Around 70% of the calories that are consumed by a person is used up for basal metabolic activities. Those undergoing high-intensity interval training will also have higher BMR rates.įor those who are trying to lose weight or plan to maintain their current weight, knowing the BMR is an important step. Weight training: High volume of muscles in the body tend to increase the BMR for the long-term.Menopause: Those going through this phase, will have their BMR values at a lower level, as they will be burning fewer calories.Age: The BMR values will usually decrease with age, which means that people may need to adjust their diet as they get older in order to avoid weight gain.Some factors can influence the BMR of a person and they include the following. The body composition of a person which involves the proportion of inert body fat and active protoplasmic tissue is an important factor in measuring BMR.
The equations have been revised since their origin, to account for various factors and are stated below.įor Males, BMR= (88.4 + 13.4 x weight in kilograms) + (4.8 x height in centimeters) – (5.68 x age)įor Females, BMR= (447.6 + 9.25 x weight in kilograms) + (3.10 x height in centimeters) – (4.33 x age) BMR is basically the minimum energy exchange that occurs in the body to support activities like respiration, circulation and secretion.Įven though there are a number of formulas, BMR value is often calculated by the Harris Benedict Equation which is different for men and women. Since most people gain weight due to a mismatch between the daily energy consumption and energy expenditure, the minimum daily energy requirement for a person is to be determined.Īpart from body composition, sex and age, it has been recorded that height is an important factor in determining the metabolism rate and taller individuals generally have higher rates. The reduction in physical activity due to lifestyle choice has resulted in obesity becoming a vital health issue. Even though it is a good starting point, BMI has to be taken into consideration with other factors. It is being stated by health experts that BMI alone is not to be identified with good health or the risk of cardiovascular health, blood sugar or blood pressure. Some studies have also found that even though people with a slightly higher BMI run the risk of a few diseases, they tend to live longer than those with lower values. There are various factors including food and lifestyle choices that influence health and there are many individuals who are disease-free even with a high BMI. At the same time, BMI is not an indicator of any particular disease or a psychological condition. Many individuals who had a high BMI reportedly felt better, both physically and psychologically once they reduced their weight by some kilograms. High cholesterol and related cardiac ailments.While BMI is not accurate for those who are pregnant or have a high muscle mass, a high value can be linked with certain diseases related to obesity. While the values between 18.5 and 25 are considered normal, a person with a BMI between 25 and 30 is considered overweight and a person with a BMI over 30 is considered obese. The values obtained to determine the state of a person. In case one is using the English system, then the pounds should be divided by inches squared and the result has to be multiplied by 703. To calculate BMI, the person’s weight in kilograms is by height in meters squared. The method does not measure body fat directly but it correlates with other techniques for measurements of body fat. BMI calculation and importanceīMI is calculated based on a person’s weight and height in order to determine whether he or she is underweight, normal weight, overweight or obese. These values are important for people who are looking to achieve specific fitness goals or aiming to reduce weight. In many cases, the Total Daily Energy Expenditures (TDEE) is calculated for individuals where an activity factor is added to the BMR value. The calculation of BMR is more complex than BMI and involves an individual’s height, weight, age and gender.īMR is the amount of energy that is expended in activities like breathing, keeping the heart beating, blood circulating, digesting food and delivering their nutrients to cells, without doing any other external work. So those with higher than average muscle mass can also have a high value of BMI even if they are not obese. What is the difference between BMI and BMR?īMI is often linked with obesity and a higher value also increases the risk of certain diseases.īut BMI does not distinguish between body fat and lean body mass and does not take into account the physical location of body fat.
