Question

Quizplus · Accepted Answer

An RER value of 0.70 indicates that the body is metabolizing pure fat, as fat metabolism produces more carbon dioxide and less oxygen than carbohydrate metabolism. An RER of 0.85 indicates a mix of fat and carbohydrate metabolism, while values above 1.00 indicate anaerobic metabolism. Therefore, an RER value of 0.70 is the best choice to indicate metabolism of pure fat.
