Ghrelin a marker for Respiratory Quotient

Respiratory Quotient is a calculation that determines which substrate (fat or carbohydrate) is currently being burned. It is a complex process that involves measuring oxygen inhaled and carbon dioxide exhaled and must be performed in a laboratory.

This study showed that plasma ghrelin (a hunger hormone) is a sensitive marker for RQ, and a heck of a lot easier to measure.
