How Will My Weight Change in Pregnancy?

Eating for yourself and growing a baby will change your weight. That’s why gaining weight is a normal and healthy part of pregnancy.  

It’s important to remember:

  • The amount of weight gain is different for each person.
  • It can be hard to control exactly when or how fast you gain weight.
  • Most of the weight comes from your baby, the placenta, amniotic fluid, and extra blood your body makes.

What’s the Right Amount of Weight to Gain?

The amount of weight to gain depends on your weight and height before pregnancy. Talk with your provider or a registered dietitian about the best weight gain for your body.

General guidelines are that you should gain:

  • 28 to 40 pounds if you are underweight
  • 25 to 35 pounds if you are average weight
  • 15 to 25 pounds if you are overweight
  • 12 to 20 pounds if you are very overweight

If you have twins, you may need to gain more weight.

Tips for Healthy Weight Gain

  • Eat small meals and snacks every three to four hours during the day. Our guide to healthy eating can tell you more about healthy diet choices.
  • Drink water, seltzer, unsweetened flavored water, and diet sodas.
  • Choose high-protein and high-fiber foods like whole wheat carbs, nonfat Greek-style yogurt, unsalted nuts, or reduced-fat cheeses.
  • Pair a fruit or vegetable with protein (like nuts, cheese, yogurt, beans, or eggs) to keep you satisfied between meals.
  • Use only small portions of fats like butter, sour cream, mayonnaise, and salad dressing.
  • Avoid or limit how often you eat deep fried foods.
  • Limit sweets like candy, baked goods, sodas, juices, and fruit smoothies.
  • Exercise regularly. See our tips for exercise in pregnancy.
