BMI (Body Mass Index) is a measurement of the body’s overall weight. It is a useful tool for determining whether or not someone is overweight or obese. BMI uses your height and weight to measure the appropriate body weight for each person. It is a reliable indicator to identify the risk of diseases associated with excess body fat. Some of the diseases linked with a high BMI include respiratory issues, gallstones, type 2 diabetes, high blood pressure, and heart disease.
BMI is a simple and inexpensive approach to determine your estimated level of body fat. You may use a number to determine if you’re at a healthy weight for your height and gender. The greater the number, the more body fat a person has in general. BMI is frequently used to determine whether your weight puts you at risk for health issues, including cancer, diabetes, and heart disease.
The BMI provides a decent estimate of total body fat for most people, but it does not work for everyone. Bodybuilders and other muscular persons, for example, may have a high BMI due to their muscle mass, even if they are not overweight. In persons who have decreased muscular mass, such as some seniors, the BMI can underestimate body fat. Children and teenagers have the same BMI formula, but the number is interpreted differently depending on their age and gender.
How Is BMI Calculated?
The BMI is calculated by multiplying a person’s weight (using kilograms) with their height (using meters squared). This calculation will be done for you by our BMI calculator. The outcome will indicate the weight-group category you belong to.
- Underweight is defined as a BMI of less than 18.5 kg/m2.
- Normal weight is defined as a BMI of 18.5 to 24.9.
- Overweight is defined as a BMI of 25 to 29.9.
- Obesity is defined as a BMI of 30 or greater.
Interpretation of Results
BMI of 18.5 or less
You may need to gain weight if your BMI is less than 18.5 because you are underweight. It is suggested that you seek guidance from your doctor or a dietician.
A BMI of 18.5–24.9
You’re at a healthy weight for your height if your BMI is 18.5-24.9. You can reduce your chance of significant health problems by keeping a healthy weight.
A BMI of 25–29.9
You are mildly overweight if your BMI is between 25 and 29.9. For health reasons, you may be advised to lose weight. It is suggested that you seek guidance from your doctor or a dietician.
BMI greater than 30
You are severely overweight if your BMI is greater than 30. If you do not lose weight, your health may be jeopardized. It is suggested that you seek guidance from your doctor or a dietician.
Children And Adolescents
BMI is not related to age in adults and is the same for both sexes. BMI measurement in children and teenagers, on the other hand, is a little different. At different ages, girls and boys develop at different speeds and have varying amounts of body fat. As a result, BMI calculations during childhood and adolescence take age and gender into account.
Doctors and other health professionals do not divide children into healthy weight categories for the following reasons:
- They vary with each month of age
- Male and female body types change at distinct rates
- They change as the child grows taller
- They change as the child grows taller
Children and teenagers’ BMI is calculated in the same way as adults’ BMI is calculated: by measuring height and weight. The BMI figure and the person’s age are then entered into a sex-specific BMI-for-age chart. This will show if the child’s weight is within a healthy range.
What Is A Healthy Body Mass Index (BMI) And Weight Range?
A healthy BMI ranges from 18.5 to 24.9, which is considered “normal weight.” You can use the body mass index database from the National Institutes of Health to skip the math and check how your weight compares to your height (NIH). Depending on your height, a healthy body weight range will be different. If someone is 5’5″ and weighs 114 to 144 pounds, they are in the typical body weight range. The usual body weight range for someone 6’2″ is naturally higher: around 148 to 186 pounds.
What Does It Mean to Have a Low BMI and Body Weight?
A low BMI, sometimes known as “underweight,” is less than 18.5. Again, your ideal body weight range will be determined by your height. The average woman is 5’4″ tall; a weight of 107 or less would put her in the underweight BMI range, which can also be referred to as a low body weight range.
What Does It Mean to Have a High BMI and Body Weight?
A high BMI puts you in the category of overweight or obese. Overweight is defined as a BMI of 25.0 to 29.9, while obesity is defined as a BMI of 30.0 or higher. There is also a category called “severe obesity,” which is defined as a BMI of 40 or higher.
Side Effects Of High BMI
High BMI has been linked to a variety of health issues, according to a wide range of studies, including:
High Blood Pressure (HBP)
HBP is a condition in which men and women with higher BMIs are more likely to have hypertension than those with an average weight.
Having a BMI in the morbidly obese category (a BMI of 35 or higher) puts you at roughly twice the risk of dying from cardiovascular disease.
Diabetes Type 2
Being overweight increases your chances of developing type 2 diabetes by 50%. As BMI rises, the danger rises as well.
A greater BMI has been linked to depression symptoms and an overall sense of well-being. Obese people were 32 percent more likely than healthy-weight people to feel depressed, according to a study.
Expected Life Expectancy
Other studies have looked at death rates as a function of BMI. According to the authors of one study, BMIs between 30 and 35 reduce survival by up to four years.
Your BMI is a weight-to-height ratio that tells you how healthy you are. It’s a great technique to see if your weight is in proportion to your height in a healthy way. In fact, knowing your BMI can assist you – and your doctor – in determining any potential health concerns you may face if it falls outside the appropriate range.
