Congratulations! Eating correctly when you are pregnant is one of the most important steps to building a healthy baby. Your body provides your fetus with everything it needs. You need to eat for both your health and your child’s health.
However, you are not eating for two! You should only increase your calorie consumption by a few hundred calories a day. You don’t want to gain too much weight during your pregnancy (and it doesn’t magically melt off once you deliver).
Make every calorie count and even do double duty to provide your baby with everything you need to stay healthy. This is not an exhaustive discussion but covers the highlights.
