Is not always easy Better. Never been more true than Body Mass Index, Or BMI.

A measure that takes into account one’s height and weight, the body mass index has been used since 1800 by anatomy and estimation, as an easy way to expand, health. After all, coming on a scale and tape measure is not very difficult. To calculate your BMI, that’s all you need.

BMI has been strongly linked to America’s most common diseases, conditions and causes of death, heart disease, type 2 diabetes, and even cancer. This means, as BMI increases, so is your risk of serious disease. For example, an adult male who weighs 5 feet, 10 inches, and 170 pounds has a BMI of 24.4, which is considered healthy. (A BMI of 25 is considered overweight.) The same BMI number will apply to a woman who is 5 feet, 4 inches tall and weighs 142 pounds.

A BMI of 40 or more is associated with a significantly younger age, with a BMI of 55 to 59.9 compared to the average person living 13.7 fewer years than an average person with a normal BMI of 18.5 to 24.9, according to a 2014 review Published in PLOS ONE.

“When studying large populations, we need an easy way to reach Body composition, “telling Dr. Lisa Neff, a Endocrinologist Who specializes in diabetes and metabolism Northwestern Memorial Hospital in Chicago. “That’s why BMI is the most frequently used marker in health outcomes research. However, when we’re studying BMI, we’re really looking forward to assessing body fat. It’s the body. The primary detrimental aspect of composition is. When we talk. Risk, it’s body fat, or excess body fat, with which we’re really concerned. “

but unfortunately, BMI and body fat Whatever it is but the same thing. BMI is all about quantity and looks at body fat quality. For example, if you have a high BMI, you can either be overweight (aka overfoot) or on the flip side, you may actually just be muscular and have a perfectly healthy body or very little body. Body fat percentage may occur, explains San Diego bariatric surgeon Dr. Julie Elner. And, in fact, research published in the 2016 International Journal of Obesity suggests that B.M.I. Incorrectly labeled More than 54 million Americans are “unwell”. It accounts for about half of all overweight men and women – and 29 and 16 percent of those people are obese or severely obese, respectively.

Meanwhile, if you have a normal BMI, you can be healthy – or you can quietly suffer from normal weight obesity, often referred to as “slim fat”. Obesity, weight, and BMI are well tested with normal weight, but the higher the body fat levels, the more they are generally considered obese. The same 2016 study found that more than 30 percent of people with so-called “healthy” BMI have poor cardiometabolic health – including high blood pressure, high cholesterol, excess inflammation and / or insulin resistance. This is exactly what helps to identify BMI, and your doctor probably has a BMI chart hanging in the exam room.

While athletes, bodybuilders, and those who regularly reinforce vehicles are at risk of being misled as overweight or obese, BMI is more likely to be missed in normal weight obesity in women as well as in older people. Those who may suffer from age-related muscles known as sarcopenia, according to Neff. In many such older individuals, the weight may actually be quite stable, she notes. In many men and women, as the level of muscle increases, the metabolic rate decreases and any possible weight loss leads to an increase in fat. Year after year, weight remains about the same, although body fat percentage increases gradually, increasing the risk of obesity-related diseases.

Better than BMI: body fat, waist circumference and waist to hip ratio

Since BMI is actually only an estimate of body fat, it makes the most sense to stop tracking your BMI and start evaluating your body fat percentage, Ellen says.

“My advice to patients is to get a good body composition scale for home use,” she says. “It will calculate body fat percentages and give credit to patients who work outdoors and are above-average healthy, while applying those who are at ‘good weight’ but unwell to the extent that they need to keep their schedule.” Need to change. “

These scales are not 100 percent accurate – technology still has a way to go before consumer scales are accurate with expensive dual-energy X-ray absorptiometry (DXA) scans, underwater weights, and caliper skin-fold measurements Determine body fat levels, but they are as accurate as anyone dying for good health or healthy weight loss needs. While no one is mutually agreed on the extent of healthy body fat, body fat percentage is higher than about 21 in men and 31 in women. Men and women, respectively, are required to maintain at least 3 and 12 percent of body fat levels. Optimal physical functioning.

whereas waist perimeter And the ratio of waist to hip, like BMI, indirectly estimates body fat, they focus Where on Store the fat you have. that’s because visceral fat, Which is located in and around vital organs, is more correlated with chronic disease than the accumulation of fat elsewhere in the body, Elenar explains. “Abdominal obesity” is strongly associated with increased risk of heart disease, Regardless of BMI, According to the Journal of Cardiovascular Disease Research.

To track your waist circumference, wrap a flexible measurement tape or string around your waist, marked by the top of your hipbone. Divide that number by the circumference of your hips at their greatest point, and you’ll have your waist-to-hip ratio.
