A waistline measurement is a better indication of fat distribution. BMI doesn't provide an accurate measure of fat versus muscle mass.
In healthy men waist circumference correlated more strongly with physical fitness (as calculated by a maximal fitness test) than the BMI, whereas in healthy women BMI correlated somewhat more strongly with physical fitness than waist circumference.
The researchers stressed that waist circumference was a more important marker than overall obesity and advised doctors to measure their patient's waists to identify those at risk.
Measuring waist circumference helps screen for possible health risks that come with overweight and obesity. If most of your fat is around your waist rather than at your hips, you're at a higher risk for heart disease and type 2 diabetes.
Scientists say waist-to-hip ratio better measure for healthy weight than BMI.
That's a problem, because fat tissue weighs less than muscle tissue. So a an out-of-shape guy with a high amount of body fat could end up having a lower BMI than a really fit guy who's the same height, but has a lot more muscle tissue.
What should your waist measurement be? For men, a waist circumference below 94cm (37in) is 'low risk', 94–102cm (37-40in) is 'high risk' and more than 102cm (40in) is 'very high'. For women, below 80cm (31.5in) is low risk, 80–88cm (31.5-34.6in) is high risk and more than 88cm (34.6in) is very high.
The average waist circumference for women aged 18 and over in 2017–18 was 88 cm (ABS 2018). A high-risk waist circumference is more common in older women. In 2017–18 (ABS 2019): around 4 in 5 women aged 75 and over (84%) had a high risk waist circumference.
Now that you've measured your waist circumference you need to know what it means. To have your best chance at maintaining good health, you should aim for: Men should have a waist circumference of 40 inches or less. Women should have a waist circumference of 35 inches or less.
Body mass index (BMI) has been reported to be related to the risk of type 2 diabetes and hypertension. However, waist circumference or waist-to-hip ratio (WHR) can better reflect the accumulation of intra-abdominal fat and might be a better predictor than BMI of the risk of type 2 diabetes and hypertension.
When you start to lose fat, it's proportionate throughout your body, whether it's your neck, waist, ankle circumference. You'll come out smaller but have the same body shape."
A healthy BMI for an adult is between 20 and 25. For older Australians over the age of 74 years, your general health may be more important than being mildly overweight. Some researchers have suggested that a BMI range of 22-26 is acceptable for older Australians.
BMI (body mass index), which is based on the height and weight of a person, is an inaccurate measure of body fat content and does not take into account muscle mass, bone density, overall body composition, and racial and sex differences, say researchers from the Perelman School of Medicine, University of Pennsylvania.
Because BMI does not measure body fat directly, it should not be used as a diagnostic tool. Instead, BMI should be used as a measure to track weight status in populations and as a screening tool to identify potential weight problems in individuals.
Likewise, models can be older but agencies and clients tend to like their models looking younger and more youthful. Height is typically between 5'9″-6″, bust is between 32″-36″, waist is between 22″-26″, and hips should be between 33″-35″.
For your best health, your waist should be less than 40 inches around for men, and less than 35 inches for women, although it may vary depending on race or ethnicity. If it's larger than that, you may want to talk with your doctor about what your next steps are, including losing weight.
How quickly will you lose weight? The volunteers reduced their waist sizes by an average of 1 inch for every 4lb (1.81kg) they lost. So if you lose 1lb (0.45kg) a week you could hope to reduce your waistline by an inch after four weeks.
The phrase 'skinny fat' or metabolically obese normal weight (MONW) is used to describe someone who appears to be lean, but actually has a high body fat percentage. If they were to calculate their body mass index (BMI) or even weigh themselves, they may appear to be healthy, but this can be deceiving.
Muscle is denser than fat, and as it is more compact within your body, as you gain muscle mass, you end up looking thinner, no matter your physical weight. So, if you've been doing a lot of strength training lately, it's likely this is the reason that you're looking fantastic but not dropping those numbers.
under 18.5kg/m2 – you are considered underweight and possibly malnourished. 18.5 to 24.9kg/m2 – you are within a healthy weight range for young and middle-aged adults. 25.0 to 29.9kg/m2 – you are considered overweight.
