BMI Calculator

Your body mass index, usually referred to as your BMI provides a snapshot of where you are in terms of healthy weight. Your BMI is just a guide, it gives you an idea of where you now, and where you are in terms of healthy weight for your height. So if you are currently overweight, you can see how many pounds you need to lose before you fall into the normal weight category.

 

A BMI score of less than 18.5 means that you are considered to be underweight, which can cause problems for your health. A healthy weight is important when fighting infection, or even when trying to avoid the common cold. If your BMI score is between 18.5 and 25, then you are classed as having a normal weight. For more people, this is where you really want to try to aim for when deciding how much weight you need to lose.


A BMI score of over 25 means that you are overweight. If you fall into this category, then you really need to be careful, but you can still be reasonably healthy. However, it is vitally important that if your BMI is over 25, then you need to work hard to bring your BMI score down so you fall into the normal weight category.

Reducing Your BMI Score

If you are worried that your BMI score is too high , then the main thing that you need to do is become more active, while learning more about your nutritional needs, and how the food you eat affects your body fat to lean muscle mass ratio (which is basically what BMI means)Once you become more active, and you understand the role that food has on your BMI, you will find that it becomes easier to maintain a healthy weight. The key to losing weight, and reducing your BMI score is to maintain a balanced, healthy, active lifestyle.

BMI & How Your Health Can Change

I used to have a very high BMI score, as I weighed 300 pounds, so my BMI score was 36.5, which is severely obese. My current BMI score is 23.6, based on my weight of 194 pounds, which falls within the normal weight range for my height (6' 4" tall). You can find out how I managed to control my weight, and how I lost 100+ pounds, this will give you an idea of how you can succeed. When I used to weigh 300 pounds, my mobility was severely reduced, I could barely walk a mile. Now that my BMI is down to below 25, I can easily run a 10k.

BMI Limitations

The BMI scoring system does have some limitations, so should only be used as a guide, and not an absolute reference to your health. A tall muscular man will have a higher BMI. The way BMI is calculated may overestimate body fat in those with higher levels of muscle mass. So an athlete with lots of lean muscle mass could be classed as overweight, which is obviously incorrect. A more damaging limitation of the BMI scoring system is for those people that have lost muscle mass, through the ageing process, or those that are on an extreme diet. For these people, their BMI may underestimate body fat because of the loss of lean muscle mass.

What Is Your BMI Score?

Your BMI or Body Mass Index gives you an idea of where you are in terms of how healthy your weight may be at any given time. Your BMI score shows you if you are underweight, a healthy weight, overweight or obese for your height. If your BMI score is over 30, then you fall into the obese category, this is where your health can really suffer, and you need to be aware of the health risks associated with obesity.

Does It Matter If My BMI Is High?

The problem with BMI is that it only takes into consideration your height and weight, but not your body composition. This means that those that are very muscular may have a high BMI score, and could even be labelled as obese, even though they are very healthy.

Why Is My BMI Score Important?

Your BMI score gives you an idea of where you are in terms of healthy weight; it can tell you how close you are to your ideal weight. Your BMI score is important as it can provide important information about how much fat your body is storing; this is true for the majority of adults, with some exceptions.

Is My Health At Risk?

If your BMI score is higher than 25, then yes, your health could be at risk. It is important to make sure that you are always eating a balanced diet. Your activity levels should also be increased when your BMI is higher than it should be. You really need to try very hard to have a BMI in the normal, healthy weight category. Walking is a good way for you to increase your activity levels, and moving up to running as your fitness improves.
