Echoing Grot here in that you certainly not alone in your specific interests! There’s no harm in biding one’s time until you find the game or the developer which calls out to you. From my own experience, I can relate to lurking for quite some time before discovering a game or two that really grabbed me and in which I wanted to be part of the conversation on.
Another thing that really helps is the community-driven game jam (endearingly called the “Gain Jam”) where one can expect a vast influx of new ideas and concepts to be brought to the table, some of which may well appeal to you. The Gain Jam will be held from mid-September so stick around for that!
Conversely, whilst a lot of the games here do focus on “getting bigger” as a core theme, not all of them rely on food. Might I suggest the rather excellent Smasher and the Will o’ the Thiccs for you? Certainly features big-bellied, cuddly characters so could well be up your street!
