Fat Sims? Learn How The Sims 4 Manages Weight, Muscle and Fitness


Over the years I’ve seen plenty of people
complain about how their Sims get fat over time. Because of this I thought it’d be fun to do
some playtesting and see if some guidelines you read about preventing fat gain are really
true, mainly the idea to only eat when hungry. At the same time we’ll discover several little
known things about how The Sims handles fitness and fatness. We know The Sims 4 uses a calorie system for
foods, meaning some foods contribute to weight more than others. Calories in this case are completely irrelevant
to how filling a certain food is. Many high calorie items like cake are not
very filling compared to even a garden salad which is one of the best foods, both in terms
of value and in reducing insurance claims from fire. However it’s not as filling as spaghetti. What people will notice is their Sims get
fat, despite the players only eating when their Sims are hungry. This is due to the game’s calorie system. Every pound is 3500 calories, just like in
real life. Foods also have their own numbers that determine
how filling they are. I tested whether eating only when hungry prevents
weight gain, and as you can see it does nothing of the sort. The problem is that calories on Sims don’t
really decay unless you do some activities that reduce them, so a lot of elder Sims can
end up chubby if they don’t focus on fitness especially on longer life spans. If they’re high calorie enough every few meals
the Sim puts on a pound or two. Ultimately the lesson here is Sims lack a
basic metabolism and must burn calories manually or else they’ll gain fat. Because of this, eating anything but low calorie
food will gradually add on pounds, though some foods are far far worse than others. Sims who get rich and live like they are will
be more likely to eat the expensive meals from the high level homestyle and gourmet
cooking list, and they’re almost all over 300 calories if not double that. Lobster Thermidor has the highest calories,
at 800. But it’s not as bad as a black and white cake,
which has 500 but only fills hunger by a small amount. At least you can lean on the thermidor to
top off hunger if it’s really low – a garden salad can’t do that. So, yeah. Certain foods are not as filling as others,
but when made of high quality get a boost to how filling they are, about 30% more. For losing weight you’ve got to counter the
high calorie foods and either hop on a treadmill, swim, or jog while eating lower calorie foods
to speed it up. These cardio activities directly lower body
fat while not making Sim muscles bulk up. Work on the bodybuilder aspiration while you
do so, and you can get the long-lived reward trait eventually, adding to your Sim’s life
span. Each minute on the treadmill reduces fat by
a small amount. You only need to do a few hours a week to
keep your Sim in good shape. This is something that a lot of people miss
and there’s no need for equipment – treadmills are only slightly better than jogging. So we’ve talked about fatness, let’s look
at the hidden fitness stat, or how muscular a Sim is. Building muscle on a Sim is a different animal
because muscle decays over time. When you make a Sim, it locks in the muscle
amount you selected. This is the floor for that Sim, and their
muscles aren’t supposed to decay below it. So if you start at a 5 and work your way to
full muscle, it’ll not go back below 5. Still, every day about 4% of your muscle will
be lost unless you lift weights. You’ve got to work to keep the muscular look
you want for your Sim and one long session each week is about all it takes. Players who take the bodybuilder aspiration
at the time of Sim creation get High Metabolism, which not only cuts fat gains in half while
helping with muscle gain, but also lets you click them to get an energy drink on the spot
that will help them get in the mood for exercise. At level 5 fitness Sims get the protein shake
recipe at the bar. This gives a 50% boost to fitness gains while
active. You can use it to keep your Sim’s muscles
intact without working out as often. Something I realized working on this is that
when Sims get to higher fitness levels, the hygiene decay they suffer begins to get smaller. I suppose they’re sweating less and this makes
perfect sense! Knowledge of the fatness and calories systems
are also useful if you have a Sim who is very active. If you do not want them to be skinny, you
need to eat high calorie foods in order to offset some of the exercise. Just keep in mind weight lifting alone won’t
cause your Sim to lose body fat. But, Sims who jog a lot can get far too thin
and should eat a few high calorie meals each week. There are a couple of hybrid activities, like
punching bags and the training dummy from StrangerVille that increase fitness while
reducing fat. Strangely, basketball increases fit but doesn’t
reduce fat. It’s like whoever made that thought the fit
stat is for keeping Sims slim. Speaking of bugs, I went on a quest to document
the calories and satisfaction a Sim gets from eating different foods and found some strange
things. I haven’t put this up on the guide yet, but
I will. To keep the list within reason I only did
those that are attainable from leveling cooking and gourmet cooking. Let’s be real, this game has a lot of foods
and 2 hours of this left me starving anyway. Just the names of foods was triggering me
to go eat some leftover hamburger helper and I haven’t even heard of some of these recipes! To create an Efficiency stat at the top right
I did a little math, dividing the amount of hunger stat you get for eating a food by its
calories in order to find the most efficient diet foods. Players may also be interested in knowing
which are high calorie. There are some obvious winners like garden
salad, which blows the fair competition away. Even mac and cheese is OK and not nearly as
bad as something like fish tacos, BLTs or Monte Cristo sandwiches. I’ve bolded the best recipes along with the
worst, ranked by the efficiency. Something I noticed while doing this is a
pretty annoying bug. A bunch of recipes from expansions are broken
under the hood. They have 0 calories and are mostly set at
the maximum fullness. So if someone out there said, “My Sim doesn’t
get fat I eat tilapia” they were correct in noticing it. This is definitely a ‘someone forgot’ thing
as you only have to make up 2 numbers to make these foods work. All the outdoor retreat foods have 0 calories,
and that pack is not the only exception. It’s as if devs at different times forgot
that the calorie mechanic existed and copied placeholder code for a basic recipe over to
them. I’m probably going to file a bug report for
it as I have a number of broken recipes to share. So, that’s a lot to take in about a very specific
topic but people are supporting me on Patreon and I wanted to make a new video this week. I’m grateful for you all signing up, and visiting
the guide. Things look a lot better than they did a year
ago and I have the entire Sims community to thank for that. I hope some of you found this stuff interesting. It was fun to research it. See you next time.

