Pregnancy Weight Gain Breakdown by Week
Gaining a healthy weight during pregnancy isn’t rocket science! Trust your body’s wisdom, stay active, and nourish yourself well. Don’t fixate on sweets; opt for veggies and nuts instead. Understand that every pregnancy journey is unique, so avoid comparing your growth rate to others.
However, one aspect demands attention: an extremely rapid weight gain exceeding 0.5 kg (1.1 lb) per week. Monitor your weight closely, and consult your healthcare provider if you’re packing on pounds at an alarmingly fast pace.
Here are the estimated growth rates for an average singleton pregnancy. Remember: they’re not one-size-fits-all!
- <14 weeks — your weight shouldn’t fluctuate much during the first trimester.
- 14–20 weeks — a steady gain kicks in, totaling around 2.5 kg.
- 20–30 weeks — another 5 kg increase.
- 30–36 weeks — an additional 2.5 kg.
- 36–40 weeks — no further weight gain is expected by the third trimester’s end.
One study broke it down into finer details:
- 0 to 10 weeks — 0.065 kg, 2.3 oz, or 0.14 pounds weekly.
- 10 to 20 weeks — 0.335 kg or 0.74 lb per week.
- 20 to 30 weeks — 0.450 kg or 1 lb weekly.
- 30 to 40 weeks — 0.335 kg or 0.74 lb per week.
How Much Weight Should I Gain?
Your pre-pregnancy body mass index (BMI) determines your recommended weight gain range. BMI provides a simple way to assess someone’s weight relative to their height and compare it to population averages. However, BMI guidelines don’t directly apply to pregnant women! That’s why we record the woman’s pre-pregnancy weight and monitor her weekly growth rate (see: our gestational age calculator).
The BMI formula is:
BMI=weight [kg](height [m])2BMI=(height [m])2weight [kg]
Your recommended gain depends on your pre-pregnancy BMI:
- Underweight (BMI <18.5)
- Expected gain: 28–40 pounds (12.7–18.1 kg)
- Normal weight (BMI 18.5–24.9)
- Single pregnancy: 25-35 pounds (11.3–15.9 kg)
- Twins: 37–54 pounds (16.8–24.5 kg)
- Overweight (BMI 25-29.9)
- Single pregnancy: 15–25 pounds (6.8–11.3 kg)
- Twins: 31–50 pounds (14–22.7 kg)
- Obese (BMI over 30)
- Single pregnancy: 11–20 pounds (5–9 kg)
- Twins: 25–42 pounds (11.3–19 kg)
Where Does the Extra Weight Go?
Contrary to the old adage, eating for two isn’t really advisable. Your dietary intake should increase by only 300 kcal in the second trimester and up to 500 kcal when breastfeeding. 🍼
As you might expect, the weight gained serves vital purposes. You’re not just eating for yourself: that mass supports the baby’s growth and a healthy gestation. For a typical pregnancy, an average gain of 25–35 pounds (11.3–15.9 kg) is recommended.
Let’s break it down:
- The baby: Around 7.7 lb (3.5 kg) birth weight.
- An enlarged uterus weighs ~2 lb (0.9 kg).
- Enlarged breasts add ~2 lb (0.9 kg).
- The placenta contributes 1.5 lb (0.7 kg).
- Amniotic fluid accounts for ~2 lb (0.9 kg).
- Your increased blood volume (~50%) and fluids: 6.6 lb (3 kg).
- Extra fat stores: ~7.7 lb (3.5 kg).
Expecting a baby is one of life’s most beautiful and transformative journeys. As your body undergoes remarkable changes, maintaining a healthy weight gain during pregnancy becomes essential for both you and your growing little one. That’s where a pregnancy weight gain calculator comes in handy, providing guidance and empowering you to navigate this incredible experience with confidence.
Why Track Pregnancy Weight Gain?
Monitoring your weight gain during pregnancy may seem like a simple task, but it carries significant benefits that can positively impact your overall well-being and the health of your baby. Here are a few compelling reasons why tracking your pregnancy weight gain is crucial:
- Ensuring Proper Fetal Development: Gaining an appropriate amount of weight helps provide the necessary nutrients for your baby’s growth and development. Insufficient weight gain can potentially lead to complications such as premature birth or low birth weight, while excessive weight gain may increase the risk of gestational diabetes and other issues.
- Reducing Complications: By staying within the recommended weight gain ranges, you can lower the risks of pregnancy-related complications like preeclampsia, gestational diabetes, and delivery complications. Maintaining a healthy weight can also contribute to a smoother postpartum recovery.
