Body Mass Index Calculator

The Body Mass Index (BMI) is the easiest way to determine if you're carrying around too much fat. It's based on your height and weight — and estimates whether your weight is healthy or if you are overweight or obese.

To get your BMI, enter your information below and then click calculate.

Your BMI is

A healthy BMI for adults is between 19 and 26. A BMI of 27 to 30 is considered overweight. Obesity is classified as a BMI of 30 or above.


If your BMI is below 19, you may be at risk for problems such as osteoporosis. A low BMI may also be a sign that you are ill. If your BMI is in the overweight or obese range, you are at greater than average risk for conditions such as coronary heart disease, type 2 diabetes, and high blood pressure.

Result notes
BMI values apply to adult men and women, regardless of their frame size or muscle mass — with the following exceptions: competitive athletes, body builders, pregnant or nursing women, and frail or sedentary elderly people.

If you think your BMI results do not accurately reflect your body fat level, tell your doctor about your results and ask for a body fat test.


Body Mass Index

Body mass index is an estimation of body fat versus lean muscle mass. The calculator takes two proportions into consideration; height and weight. The taller someone gets the more stretched out they become thusly these people have a nice even distributation of fat to lean muscle. Having too much fat can have dire consequences in relation to your health as would not having enough fat and/or lean muscle mass can be detrimental to someone's health on the other side of the coin. In some people it is easy to see if they are overweight or obese and carrying around all the weight is hard on the body. The heart and lungs have to work harder, people are more prone to hypertension,stroke and diabetes when they are overweight. Some of us it is not so easy to see and by looking at me for example people assume that I'm a healthy weight, well in fact I'm overweight by 5lbs. Wow, 5lbs, who cares right? Well, the fact of the matter is that it is not so easy to tell. Just because people are overweight or obese doesn't mean they are not trying to lose weight. The myth about weightless is this burn more calories and eat less calories and you'll lose weight. That's not entirely true and companies have made big bucks selling you this cock and bull story. A calorie is not the same as every calorie out there. For example a calorie in vegetables is not the same as a calorie in a chocolate bar. Let's assume for a minute that I have a carrot in one hand and the carrot I hold is 100 calories. Now in the other hand I have a chocolate bar just a regular everyday chocolate bar, nothing special and that chocolate bar is 100 calories. If I had given the carrot to someone to eat only a 100 calorie carrot 3 times a day for a year. Yes I do see the flaw so far, who can live on 300 calories a day? I know, just follow along it's all about the numbers and the science. I give the 100 calorie chocolate bar to someone else to eat only that 3 times a day for year. With the same number of calories and the same exercise regime the chocolate bar eater still gains the most weight. It's not about healthy food vs unhealthy food either. It's what in the food that makes it healthy or unhealthy. The 100 calorie carrot is not a 100 calorie carrot it's actually 80 calories due the fact that humans cannot get to all the nutrients in vegetables simply because we cannot digest cellulose. The 100 calorie chocolate bar is not 100 calories it's 180 calories from all the fructose in the refined sugar and if you simply times that by 10 it's easy to see the difference. A calorie is not a calorie and don't be fooled. It's the same trick that is in diet foods and pop that actually is causing the issue of weight gain.

I mention this here because some people actually are trying to lose weight and if someone can't lose weight it's not in the genes or anything else but have been assured by society and scientists that a calorie is just a calorie, don't worry. I don't know about you but if someone told me not to worry, is when I start to worry.

As a general rule the body mass index is less reliable to athletes and the elderly. Athletes tend to have more lean muscle mass and less fat so the body mass index would over estimate the BMI as muscle weighs more than fat. The elderly have less muscle mass and more fat due to the consequences of natural aging. The older we get the more lean muscle mass we just tend to lose. So then the BMI would be underestimated.

The body mass index becomes then an index not on overall wellness but a indicator that disease will come at some point in the future. It's not good to be on either end; too skinny or too fat, but just right in the middle. It's an early warning sign; lose the fat and gain some lean muscle mass and it may stem off disease for another day.

As another note, fat has become so villainized and we as a society have become so fearful of fat that we want it all gone from our lives for good. The truth of the matter is that we need fat. Fat is actually good for us. At this point it's about getting good quality fat in our system rather than the junk fat. Fat is used to insulate us on very cold days, it runs as a secondary fuel system to keep our bodies going, it has evolved our brains to what it is today and fats are used in all our cells building and re-building cell walls.
