I like the Sims I play with to be slim, generally. I didn't realize food in this game had calories until a couple weeks ago, and I could not figure out for the life of me why every single Sim in my family had become not just fat, but obese, even though I had them exercising. The father had recently begun rapidly advancing through the culinary track, and I had his family eating whatever (generally rich) recipes he made... helped him in his career, so why not? Turns out maybe it was not such a good idea...
The father has since died, but all of his descendants have been banished to eating salad forever.
