BMI Analysis and Interpretation
Body Mass Index (BMI) is a widely-used screening tool that estimates body fat based on height and weight measurements. While BMI has limitations, it provides a useful starting point for assessing weight-related health risks and determining appropriate weight categories. Understanding BMI calculations and interpretations helps you contextualize your results within broader health assessments and medical guidelines.
BMI Formula: Weight (kg) ÷ Height (m)² or Weight (lbs) ÷ Height (inches)² × 703. This standardized calculation allows for easy comparison across populations and medical settings.
Standard Categories: Underweight (<18.5), Normal (18.5-24.9), Overweight (25-29.9), and Obese (≥30). These categories correlate with statistical health risk assessments.
Limitations: BMI doesn't distinguish muscle from fat mass, varies by ethnicity, and may not accurately reflect health in athletes, elderly, or pregnant individuals.
Health Correlations: Higher BMIs are associated with increased risk of diabetes, cardiovascular disease, and certain cancers, though individual risk varies significantly.
Medical Context: Healthcare providers use BMI alongside other measurements like waist circumference, blood pressure, and metabolic markers for comprehensive assessment.

- • Average: 18-24% (typical for general population)
- • Above Average: 25%+ (may indicate health risks)
👩 Female Body Fat Ranges
- • Essential: 10-13% (minimum for reproductive health)
- • Athletic: 14-20% (competitive athletes and fitness enthusiasts)
- • Fitness: 21-24% (good fitness level with healthy appearance)
- • Average: 25-31% (typical for general population)
- • Above Average: 32%+ (may indicate health risks)
Metabolic Age and Health Assessment
Metabolic age compares your metabolic rate to average rates for different age groups, providing insight into your overall health and fitness level. A metabolic age lower than your chronological age suggests good health and fitness, while a higher metabolic age may indicate areas for improvement in diet, exercise, and lifestyle habits.
Metabolic Age Interpretation
Daily Calorie Needs and Metabolism
Understanding your daily calorie needs is essential for effective weight management and optimal health. Our calculator uses the Harris-Benedict formula combined with activity level multipliers to estimate your Total Daily Energy Expenditure (TDEE). This personalized approach considers your unique metabolic rate, lifestyle factors, and physical demands to provide accurate calorie recommendations for maintenance, weight loss, or weight gain goals.
🔥 Basal Metabolic Rate (BMR)
- Definition: Calories needed for basic body functions at rest
- Factors: Age, gender, weight, height, and body composition
- Percentage: 60-75% of total daily energy expenditure
- Changes: Decreases with age, increases with muscle mass
🏃 Activity Level Impact
- Sedentary: BMR × 1.2 (desk job, minimal exercise)
- Light Activity: BMR × 1.375 (light exercise 1-3 days/week)
- Moderate: BMR × 1.55 (moderate exercise 3-5 days/week)
- High Activity: BMR × 1.725+ (intense exercise 6-7 days/week)
⚖️ Weight Management
- Maintenance: Consume calories equal to TDEE
- Weight Loss: Create deficit of 500-1000 calories/day
- Weight Gain: Add 300-500 calories above TDEE
- Monitoring: Adjust based on actual results over time
