Waist circumference and body fat -
Height and weight must be measured to calculate BMI. It is most accurate to measure height in meters and weight in kilograms.
However, the BMI formula has been adapted for height measured in inches and weight measured in pounds. For more, see About Adult BMI. Another way to estimate your potential disease risk is to measure your waist circumference.
Excessive abdominal fat may be serious because it places you at greater risk for developing obesity-related conditions, such as Type 2 Diabetes, high blood pressure, and coronary artery disease. Your waistline may be telling you that you have a higher risk of developing obesity-related conditions if you are 1 :.
Waist circumference can be used as a screening tool but is not diagnostic of the body fatness or health of an individual. Note : The information on these pages is intended for adult men and non-pregnant women only.
To assess the weight of children or teenagers, see the Child and Teen BMI Calculator. Preventing Weight Gain Choosing a lifestyle that includes good eating habits and daily physical activity can help you maintain a healthy weight and prevent weight gain.
The Possible Health Effects from Having Obesity Having obesity can increase your chances of developing certain diseases and health conditions.
Losing Weight Losing Weight If you are overweight or have obesity and have decided to lose weight, even modest weight loss can mean big health benefits. Underweight If you are concerned about being underweight, please seek a trained healthcare provider. The Academy of Nutrition and Dietetics Healthy Weight Gain webpage provides some information and advice on how to gain weight and remain healthy.

In our study, WC was the most predictive indicator of obesity for physical and functional limitations in women, which is consistent with the results of previous studies. Our results showed that loss of visceral fat and lean mass might be more important than BMI in determining obesity-related health risks in the elderly.
The mechanism by which obesity in older adults appears to protect muscle mass is unclear, and it is difficult to determine the exact cause and effect due to the complex interplay between obesity and sarcopenia.
Several hypotheses could explain this finding. First, skeletal muscle stimulation was increased as a higher level of muscle mass was observed in the obese group. Over time, there is less loss of muscle mass owing to the greater load required for exercise [ 27 ].
Second, because BMI is determined by height and weight, it cannot distinguish lean mass from body fat. Therefore, even non-sarcopenic elderly individuals with more muscle without fatty degeneration have a high BMI, so they have the disadvantage of being classified into the obesity group.
Therefore, it is possible that a high BMI in the elderly could not distinguish obesity from high muscle mass during body composition changes. In addition, a result showed a relatively poor correlation between PBF and BMI, and BMI correlated better with lean body mass than with fat mass, supporting this hypothesis.
A notable result from this study is that both WC and PBF, closely related to the amount of visceral fat in women, play a protective role in sarcopenia.
Increased leptin production by adipocytes contributes to ectopic fat deposition in the muscle, which reduces muscle quality and strength [ 43 , 44 , 45 ]. Adipose fat tissue from obese individuals has high levels of tumor necrosis factor-alpha TNF-α , which promotes the production and secretion of several pro-inflammatory cytokines.
These pro-inflammatory cytokines promote catabolic pathways that promote muscle wasting and ultimately impair muscle function restoration. In contrast to these metabolic pathways, Chen et al. reported that central obesity is associated with a lower risk of muscle mass loss in menopausal women, which is consistent with our findings [ 46 ].
Because abdominal fat stores high concentrations of sex hormones and positively affects skeletal muscle mass [ 43 , 47 ]. Adipose tissue, the main site for storing and metabolizing sex hormones, is the main source of estrogen.
Healthy adipocytes secrete adiponectin, an anti-inflammatory and insulin sensitizer that is positively associated with muscle cells [ 48 ]. This could explain the protective effect of sarcopenia in women compared to that in men, as found in studies of the interaction between adipocytes and muscle cells.
These findings are consistent with those of this longitudinal study as well as the cross-sectional study we previously reported. This study had several limitations. Second, in the survey conducted 2 years later, the follow-up loss was persons in this study, which was confirmed to be However, this was similar to or even lower than in previous cohort studies.
Third, this study might not apply to other populations because it was conducted in a single race, the Korean population. As body composition differs, studies on different populations are warranted.
This was the first longitudinal cohort study to investigate the association between obesity and the component parameters of sarcopenia in non-sarcopenic elderly individuals. Our study identified that Korean elderly with obesity had a protective impact on the reduction of muscle mass in men and women.
Obesity in older women may have a protective effect on reducing ASMI and the incidence of sarcopenia. Supporting data and data analysis materials are available from the corresponding author Prof. Yunsoo Soh upon request. Chapman IM. Obesity in old age. Obes Metab. Article Google Scholar.

BMI is a useful indicator of health at the population level. However, the distribution of fat on your body is more important that the amount, when assessing your disease risk.
For this reason, your waist circumference is thought to be a better predictor of health risk than your BMI. Increased abdominal obesity is related to a higher risk of cardiovascular disease, type 2 diabetes and cancer. Abdominal obesity is measured using waist circumference.
Body mass index BMI is an approximate measure of your best weight for health. It is calculated by dividing your weight in kilograms by your height in metres squared m 2.
BMI is intended for adults only, as children and adolescents are constantly growing. This makes it difficult to have set values for BMI cut-offs for young people.
However, in adults who have stopped growing, an increase in BMI is usually caused by an increase in body fat.
You can use the body mass index BMI calculator for adults to calculate your BMI, provided you know your:.
If your BMI is:. For older Australians over the age of 70 years, general health status may be more important than being mildly overweight. At the population level, BMI is used to indicate level of risk for morbidity disease risk and mortality death rates.
Differences in BMI between individual adults of the same age and sex are usually due to body fat, however there are many exceptions to this rule, which is why a BMI figure may not always be accurate. BMI calculations will overestimate the amount of body fat for:. However, BMI cannot differentiate between body fat and muscle mass.
This means there are some exceptions to the BMI guidelines:. BMI calculations used for adults are not a suitable measure of weight for children or adolescents. The current BMI charts for children have been developed by the US Centres for Disease Control and Prevention.
While the most accurate measures of body fat like are generally only Wist in medical and research Antioxidant rich legumes, there circukference some ways to measure body fat in the comfort of your own home. Body cirdumference levels vary depending on Wais factors, including Protein supplements for fitness, age, Waiwt body type. Still, body fat may be one important indicator of health, as having too much or too little is associated with a number of health issues 123. Skinfold calipers offer an inexpensive way to measure body fat. These handheld tools pinch and measure the thickness of subcutaneous under the skin fat in multiple areas of the body, including the abdomentriceps, and thigh. However, 8-site and 3-site measurements can also be used 456. After measurements are taken, the skinfold measurements are added. It is normal for Antioxidant supplement benefits body amd store energy fa fat. However, too much or too little Protein supplements for fitness fat can increase your circumfernece of illness and circkmference, depending on boy your body stores it. The amount of fat your body has stored can be accurately measured with a dual-energy absorptiometry or DXA machine. This is known as having a DXA scan. A much cheaper alternative is to estimate your total amount of body fat by calculating your body mass index BMI. BMI is a useful indicator of health at the population level.
