Calculations
How calorie targets are calculated.
RepBite AI uses the Mifflin-St Jeor equation to estimate BMR, applies an activity multiplier to estimate TDEE, then adjusts the result based on your goal.

BMR
1778 kcal
TDEE
2133 kcal
Target
1813 kcal
Step-by-step calculation
1. Formula used
Mifflin-St Jeor Equation
2. BMR
BMR = 10 × 86 + 6.25 × 170 - 5 × 30 + 5
3. BMR result
BMR = 1778 kcal/day
4. Activity multiplier
sedentary multiplier = 1.2
5. TDEE
TDEE = 1778 × 1.2 = 2133 kcal/day
6. Goal adjustment
Goal multiplier = 0.85
7. Final calorie target
Target = 2133 × 0.85 = 1813 kcal/day
Formula reference
Mifflin-St Jeor BMR: BMR = 10 × weight(kg) + 6.25 × height(cm) - 5 × age + S
S = +5 for male, -161 for female.
TDEE: TDEE = BMR × activity multiplier
Goal target: Target calories = TDEE × goal multiplier
