BMI (Body Mass index) and BRI (Body Roundess Index) indicate your health risk based on height, weight and/ waist line

BMI (Body Mass Index)
- Definition: A measure of body fat based on your weight relative to your height. It’s a quick and straightforward way to assess whether your weight is in a healthy range.
- Formula: BMI=weight (kg)height (m)2BMI = \frac{\text{weight (kg)}}{\text{height (m)}^2}BMI=height (m)2weight (kg)
- Ranges:
- Underweight: BMI < 18.5
- Normal weight: BMI = 18.5–24.9
- Overweight: BMI = 25–29.9
- Obese: BMI ≥ 30
- Meaning:
- Lower BMI values suggest being underweight, which may indicate malnutrition or other health risks.
- Higher BMI values indicate overweight or obesity, which are associated with increased risks of heart disease, diabetes, and other health conditions.
BRI (Body Roundness Index)
- Definition: A newer metric that estimates body fat and health risks based on waist circumference and height. It provides a more direct measure of body fat distribution compared to BMI.
- Formula: BRI=364.2−365.5×1−(waist circumference (m)2π×height (m))2BRI = 364.2 - 365.5 \times \sqrt{1 - \left(\frac{\text{waist circumference (m)}}{2\pi \times \text{height (m)}}\right)^2}BRI=364.2−365.5×1−(2π×height (m)waist circumference (m))2
- Ranges:
- Healthy: BRI < 4.9
- At Risk: BRI ≥ 4.9
- Meaning:
- A healthy BRI suggests appropriate body fat levels.
- A high BRI indicates excess fat and potential health risks, especially related to visceral fat (fat around internal organs).