  1. Here's a link to the table, Sorry I'm late to post it: http://www.carls-sims-4-guide.com/tutorials/calories.php

  2. I've never had issues with my sims gaining weight. I play a four male teen household – two athletes (identical twin brothers) and two geeks (cousins with the common parent being identical twins). I generally wait for needs to go orange – more efficient, which means eating twice, sometimes once per day (also bulk-cook 8 person meals every time). I'm a skill-a-holic so it may take a bit, but the geeks eventually get fitness 10 (super-efficiently exploiting club perks and mentoring). I generally have them eat cooking skill 1-3 foods, which do not trigger the 0-calorie exploit. The athletic twins constantly have max-muscle min-fat, and the geeks are not far off.

  3. My cousin wanted her sim to lose weight so that she could go on a date with someone so we spent a long time trying to get her sim to lose weight, we were starting to give up hope and we almost had to resort to using the CAS menu, but we were still a bit optimistic, then I zoomed into her sims belly and a few seconds later BOOM she got so much skinnier and her face also changed shape, then her sim went on a date, had her first kiss and became the girlfriend of the dude we created for her. The End.

  4. I love this system, not so much the whole game, but the calorie/fitness system is amazing. I didn't know about it, but I had my sim lift, and eat a lot of high calorie foods, never ran on treadmills or anything. I thought in my head "would be cool if my character just bulked up and gained a lot of fat with the muscle, like in real life." Never thought it would happen, then it did and my mind was blown.

  5. Its weird.. one of my sims got fat from his pregnancies and he was a glutton so I think glutton sims gain weight a bit faster, or foodie sims if theyrr not active

  6. I was doing the legacy challenge with one sim and he got SUPER LOADED after getting a promotion and he ate like a king! too bad he also got SUPER FAT as well.

