Understanding Your BMI
BMI (Body Mass Index) is an important screening tool used to determine whether a person is at a healthy weight for their height. It's a simple calculation that can help identify potential weight issues and health risks.
BMI Categories:
- Underweight: Less than 18.5
- Normal weight: 18.5 to 24.9
- Overweight: 25 to 29.9
- Obese: 30 or greater
While BMI is a useful starting point, it should not be the only factor considered when assessing your health. Factors such as muscle mass, bone density, age, sex, ethnicity, and lifestyle should also be taken into account.
Frequently Asked Questions
What is BMI?
Body Mass Index (BMI) is a simple measure that uses your height and weight to work out if your weight is healthy. It's calculated by dividing your weight in kilograms by the square of your height in meters.
What are the BMI categories?
The BMI categories are: Underweight (under 18.5), Normal weight (18.5 to 24.9), Overweight (25 to 29.9), and Obese (30 or above).
Is BMI accurate for everyone?
BMI is not a perfect measure. It may not be accurate for athletes, elderly people, or during pregnancy. It doesn't account for factors like muscle mass, bone density, age, and gender.
How often should I check my BMI?
It's recommended to check your BMI whenever there are significant changes in your weight or every 6-12 months as part of your regular health check-up.
