The Body Mass Index (BMI) value of an individual is a number that is calculated using their weight and height.
Although BMI does not measure body fat directly, research has shown that an individual's BMI level correlates to direct measures of body fat. In many cases, the Body Mass Index approach can be considered a viable alternative to direct measurements of body fat. For example, a person may have a high BMI, but in order to determine if the excess weight represents a health risk, a medical professional would need to perform additional tests. Within the metric system, the formula for BMI is [weight in kilograms] divided by [height in meters squared].
Within the American Standard system, calculate BMI by dividing [weight in pounds (lbs)] by [height in inches (in) squared] and multiplying by a conversion factor of 703. Once an individual has calculated their BMI value, they can reference Table #1, below, to determine whether their BMI value is within the ideal weight range.
Note: Table #1 and Table #2 are to be used only by male and female adults 20 years of age and older.
The correlation between the BMI number and an individual's level of body fat is fairly strong.
At the same BMI level, older individuals tend to have a higher level of body fat than younger adults.
Athletes may have a high BMI value due to their elevated level of lean muscle mass, which weighs more than fat. It's also important to remember that an individual's BMI value is only one factor related to risk for disease. The individual's waist circumference (abdominal fat is a predictor of an individual's risk level for obesity-related diseases).
Although the BMI value is calculated the same way for children, adolescents and adults, the criteria used to interpret the results of the BMI value for children and adolescents are different from those used for adults.
The Centers for Disease Control and Prevention (CDC) have compiled BMI charts that take into account these differences and facilitate the translation of the BMI value into a percentile. After the BMI value has been calculated for a child or an adolescent, the BMI value is plotted on the CDC BMI age growth chart (for either girls or boys) to obtain a percentile ranking. Table #3 represents the CDC BMI weight status categories and the corresponding percentiles used for both children and adolescents. BMI values are used as screening tools to identify potential weight concerns for children and adolescents. The standard BMI formulas used earlier in this article for adults can be used for children and adolescents of both sexes. To determine the appropriate weight range for a given child or adolescent, Table #4 or #5 will need to be used in conjunction with Table #3. The BMI method of determining an individual's optimum weight has proven to be fairly reliable and accurate throughout the years. It is recommended that each individual determine their optimum weight via the alternative methods provided within this section of our website. Rushing, making do and eating on the go all lead to unhealthier eating habits like snacking, eating fast food, TV meals, fussy eating and so on.
Body Mass Index (BMI) is a person's weight in kilograms divided by the square of height in meters. After BMI is calculated for children and teens, it is expressed as a percentile which can be obtained from either a graph or a percentile calculator (see links below).
The BMI-for-age percentile growth charts are the most commonly used indicator to measure the size and growth patterns of children and teens in the United States. The following is an example of how sample BMI numbers would be interpreted for a 10-year-old boy. For children and teens, BMI is not a diagnostic tool and is used to screen for potential weight and health-related issues.
BMI is interpreted differently for children and teens even though it is calculated as weight A· height2. Obesity is defined as a BMI at or above the 95th percentile for children and teens of the same age and sex.
For adults, BMI is interpreted as weight status categories that are not dependent on sex or age.
Normal or healthy weight weight status is based on BMI between the 5th and 85th percentile on the CDC growth chart.
The prevalence of children and teens who measure in the 95th percentile or greater on the CDC growth charts has greatly increased over the past 40 years. CDC and the American Academy of Pediatrics (AAP) recommend the use of BMI to screen for overweight and obesity in children and teens age 2 through 19 years.

My two children have the same BMI values, but one is considered obese and the other is not. See the following graphic for an example for a 10-year-old boy and a 15-year-old boy who both have a BMI-for-age of 23.

