All vegetarian diets exclude meat of animals. See Plant-Based Diet.

Charles Darwin

There is no fundamental difference between man and the higher animals in their mental faculties . . . The lower animals, like man, manifestly feel pleasure and pain, happiness, and misery.

Nitrogen balance is a measure of nitrogen input minus nitrogen output

Nitrogen Balance = Nitrogen intake - Nitrogen loss

Nitrogen is a fundamental component of amino acids, which are the molecular building blocks of protein. Measuring nitrogen inputs and losses can be used to study protein metabolism.
