. . at least half the weight of a pig foot is bone, which, contrary to what some here believe, I do not eat (and if I did bone isn't fattening).
Pigs feet take some effort to eat so you can't just scarf them down, and they're quite satisfying so they reduce my hunger for snacking on other stuff too.
Also, a week is 7 days, not 5 so "more than a week" would be .625 pounds per day max, or about .312 pounds actually consumable.
