Estimating your basal metabolism
The basal metabolism is the energy that the organism needs to sustain the body at rest. This includes breathing, making the heart beat, regulating body temperature, repairing tissues, sleeping, the functioning of the liver, kidneys, etc. It is the energy necessary to maintain the vital functions of the body and it represents up to 70% of the calories we burn in a day.
When we say that the basal metabolism of someone is high, it means that the quantity and the speed at which calories are burned in order to answer the needs of vital functions are high. The quantity and the speed at which calories are burned by the basal metabolism will vary greatly from one person to another.
Factors that influence the basal metabolism :
- Sex (women tend to have a slower metabolism than men, by about 10%)
- Age (tends to decrease with age)
- Body fat percentage (a fat person will have a slower metabolism)
- The practice of repeated restrictive diets (they are said to lower basal metabolism)
