26 Sep 2019 --- Obese pregnant women do not need to add any calories to their daily diet to gain the recommended five to nine kilograms, as this may cause health issues for both mother and baby. This is according to a new study from Louisiana State University’s (LSU) Pennington Biomedical Research Center. Current guidelines suggest a 200 to 300 calorie increase during the second and third trimester, which the new study says should not apply to obese mothers. Such guidelines were not based on research involving actual obese pregnant women, note the researchers, while they highlight that their findings mark the first dietary intake recommendations for pregnant women with obesity, based on a study involving such subjects.
