Resting Metabolic Rate Testing

Using Indirect Calorimetry
Struggling to lose weight?

Resting Metabolic Rate testing assesses the number of calories your body requires at rest to help determine the number of calories you require to meet your weight goals - weight loss, maintenance or gain.

Research has shown that for overweight and obese adults, formulas that predict RMR to within ±10% of the measured value were only accurate 40% of the time, regardless of gender and weight classification. In medical weight management settings, direct measurement of an individual’s RMR should be considered, especially when standard modifications to diet and lifestyle produce limited weight loss, a plateau or weight gain.

Resting Metabolic Rate Testing

What is Metabolic Testing?

Indirect calorimetry devices are the 'Gold Standard' in measuring Resting Metabolic Rate (RMR). The test involves breathing into an indirect calorimetry device for approximately 10 minutes after having rested. The test is non invasive, and is safe for anyone to use. By comparing the quantity of oxygen and carbon dioxide inhaled against exhaled, the device accurately calculates your Resting Metabolic Rate (aka Resting Energy Expenditure).

Is Metabolic Testing Right for you?

You may want to have a metabolic test done if...

  • You are on a 1000 - 1300 calorie meal plan but have not lost any weight.

  • You are weaning off of Ozempic, Saxenda, Rybelsus or Mounjaro.

  • You have lost weight and are now transitioning to weight maintenance.

  • You had bariatric surgery and your weight has plateaued >2 months.

  • You are working with a physician, dietician or personal trainer and they have recommended it.

  • You have certain medical conditions such as severe obstructive sleep apnea, Cushing’s syndrome, Grave’s disease, Hashimoto’s disease, subclinical (untreated) Hypothyroidism and a physician has specifically requested to test your metabolism.

Test performed by Dr. Fraser Barnes, MD of Thames Diagnostics at Sky Medical Clinic. Appointments are available on weekends and certain mornings and evenings during the week.
