How many extra calories do I need per day during pregnancy?

Pregnancy does not mean you need to eat for two or double your daily meals; the common concept of "eating for two" can lead to unhealthy weight gain. The actual need for extra calories depends primarily on the stage of pregnancy, your pre-pregnancy weight, and your daily physical activity. The primary goal is to provide your baby with the nutrients necessary for growth and development, while maintaining a healthy weight for the mother that reduces the risk of complications such as gestational diabetes or the need for a C-section [2], [3].

Calorie Distribution by Pregnancy Trimester

Your energy needs vary significantly as pregnancy progresses, as the requirements of the fetus and the changes in maternal tissues evolve:

• First Trimester (Months 1-3): You often do not need extra calories; the fetus is in the early stages of formation and does not require large amounts of energy [1], [2].
• Second Trimester (Months 4-6): Your energy needs begin to increase to support fetal growth and changes in your body; you typically need about 340 extra calories per day [1], [3].
• Third Trimester (Months 7-9): Your needs reach their peak, where you may need about 450 extra calories per day. However, in the final weeks of pregnancy, your need for these extra calories may decrease [1], [2].

Quality is More Important Than Quantity

It is essential that these extra calories come from nutrient-dense sources, not from "empty calories" found in sugars, sweetened beverages, and fast food. You should focus on proteins, whole grains, healthy fats, and vegetables to ensure you and your baby get the necessary vitamins and minerals.

Influencing Factors and Important Tips

Remember that these numbers are general guidelines. If your pre-pregnancy weight is below or above the normal range, your doctor may recommend a different weight gain plan. The goal is to gain weight slowly and gradually [2]. For example, women with a normal weight before pregnancy are generally recommended a total weight gain of 11 to 16 kilograms (25 to 35 pounds) throughout the pregnancy [3].

If you are experiencing nausea that prevents you from eating, or if you have an abnormal craving to consume non-food items (such as dirt or ice), known as "pica," you must inform your doctor immediately, as this may be an indicator of a severe iron deficiency or other nutrient deficiencies [3]. Always avoid self-diagnosis and consult your healthcare provider regularly to adjust your nutritional plan to fit your individual needs and your baby's growth [1], [3].