  7. I thought I was just imagining things when I thought my Off the Grid sim seemed to be getting wider after eating free chips at The Sand Bar all the time.

  8. I take loads of screenshots when I play the sims to look back on, and whenever I look at the very start at the screenshots I just think "wow I let my sim go"

  9. Surprisingly, my sims never gain weight. Maybe it’s cause I cheat to make their needs go back to full bar.

  10. It's good to know the blue confetti cake won't really impact my sims weight, because I always have left-over cake in the fridge from the many many birthday's and I don't want my sims to eat that (and only that) for breakfast for their entire life.

  11. My sims that have completed the body building aspiration never seem to get fat however much they eat, unless I use the weight gain ice cream.

  12. One of my Sims, Johnny Zest was always fit. Since he got married and started a family he's been proudly sporting a 'dad bod'. I get him to exercise, but he reverts back after a few weeks. My lazy/glutton sims don't gain weight as quickly.

  13. All my female sims have loads of kids and are always quite fat by the time they die. Probably because I’m on the short lifespan the only thing they eat is cake.

  14. Great video, I didnt know about any of this, I though food in Sims was food and that it didn't matter what it was.

    Here's a question, could a Sim live on alcohol (juice from bars) alone? I've tried to see if you could live on water alone, and I don't think it's possible, unless you get some sort of steel bladder trait, water just doesn't move up the meter much, but the drinks are more, so maybe you could live on drinks alone? I just never got around to fully testing it, I got bored and got regular food for the Sim.

  15. What about babies? I’ve had a few toddlers grow up and be surprisingly large but the baby was only fed when it’s crying and both the parents were fairly fit / thin. Is it random?

  16. its kinda crazy that the game has it's own calorie system. I mean right? That's a detail I'd never expect to think of. I knew about sims gaining weight but I certainly did not know about this.

  17. I’ve taken to having my families live off of salad and eating fruits or veggies from their gardens as snacks. I only wish I could do this in real life! 😜

  18. Now i know why all my sims get fat even though they eat only when hungry😅😅👍amazing in the sims too they need to burn it out 😁 its a game of life thanks for information

  19. Unless they fixed it recently, which I doubt, I know for a fact that all the recipes that came with Get To Work all have zero caleries.

  20. Oh, I thought it only had to do with how full they become. I almost always click away the eating action when they're halfway through a meal, so that the hunger meter doesn't go to the top. But now I know that I should only let my sims eat salad. 👍🏻

  21. My Sims on the Sims 4 aren’t exactly what I would call “fat”, a lot of them just become “disproportionate”. I need a calorie list! This was very helpful. 💯💯🤩

  22. Did the calories get fixed? They’re getting SO. LAZY. In the expansions.

    Also, my kids are always fat when they’re raised from infants. Feeding too much ?

  23. Wow thank you so much, i didnt know that being health body wise was as complicated and difficult in game as it is in real life! 😅🤨😣

  24. the lesson is that you should eat garden salad because it:
    – is filling (but not as filling as spaghetti!)
    – is low-calorie
    – won't burn your house down

    edit: from carl's table, your sim should be eating garden salad and scrambled eggs to stay thin. your sim can eat scrambled eggs if they are super hungry, but they should stick to garden salad otherwise.

  25. in one game I had a sim that I wanted to have no cooking skill, so I made her only order pizza. Even eating only when hungry, she became pretty fat quickly.

  26. My mistake was using the nudge to make my sim's belly a little larger, without making his whole body fat, for more realism…

    After using a lot of gym, my sim is very muscular, but the belly is still large and with abs.

    Horrible. I had to cheat to correct it is cas.

  27. The whole calorie system in The Sims really doesn't make sense. Most of the foods my sims eat have like 300 calories and they need to eat only twice a day most of the time. So their daily calorie intake is 600 calories. A person would be severely malnourished after a while but my sims just get fat af. I hate it.

