Actually, I would not recommend an outdated mod if it hasn't been updated to the latest EP. That mod looked like it hasn't been touched or updated since 2005. That's 4 years...
Pescado does have a better version: No Eat Crap II available at
MATY with less talking and a more logical approach to how much a Sim will eat food based on personality and state of fitness among other things.
He made sure it is updated or compatible with the latest EP. Try that mod instead and let us know if this is exactly what you're looking for.
