Pregnancy brings a lot of changes—and plenty of questions. One of the most common is: How much weight should I gain during pregnancy?

There isn’t one number that’s right for everyone. Healthy pregnancy weight gain depends largely on your body mass index (BMI) before becoming pregnant, along with factors such as whether you’re carrying one baby or multiples and your individual health needs.

For most women carrying one baby, recommended pregnancy weight gain ranges from about 11 to 40 pounds, depending on pre-pregnancy BMI.

How Much Weight Should You Gain During Pregnancy?

The Centers for Disease Control and Prevention recommends the following weight gain ranges for women pregnant with one baby:

Your healthcare provider can calculate your BMI at your first prenatal appointment and help determine an appropriate weight-gain goal for you.

These numbers are guidelines—not a test you have to pass. Your provider will consider your weight gain along with your baby’s growth and your overall health.

How Much Weight Should You Gain in the First Trimester?

You may be surprised by how little additional weight is usually needed early in pregnancy.

According to the American College of Obstetricians and Gynecologists (ACOG), during the first 12 weeks of pregnancy, you may gain only about 1 to 5 pounds—or no weight at all.

Nausea, morning sickness and changes in appetite can also affect your weight during the first trimester.

Generally, you don’t need to add extra calories to your diet during the first trimester simply because you’re pregnant. The focus should be on nutritious foods that give you and your developing baby the nutrients you need.

How Much Weight Should You Gain in the Second and Third Trimesters?

Weight gain typically becomes more consistent as pregnancy progresses.

For someone who began pregnancy at a normal BMI, ACOG says weight gain during the second and third trimesters is generally around one-half to one pound per week.

The recommended rate can be lower for women who began pregnancy overweight or obese and somewhat higher for women who began pregnancy underweight.

Your calorie needs also increase gradually. The CDC recommends approximately:

• • First trimester: Usually no additional calories per day

• • Second trimester: About 340 additional calories per day

• • Third trimester: About 450 additional calories per day

That doesn’t mean you need to “eat for two.” An extra 340 calories might be a nutritious snack or small meal rather than doubling the amount of food you normally eat.

Where Does Pregnancy Weight Go?

Not all pregnancy weight is body fat. Your body is doing an extraordinary amount of work to support your growing baby.

Pregnancy weight includes your baby, placenta, amniotic fluid, increased blood and fluid volume, growing uterus and breasts, and energy stores your body may use during pregnancy and breastfeeding.

That’s another reason to think about pregnancy weight as part of your overall health rather than focusing too closely on the number on the scale.

What If I’m Gaining Too Much—or Too Little?

Don’t panic because of a single weigh-in.

Weight gain doesn’t always happen at a perfectly steady rate. What matters more is the pattern over time, your health and whether your baby is growing appropriately.

ACOG recommends that weight be monitored during prenatal visits. If you’re gaining less than recommended but your baby is growing normally, your healthcare provider may not necessarily recommend trying to “catch up” simply to reach a particular number.

On the other hand, gaining substantially more or less than expected is something to discuss with your OB/GYN, midwife or other prenatal healthcare provider.

Your provider may look at your diet, activity, medications, health conditions and baby’s growth before recommending changes.

Healthy Ways to Manage Pregnancy Weight Gain

Instead of concentrating on dieting or restricting calories during pregnancy, focus on habits that support both you and your baby.

Choose a variety of fruits, vegetables, whole grains, lean proteins and dairy or other calcium-rich foods. Drink plenty of water and stay physically active if your healthcare provider says exercise is appropriate for you.

Regular prenatal appointments are equally important. They allow your provider to monitor your weight, blood pressure, baby’s growth and other signs of a healthy pregnancy.
