Weight Gain in the Third Trimester

During your third trimester, weight gain should be steady and gradual, continuing at about the same rate as in your second trimester.

The average weight gain now is around 0.2 to 0.5 kilograms or 0.5 to 1.0 pounds per week. If you're gaining more, see the guidelines in Eating Well with Canada’s Food Guide and compare your eating habits. You can also check out Health Canada's information about following the Food Guide during pregnancy and breastfeeding.

Weight loss and dieting are not recommended during pregnancy. Focus on healthy eating and healthy foods, not your weight.  For more information, talk with your healthcare provider or call 8-1-1 to speak to Dietitian Services at HealthLink BC.

An active lifestyle is also important for a healthy weight gain during pregnancy. Be sure to ask your doctor or midwife about exercising during pregnancy.
