Pregnancy Weight Gain Calculator
Use our pregnancy weight gain calculator to better understand the average weight gain expected during pregnancy. Most women gain between 8kg-20kg during a pregnancy for a single baby. Please note that dieting is not recommended during pregnancy but rather a well-balanced diet.
During pregnancy your weight gain week by week and month by month can be as important as the
total amount gained. The first trimester tends to be the period with the least weight gain
and then it steadiliy increases with the greatest amount being put on in the third trimester
when your baby is growing the most. On average, an expectant mum needs an extra 300 kilojoules in her diet per day for the first trimester, 600kJ during the second trimester and 900kJ in the last trimester.
