Nutrition and physical activity

Women with type 2 diabetes

A healthy weight

Try to aim for a healthy weight before becoming pregnant. A healthy eating plan and regular physical activity can help with weight management.

The weight gain recommended for pregnancy depends on your weight before you conceive. It is a good idea to have a review with a dietitian for guidance on pregnancy-specific nutrition needs and your personal weight gain target. There is some weight gain associated with a healthy pregnancy and it is generally not advisable to aim to lose weight while you are pregnant. However, you also need to take care not to 'eat for two'.

The table below shows the recommended weight gain targets for pregnancy depending on your pre-pregnancy weight range (calculated using Body Mass Index or BMI = weight (kg) / height (m) x height (m)).

Weight gain should be checked regularly throughout your pregnancy.
