Height versus weight -
A good indicator of how much fat you carry is the body mass index BMI. Although it is not a perfect measure, it gives a fairly accurate assessment of how much of your body is composed of fat. Use the tool on this page to calculate your BMI. Having a BMI higher than Note that these are approximate values, and they are intended to be used only as a rough guide.
If you are worried about your BMI or are trying to lose weight, talk to your primary care doctor. You may also wish to contact the RUSH Center for Weight Loss and Lifestyle Medicine, which offers individualized weight loss and wellness programs for people of all ages.
You may also contact the RUSH Nutrition and Wellness Center or the RUSH University Prevention Center. These programs offer nutrition counseling and help with making lifestyle changes. Doctors at RUSH offer bariatric surgery for some people who are morbidly obese those with a BMI of at least 40, or a BMI of at least 35 plus an obesity-related disease such as diabetes or high blood pressure.

Home How Much Should I Weigh? A better measure was found to be the waist-to-height ratio. The medical establishment [50] and statistical community [51] have both highlighted the limitations of BMI. Part of the statistical limitations of the BMI scale is the result of Quetelet's original sampling methods.
For women, and people of non-European origin, the scale is often biased. As noted by sociologist Sabrina Strings, the BMI is largely inaccurate for black people especially, disproportionately labelling them as overweight even for healthy individuals. The exponent in the denominator of the formula for BMI is arbitrary.
The BMI depends upon weight and the square of height. Since mass increases to the third power of linear dimensions, taller individuals with exactly the same body shape and relative composition have a larger BMI. So, if all body dimensions double, and mass scales naturally with the cube of the height, then BMI doubles instead of remaining the same.
This results in taller people having a reported BMI that is uncharacteristically high, compared to their actual body fat levels.
In comparison, the Ponderal index is based on the natural scaling of mass with the third power of the height. However, many taller people are not just "scaled up" short people but tend to have narrower frames in proportion to their height.
tables are excellent for identifying obesity and body fat in large populations, but they are far less reliable for determining fatness in individuals.
For US adults, exponent estimates range from 1. In other words, people with small frames would be carrying more fat than optimal, but their BMI indicates that they are normal. Conversely, large framed or tall individuals may be quite healthy, with a fairly low body fat percentage , but be classified as overweight by BMI.
However, falling into one's ideal weight range for height and build is still not as accurate in determining health risk factors as waist-to-height ratio and actual body fat percentage. Accurate frame size calculators use several measurements wrist circumference, elbow width, neck circumference, and others to determine what category an individual falls into for a given height.
In this situation, BMI will increase without any corresponding increase in weight. Assumptions about the distribution between muscle mass and fat mass are inexact.
BMI generally overestimates adiposity on those with leaner body mass e. A study in June by Romero-Corral et al. In other words, the BMI will be mostly correct when determining a person to be obese, but can err quite frequently when determining a person not to be.
Despite this undercounting of obesity by BMI, BMI values in the intermediate BMI range of 20—30 were found to be associated with a wide range of body fat percentages.
Body composition for athletes is often better calculated using measures of body fat, as determined by such techniques as skinfold measurements or underwater weighing and the limitations of manual measurement have also led to new, alternative methods to measure obesity, such as the body volume indicator.
It is not clear where on the BMI scale the threshold for overweight and obese should be set. Because of this, the standards have varied over the past few decades. Between and the U. Dietary Guidelines have defined overweight at a variety of levels ranging from a BMI of In the National Institutes of Health NIH consensus conference recommended that overweight BMI be set at a BMI of In , an NIH report concluded that a BMI over 25 is overweight and a BMI over 30 is obese.
This became the definitive guide for determining if someone is overweight. One study found that the vast majority of people labelled 'overweight' and 'obese' according to current definitions do not in fact face any meaningful increased risk for early death.
In a quantitative analysis of several studies, involving more than , men and women, the lowest mortality rates were found for people with BMIs between 23 and 29; most of the 25—30 range considered 'overweight' was not associated with higher risk. The corpulence index uses an exponent of 3 rather than 2.
The corpulence index yields valid results even for very short and very tall people, [63] which is a problem with BMI.
For example, a In general, we do not err much when we assume that during development the squares of the weight at different ages are as the fifth powers of the height. This exponent of 2. The scaling factor of 1.
In Trefethen's analysis, an exponent of 2. BMI Prime is a dimensionless number independent of units. Individuals with BMI Prime less than 0. BMI Prime is useful clinically because it shows by what ratio e.
In South East Asian and South Chinese populations see § international variations , BMI Prime should be calculated using an upper limit BMI of 23 in the denominator instead of BMI Prime allows easy comparison between populations whose upper-limit optimal BMI values differ.
Waist circumference is a good indicator of visceral fat , which poses more health risks than fat elsewhere. According to the U. National Institutes of Health NIH , waist circumference in excess of 1, mm 40 in for men and mm 35 in for non-pregnant women is considered to imply a high risk for type 2 diabetes, dyslipidemia , hypertension , and cardiovascular disease CVD.
Waist circumference can be a better indicator of obesity-related disease risk than BMI. For example, this is the case in populations of Asian descent and older people. Waist-to-hip circumference ratio has also been used, but has been found to be no better than waist circumference alone, and more complicated to measure.
A related indicator is waist circumference divided by height. The values indicating increased risk are: greater than 0. The Surface-based Body Shape Index SBSI is far more rigorous and is based upon four key measurements: the body surface area BSA , vertical trunk circumference VTC , waist circumference WC and height H.
Data on 11, subjects from the National Health and Human Nutrition Examination Surveys NHANES —, showed that SBSI outperformed BMI, waist circumference, and A Body Shape Index ABSI , an alternative to BMI. Within some medical contexts, such as familial amyloid polyneuropathy , serum albumin is factored in to produce a modified body mass index mBMI.
The mBMI can be obtained by multiplying the BMI by serum albumin , in grams per litre. Contents move to sidebar hide. Article Talk. Read Edit View history. Tools Tools.
