Preventing obesity during pregnancy is essential for both maternal and fetal health. Research indicates that excessive weight gain during pregnancy increases the risk of gestational diabetes, preeclampsia, and future obesity in children. To reduce these risks, it is crucial for expectant mothers to adopt healthy prenatal strategies. A balanced diet, rich in fruits, vegetables, lean proteins, and whole grains, along with moderate physical activity, is essential. Pregnant women should also focus on controlling their weight gain within recommended guidelines, avoiding overeating, and managing emotional eating habits. Prenatal obesity prevention education should be integrated into prenatal care programs to help mothers understand the importance of healthy weight gain and proper nutrition. Early intervention can lead to better health outcomes for both the mother and the child, reducing the likelihood of obesity-related complications in the future.
