How much to walk according to BMI calculator

What is a BMI calculator?

A BMI (Body Mass Index) calculator is a tool that allows individuals to determine their BMI, a measure of body fat based on height and weight. The formula for BMI is the individual's weight in kilograms divided by the square of their height in metres. The result is a numerical value, and this value is then used to categorise individuals into different BMI ranges, such as underweight, normal weight, overweight, or obesity.

Here is the general formula for calculating BMI:

BMI= ​weight(kg)/weight(kg)2

For adults, the BMI categories are typically defined as follows:

• Underweight: BMI less than 18.5
• Normal weight: BMI between 18.5 and 24.9
• Overweight: BMI between 25 and 29.9
• Obesity: BMI 30 or greater

For children and teens aged 2 to 19, the BMI-for-age percentile is used to account for growth patterns and to categorize individuals based on their relative position compared to others of the same age and sex.

Many online BMI calculators are available where you can input your weight and height, and the calculator will provide your BMI along with an interpretation of the result. It's important to note that while BMI is a widely used measure, it does have limitations, as it does not directly measure body fat distribution or distinguish between muscle and fat. Additionally, BMI may not be as accurate for certain populations, such as athletes with high muscle mass.

BMI chart for children and teens, age 2-20

Body Mass Index (BMI) is a measure of body fat based on height and weight. For children and teens aged 2 to 20, BMI is calculated differently than for adults, as it takes into account the growth patterns that occur during childhood and adolescence. The BMI-for-age percentile is used to assess how a child's BMI compares to others of the same age and sex.

The BMI-for-age percentile is categorized into the following ranges:

• Underweight: Less than the 5th percentile
• Normal weight: 5th percentile to less than the 85th percentile
• Overweight: 85th percentile to less than the 95th percentile
• Obesity: Equal to or greater than the 95th percentile

It's important to note that BMI is just one indicator of health, and it does not directly measure body fat. Other factors such as muscle mass, distribution of fat, and overall health should be considered in a comprehensive health assessment.

Here's an example of how the BMI-for-age percentile is categorized:

• Percentile Range BMI Category

• Less than 5th Underweight

• 5th to less than 85th Normal weight

• 85th to less than 95th Overweight

• Equal to or greater than 95th Obesity

To determine the BMI-for-age percentile for a specific child or teen, you would typically use BMI calculator men designed for this age group or refer to growth charts provided by health organizations. These charts are often available through healthcare providers, and they take into account age, sex, height, and weight to provide a percentile ranking.
