The evolution of a 0.7-solar mass red giant is followed along the red giant branch, with mass loss included according to Reimers's formula. The red giant star completes its evolution by totally exhausting its envelope, without igniting the helium in the core. At this point, the core mass, which turns into a white dwarf, is 0.43 solar mass. The consequences of such an evolutionary path are discussed, together with the constraints that these results impose on the mass-loss rate during this evolutionary phase.
