What Is BMI and Waist Circumference?

BMI (Body Mass Index) is a measure of body fat based on your weight relative to your height. It categorizes you into underweight, normal weight, overweight, or obese, providing a general assessment of your overall body health.

Waist Circumference measures abdominal fat, which is a key indicator of health risks such as heart disease, diabetes, and metabolic syndrome. Unlike BMI, it focuses on fat distribution rather than overall weight.

Calculation Formula

BMI Formula:$$BMI = \frac{\text{Weight (kg)}}{\text{Height (m)}^2}$$BMI=Height (m)2Weight (kg)​

or$$BMI = \frac{\text{Weight (lb)} \times 703}{\text{Height (in)}^2}$$BMI=Height (in)2Weight (lb)×703​

Waist Circumference Risk Categories:

• Men:
  • Low risk: < 94 cm (<37 in)
  • Increased risk: 94–102 cm (37–40 in)
  • High risk: > 102 cm (>40 in)
• Women:
  • Low risk: < 80 cm (<31.5 in)
  • Increased risk: 80–88 cm (31.5–35 in)
  • High risk: > 88 cm (>35 in)

The calculator combines BMI and waist circumference to provide a more complete health assessment.

Practical Example

Suppose a man weighs 85 kg and is 175 cm tall with a waist circumference of 100 cm:

1. BMI Calculation:

$$BMI = \frac{85}{1.75^2} = \frac{85}{3.0625} \approx 27.7$$BMI=1.75285​=3.062585​≈27.7

BMI Category: Overweight

2. Waist Circumference Risk:
   Waist = 100 cm → Increased Risk

Combined Interpretation:
BMI indicates overweight, and waist circumference shows increased risk for obesity-related diseases. This person should consider lifestyle changes to reduce weight and abdominal fat.
