In order for sims to keep their weight roughly in check without the need for constant workouts, I added a small loot action to the asleep buff. Every time your sim is sleeping, they'll lose a tiny amount of fatness to simulate a natural metabolism.


In the past, I heavily relied on CandyD's Balanced Calorie Mod, but it is outdated. Several modders have taken it upon themselves to keep it updated, but afaik all stopped doing so. I took a look at the files and immediately understood why. The Balanced Calorie Mod consists of more than 500 tuning files that need to be changed and then re-checked after every update. It was then I decided I'm never doing this. So I wanted to find an alternative way to make sims burn calories without having to workout.

Using MC Command Center I tracked a sim family's fat value over time and found sims gain on average 1.62 fat points per day if not exercising even though they are not overeating. I choose to deduct 1.62 fat points every time a sim is sleeping to counteract this.

Obviously, how much a sim is gaining depends on a few factors, mainly how many calories their food has, so this mod needs to be tested under all kinds of circumstances to see whether 1.62 is the best possible value to use. It stabilized the sim's weights nicely in my game, but depending on play style, your experience may vary.

For whatever reason the loot action I created doesn't accept small values for fat loss, resulting in absolutely nothing happening. To work around this I had to set a higher number, namely -22.62, and then make them gain +21 fat points at the same time resulting in the desired value of -1.62 fat points. However, this means sims cannot reach a fat value of -100. The lowest they'll go is -79. Generally, this is not a huge problem, because at -79 fat, sims are already very skinny and the difference to -100 is hardly noticeable.
