Epidemiological evidence that severe obese women (pre-pregnancy BMI≥40 kg/m 2 ) should lose weight during their pregnancy. J Matern Fetal Neonatal Med. 2021 May 24:1-6. doi: 10.1080/14767058.2021.1918666. Epub ahead of print. PMID: 34030588. Table 1: Comparisons between the current international recommendations for gestational weight gain (IOM 2009), and the linear equation. Being a linear equation, each woman may be considered as a single plot, and the calculations are then individualized. IOM 2009 recommendations seem to be inadequate for underweight women, and on the other side for obese, beginning at 32 kg/m². Especially, from 36 kg/m² and upward, women should LOSE weight for this pregnancy. We have validated this linear curve until 40-41 kg/m², as we did not had in our cohort enough morbid obese women (over 40 kg/m²). Moreover, and especially, we had not enough women who had actually lost weight during their pregnancy to test it (if we extrapolate this curve, a woman with a pre-pregnancy BMI of 45 kg/m² should lose 12 kg).
