A new study just published in the International Journal of Obesity has found that while most women gain weight after each pregnancy, that breastfeeding can reduce this weight gain. The study of more than 740 000 postmenopausal women found that body mass index (BMI) increased progressively with the number of births the women had. However, regardless of the number of pregnancies a woman had, BMI was lower in those who had breastfed. The researchers estimated that for every 6 months they had breastfed, their BMI was 1% lower. These findings were independent of socioeconomic group, smoking and physical activity. Read more about the study here.
