I'm gonna chime in on this.
My biggest breeder male, a pastel at 1200 grams ate a small meal every other week all through the breeding season.
My two smallest breeding males ate an average of once a month maybe, sitting at 450 and 525 grams respectively.
My non breeding male at 650 grams, stopped eating completely.
I think it depends on the individual snake. I offered small meals to all my males, meaning most of the season they got adult mice instead of rats of any kind. Eating was pretty much hit and miss but I kept offering. I did find with the two smaller males offering food two days after I pulled them from the female encouraged eating to a degree.
