Formula Used in WW Weight Watchers Calculator
This calculator uses scientifically accepted formulas to estimate energy needs.
1. BMR Formula (Mifflin-St Jeor Equation)
BMR is the number of calories your body needs at rest.
For Males & Females:
First convert weight from pounds to kilograms:
Weight (kg) = Weight (lbs) × 0.453592
Then:
BMR Formula:
BMR = (10 × weight in kg) + (6.25 × height in cm) − (5 × age) + gender adjustment
- Male: +5
- Female: −161
Example:
- Weight: 150 lbs (68.04 kg)
- Height: 170 cm
- Age: 25
- Gender: Female
Calculation:
BMR = (10 × 68.04) + (6.25 × 170) − (5 × 25) − 161
BMR = 680.4 + 1062.5 − 125 − 161
BMR = 1456.9 kcal/day
2. TDEE Formula (Total Daily Energy Expenditure)
TDEE includes daily activity level.
Formula:
TDEE = BMR × Activity Level
Example:
If BMR = 1456.9
Activity Level = 1.55 (Moderate)
TDEE = 1456.9 × 1.55
TDEE = 2258 kcal/day
3. WW Points Formula (Estimated)
Weight Watchers points are estimated using calorie conversion.
Formula:
WW Points = TDEE ÷ 35
Example:
TDEE = 2258
WW Points = 2258 ÷ 35 = 65 Points
Example Calculation Table
| Parameter | Value |
|---|---|
| Weight | 150 lbs |
| Height | 170 cm |
| Age | 25 |
| Gender | Female |
| Activity Level | Moderate (1.55) |
| Result | Value |
|---|---|
| BMR | 1457 kcal |
| TDEE | 2258 kcal |
| WW Points | 65 |
Understanding BMR, TDEE & WW Points
What is BMR?
BMR represents the calories your body burns while at rest for essential functions like:
- Breathing
- Blood circulation
- Cell production
- Organ function
What is TDEE?
TDEE is your total calorie burn including:
