Ah, you're talking about the shoreline-theory. I'd forgotten about that one. It seems to be a sort of compromise between the aquatic ape and the standard theory. Still, I do know of plenty of Palaeolithic sites which are based far inland(albeit probably never too far from rivers).

 

Last I checked, seafood is generally viewed as very lean. The only exception are deepwater fish but those presumably wouldn't have been caught in palaeo times, given the lack of ships, until recent times.

 

Re claims:- The claim that in palaeo times, there were large mammals with higher fat-content which then died out isn't relevant, really. For one thing, wild horses and wild aurochs(the ancestors of modern cattle) were staples of the Palaeolithic diet, at least in Europe, and they are still around today with the same levels of fat(if grassfed).
