Hmm. The Fucking Manual is not very specific.
CHANGES:
Sims (who are not fat or lazy) will no longer stuff themselves until they
explode. Lazy and fat sims will continue to eat everything and thus can
still become fat, because sometimes, you just want fat people. Sims who would
not eat out of a trash can will cease eating food that has gone spoiled.
Sims will talk considerably less when eating, especially if they are in a
hurry (because they're tired, starving, need to pee, have more orders), or
if they're eating without the benefit of chairs.
I'm guessing that twp points would be few enough. That's pretty lazy.
