WHAT IT MEASURES
Your real energy requirement, measured not estimated
Indirect calorimetry measures how much oxygen you consume and how much carbon dioxide you produce while lying still. From that, we calculate what your resting energy expenditure is and whether your body is burning carbohydrates or fats.
Resting Metabolic Rate
Calories burned per day at complete rest, measured rather than predicted from height and weight.
Measured vs predicted
How far your real rate sits from the standard equations, which is where most calorie targets go wrong.
Metabolic substrate use
Your respiratory exchange ratio, which shows whether your body is currently primed to burn carbohydrate or fat at rest.
Daily calorie targets
A maintenance figure plus deficit and surplus ranges built from your measured rate and activity.
WHO IT IS FOR
Who books an RMR test
Fat loss that has stalled
You are eating what the app says and nothing is moving. This shows whether the target was ever right.
After significant weight loss
Metabolic rate falls with weight loss. This quantifies the drop so your targets stay accurate.
Athletes and hard trainers
You need to confirm you are eating enough to support training and recovery rather than under fuelling.
YOUR VISIT
What happens on the day
A thirty minute appointment. You lie still and relaxed for the test while breathing normally through a mask or hood. No effort required.
01
Settle and setup
Ten minutes lying quietly so your body reaches a true resting state.
02
Measurement
How to prepare. Fast for four hours, no caffeine or nicotine for four hours, and no exercise for twelve hours. Come rested. Morning appointments give the most consistent results, and it pairs well with a fasted DEXA scan.
Ten to twenty minutes of relaxed breathing while we analyse your expired air.
03
Targets and debrief
We compare measured against predicted, set your calorie and protein ranges, and upload the report to your dashboard.
