Generally, if you want to measure your basal metabolism, you can perform the basal metabolic rate by estimation method. The basal metabolic rate is the level of basal metabolism measured per unit of time. The estimation method is a relatively simple method and is often used in clinical practice. The estimation formula is: pulse rate + pulse pressure – 111, where pulse rate represents the pulse rate and pulse pressure refers to the systolic blood pressure minus the diastolic blood pressure. If the estimated metabolic rate is less than 15%, the basal metabolic rate is low; if the estimated metabolic rate is greater than 20%, the basal metabolic rate is high. It is important to ensure that you are fasting before the measurement and that it is done in a state of non-exercise, non-illness, and normal room temperature, as these factors may affect the results of the basal metabolic rate measurement. Personal measurement may not be accurate enough for general reference. If abnormalities are suspected, it is recommended to consult a doctor for a definitive diagnosis and prompt treatment.
