on CMB scales in the relevant parametric range.
Hence, the "Warm Little Inflaton" scenario can be realized with one less
fermionic degree of freedom and no need of imposing an additional discrete
interchange symmetry.
