Also known as indirect calorimetry, it is used to have an exact measurement of caloric or energy expenditure at rest, with which it is possible to identify the patient’s true need for calories, in addition to knowing the type of metabolism they have (slow, conventional, or fast). ). 

In this way, the nutritionist has great tools to develop a specific diet for each patient considering their caloric needs and the type of food needed for the planned goal, always including a physical activity plan.

Calorimetry at rest is often used to:

Establish proper body weight: 

  • Important part of therapy against overweight and obesity.
  • When there is significant weight loss whose cause is unknown.
  • To control the weight of pregnant women or during lactation.
  • In growing children.
  • Cases of muscle mass loss or sarcopenia in older adults.

Regulate physical activity:

  • Bring body composition to optimal parameters.
  • Diet prepared according to the requirements and caloric expenditure. 

This study does not present any risk, it takes between 15 and 20 minutes and its results are precise and of great help to determine the appropriate treatment for each patient.

It is necessary that you have at least 12 hours of fasting without having done any physical activity in that period. 

In the Pulmonary Physiology and Inhalation Therapy Department we guarantee you the best care in respiratory ailments provided by highly trained medical personnel.
