I think here the claim is that they were both hams to begin with (though maybe the husband was not as fat as the wife) and husband become fit after lurking on voat -though the definition of "fit" for a former ham may not be what we consider fit-. Leavingfatwife guy claims his wife became a whale over several years after quitting running due to an accident. Nobody in these stories would want to be IDed anyway, so true or false is hard to tell, at least, IMO these are realistic tales.
