Understanding what BMI, BMR, and body recomposition mean can help you a lot in your fitness journey. And, they’re not as “deep” as you might think. But it is quite important to know what all these terms mean, as they can help you understand things about yourself better. 

BMI (Body Mass Index)

BMI is a simple way to calculate your body fat by using your height and weight. It’s a fast way to have a general sense of whether you’re at a healthy bodyweight. Although there’s something about using BMI, it’s a good starting point, but it doesn’t give a 100 percent assurance. This is because it doesn’t differentiate between muscle and fat, so in the case of a muscular person, they might have a higher BMI but still be of good health. 

BMR (Basal Metabolic Rate)

Basal metabolic rate (BMR) is the amount of calories your body burns when you’re not doing anything or just resting. It’s the energy your body requires to be able to do things like breathing, circulating blood, and keeping all organs working fine. It’s affected by some aspects like a person’s age, weight, sex, and muscle mass. The good thing about knowing your BMR is that it can help you understand how to manage your weight healthily, due to how many calories your body naturally burns. 

Body Recomposition 

Did you know that you can change your whole look, physique? Yeah, that’s body recomposition, and judging from the name, you probably know what it’s about. Body recomposition is the process of changing your body composition. It involves building muscle and losing body fat at the same time. You can do this through a combination of resistance training, cardio, and good nutrition. Which can lead to a healthier, more toned physique, even if the number you see when you step on the scale doesn’t change much. It’s all a boy getting healthy and fit. 

Why Does It Matter If You Know What BMI, BMR, and Body Recomposition Mean?

Well, understanding BMI, BMR, and body recomposition can help you make better decisions regarding your health. You can use BMI as a good starting point; to know what’s on ground, learn about BMR to understand your daily calorie needs, and then focus on body recomposition to build a strong and healthier YOU. Or get the body of your dreams. However, keep in mind that it’s always about progress, not being perfect. Self-improvement will always be a process and a journey, but along each checkpoint, you’ll realize how far you’ve come.
