Not really much you can do. If he knows and is even indulging in this fetish he's probably taking it at his own pace.
Simply continue to support him and remind him how much you appreciate him. Maybe sometimes pick up a snack he likes occasionally to show him you like the results?
Being patient and understanding is the best course of action right now. Even then buying them snacks to urge them on might be kinda teetering between none consensual feeding. As long as both parties understand each others wants and desires and respect each others boundaries.
I suppose you could also just ask him straight up how he feels abount your desire for him to chub up and how it feels at the moment.
