Is Weight Just a Number? What Experts Say Really Matters When It Comes to Health

16 min read

Between celebrities shilling urge for food suppressants and reality exhibits extolling excessive weight loss at any value, it might appear to be seeing the correct number on the size is the golden ticket to complete health and happiness. But current cultural debate and a growing body of analysis means that measuring your weight is just one piece of the wellness puzzle.

Numerous studies in the previous few years have challenged long-held beliefs that bodyweight is an absolute measure of general health. A 2014 systematic evaluate of varied research included the finding that a good portion of people categorized as overweight are metabolically healthy (with no indicators of insulin resistance or elevated blood strain or ldl cholesterol). A 2016 research discovered that “people with healthy obesity have lower risks for diabetes, CHD [coronary heart disease], stroke, and mortality” than unhealthy subjects who will not be overweight. With so much conflicting info, it’s no marvel you may be confused.

“I find that people tend to obsess about the number on the scale,” says Boston-based household drugs physician, Michael Richardson, MD., “but it may not be a true representation of their health (especially for athletes), and a lack of weight loss progress can be incredibly demotivating and derail individuals trying actively to improve their health.”

Instead, specialists agree it’s the patterns or tendencies you’ll be able to see in your weight extra time and the healthy habits you tackle that matter most.

Why Weight and BMI Don’t Equate Exactly to Health

It’s essential to understand that when individuals casually speak about “weight” and its association to health, they could possibly be speaking about a number of issues—fairly often, it’s the precise quantity on the size (weight) or the physique mass index (BMI), a person’s weight in kilograms divided by the square of their height in meters. While BMI is usually used to assess weight categories (“underweight,” “normal/healthy,” “overweight,” and “obese”) that could possibly be associated with certain health circumstances, the Centers for Disease Control (CDC) points out that it’s “not diagnostic of the body fatness or health of an individual.” While the ideas of weight and BMI are associated, Richardson says they have very totally different meanings and implications for health.

“If we emphasize weight and BMI, we are missing out on all the other aspects that impact health, such as physical activity, the quality of food eaten, and more,” he says. “BMI and weight can be useful tools for assessing a person’s size, but health is better measured by improvement and maintenance of healthy behaviors.”

One huge drawback with using only weight or BMI to outline health is the danger of “weight bias” or “weight stigma”—a.okay.a. “negative attitudes towards, and beliefs about, others because of their weight…manifested by stereotypes and/or prejudice towards people with overweight and obesity,” in accordance to the WHO. “Weight stigma has a negative impact on one’s mental health and can lead to the avoidance of health care, potentially causing people—especially women—to miss out on preventative screenings and early health-condition interventions,” says Natalie Jovanovski, a postdoctoral researcher at Australia’s Swinburne University. And when individuals fall outdoors of the accepted weight norms, the “failure” to measure up can gasoline physique dissatisfaction and lead to compulsive dieting, exercising, and physique monitoring, she says.

Internalizing the message that weight loss ought to be the last word aim of all healthy behaviors can lead to partaking in typically-beneficial behaviors, like understanding, for all the incorrect causes, says Jovanovski. “Research suggests that solely specializing in exercise to change one’s body form, weight, or measurement, or obsessively monitoring one’s behaviors, is detrimental to health and wellbeing, and doesn’t recognize our innate want to transfer and take part in bodily exercise for the needs of enjoyment and social connection,” she says.

Making Sense of Mixed Science  

While many health specialists still depend on BMI to shortly verify a person’s weight status, many admit the software isn’t perfect because it doesn’t inform the entire story. So why do docs and different health specialists still use it?

“Doctors use BMI to quickly assess if someone is overweight or obese, but we also recognize this measure is imperfect and does not necessarily describe how fat is distributed in the body, how fat is utilized, or the overall calorie imbalance in a person’s diet,” says Richardson. “Some research have discovered that metabolically healthy overweight individuals (being overweight but with normal cholesterol levels, blood sugar, and blood strain) have a minimal elevated danger of coronary heart disease, and in some situations, have a lowered danger of demise in contrast to normal weight individuals.”

Richardson says that is what specialists call ‘The Obesity Paradox.’ But, to confuse issues more, some studies have found robust proof that immediately opposes the Obesity Paradox, like a current paper revealed in JAMA Cardiology. “It showed overweight and obese people were not only at higher risk of cardiac death, but had fewer ‘healthy life years’ when compared to normal weight people,” explains Richardson.  

“The data clearly shows that obesity is associated with heart disease, diabetes, and early death, but the cause of these poor health outcomes may be due to the behaviors that lead to obesity, not a person’s size,” says Richardson. “Lack of exercise, overeating, and other negative behaviors can significantly harm our health due to their effect on blood pressure, cholesterol, body fat, and blood sugar. By solely looking at BMI, a calculation based on height and weight, we are not capturing a person’s whole health, their different risk factors, or the impact these risks have on the body.”

Fitbit’s in-house dietitian Tracy Morris agrees that the simplicity and accessibility of BMI makes it an interesting device, however she doesn’t dwell on it. “Measuring someone’s weight and height are very quick and easy, and you can use those numbers to get an initial idea of whether or not they are carrying a healthy weight for their frame,” she says. “But a person’s BMI doesn’t paint the complete image of their health. It tells us nothing about their physique composition—is that additional weight principally unhealthy fats or principally metabolically-active muscle? To determine this out, I’d get my shoppers to bounce on a Fitbit Aria 2 scale. And where is the additional weight being carried? We know if it’s across the belly, it puts you at a larger danger of disease. A waist circumference measurement may also help suss that out.”

Other Health Measurements to Consider

Because weight and BMI don’t take the social determinants of health under consideration, “such as whether somebody’s health is impacted by poverty, disability, stigma and discrimination, or other important factors,” Jovanovski believes a more accurate definition of “health” and general wellness would embody a mixture of bodily, psychological, and sociological measures. “These factors cannot be viewed separately,” she says.

According to Richardson, the important thing to higher health isn’t in deprivation, however in fostering constructive behaviors in every side of life. “I recommend focusing on increasing healthy behaviors,” he says. “If a person is able to quit smoking, eat fewer processed foods, and incorporate more activity in their daily life, I’m not very worried if the number on the scale doesn’t shift. I know they are improving their health in the long term, and weight changes will come over time.”

Getting started on a more healthy path and making healthy habits stick doesn’t have to be difficult. “Strapping on a Fitbit device and tracking your daily activity is a great place to begin,” says Morris. “From there it’s all about taking small steps towards your goals—swap out candy for fruit, soft drinks for water, and make choices that help you to be more active, like parking in the farthest spot, and inviting your girlfriends to a dance class instead of a boozy happy hour.”

When healthy habits develop into a way of life, the quantity on the size can go back to being exactly what it is—one little metric about your body, not some crazy quantity that defines your health or who you’re.
