How much weight should I gain with twins?

If you're expecting twins, should you eat more and gain more weight than with a single pregnancy?


If you’re pregnant with twins, you will certainly need to consume more calories than for a single pregnancy. But rather than aim for a certain intake per day, try and be guided by your appetite. 


The same rules on healthy eating apply no matter how many babies you are carrying. Ensure that you eat:

  • plenty of fresh fruit and vegetables
  • wholegrain starchy foods such as bread and cereal
  • dairy foods such as milk, cheese and yoghurt
  • protein-rich foods such as lean meat, chicken and fish, including up to two portions of oily fish a week.

Your midwife may also advise you to take a pregnancy vitamin and mineral supplement.

Weight gain varies between individuals, but on average a woman expecting one baby gains around 11-15kg. For a twin pregnancy, a weight gain of about 16-20kg is usual.


Your weight will be monitored throughout your pregnancy and the regular scans you have will keep a close check on your unborn babies’ growth.
