I found a bug, if you happen to level up multiple times simultaneously you only get to choose a perk for one level up.
I was able to do this with one of the new "addiction" badges, specifically the "Foster's Badge" by getting addicted to cookies I was able to feed one of my tenants a gingerbread house, at level 1, and instantly blasted to some insane level, weight and size. I feel an "addiction" shouldn't allow you to feed your tenants more than their capacity, at least not by a lot.
Also, as someone else mentioned getting +2 badge points instead of capacity, digestion or happiness feels useless beyond level 1. Once you can put on the badge that grants BP for eating craved foods you can gather up a large quantity of BP in a short amount of time.
