Wanted to share my setup for the mod "Corruption" by Code Serpant. Skyrim AE x640
At the core, it's a Addition/Withdrawal mod focusing on fetishes. One of them being Feederism. Basically when the player eats more food, they increase their Addiction level. Once it's over the corruption threshold, you start building Corruption points. Corruption modifies the physical characteristics of your avatar - in the case of feederism its weight gain.
Once Addiction is over 0 (the scale is -100 to 100) it is considered permanent and will not decay below 0 until you've prayed (given gems) over to a shrine to Mara (but why do that?!?).
The other scale is Withdrawal. It is inverse to Addition. Meaning when you eat food your addiction goes up and your withdrawal goes down. When you don't eat food, your withdrawal increases while your addiction decreases. I do "cheat" a little by setting both to 100 in the debug menu. What ends up happening is that your character will spontaneously eat food in their backpack - increasing corruption/weight. Additionally, there is a random chance when you buy, loot, acquire food you'll eat it immediately. When your corruption is high enough - with a high withdrawal too - you will also spontaneously steal food and eat it. Comes with all the negatives of stealing in plain site too.
In my playthrough I also have WeightMorphs SE installed. Not in my screenshots is that I did increase "PregnantBelly" to 0.20, but overall I use it for added padding with values mostly lower. I use this for the Stamina/Speed debuffs as at higher weights your character will have lower stamina and move slower. Unfortunately WeightMorphs SE is a bit clunkier to manage (Corruption bundles its own meshes which are excellent).
Playing with the ReSave tool it lets you set any number for WeightMorphs SE's max weight. For me, the built in 2 seems to be the sweet spot. Like with most mesh based mods, both seem to fall apart at insane numbers. WeightMorphs above a two (for my settings) will start getting jagged lines around the waist. Corruption is saved in Skyrim's global settings and can be manually adjusted above the max via `set corruptionstatusfoodcorruption to 200` (replacing 200 with what ever you want). To me, it looks more realistic until you get over 300 - which your character starts hitting the skeleton limit (starts looking like a barbie in a beachball) making third person hard to play.
There's also the excellent BBW mesh I found online (and linked in the google drive readme). It provides the same sliders as CBBE 3BA but also adds a "BBW" preset at the top. I've added my "Chunk" slider preset to the Google Drive link as well. "Jere Bask" (character name) is set to "Weight 6" in RaceMenu if you want an idea of the starting point. If you're not familiar with CBBE and CBBE 3BA, you'll need BodySlide and run the build all on all the clothes in your game with your sliders set. I don't have the links handy, but I'm also using KS Hairdos (the number is somewhere in the mid700s) and "Simply Clothes" the shorts and top. She's a Breton.
TODO: I saw Dynamic Animation Replacer was updated today. I'd LIKE to get an eating animation mod installed. I plan to edit the Google Drive if I find one that works. Also in my game the belly physics are broken. Don't know if it's the BBW mesh or something else. I need to investigate that. But there's enough butt animation to keep you entertained for days it seems, lol. I'm also still playing with WeightMorphs. In an ideal world Corruption would just have a corruption cap editor. Maybe I'll look at the source and see if its something that can be added. I don't recommend the mod "Inncreased Food" - what happens is you'll basically go from 0-60 in 10 seconds flat. It could probably be improved with smaller multipliers.
There you have it. It's something I just got into (haven't played Skyrim since launch on a XBOX 360 so modding is all brand new). These are just a few things I came across in my 2 weeks of play. If there's anything I left out or anyone needs help setting this up, let me know. I could probably make a video detailing it.
