Formula:
This calculator determines your recommended pregnancy weight gain range based on your Pre-Pregnancy Body Mass Index (BMI). While active weight loss is generally not recommended during pregnancy, managing weight to minimize gain is crucial for those who are overweight or obese.
BMI Formula:
BMI = Weight (kg) / [Height (m)]2
OR
BMI = [Weight (lbs) / Height (inches)2] * 703
Recommended Total Weight Gain During Pregnancy (for singleton pregnancies):
- Underweight (BMI < 18.5): 12.5 - 18 kg (28 - 40 lbs)
- Normal Weight (BMI 18.5 - 24.9): 11.5 - 16 kg (25 - 35 lbs)
- Overweight (BMI 25.0 - 29.9): 7 - 11.5 kg (15 - 25 lbs)
- Obese (BMI ≥ 30.0): 5 - 9 kg (11 - 20 lbs)
These are general guidelines. Always consult your healthcare provider for personalized advice.
