With this mod, Sims in a currently played family lose their fitness. The fitness decay depends on the age and the fitness level of a Sim. It's base-game compatible, I hope.

This mod consists of two parts: core that runs the decay and config that contains settings of the decay. You need both parts to make this mod work.

How this mod works
The fitness meter can have values from 0 to 1000, where 0 means the fittest and 1000 means the fattest. When a currently played family is at home or on vacation, every 4 hours a certain value is subtracted (notice that two minuses make a plus) from a fitness meter of each Sim (see above), according to the table below.



Toddlers aren't affected. Additionally, if a Sim is thin+ to obese, and is being hungry (having filled at most 25% of the hunger need bar) while the fitness decay process is running, they lose extra 2 points, which means they lose their weight.

The above values are used in the standard version of the config file. The available versions are:

• standard;
• slow – decay every 12 hours;
• noFatness – thin+ to obese Sims aren't affected by the decay (they can lose weight by hunger though);
• noFatness-slow – a combination of noFatness and slow versions.

Choose only one config file. You can also create your own version by editing the behavior constant from the config file in SimPe.

Fitness thresholds changes
simNopke-fitnessThresholdsChanges is a stand-alone mod that prevents Sims from losing their musculature or gaining weight shortly after workout.

Originally, a Sim gets fat if their fitness meter value is over 666 (the fit bar), gets thin if it's between 333 (the fat bar) and 666, and gets fit if it's lower than 333.

With the mod, a fit Sim has to reach more than 348 points (slightly under the fit bar) to get thin, and a thin Sim has to reach fewer than 318 points (slightly above the fit bar) to get fit. A fat Sim has to reach fewer than 651 points (slightly above the fat bar) to get thin, and a thin Sim has to reach more than 681 points (slightly under the fat bar) to get fat.

Other fitness-related mods you should know

• Fit Fixes by Argon
• M&G Physiology Fix by gummilutt
• Exercise Tweaks by Cyjon
• Fitness For All by Pescado
• Slower Fitness Gain (v2) by simler90

They're all compatible with this mod.
There is also a Cyjon's mod called Fitness Delta Fix but it's useless since the game ignores custom fitness limits anyway.

Conflicts
None that I know of.
