Question 1

What is BMI and how is it calculated?

Accepted Answer

BMI (Body Mass Index) is a measure of body fat based on height and weight. It's calculated by dividing weight in kilograms by height in meters squared (kg/m²). For imperial units, the formula is (weight in pounds / (height in inches)²) × 703.

Question 2

What are the BMI categories?

Accepted Answer

BMI categories are: Underweight (below 18.5), Normal weight (18.5-24.9), Overweight (25-29.9), and Obese (30 and above). These ranges apply to most adults aged 20 and older.

Question 3

Is BMI accurate for everyone?

Accepted Answer

BMI is a useful screening tool but has limitations. It doesn't distinguish between muscle and fat mass, so athletes or very muscular people may have high BMI despite being healthy. It's also less accurate for elderly people, children, and pregnant women.

Question 4

Should I be concerned about my BMI result?

Accepted Answer

BMI is just one indicator of health. If your BMI is outside the normal range, consider consulting with a healthcare provider who can assess your overall health, including other factors like muscle mass, bone density, and overall fitness.

Question 5

How often should I check my BMI?

Accepted Answer

For most people, checking BMI monthly or quarterly is sufficient. If you're actively trying to lose or gain weight, you might check more frequently, but remember that healthy weight changes happen gradually over time.
