Others, such as genetics, pregnancy or the use of stimulant supplements also have an impact on metabolic rate. While these are the most important factors, they are not the only ones. On the other hand, a significant reduction in food intake sustained over time can reduce BMR, because the body interprets that it is in a period of scarcity and therefore minimizes expenditure to ensure survival. Food - Eating small amounts regularly throughout the day is considered to have some impact on metabolism (but not on BMR, since BMR is calculated in the absence of digestive processes), since it activates the digestion mechanism more frequently, and thus leads to higher energy expenditure.Thus, if the external temperature is considerably reduced, the body will expend more energy to maintain the body temperature in the range in which it normally is, and the same happens if the external temperature increases excessively. Temperature: External temperature conditions metabolic expenditure, since the organism reacts to temperature variations by making adjustments that allow it to maintain a balance.This means that an individual who has more muscle mass needs more energy to maintain his body than another whose musculature is less developed. Muscle tissue requires high levels of energy for its maintenance, so considerable muscle development means a higher energy expenditure for the body. Muscle Mass: the level of muscle mass is of critical importance in measuring metabolic expenditure.Weight and Height: weight and height are used to determine what is known as Body Surface Area, which is a very reliable indicator for measuring metabolism.

In a certain way, this factor is also linked to the previous one, since muscle development is more pronounced in younger individuals than in older ones, who, due to the decrease in testosterone production that occurs after a certain point in time, find it more complicated to keep muscle mass.

Age: age also has an influence, since older individuals need less energy than younger ones.

Sex: sex is a conditioning factor, hence there is one formula for men and another for women.

The aspects to be considered that have an impact on BMR are the following: Should be calculated from time to time in order to have an accurate knowledge of the current reality. Factors Influencing the calculation of BMR (Basal Metabolic Rate) It consists of the following equation:īMR=370+(21'6 x Lean Mass). The Harris Benedict formula, published in 1919 and later revised in 1984, is the following:īMR= 88.362 + (13.397 × weight in kg) + (4.799 × height in cm) - (5.677 × age in years) (Men)īMR= 447.593 + (9.247 × weight in kg) + (3.098 × height in cm) - (4.330 × age in years) (Women)īased on this formula, which was later revised in 1990, the Mifflin-St Jeor formula was created.īMR = (10 x weight in kg) + (6.25 x height in cm) - (5 x age in years) + 5 (Men)īMR = (10 x weight in kg) + (6.25 x height in cm) - (5 x age in years) - 161 (Women)Īnd finally, another formula, even more accurate, is the Katch-McArdle formula, which is the only one that takes into account the percentage of body fat, and which also works for both sexes. In this calculator you can choose the one you prefer. There are several formulas used for this purpose.