  28. I never knew that there was a calorie system. But my Sims never got fat because I never wanted to pay money for food so I would just feed them a quick snack every day for whenever they get hungry and it put their food bar up all the way when they just eat a ham sandwich that cost me zero dollars. That’s what I do 🙂

  29. I kinda figured this aspect of the game was based on bad science. Thanks for the confirmation.
    I wonder if anyone has made a low carb mod.

  30. Eat healthy and do cardio to burn fat. Eat more calories to not get too skinny. Lift weights to build muscle.

    In short, it works just like real life.

  31. Hu? I always have my Sims get unnormal skinny over time if I forget to feed them extra (like without them being hungry)! O.O
    I´ve only one time had a Sim go fat by accident and after on or two days of INTENSE jogging, the slim line was there again. 😀
    Maybe it´s because all of my Sims sport around so much… Hmmm…

  32. I like to play an individual sim some times and end up playing them for a while (😬) and I notice they do get over weight after time. I just have them do cardio everyday until I am content with their shape! 😅 i never realized that calories are in this game! I mean of course desserts aren't gonna suffice as a hearty, satisfying meal lol

  33. Had no idea it was that close to real life. I have a love hate situation going on with this right now. lol.
    I usually feed my Sims Garden Salads and Fruit Salad but I have been having them make other recipes, I'll go back to the old days of salad salad and more salad. lol.

  34. My legacy family are skinny without me doing anything. They eat only when hungry and dont gain. Each sim's metabolism is very different tho. I have sims outside the family and they can get fat or whatever

  35. alright; im going to make this quick. Jesus will be back soon and if we don't repent of our sins, we shall be left behind. Please, accept Jesus. He is coming back very soon. Get rid of sin, so you can inherit heaven. Repent, repent, repent!. If you keep on living a lifestlye where Jesus has no place, then you are doomed. It's not even about Hell, it's about being left behind. Please don't be left behind. If the trumpets sound and you haven't risen, I pray that atleast reject the mark of the beast. It will be hard, but it will be your only way to heaven. The time is short, please consider. The Hunger Games are going to start soon. Give your lives to Jesus so that you can be saved. Jesus loves you very much and wants you also saved, so please consider. There isn't much time left

  36. I didn’t know sims could get fat so when I compared my sim to how I originally made her I was like what the heck? How did i not notice for so long.

  37. I know when my sims get pregnant or age up they’ll get bigger but whenever my sims workout they don’t get thinner so idk

  38. I'm curious about something. How did you figure out how many calories each food recipe have?
    Did you have to search in the game files somehow or?

  39. That calorie system is unrealistic to me, I kept my Sim active, let her eat only when hungry and went through a diversity of (gourmet) food. I have a similar lifestyle in real life, eating a diversity of rich food and I'm not getting fat like my Sim! Because I don't eat more than necessary and I stay active. It should work for the Sims too
    Edit: And it's all from homecooked meals! Not even fast food…

  40. Mine never get fat, but the townies do! Sometimes I modify them in CAS to put then back to the original weight, but then after a while they get fat and I never play with them 🤦🏻‍♀️

  41. Once I made a Sim fat on purpose but she automatically kept excersizing. She kept losing weight and gaining muscle even though she wasn't supposed to be skinny lol

  42. I'm guessing maybe the vampires don't gain much of any weight during pregnancy? I had my Sim(not a vampire) marry the vampire girl from the DLC. We had 4 kids and she literally looked exactly the same, slim.

  43. recipe for sims in good shape:
    – never lets the Hunger bar 100% full (more-less 90 is enough)
    – jogging or hour of training every few days (or everyday)
    – low-calorie food (in exaple salads)
    – eat only when hunger bar is (at least) yellow

  44. ppl complaining about a life simulator doing that exact thing it's supposed to do,,,simulate life?? wow we rlly fell this far as a society. jeex
