Is there a bug with the Fast Metabolism trait from the Fitness aspiration? You're supposed to gain fitness quickly, but it seems like you lose it just as quickly, which seems counterproductive. I'd check the tuning, but I don't even know where to start...

Theoretically, that make sense to me. A better processor is a better processor for better or worse.

Anyway, rumor has it that weight game is bugged to start with, so I'd expect some related effects.

My understanding is that it makes your body change quicker, period, for better or worse.

Yeah, there was something in the Sims 3 that did the same thing. Faster fitness gain and weight loss, but also faster weight gain as well. And considering how stupidly easy it is to get fat in this game, I'd say it'd be very noticable.

Faster weight gain from faster metabolism would not make sense. It would be harder to gain weight because you are burning calories faster. Faster gaining muscle mass would not make sense either. Easier to get defined yes, but that is just because you burn fat easier. Not because of muscle gain.

EDIT : The confusing thing here is EA calling the fat slider 'weight' . Because gaining muscle mass increases your weight too.It i just that an ounce of fat is more volume then an ounce of muscle. So gaining weight through fat is a lot more visible on someone's body.
