FAQ
Where do the recommended ranges come from?
They're based on commonly cited Institute of Medicine (IOM) total pregnancy weight gain ranges by pre-pregnancy BMI category, spread evenly across weeks for this estimate.
Is this exact for my pregnancy?
No. It's a simplified linear estimate for general reference. Actual recommended gain patterns aren't perfectly linear, especially in the first trimester.
Is this medical advice?
No. This is an estimate only, not medical advice. Always talk with your doctor or midwife about a healthy weight gain plan for you.
