BMR Calculation Method
Mifflin-St Jeor Equation
For Men: BMR = 10 × weight(kg) + 6.25
× height(cm) - 5 × age(years) + 5
For Women: BMR = 10 × weight(kg) + 6.25
× height(cm) - 5 × age(years) - 161
Your calculation: BMR = 10 × 70 + 6.25 × 175 - 5 × 30 + 5 = 1,649 calories/day
Daily calories: 1,649 × 1.55 = 2,556 calories/day
Important Notes
📊 Accuracy
BMR calculations are estimates. Individual metabolism can vary by ±10-15% due to genetics, muscle mass, and other factors.