This is an important measure because it signals whether you have an unhealthy amount of fat stored around your abdomen. Waist circumference is good to use in conjunction with BMI as BMI does not indicate where you are storing your excess weight or if the weight is from muscle or fat. The measurement guidelines have only been developed for adults and can therefore not be applied to children. Locate the spot halfway between your lowest rib and the top of your hip bone (this will be approximately where your belly button is, or close to it). The table below illustrates the available ‘at risk’ ranges for waist circumference, based on different ethnic groups. It is important to keep in mind that your BMI could indicate that you are a healthy weight but on the other hand, your waist circumference may reflect an increased risk for chronic disease.

Be sure to give yourself some cheat days from time to time so that you do not start to feel overwhelmed.
It is still possible for people with allergies or exercise induced asthma to workout, even though these conditions may cause breathing problems. If you are not a morning person, but want to workout before work, try getting up about 15 minutes earlier than you generally do to fit a small routine in. When you are working out on a regular basis, it is important to add in the element of stretching to your plan. Exercise can be the eight-letter word that some people just hate.  To some, it means hurting muscles, sweating and extreme will power.
The BMI value for an individual can be a useful tool in determining whether the individual is underweight, overweight, or within the medically approved weight range for their height. The BMI approach to determining your optimum weight is similar to underwater weighing and dual energy x-ray absorptiometry (DXA). Calculating one’s BMI level is inexpensive, easy to perform, and a quick way to determine whether an individual’s weight is appropriate for their height. Under this scenario, the medical professional may suggest performing a skinfold caliper test and reviewing the individual's diet, level of physical activity, family history, and possibly a whole host of additional health screenings.
Since height is commonly measured in centimeters, divide the height (in centimeters) by 100 to obtain height in meters. Table #2 can be used to determine an individual's BMI value without performing any mathematical computations. For children and adolescents, BMI value is not only age-specific, but sex-specific as well.
Percentiles are the most commonly used indicators to assess the size and growth patterns of individual children in the United States. The CDC and the American Academy of Pediatrics (AAP) recommend the use of the BMI approach to screen for overweight and obesity in children beginning at 2 years of age. Once the BMI value has been calculated for a child or an adolescent, the value can then be applied to either Table #4 or Table #5, depending on whether the child or adolescent is a male or a female. For example, for a boy that is 10 years of age and has a BMI value of 23, using Table #4 shows that the individual is above the 95th percentile. It is now necessary to reference Table #3 and choose the weight category that applies to the equal to or greater than the 95th percentile. As stated earlier in this article, there are a few instances in which the BMI method fails to accurately depict the optimum weight for an individual (e.g.
Once the optimum weight levels have been determined using the alternative methods, it is recommended that you compare the results to evaluate the similarities and differences.
BMI does not measure body fat directly, but research has shown that BMI is correlated with more direct measures of body fat, such as skinfold thickness measurements, bioelectrical impedance, densitometry (underwater weighing), dual energy x-ray absorptiometry (DXA) and other methods1,2,3. BMI-for-age weight status categories and the corresponding percentiles were based on expert committee recommendations and are shown in the following table.
For example, a child may have a high BMI for their age and sex, but to determine if excess fat is a problem, a health care provider would need to perform further assessments. Because there are changes in weight and height with age, as well as their relation to body fatness, BMI levels among children and teens need to be expressed relative to other children of the same sex and age. It is difficult to provide healthy weight ranges for children and teens because the interpretation of BMI depends on weight, height, age, and sex. It is not appropriate to use the BMI categories for adults to interpret the BMI of children and teens. So if the children are not the same age and the same sex, the interpretation of BMI has different meanings.

How about being at work with nothing to eat except that Burger King or Taco Bell down the road.  Delicious, we know!  But not the healthiest options. Steel cut oatmeal, Eggs, Greek Yogurt with fruit and nuts.  If you do not fuel your body correctly in the morning, you will be burning muscle rather than fat in the gym. Because so many different structures make up the shoulder, it is vulnerable to many different issues.
The risk of these conditions developing can be significantly reduced through healthy diet and exercise. The abdomen is the most dangerous place to store fat as it surrounds many vital organs like the heart, kidneys, liver and pancreas.
