Was King Kong constantly hungry?

My calculations tell me that he had to be hungry: the island could not produce enough food for Kong.

Here I explain why:
Ewalt (2005) calculated that Kong would need 3 400 kg of food per day. A normal gorilla needs 3 km² of territory, and Kong, 100 times heavier, would require 300 km², probably too much for the island we see in the map (even if we do not consider the fact that at some time there had to be more gorillas; shown only in the 2005 version).

We could try to solve this by saying that the natives fed Kong, but again, even if he ate the poor sacrificial victims, there was not enough nourishment there.

  
No hypothetical changes in Kong’s diet or the plants around him can make their populations viable on an island small enough to be missed by cartographers in the early twentieth century.

But certainly Kong could have bitten anything he wanted, look at what is inside the mouth of a male gorilla:

And finally, the food topic brings me to the question: 
Why did the natives offer Kong women: did he eat them as a diet supplement?

We'll see the answer in the next post.
