Compared to vegetable matter, meat is relatively easy to digest. Much of the digestion of meat takes place in the stomach before passing it to the small intestine where nutrients are absorbed.

In addition, the herbivore's longer intestine increases the amount of surface area available for absorbing the extracted nutrients.
