Our reference chart shows if you are of average BMI and weight, overweight, or considered obese for your height. Includes world obesity statistics listed by major countries table.
Obesity is a condition characterized by the build up of excessive body fat. Obesity is defined differently depending on the country, but in Western countries, such as the U.S. and many European countries, obesity is defined as a body mass index (BMI) of 30 kg/m^2.
Weight that is higher than what is considered as a healthy weight for a given height is described as overweight or obese. Body Mass Index, or BMI, is used as a screening tool for overweight or obesity. Generally, you are not considered obese until your body weight is at least 20% above what it should be.
The most common way to determine whether or not you are of average healthy weight is by calculating your body mass index, or BMI. If your BMI is between 18 - 25 you are a normal weight. If your BMI ranges between 25 - 30 you are overweight. If your BMI is over 30 you are considered obese. Our chart below shows the data already calculated for you. Or, if you prefer, we have an Adult BMI Calculator and Chart, as well as a BMI Calculator for Children.
Body mass index (BMI) is the most widely used measure to diagnose obesity. However, the diagnostic accuracy of BMI to detect excess in body adiposity (obesity) is largely unknown. The main issue for using BMI is that regardless of gender and age, the same criteria is used to determine whether one is normal, overweight or obese. However, BMI should be used carefully when determining whether one is obese or not, especially when classifying different categories of people.
BMI does not really accurately tell how much fat a person really has; this is due to the nature that it cannot really differentiate between body fat and muscle mass. This is especially true when BMI were used to measure athletes, a large percentage of them were often considered to be obese, where in actual fact they are not. Many athletes tend to have high BMI due to muscle mass being built up and not due to body fat.
The United States CDC states;
"BMI does not measure body fat directly, but research has shown that BMI is moderately correlated with more direct measures of body fat obtained from skinfold thickness measurements, bioelectrical impedance, underwater weighing, dual energy x-ray absorptiometry (DXA) and other methods. Furthermore, BMI appears to be strongly correlated with various adverse health outcomes consistent with these more direct measures of body fatness." - (www.cdc.gov/obesity/adult/defining.html)

Today the United States ranks as the most obese country in the world. In the average country tracked by the OECD, about 1/5 of the population is obese.

Many Americans are in denial about the numbers on the scale, with only half of those who are overweight or obese reporting as such. Which may help explain why a recent Gallup poll found that the obesity rates among American adults is still on the rise! If Americans keep getting heavier at the current rate, 42% of the population will be obese by 2030, a new study says. The increase accounts for an additional 32 million obese Americans and a whopping $549.5 billion in medical expenditures over the same time frame. The data did not include child obesity, so the estimates could be conservative. Obese children typically become obese adults, says America's Centers for Disease Control and Prevention's (CDC), who has proclaimed American obesity to be an "epidemic". The study is published online by the American Journal of Preventive Medicine.
In June 1998 the American National Institutes of Health (NIH) announced its BMI guidelines, to determine healthy weight, to ensure researchers, dietitians, doctors and government agencies were using the same BMI data classifications.
|BMI Number||Classified As:|
|Less than 18.5||Underweight|
|18.5 to 24.9||Normal|
|25.0 to 29.9||Overweight|
|30.0 to 34.9||Obesity - Class I|
|35.0 to 39.9||Obesity - Class II|
|More than 40.0||Extreme Obesity - Class III|
Current classifications of obesity based on body mass index, waist circumference and other anthropometric measures, although useful for population studies, have important limitations when applied to individuals in clinical practice. Thus, these measures do not provide information on presence or extent of comorbidities or functional limitations that would guide decision making in individuals - (https://www.ncbi.nlm.nih.gov/pubmed/19188927).
The Edmonton obesity staging system (EOSS), is a 5-point ordinal classification system that considers comorbidity and functional status, in predicting mortality in a nationally representative US sample. The Edmonton obesity staging system independently predicted increased mortality even after adjustment for contemporary methods of classifying adiposity. The Edmonton obesity staging system may offer improved clinical utility in assessing obesity-related risk and prioritizing treatment - (http://www.cmaj.ca/content/183/14/E1059).
|Edmonton Obesity Staging System Chart|
|Stage 0||Person has no obesity-related risks (normal blood pressure, glucose levels) or symptoms, psychopathy or limitations.|
|Stage 1||Subclinical risk factors related to obesity are present. A person may have borderline hypertension. There may be mild physical symptoms (aches/pains), psychopathy and limitations.|
|Stage 2||The person has obesity-related chronic diseases and moderate symptoms and limitations.|
|Stage 3||The person has damaged organs and experiences significant limitations.|
|Stage 4||The person has severe disabilities as a result of obesity-related chronic disease(s).|
Generally, obesity is treated with certain lifestyle changes such as diet plans and making exercise routines. Medications and surgeries may also be an option depending on the cause of the obesity, its severity, and the individual's choices. If you have been diagnosed with obesity, contact your doctor to discuss the most current treatment options.
