Weight Loss Calculation Formulas
Our calculator uses scientifically validated formulas for accurate weight loss predictions and metabolic calculations. Understanding these formulas helps you make informed decisions about your weight loss journey.
📊 Core Calculation Formulas
Body Mass Index (BMI)
Calculate current and target BMI for health assessment
Total Daily Energy Expenditure (TDEE)
Women: BMR = 10 × weight + 6.25 × height - 5 × age - 161
TDEE = BMR × Activity Factor (1.2-1.9)
Mifflin-St Jeor equation for metabolic rate calculation
Calorie Deficit for Weight Loss
Target Intake = TDEE - Daily Deficit
Based on 7700 calories per kilogram of body fat
Weight Loss Timeline
Plateau Prediction = Timeline × 0.4 (typically 6-8 weeks)
Realistic timeline with plateau modeling
