BMR measurement

The basal metabolic rate is the amount of energy (in calories) that your body requires per day in sustaining vital life functions such as breathing, pulse, and body temperature at rest.

Calorie counts vary from person to person. Basal metabolic rate measurement requires you to lie down and breathe through a breathing mask to determine oxygen uptake for around fifteen minutes.

This test is used as a basis for individually tailored diet plans and specifications for calorie intake, whether for weight loss or obesity prevention.

Duration of the test, including consultancy (optional body fat measurement)
about forty-five minutes
