This model seems to be reducible to "people will eat what they prefer".
A good model would be able to reduce the number of bits to describe a behavior, if the model requires to keep a log (e.g. what particular humans prefer to eat) to predict something, it's not much less complex (i.e. bit encoding) than the behavior.
No, because preferences are revealed by behavior. Using revealed preferences is a good heuristic generally, but it's required if you're right that explanations for behavior are mostly post-hoc rationalizations.
So:
People eat what they prefer. What they prefer is what they wind up having eaten. Ergo, people eat what they eat.
Consistency of preferences is at least some kind of a prediction.