- Promoting Overall Well-being: Keeping track of your weight gain allows you to make informed decisions about your diet and physical activity levels. This holistic approach can help you feel more energized, minimize discomfort, and enhance your overall well-being during this transformative phase.
Next Step: Start tracking your weight gain from the beginning of your pregnancy. Consult with your healthcare provider to establish a personalized target range based on your pre-pregnancy body mass index (BMI) and other factors.
Factors Influencing Pregnancy Weight Gain
While weight gain during pregnancy is natural and necessary, the recommended ranges can vary depending on several factors. Understanding these elements will help you set realistic and tailored goals for a healthy pregnancy journey:
- Pre-pregnancy BMI: Your pre-pregnancy body mass index (BMI) is a crucial factor in determining the recommended weight gain range. Women who start their pregnancy underweight, overweight, or obese may have different target ranges compared to those with a normal pre-pregnancy BMI.
- Age: Younger women (under 20 years old) and older women (over 35 years old) may have slightly different weight gain recommendations due to varying nutritional needs and potential risks.
- Height: A woman’s height can influence the recommended weight gain range, as taller individuals may require more weight gain to support the growing baby’s needs.
- Number of Babies: Carrying twins, triplets, or more babies will require a higher weight gain compared to a single pregnancy to ensure adequate growth and development for each baby.
- Previous Pregnancies: If you’ve had previous pregnancies, your healthcare provider may adjust the recommended weight gain range based on your experiences and any complications you may have faced.
Next Step: Discuss your specific circumstances with your healthcare provider to determine the most appropriate weight gain range for your pregnancy.

Understanding the Recommended Weight Gain Ranges
The recommended weight gain ranges during pregnancy are based on your pre-pregnancy BMI, which is calculated using your height and weight. Here’s a breakdown of the generally accepted guidelines:
- Underweight (BMI < 18.5): If you were underweight before pregnancy, the recommended weight gain range is 28-40 pounds (12.7-18.1 kg). This higher range helps ensure that both you and your baby receive adequate nutrients for healthy growth and development.
- Normal Weight (BMI 18.5-24.9): For women with a normal pre-pregnancy BMI, the recommended weight gain range is 25-35 pounds (11.3-15.9 kg) for a single pregnancy and 37-54 pounds (16.8-24.5 kg) for carrying twins.
- Overweight (BMI 25-29.9): If you were overweight before pregnancy, the recommended weight gain range is 15-25 pounds (6.8-11.3 kg) for a single pregnancy and 31-50 pounds (14-22.7 kg) for twins.
- Obese (BMI ≥ 30): For women with obesity, the recommended weight gain range is 11-20 pounds (5-9 kg) for a single pregnancy and 25-42 pounds (11.3-19 kg) for twins.
It’s important to note that these ranges are general guidelines, and your healthcare provider may adjust them based on your individual circumstances, such as age, ethnicity, or any underlying health conditions.
Next Step: Discuss your pre-pregnancy BMI and the recommended weight gain range with your healthcare provider to ensure that you’re on the right track for a healthy pregnancy.
| Pre-Pregnancy BMI | BMI Range | Recommended Weight Gain |

Healthy Eating and Exercise During Pregnancy
While tracking your weight gain is crucial, maintaining a balanced diet and incorporating appropriate exercise can significantly contribute to a healthy pregnancy. Here are some tips to help you nourish your body and stay active during this special time:
- Balanced Nutrition: Focus on consuming a variety of nutrient-dense foods from all food groups, including fruits, vegetables, whole grains, lean proteins, and healthy fats. Aim for a diet rich in vitamins, minerals, and fiber to support your baby’s growth and development.
- Portion Control: While you may need to increase your calorie intake during pregnancy, it’s essential to practice portion control. Overeating can lead to excessive weight gain, which can increase the risk of complications. Consider using a pregnancy weight gain calculator to help you determine appropriate calorie needs.
- Stay Hydrated: Drinking plenty of water and incorporating fluids like milk, unsweetened juices, and herbal teas can help support your increased blood volume and prevent dehydration during pregnancy.
- Safe Exercise: Regular exercise can help you manage your weight gain, reduce pregnancy-related discomforts, and prepare your body for labor and delivery. However, it’s crucial to consult your healthcare provider to determine the most suitable exercises and intensity levels for your specific pregnancy.
- Listen to Your Body: Every pregnancy is unique, and it’s essential to tune in to your body’s signals. If you feel fatigued or experience any discomfort, don’t hesitate to adjust your routine or seek guidance from your healthcare provider.
