Why Measure Your Metabolic Rate Rather than Use Predictive Formulas?

The Resting Metabolic Rate (RMR) is the rate at which the body burns energy when it is at complete rest. It indicates the number of calories the body needs to perform basic functions like breathing and circulation.

Predictive formulas have long been used to "measure" the RMR because an actual measurement through Indirect Calorimetry has not been practical. But the truth is, while predictions might hold their ground statistically, when applied to individuals, they are woefully inadequate.
