BMR CALCULATOR – BASAL METABOLIC RATE CALCULATOR
The BMR is a short form for “Basal Metabolic Rate.” This refers to that specific number of calories required in order to keep the body functioning at rest. As a result, any increase to your metabolic weight (e.g. exercise) can increase your basal metabolic rate. So, the BMR calculator calculates the BMR based on well-known formulas. You can use this calculator to determine your caloric needs, and gain or lose weight. A key reason why you might need to know your BMR is that with the knowledge, you get to calculate the calories you burn daily.
There are three equations adopted in the calculation of BMR, and they include;
- Mifflin-St Jeor Formula:
Women: BMR (Basal Metabolic rate) = 10W + 6.25H -5A – 161
Men: BMR (Basal Metabolic rate) = 10W + 6.25H -5A + 5
- Katch-McArdle Equation:
BMR (Basal Metabolic rate) = 370 + 21.6(1 –F)W
- Revised Harris-Benedict Formula:
Women: BMR (Basal Metabolic rate) = 9.247W + 3.098H – 4.330A + 447.593
Men: BMR (Basal Metabolic rate) = 13.397W + 4.799H – 5.677A + 88.362
W = Body weight (kg)
H = Body height (kg)
A = Age
F = Body fat (%)
BMR (Basal Metabolic rate) Variables
- Age: BMR reduces as one gets older, meaning that the older the age, the lesser the Basal Metabolic Rate. Likewise, the older the age, the lesser the caloric intake that is required to maintain the functioning of their organs at a particular level.
- Diet: The basal metabolic rate, BMR can be increased through small, routinely dispersed meals. Here is the point, starvation can lessen the basal metabolic rate by as much as 30percent.
- Muscle mass: do you know, that when you involve in aerobic exercises such as running, jogging or cycling, your BMR is not affected? But when you involve in anaerobic exercises which includes weight-lifting, can lead to an increased BMR due to the fact that it builds muscle mass. As the muscle mass in the physical composition of an individual increase, the higher the basal metabolic rate, BMR that will be needed in order to sustain that individual’s body at a particular level.
- Genetic traits: The basal metabolic rate, BMR is influenced by the hereditary trait which is passed down from one ancestor to the forthcoming ones.
- Pregnancy: The basal metabolic rate, BMR increases while ensuring the livelihood of a separate fetus internally. This is an important reason behind the fact that women that are pregnant tends to eat more than normal. Also, depending on hormonal changes, menopause can either decrease or increase BMR.
- Weather: Due to the energy required to create a homeostatic body temperature, cold environments tend to increase BMR and also, too much of external heat can increase the basal metabolic rate as the body uses up energy in order to cool off the internal organs.
- Supplements: Caffeine is a popular supplement that tends to raise BMR, mostly in order to fuel weight loss. Some drugs or supplements tend to increase the Basal Metabolic Rate.
Every individual tends to use up energy irrespective of whatever they are doing. Energy is even being used up during sleep. If you decide to stay in bed all day, the BMR calculator will help you calculate your basal metabolic rate.
Another important thing to take note is that the basal metabolic rate, BMR decreases with age. Also, when you deprive yourself of food, you tend to reduce your BMR. A way to increase your BMR is through the frequent routine of cardiovascular exercise. This can also enhance your fitness and health when the ability of your body to burn energy steadily slows down.
