I was also thinking that protein is a fairly scarce nutrient.
Meat has about 20-25% protein by weight. So you would have to
eat like 2 kilos (4.4 pounds) just to get 1600-2000 Calories,
assuming fat is negligible. I'm not sure if the problem comes
from fat deficiency, pure starvation, or having to eat such a
huge amount of food overloads the digestion...

The 93% refers to protein and WATER weight. 72% water in
this case. The meat has 7% fat by weight and 21% protein.
