BMI Calculator FAQ
What is BMI and how is it calculated?
BMI (Body Mass Index) is a measure of body fat based on height and weight. It's calculated by dividing your weight in kilograms by your height in meters squared (kg/m²). BMI provides a general indication of whether you're underweight, normal weight, overweight, or obese.
Is BMI accurate for everyone?
BMI has limitations and may not be accurate for athletes, bodybuilders, pregnant women, elderly people, or children. It doesn't distinguish between muscle and fat mass, so muscular individuals may have a high BMI despite being healthy.
What are the BMI categories and their health implications?
Underweight (<18.5): May indicate malnutrition. Normal (18.5-24.9): Associated with lowest health risks. Overweight (25-29.9): Increased risk of health problems. Obese (≥30): Higher risk of diabetes, heart disease, and other conditions.
How often should I check my BMI?
Check your BMI monthly or whenever your weight changes significantly. It's more useful to track trends over time rather than focusing on daily fluctuations. Use it alongside other measurements like body fat percentage for a complete picture.
Can BMI help me set weight loss goals?
Yes, BMI can help you understand your current weight status and set realistic goals. Our calculator shows your ideal weight range and how much weight you'd need to lose or gain to reach the normal BMI category.
What should I do if my BMI indicates I'm overweight or obese?
Consult with a healthcare provider for personalized advice. Generally, focus on gradual weight loss through a balanced diet and regular exercise. Our meal planning and fitness tools can help you create a sustainable plan.