Next Step: Create a meal plan that incorporates a variety of nutritious foods and plan for regular physical activity that suits your current fitness level and pregnancy stage.
| Trimester | Additional Calories Needed |
|---|---|
| First | No extra calories |
| Second | +340 calories/day |
| Third | +450 calories/day |
Addressing Concerns and Complications
While weight gain is a natural and expected part of pregnancy, there may be instances where you experience concerns or complications. Being aware of these potential issues can help you address them promptly and ensure the best possible outcome for you and your baby.
- Excessive Weight Gain: If you’re gaining weight more rapidly than recommended, it’s essential to address this promptly. Excessive weight gain can increase the risk of gestational diabetes, preeclampsia, and other complications. Your healthcare provider may suggest adjustments to your diet and exercise routine to help manage your weight gain.
- Insufficient Weight Gain: On the other hand, if you’re not gaining enough weight, it could indicate that your baby is not receiving adequate nutrients for proper growth and development. Your healthcare provider may recommend dietary changes or supplementation to help you meet your weight gain goals.
- Gestational Diabetes: Some women may develop gestational diabetes during pregnancy, which can impact weight gain and overall health. If you’re diagnosed with gestational diabetes, your healthcare provider will provide guidance on managing your blood sugar levels through diet, exercise, and possibly medication.
- Preeclampsia: Preeclampsia is a condition characterized by high blood pressure and protein in the urine. It can be associated with excessive weight gain and can potentially lead to serious complications if left untreated. Regular prenatal checkups and monitoring are crucial for early detection and management.
- Mental Health Concerns: Pregnancy can bring about emotional changes and body image concerns. If you’re struggling with anxiety, depression, or disordered eating patterns, it’s essential to seek support from your healthcare provider or a mental health professional.
Next Step: Don’t hesitate to discuss any concerns or complications with your healthcare provider. Early intervention and appropriate management can help ensure a healthy pregnancy and a positive outcome for both you and your baby.
Postpartum Weight Management
While the focus during pregnancy is on healthy weight gain, postpartum weight management is equally important for your long-term well-being. Here are some tips to help you navigate this transition:
- Be Patient: It’s normal for it to take time to lose the weight gained during pregnancy. Aim for a gradual and sustainable approach to postpartum weight loss, rather than engaging in extreme diets or rapid weight loss programs.
- Breastfeeding Benefits: If you choose to breastfeed, it can help burn additional calories and support postpartum weight loss. However, it’s essential to maintain a balanced diet and stay well-hydrated to ensure an adequate milk supply.
- Incorporate Exercise: As your body recovers from childbirth, gradually incorporate gentle exercise routines, such as walking, yoga, or postpartum-specific workouts. Always consult your healthcare provider before starting any new exercise regimen.
- Seek Support: Postpartum weight management can be challenging, both physically and emotionally. Don’t hesitate to reach out to your healthcare provider, a registered dietitian, or join support groups for new mothers to receive guidance and encouragement.
- Celebrate Your Journey: Remember that your body has gone through an incredible transformation, and it may take time to return to your pre-pregnancy weight or shape. Embrace the changes, celebrate your strength, and focus on nurturing yourself and your new baby.
Next Step: Discuss postpartum weight management strategies with your healthcare provider and create a plan that aligns with your goals and lifestyle.
Emotional Well-being and Body Positivity
Pregnancy is a beautiful and transformative journey, but it can also bring about emotional challenges and body image concerns. It’s essential to prioritize your emotional well-being and cultivate a positive mindset throughout this experience.
- Embrace Your Changing Body: Your body is undergoing remarkable changes to accommodate the growth of your baby. Celebrate these changes and appreciate the incredible feat your body is accomplishing.
- Practice Self-Care: Engage in activities that nourish your mind, body, and soul. Whether it’s relaxing with a warm bath, practicing mindfulness, or indulging in a hobby you enjoy, make time for self-care.
- Seek Support: Surround yourself with a supportive network of loved ones, and fellow expectant mothers, or join online communities where you can share your experiences and concerns without judgment.
- Challenge Negative Thoughts: If you find yourself caught up in negative self-talk or unrealistic expectations about your body, challenge those thoughts and replace them with positive affirmations.
- Focus on the Journey: Remember that pregnancy is a temporary state, and your body will continue to change and adapt throughout this journey and beyond. Embrace the present moment and cherish the incredible experience of bringing new life into the world.
Next Step: Identify healthy coping mechanisms and self-care practices that resonate with you, and make them a priority during your pregnancy journey.
