Your rate of weight gain will depend on a variety of factors, such as your metabolism, your activity level and your genetics — just another reason why it’s important to keep up your doctor appointments throughout your pregnancy. That said, the American College of Obstetricians and Gynecologists (ACOG) offers general weight gain guidelines based on various BMI ranges (see chart below), which vary by trimester. Please check

Hi Carole, thank you for the article.

Best regards,

There should come some Norwegian figures from this study, but I'm not sure if they are published yet: https://www.fhi.no/en/studies/moba/about-moba-articles/what-is-the-norwegian-mother-and-child-cohort-study/

I found a Newspaper article claiming the study had found an avg weight gain of 9,3 kg at 30 weeks, but cannot find this data on the project website. (https://www.aftenposten.no/norge/i/EWQl3/Sa-mye-bor-du-ga-opp-nar-du-er-gravid)

Perhaps they are in a paper not published there. You can try searching the research team.

Thank you for your answer. I tried to contact the authors a while ago, but I didn't get any answer, so I had to use the USA numbers in my project due to time constraint.
