Verified Biometric Equations, Body Fat Estimation & Vital Calculators. Calculate basal metabolic burn, visualize TDEE energy curves, and optimize hydration targets with clinical formula precision.
Engineered with peer-reviewed sports science and clinical nutrition formulas to provide transparent, accurate biometric insight.
Calculate your Body Mass Index (BMI) using WHO & CDC clinical standards. Includes healthy weight range, weight category gauge, and target weight estimation.
Compare clinical healthy weight benchmarks using 4 gold-standard medical equations: Devine, Robinson, Miller, and Hamwi formulas.
Calculate estimated body fat percentage and lean muscle mass using the official US Navy circumference method with anatomical tape measurements.
Calculate your Total Daily Energy Expenditure using the Mifflin-St Jeor formula. Accurately determines daily maintenance calories across all activity levels.
Plan safe, sustainable fat loss with scientifically verified calorie deficit targets. Visualizes daily caloric intake, weekly loss rates, and target timeline.
Calculate optimal daily grams of Protein, Carbohydrates, and Dietary Fats tailored for fat loss, muscle building, or athletic maintenance with interactive charts.
Determine the exact number of baseline calories your body expends purely to stay alive at complete rest, using the revised Mifflin-St Jeor metabolic model.
Estimate your personalized daily hydration requirement based on body mass, physical exercise duration, and climate temperature.
Plan and track intermittent fasting protocols (16:8 Leangains, 18:6 Warrior, 14:10 Circadian, or 20:4) with customizable eating windows and fasting milestones.
Calculate aerobic training thresholds and Karvonen heart rate zones (Warm-up, Fat Burn, Aerobic, Anaerobic, and VO2 Max) based on age and resting pulse.
How Gomen Biometrics ensures biometric reliability, data privacy, and mathematical rigor.
We deploy validated formulas including Mifflin-St Jeor (AJCN 1990), Devine IBW, US Navy Body Fat, and Karvonen heart rate zones. No proprietary black boxes.
All biometric calculations run 100% client-side in your local web browser. Your body weight, measurements, and age are never recorded in remote databases.
Every tool details statistical standard errors of estimate and clinical caveats, ensuring you understand the physiological context of every number.
Adjust biological variables in real time with interactive Chart.js visualizations, metric/imperial unit conversions, and personalized recommendations.
Everything you need to know about physiological formulas, accuracy standards, and health metrics on Gomen Biometrics.
