When you are pregnant, your body forms a growing baby and lays down extra stores for breast feeding later on. As well as needing extra fuel for your own body and your growing baby, more nutrients are required for the increased tissues of the uterus, placenta and blood cells. You may notice your appetite increases to ensure you eat enough for you and your baby. This doesn’t mean you need to eat for two! In fact, gaining too much weight when you’re pregnant may cause pregnancy complications such as high blood pressure, gestational diabetes and a larger baby.
In the first 12 weeks of pregnancy, you generally don’t need any extra food than usual, just try to eat a variety of nutritious foods every day.
You'll need to eat a little extra food over the 2nd and 3rd trimesters, but choose nutritious foods to ensure you achieve a healthy weight gain during pregnancy that is within the recommendations provided by your health professional.
If you started your pregnancy at a healthy weight, although you don’t need to start counting calories, the extra energy you need each day is around 1400kJ in your 2nd trimester, and 1900kJ in your 3rd trimester.
Here are some examples of the extra food you need to eat each day, just choose one per day, in addition to your normal diet:
As you can see, you don't need to 'eat for two,' but a little extra nutritious food each day will make sure you keep up the energy and nutrients needed for your growing baby!
Remember gaining an appropriate amount of weight is a normal part of pregnancy and helps to achieve a healthy outcome for you and your baby. An appropriate weight gain during pregnancy, if you have a healthy weight Body Mass Index (BMI) before becoming pregnant, is approximately 11.5kg to 16kg, but can vary significantly from one woman to another. If you were underweight before pregnancy, you may need to gain more weight. If you were overweight, then you may need to gain less. Talk to your midwife or doctor about the right amount of weight to gain during pregnancy, this amount is different for every person.
