About Pregnancy Weight Gain

Talking to your doctor about your weight gain is important. Try not to worry if you're slightly above or below these weights. Working with your doctor on food intake will get you on track.

Facts About Weight Gain

  • The American College of Obstetricians and Gynecologists recommends a weight gain of 25 to 35 pounds during pregnancy, for women who are at normal weight when pregnancy occurs.
  • Women who are underweight should gain 28 to 40 pounds, unless your doctor says differently.
  • Women who are overweight should gain 15 to 25 pounds, unless your doctor says differently.
  • Women who are obese should gain 11 to 20 pounds, unless your doctor says differently.
  • Eating low fat meals will allow you to gain weight correctly for your pregnancy. Putting on weight that is unnecessary is easy to do when eating junk food and foods that are higher in fat.
  • Eating a well-rounded diet is important. According to the American College of Obstetricians and Gynecologists, pregnant women should have 4 servings of milk, 3 to 4 servings of protein (2 to 3 from animal and 1 to 2 from legumes/nuts), 5 servings of fruits and vegetables (2 of Vitamin C, 2 of Vitamin A, and 1 of another), 4 servings of whole grain products, and 2 servings of other.