There is less risk associated with fat stored around the hips and thighs (pear shape), opposed to the abdomen. A figure that exceeds the above ranges indicates the presence of intra-abdominal fat stores (visceral fat) that will be coating your organs! This can occur if you store most of your fat around your abdomen and if you have minimal muscle.
It won’t tell you if you are within a healthy range but it can indicate if you have been gaining or losing weight.
They can measure a child’s length, weight and BMI from birth to 2 years of age and from 2 years of age to 18 years. She is constantly ensuring her knowledge is up to date by attending conferences, workshops and keeping on top of newly emerging evidence.

Whether you already have a fitness routine of your own or you have just made the decision to get fit, some advice might help you get more out of your fitness efforts.
This is equally true for both your diet and your exercise routine as your body needs recovery days and every once in awhile you need to give in to your cravings. Consult with your doctor about taking any medications you need before exercising.  Before beginning your exercise routine, jog in place for 15 minutes or take a short walk. This is plenty of time to do some light exercise before work.  You can even do something as simple as walking. Stretching allows your muscle fibers and limbs to stretch so that muscles can recover and perform even better the next time you workout.  Add stretching in for a variety of benefits in your fitness program. Remember that achieving a goal is, above all, an opportunity to set a new goal.  Fitness is, overall, a goal for life, not for a brief time.
You should not be afraid to adjust your own fitness efforts in order to develop a routine that works for you. A healthy diet is a crucial part of an overall healthy, balanced lifestyle, and over the past few years, there has been a serious shift toward focusing on internal health, rather than dieting to try to lose weight or achieve a certain look.
Furthermore, the Body Mass Index technique is used as a screening tool to identify possible weight concerns for adults.
Table #1 represents a BMI scale that is specifically designed for adult men and women only.
The Y-axis represents the height of an individual, and the X-axis depicts an individual's weight. The first step is to identify your height on the Y-axis.


However, for children and adolescents, the interpretation of their BMI values are both age and sex-specific.
The percentile value represents the position of the child's BMI value relative to children of the same sex and age. For children and adolescents, the BMI approach can be used to screen for obese, overweight, healthy weight or underweight conditions.
Table #4 is designed to be used for a male child or adolescent, while Table #5 is designed to be used for a female child or adolescent. These assessments might include skinfold thickness measurements, evaluations of diet, physical activity, family history, and other appropriate health screenings.
These percentiles are calculated from the CDC growth charts, which were based on national survey data collected from 1963-65 to 1988-944. This would place the boy in the 95th percentile for BMI, and he would be considered to have obesity.
Although BMI is used to screen for overweight and obesity in children and teens, BMI is not a diagnostic tool. For children of different age and sex, the same BMI could represent different BMI percentiles and possibly different weight status categories. A comparison of the Slaughter skinfold-thickness equations and BMI in predicting body fatness and cardiovascular disease risk factor levels in children.
Body fat throughout childhood in 2647 healthy Danish children: agreement of BMI, waist circumference, skinfolds with dual X-ray absorptiometry. It increases the risk of diseases like type two diabetes, heart disease, some cancers and hypertension [2].
However, it is believed that waist measurements may be higher for Pacific islanders and African Americans than Caucasians and lower for Asian men [3].
One downfall is that it cannot differentiate between weight contribution from muscle and weight contribution from fat.
Pay attention to whether your clothing has become tight or loose – you may need to take a look at how your diet has changed to encourage the altered weight. These measurements are plotted on percentile charts that compare a child’s growth and development in relation to other children of the same age and gender. It is important to note that the ranges are not tailored to each individual and therefore may not be accurate for everyone – in this case, interpretation by a health professional may be useful. Passionate about health and wellbeing, we write about issues relevant to our clinical practice. Instead, just physically move more than you do already.  If that means dancing while you are stirring a pot of beans, then do that.
