Understanding Your BMI
What is BMI?
Body Mass Index (BMI) is a simple index of weight-for-height that is commonly used to classify underweight, overweight and obesity in adults.
BMI Categories
BMI values are grouped into categories: Underweight, Normal weight, Overweight, and Obesity classes I, II and III.
Limitations
BMI doesn't account for muscle mass, bone density, overall body composition, and racial and sex differences.
Health Indicator
While not a direct measure of body fat, BMI is a useful screening tool for weight categories that may lead to health problems.

Understanding BMI for Weight Management
How BMI is Calculated
Body Mass Index (BMI) is calculated by dividing a person's weight in kilograms by the square of their height in meters (kg/m²). The formula is the same for both adults and children, though the interpretation differs for children.
Imperial Formula: BMI = [weight (lbs) / [height (in)]²] × 703
For example, a person who weighs 70 kg and is 1.75 m tall would have a BMI of:
70 / (1.75 × 1.75) = 22.9
This falls within the normal weight category (18.5-24.9).
Using BMI for Weight Management
BMI serves as a useful starting point for weight management discussions with healthcare providers. Here's how to interpret your BMI results:
Underweight
Focus on healthy weight gain through nutrient-dense foods and strength training
Normal Weight
Maintain your weight through balanced nutrition and regular physical activity
Overweight
Aim for gradual weight loss through calorie control and increased activity
Obesity
Consult a healthcare provider for a comprehensive weight management plan
Beyond BMI: Other Health Indicators
While BMI is a useful screening tool, it's important to consider other factors for a complete picture of your health:
Waist Circumference
- Measures abdominal fat
- Higher values indicate increased health risks
- Men: >40 inches, Women: >35 inches
Body Composition
- Percentage of body fat vs. muscle
- More accurate than BMI alone
- Can be measured with specialized scales
Remember: BMI is just one indicator of health. A comprehensive approach considers diet, physical activity, sleep, stress management, and other lifestyle factors.
