Pregnancy weight gain
IOM-style ranges as education, not a target.
Educational only. Not a diagnosis, not a substitute for your clinician.
These are widely cited educational ranges for singleton pregnancies, by starting BMI. Your clinician may set a different plan (twins, underweight, diabetes).
- BMI under 18.5: about 12.5–18 kg
- BMI 18.5–24.9: about 11.5–16 kg
- BMI 25–29.9: about 7–11.5 kg
- BMI 30+: about 5–9 kg
