Weight Issues with Sims

I've had this happen before, but it seemed to go away with one of the older patches/updates. Most recent update though, it's back again. I know the food Sims eat has calories, and too many sims calories + little to no exercise will result in a Sim gaining weight. I've had it happen to Sims before, but it's always been over a period of time and not, as has been happening again recently, a Sim literally going from their standard size to double that size in a period of less than 3 days, when a) The house is played rotationally and you've had no actual control over them for 3 sim days to make the eat their way through several fridges worth of food, and b) You see them out and about exercising at various gyms. At least this time it's not as bad as Sims doubling in weight after a single meal, but even so, I don't expect a rotationally played household to suddenly double in weight size in the 2-3 Sim days I'm not actively playing them.

Anyone else having this issue?
