6.  Law of Conservation Of Mass [Optional - Default: Enabled]
     The Law of Conservation of Mass applies to sim weight gain: Sims cannot
     revert to being fat if not given food. They must actually eat in order
     to gain weight.

"Law of Conservation of Mass" only applies to sim weight, not sim fitness. Even though it is default enabled my sim still does experience a jump in fitness from 1.5 to 1 while exercising.

Is it possible to have a feature of Consort's core mod integrated with Awesomemod? I.e. extending the EA standard fitness/fatness values from -1/1 to -2/2. I'm not talking about extending the slider values but more of preventing a sim with a fitness of 1.5 snapping back to 1 by exercising.

Here's a link to Consort's mod: http://modthesims.info/d/470349

Right after I read this thread I also got the bug. So what did I do? I ignored it and continued my normal playing. But I have to say there have been only two situations like this. And also when the sound returns, it does have a deafening effect.
By posting this I probably jinxed it.

I remembered there was a mod like that at Mod The Sims.

Btw you're not the only one who is sick of those calls and would rather let them die.
