Weight Gain During Pregnancy

On average, 25 to 35 lbs (11.5 to 16 kg)¹. Smaller women may need a little more to store extra energy. If you started out a bit heavier, you may need to gain a little less. If you are pregnant with twins or triplets, your health care provider will suggest a healthy amount of weight to gain.

Weight gain is usually slow during the first 3 months. After this, your baby begins to grow more quickly. Although everyone is different, here is a guideline of what you can expect.

Breakdown of weight gain
Baby	6-8 lbs (2.5-3.5 kg)
Energy Stored as Fat	5-8 lbs (2 -3.5 kg)
Placenta and Amniotic Fluid	4-6 lbs (2-2.5 kg)
Blood	4 lbs (2 kg)
Breasts	2-3 lbs (1-1.5 kg)
Uterus	2-3 lbs (1-1.5 kg)
Extra Fluids	2-3 lbs (1-1.5 kg)
Total	25-35 lbs (11.5-16 kg)

You will need about 350 extra calories per day in your second trimester and an extra 450 calories per day in your third trimester¹. Satisfy this caloric intake with nutritious foods, such as a turkey sandwich, on whole wheat with mustard.

When you are pregnant, you should not try to lose weight. The weight you are gaining is due to the developing child inside of you. Dieting or reducing your portions may mean you or your child are missing out on much needed nutrients. Rather, try to make sure you are eating healthy foods full of vitamins and minerals your child may need.
