Frequently Asked Questions
Body Mass Index (BMI) is a screening tool used to assess whether a person has a healthy weight for their height. It is calculated as weight (kg) divided by height squared (m²). For imperial units: weight (lb) / height (in)² × 703. BMI provides a general indication of body fatness and is used to categorize underweight, normal weight, overweight, and obesity.
Ideal weight is a range calculated using formulas like Devine, Robinson, or Miller. The Devine formula (1974) is commonly used in medical settings. For men: 50 kg + 2.3 kg for each inch over 5 feet. For women: 45.5 kg + 2.3 kg per inch over 5 feet. These values are adjusted for height and gender, giving a target weight associated with the lowest health risks.
BMI does not distinguish between muscle and fat. Athletes with high muscle mass may have a high BMI but low body fat. For such individuals, additional measurements like waist circumference or body fat percentage are more meaningful. Always consult a healthcare professional for a complete assessment.
- Underweight: < 18.5
- Normal weight: 18.5 – 24.9
- Overweight: 25 – 29.9
- Obesity Class I: 30 – 34.9
- Obesity Class II: 35 – 39.9
- Obesity Class III: ≥ 40
The Devine formula is widely cited in clinical nutrition and pharmacology, particularly for calculating drug dosages based on ideal body weight. It's simple and has been adopted in many health guidelines. Different formulas may give slightly different results, but Devine remains the most popular.
