Perguntas Frequentes
What is BMI?
BMI (Body Mass Index) is a measure of body fat based on height and weight that applies to adult men and women. It is calculated by dividing weight in kilograms by height in meters squared.
What is a healthy BMI range?
A healthy BMI range for adults is typically between 18.5 and 24.9. Below 18.5 is considered underweight, 25-29.9 is overweight, and 30 or above is obese.
How do I calculate my BMI?
BMI is calculated as weight (kg) divided by height (m) squared. In imperial units: (weight in pounds × 703) ÷ (height in inches)². For example, someone 5'10" (70 inches) weighing 160 lbs has a BMI of (160 × 703) ÷ (70²) = 23.0.
What BMI is considered obese?
A BMI of 30 or higher is classified as obese. Obesity is further categorized: Class 1 (30-34.9), Class 2 (35-39.9), and Class 3 or severe obesity (40+). Higher BMI correlates with increased health risks including heart disease, diabetes, and certain cancers.
Is BMI accurate for everyone?
BMI is a useful screening tool but has limitations. It may not accurately reflect body composition for athletes, pregnant women, elderly individuals, or those with high muscle mass. Muscle weighs more than fat, so muscular people may have "overweight" BMIs despite low body fat.
What is a good BMI for my age?
BMI ranges don't change with age for adults. However, older adults may benefit from slightly higher BMIs (23-27) as some research suggests this provides protection during illness. For children and teens, BMI is age- and sex-specific using percentile charts.
How much weight do I need to lose to lower my BMI?
To lower your BMI by 1 point, you need to lose roughly 5-8 pounds depending on your height. For a 5'6" person, losing about 6 lbs drops BMI by 1. For a 6'0" person, it takes about 7.5 lbs. Use this calculator to find your target weight for a healthy BMI.
How often should I calculate my BMI?
It's recommended to check your BMI every few months if you're actively managing your weight, or annually as part of routine health monitoring.
