What is the recommended caloric increase during pregnancy?

During pregnancy, an additional caloric intake of approximately 300-400 kcal per day is recommended to support the increased metabolic demands of both the mother and the developing fetus. This caloric increase helps ensure that the mother has enough energy to support the changes her body undergoes during pregnancy, including increased tissue growth, fetal development, and preparing for breastfeeding.

The recommended range of 300-400 kcal is important because it allows for a healthy weight gain during pregnancy, which is crucial for both maternal and fetal health. It is also significant to note that the types of calories consumed during this period should prioritize nutrient-dense foods that provide essential vitamins and minerals necessary for the baby's growth and development.

The other options do not align with current nutritional guidelines for pregnant individuals. A caloric increase that is too low may not meet the metabolic demands during this critical period, while an excessive increase can lead to excessive weight gain, which may pose risks for both the mother and the child.
