Yeah, I wouldn't say it's a bug either. They do live their own lives and if you play certain aspects a lot (like restaurants that have the tendency to have the same people there all the time), they get fat.
Sorry, but I came here looking for a fix for this. This is not a feature, it's a bug--most likely an xbug where it's working as designed but not working as the end user expects. I'm also a rotational player and my wellness guru sim is best friends with another playable sim who has the fine dining quirk and any time they are together my healthy wellness--makes her living from teaching other sims to eat healthy and do yoga--sim becomes an obese white cake binging idiot. It's frustrating because I shouldn't have to worry about maintaining *my* gameplay and storyline because of this stupid gameplay breaking issue.
I think it's great the EA allows for all different players to play with all different body types. But because I like to take my playable vegetarian fitness fan celebrity sim (which is why she is best friends with my currently unplayed wellness guru sim) and her celebrity partner out to posh restaurants for their dates--since everyone else dining there is an npc, suddenly my town full of diversely shaped sims all turn into grossly obese sims after a full night of gameplay. This makes me want to go back to Sims 2 which lacks entirely the body diversity that Sims 4 has.
Diversity and *different* body shapes does not mean all fat sims.
Sorry to necro this, but is there a fix or at least a mod to resolve this issue? I just want my unplayed sims with high fitness levels and likes to be in the same state I left them at and I want the chubby NPCs to stay chubby and the skinny NPCs to stay skinny. And I'm not a fan of "potions" or unrealistic gameplay nor do I want to remove all of the restaurants or kill all the npcs in the neighbourhood and start over.
BTW: I hate it when players ask for help and then are told--it's fun to have a borked game. It's not.
There's not a whole lot you can do to keep a sim at the fit/fat state you want in the game when you're not playing them and go a long time between playing some sims. I fight that battle all the time. But you mentioned your sim while an NPC eating a lot of white cake. If you have Eco Lifestyle, then check the active NAPs in the zone you are playing in. I don't have my game open atm and I've forgotten the name of the NAP, but there is one, when active, causes the NPCs (and actives) to cook white cakes a lot, almost continually at times. And so there is a lot of cake around at residential lots in a zone with that NAP active. So, you might want to check and repeal the NAP if it is active. It might help some to keep your sims where you want them.
Hope this helps.
