We have often come across terms like BMI and BMR to calculate the ideal weight for fitness gurus. But what do these terms really mean? How do they affect our weight loss goals in any way? Here is what you need to know about these two terms of physical fitness.
When we talk about BMI, we are referring to your body mass index. It is a scale that helps indicate the composition of body fat. BMR on the other hand is the basal metabolic rate, which is a measure of how much energy our body needs to take care of important functions that are at rest. Their BMI and BMR are associated in the sense that the higher the body composition, the higher the BMR.
How to calculate the BMI?
Calculating your BMI is a fairly easy thing to do. You will need to divide your current weight in kilograms by your height in inches squared. An example would be: If you are 5 feet 10 inches, and your current weight is 175 pounds, your BMI would be approximately 25.1. You can also take the help of an online calculator for this.

How to calculate the BMR?
Calculating your BMR can be quite a difficult process. The formula used for BMR is different for both sexes. One of the easiest and simplest ways you could calculate your BMR is by using the calculator available online. The result you get will indicate how many calories your body needs to perform some of the most basic functions, such as breathing, digesting food, and doing daily activities. BMR also depends on your physical activity during the day. You have to use an equation for this. One of the most famous formulas for calculating BMR is the Harris Benedict equation. It was developed in 1918. It was subsequently revised in 1948, which gave better results.
What is the difference between BMI and BMR?
The body mass index or body mass index has been called a statistical measurement of a person’s current body weight. However, it is based on both height and weight. It has often been used to determine what someone’s ideal weight should be. BMR, on the other hand, is a person’s basal metabolic rate, which is the amount of calories a person should consume every day, even if they haven’t done much, other than lying in bed doing nothing.
A person’s BMI tends to stay the same most of the time. As long as your height is the same, your ideal weight will be in the same category. In fact, BMI is an indication that helps you lose and / or gain weight and / or build muscles. Your BMR in hand will decrease with age. As you get older, the metabolism rate will actually start to slow down. This makes it difficult for you to eat what you like and still stay slim.
There are other things that slow our metabolism down too, like eating unhealthy foods. If your body expects you to stay within a certain amount of calories, depriving it of that will put you in crisis of different kinds. So if you really eat less, the metabolism rate in your body will decrease. Yes, if you continue to eat in smaller amounts, chances are you will start to see rapid weight loss. However, once you start eating regularly like you did, you will lose weight faster than you thought.
However, a good exercise regimen can help increase your basal metabolic rate. Bodies in constant motion need a large amount of food to stay healthy and fit. Do you have any idea how many calories athletes regularly need to keep them running? When you start to increase your activity, your metabolism increases instantly and the amount of fuel your body requires also increases. So if you want to keep fit, stay active and eat healthy.
