Pregnant woman cautiously stepping on scales

When you’re pregnant, you should gain weight. Your baby needs nutrients and kilojoules to develop healthily and grow normally. You need them for your own health, too.

It is normal to gain weight during pregnancy as your baby grows and your body changes to support your baby’s development and prepare for breastfeeding. However, gaining too much weight can put you at risk of gestational diabetes, can make it harder to lose weight after you have the baby and can put your baby at greater risk of becoming overweight or developing metabolic syndrome later in life.

This means it’s very important to choose foods that are nutrient dense but not energy dense. Go for quality not quantity, limit discretionary foods and choose foods from the five food groups.
