Your Results

When will you gain the weight?

  • Most women can expect to gain about 1 to 2 kg (about 2 to 4 lbs) in the first trimester.
  • Most weight gain happens gradually during the second and third trimesters. However, a sudden peak in the rate of weight gain during the second trimester is not unusual.

What can you do to gain a healthy amount of weight during pregnancy?

  • Talk to your health care provider early in your pregnancy about what you can expect and to set a weight gain goal.
  • Eat "twice as healthy", not "twice as much". In most cases, just a little more food is enough. Follow the recommendations in Canada's Food Guide.
  • Add up activities in periods of at least 10 minutes, for a total of 30 minutes of activity each day.
  • Activities such as walking, gardening, housework, and swimming can be done safely during pregnancy.
  • Talk to your health care provider before increasing your activity level or before starting an exercise program.

The above recommended weight gain can be used as a general guide for single pregnancies. The Pregnancy Weight Gain Calculator should not replace individualized medical advice.
