About Anthropometric Measurements

BMI (Body Mass Index): A measure of body fat based on height and weight. BMI categories: Underweight (<18.5), Normal (18.5-24.9), Overweight (25-29.9), Obese (≥30). While useful for population studies, BMI doesn’t distinguish between muscle and fat mass.

WHR (Waist-to-Hip Ratio): Indicates body fat distribution and health risks. A higher WHR suggests more abdominal fat, which is linked to increased cardiovascular disease and diabetes risk. Healthy ranges: Men <0.9, Women <0.8.

Body Fat Percentage: The percentage of your total body weight consisting of fat tissue. More accurate than BMI for assessing body composition. Essential fat levels: Men 2-5%, Women 10-13%. Athletic ranges: Men 6-13%, Women 14-20%.

US Navy Body Fat Formula: Uses waist, neck, and hip (for women) measurements with height to estimate body fat percentage. Developed by the U.S. Navy for fitness assessments, it’s more accessible than underwater weighing or DEXA scans.

BMR (Basal Metabolic Rate): The number of calories your body needs at complete rest to maintain vital functions like breathing, circulation, and cell production. Represents 60-75% of total daily energy expenditure for sedentary individuals.

TDEE (Total Daily Energy Expenditure): Your BMR multiplied by activity level factor. This represents the total calories you burn in a day including exercise, daily activities, and digestion. Essential for weight management planning.

Body Frame Size: Determined by wrist circumference relative to height, indicating bone structure. Small, medium, or large frame sizes help determine healthy weight ranges. People with larger frames typically have higher healthy weight ranges.

Ideal Weight Formulas: Devine Formula (1974) and Robinson Formula (1983) calculate ideal body weight based on height and gender. Originally developed for drug dosing, they’re now used for general health assessment and goal setting.

Body Surface Area (BSA): Calculated using the DuBois formula, BSA is used in medical settings for drug dosing and metabolic studies. It correlates better with metabolic rate than body weight alone.

Lean Body Mass: Your total body weight minus fat mass, including muscles, bones, organs, and water. Higher lean body mass correlates with better metabolism, strength, and overall health outcomes.

Health Note: These measurements provide valuable health insights but should be interpreted alongside other factors like medical history, fitness level, and overall well-being. Consult healthcare professionals for comprehensive health assessments.
