John, with humans it's been pretty well demonstrated that, contrary to "expert" government advice, eating natural fat does not make you fat. Sugar, processed fats such as corn oil, and simple carbs are the culprits.
If this holds with fish, perhaps fat prey fish don't make predators fat. It would be interesting research!
Where does the government say eating natural food makes you fat? I am not aware such and need to be if it exists.
