Might as well jump on the band wagon -
Here are my predictions
Ordered Biggest to Smallest / Most to Least
Reason -
Top 5 - Dina - All she does is eat and Gretel can’t get to big for the sequel unfortunately.
Butts - Heather - Sam might be gaining on her, but Heather is truly unmatched.
Belly - Dina - if she’s number 1 she kinda has to get this, but Steph and Gretel won’t be far behind behind I imagine.
Breasts - Sophia - clear winner, Freshas medicine can’t beat pure natural gains.
Sister’s - Stephs - She’ll go from fasting to fattest. (Inclusion in Slob teir explanation - I reckon she’ll go from a woman of cloth to in need of a cloth to wipe away her foodstains if her pre-fast feast was anything to go by. And I think it’d be funny for Jim to find his wife alot bigger and tad messier than before when he returns. I’m sure he’d drop a corny line, like “there’s just more of you to love now”.)
Twin’s - Heather - If Sebastian’s speech to Heather in the red route was anything to go off he’s got big things in store for Heather. And she’s already the big sister whats wrong with her getting a tad bigger.
Biggest berry - Dana - Automatic win, unless Lily gets experimental.
Slob - Dina - Two words : last update.
Savoirs - Alex - Bound to be something with one of the white haired elves and I think Sebastian and Cynthia are busy.
Feeders - Cynthia - Consider her history, there’s no debate about this.
Thin Gang - Not much going on here.
More relevant later - Plenty will be going on here. 
Lads - Mauve - It’s not Lily’s first rodeo so I guess we can expect big things, considering her introducing Biggo.
