Metabolic testing measures what you burn:

• RMR: your resting metabolic rate. This is the number we measure that is unique to you. It is the number of calories you would burn if you sat in a chair all day long.
• Lifestyle: your RMR is used to calculate how much more you probably burn by your simple daily activities of walking, eating, driving, etc.
• Exercise: RMR is used to calculate how many calories you would burn if you exercised moderately for 30 minutes