After climbing to a peak that has been focused on, selecting the next, higher peak to tackle will keep a regimen aimed towards life-long fitness.
Ideas like those above can help you build a fitness routine that gives you maximum results with minimum effort. However, it is important to do your research and familiarize with research from different nutritionists, doctors, and health experts. Children and adolescents will utilize an alternative scale, discussed later in this article. Thereafter, simply move to the right until you are under your specific weight. The intersection of your height and your weight will represent your BMI value. However, as long as the conditions applicable to creating the inaccuracies in the BMI results are not present, this method will prove to be a reasonable benchmark for determining an individual's optimum weight level. In general, BMI is an inexpensive and easy-to-perform method of screening for weight categories that may lead to health problems. Because weight and height change during growth and development, as does their relation to body fatness, a childa€™s BMI must be interpreted relative to other children of the same sex and age. The American Academy of Pediatrics recommends the use of BMI to screen for overweight and obesity in children beginning at 2 years old. This means that the childa€™s BMI is greater than the BMI of 95% of 10-year-old boys in the reference population.
To determine whether the child has excess fat, further assessment by a trained health professional would be needed.
The waist circumference measurement therefore indicates an individual’s risk of developing chronic disease. Breathe out normally and take the measure – it is helpful if someone can take the measure for you. Limited data indicates that the risk for Aboriginal populations is similar to that of Asian populations and the risk factors in Torres Strait Islander populations similar to Pacific Islanders [3]. From this, you can readjust your diet to manage your weight, instead of purchasing new clothing! For example, a child that is on the 80th percentile for height and weight is heavier and taller than 80% of other children. By relying on information that you were taught as a child, or by only following the instruction of one doctor, you might be missing out on valuable information. For instance, a child or adolescent may have a high BMI value for their age and sex, but to determine if excess fat is a problem, a medical professional will need to perform additional tests.
The results can be interpreted by a health professional like a dietitian or medical doctor. These tests typically include skinfold thickness measurements, evaluations of diet, physical activity and family history, and any other appropriate health screenings. Yogurt, milk, juice, breakfast cereal, and other products that are advertised as having extra added Omega 3s, Vitamin C, Calcium, or antioxidants are popular choices among people who want to eat only healthy foods and meals.
For example, drinking orange juice that has extra added calcium might seem like a great way to achieve your recommended calcium intake; however the calcium that is added to orange juice isn’t always the type or strength you need, and orange juice does not make it easy for your body to absorb. Most vitamins and minerals have specific foods or other nutrients that need to be taken with them in order for optimum absorption, so throwing added nutrients into everything usually isn’t very effective. It’s just messing with nature.Natural Food for Better HealthIf you really want to eat healthy foods and meals, your best bet is to eat natural, unprocessed food. If vitamins and minerals are what you seek, it’s best to get them from their natural sources, rather than as supplements tacked on to other processed foods.
Vitamins and minerals in their natural forms (in the foods they naturally occur in) are made to be easier to absorb, so they will be more effective and have a better and more positive impact o your body and overall health.
Take some time to learn about what combinations of foods are the most powerful and will benefit your body the most, and plan your meals accordingly. There aren’t heavy legal restrictions on what can be classified as organic, and many brands will use the organic label simply to sell their products, even if they don’t quite fit the organic description. You should always do a little research on the brands you are interested in buying to decide if they really are free of chemical pesticides, genetic modification, and other potentially harmful procedures. You might also want to look at the organic regulations in your area to determine just how easy it is for companies to earn that designation for their products.If you aren’t certain that the produce you are buying actually lives up to its organic title, there is a simple solution to ensure that you are getting the wholesome, organic food that you need: grow it yourself! If you have space for a garden, you should take advantage of it and try growing your own vegetables. You’ll know where they came from and will feel more comfortable eating them, and will be saving money and trips to the grocery store as well.Eating healthy foods and meals is a noble goal, but if you are not careful, you can easily be fooled into eating things that aren’t the best for your health.
