Explanation: BMI correlates fairly well with body fat in most people, though it doesn't directly measure body fat.
Details: BMI is important because it helps identify potential weight problems in adults. However, it should be used as a screening tool, not a diagnostic of body fatness or health.
Tips: Enter your weight in kilograms and height in meters. For accurate results, measure your height without shoes and weight with minimal clothing.
Q1: What is a healthy BMI range?
A: For adults, 18.5-24.9 is considered healthy. Below 18.5 is underweight, 25-29.9 is overweight, and 30+ is obese.
Q2: Is BMI different for women and men?
A: The same BMI ranges apply to both, though women tend to have more body fat than men at the same BMI.
Q3: How often should I check my BMI?
A: For most adults, checking every few months is sufficient unless you're actively trying to lose or gain weight.
Q4: What are BMI limitations?
A: BMI may overestimate body fat in athletes and underestimate it in older people who have lost muscle mass.
Q5: What's the best way to lose weight?
A: A combination of healthy eating (calorie deficit) and regular physical activity is most effective for sustainable weight loss.
