Wow, do they really gain weight based on what they eat? I started wondering about that when all of my sims starting getting really overweight, and I have to keep them exercising all of the time, which is really annoying. I hate going to the gym in real life enough already!
Looks like it's Garden Salads for my sims from now on...
That's unfortunate, though, I love having them make a wide variety of dishes for fun.
