Understanding Weight Gain During Pregnancy: A Healthy Approach

The amount of weight you should gain during pregnancy depends on your body mass index (BMI) before you became pregnant. The Institute of Medicine provides these guidelines:

  • If you were at a normal weight before pregnancy, you should gain about 25 to 30 pounds (about 11 - 13 kilograms).

  • If you were underweight before pregnancy, you should gain between 28 and 40 pounds (between 13 & 18 kilograms).

  • If you were overweight before pregnancy, you should gain between 15 and 25 pounds (between 7 & 11 kilograms).

  • If you were obese before pregnancy, you should gain between 11 and 20 pounds (between 5 & 9 kilograms).


Check with your doctor to find out how much weight gain during pregnancy is healthy for you.
You should gain weight gradually during your pregnancy, with most of the weight gained in the last trimester. Generally, doctors suggest women gain weight at the following rate:

  • 2 to 4 pounds total during the first trimester

  • 3 to 4 pounds per month for the second and third trimesters


Recent research shows that women who gain more than the recommended amount during pregnancy and who fail to lose this weight within six months after giving birth are at much higher risk of being obese nearly 10 years later. Findings from another large study suggest that gaining more weight than the recommended amount during pregnancy may raise your child's odds of being overweight in the future. If you find that you are gaining weight too quickly, try to cut back on foods with added sugars and solid fats. If you are not gaining enough weight, you can eat a little more from each food group.

Where does the added weight go?

  • Baby – 6 to 8 pounds

  • Placenta – 1½ pounds

  • Amniotic fluid – 2 pounds

  • Uterus growth – 2 pounds

  • Breast growth – 2 pounds

  • Your blood and body fluids – 8 pounds

  • Your body's protein and fat – 7 pounds


Remember, the weight gained during pregnancy serves important purposes, such as supporting your baby's development and providing necessary resources for breastfeeding. Embrace the changes and focus on a healthy lifestyle that supports you and your baby's well-being.

Always consult with your healthcare provider for personalized advice and guidance throughout your pregnancy journey. Take care of yourself, mama!
