If you’re concerned about how much weight you should gain, speaking to your gynecologist can provide clarity and reassurance. They can help you create a personalized pregnancy weight gain chart by week in kg, ensuring you feel confident and in control. Embrace this journey with kindness towards yourself, knowing that these changes are a natural part of bringing new life into the world. So, read on to understand the essentials of weight gain in pregnancy and ensure a healthier journey for you and your child.
Understanding Weight Gain in Pregnancy
Too much or too little weight gain during pregnancy can have serious implications for both you and your baby. Excessive weight gain can negatively impact your health, leading to conditions like high blood pressure and increasing the risk of complications. For instance, gestational diabetes, caused by elevated blood sugar levels during pregnancy, can result in a larger baby, while high blood pressure can be an early indicator of pre-eclampsia. Although many cases of pre-eclampsia are mild, it can sometimes become severe and require immediate attention.
On the other hand, insufficient weight gain in pregnancy can lead to problems like premature birth or a baby with low birth weight, defined as less than 2.5 kilograms (5.5 pounds) at birth. It can also mean your body isn’t storing enough fat, which is essential for energy and breastfeeding. Maintaining a healthy weight gain during pregnancy is essential to support your health and your baby’s development.
Pregnancy Weight Gain Chart
To ensure your and your baby’s well-being, maintaining a healthy weight gain during pregnancy is crucial. However, the ideal weight gain depends on your pre-pregnancy body mass index (BMI) and weight.
Pregnancy weight gain chart by week in kg
When it comes to the typical pregnancy weight gain chart by week in kg, most women gain 1 to 2 kilograms (2 to 4 pounds) during the first trimester, and then 0.5 kilogram (1 pound) a week for the rest of the pregnancy. Consider this general pregnancy weight gain chart to determine what’s best for you:
| Pre-pregnancy Weight | Healthy Weight Gain During Pregnancy |
| Underweight (BMI under 18.5) | About 13 to 18 kg (28 to 40 lbs) |
| Healthy weight (BMI between 18.5 and 24.9) | About 11 to 16 kg (25 to 35 lbs) |
| Overweight (BMI between 25 and 29.9) | About 7 to 11 kg (15 to 25 lbs) |
| Obese (BMI of 30 or higher) | About 5 to 9 kg (11 to 20 lbs) |
Factors That Affect Weight Gain in Pregnancy
Weight gain during pregnancy can vary significantly based on several factors, including:
- Body Mass Index (BMI) before pregnancy
- Pre-pregnancy weight
- The overall health and development of the foetus
- Whether the pregnancy involves twins or multiples
- The trimester of pregnancy
While the baby itself typically accounts for around 7–8 lbs of the weight gained, much of the additional weight is attributed to pregnancy-related changes rather than fat accumulation. For individuals with a moderate BMI (between 18.5 and 24.9), the suggested weight gain during pregnancy is approximately 25–35 lbs. This is generally distributed as follows:
- Baby: 7–8 pounds
- Amniotic fluid: 2–3 pounds
- Placenta: 2–3 pounds
- Breast tissue: 2–3 pounds
- Uterus: 2–5 pounds
- Increased blood volume: 4 pounds
- Fat reserves for labour and breastfeeding: 5–9 pounds
This general pregnancy weight gain chart highlights how the increased weight supports both the baby’s growth and the mother’s preparation for childbirth and breastfeeding.

Exercise During Pregnancy
Regular physical activity is generally considered safe and beneficial during pregnancy unless a healthcare professional advises otherwise. It not only helps prepare your body for labour and delivery but also aids in keeping weight gain during pregnancy under control. Moderate exercise, tailored to your stage of pregnancy and approved by your healthcare provider, can help burn extra calories and maintain fitness levels. Aiming for about 30 minutes of moderate exercise daily is ideal, which can also be broken into three 10-minute sessions.
Pregnancy-friendly exercises include walking, aqua aerobics, swimming, and prenatal exercise classes. These activities can help prevent excessive weight gain, lower the risk of gestational diabetes, improve physical fitness to better handle labour, and establish habits that make post-pregnancy weight loss easier. However, certain activities should be avoided during pregnancy, such as those involving heavy weightlifting or exercises that can excessively raise your body temperature. Always consult your doctor before starting or modifying an exercise routine to ensure it is safe for you and your baby.
Diet Chart to Increase Weight in Pregnancy
Contrary to popular belief, you don’t need to eat for two to increase weight in pregnancy. When it comes to the ideal diet for the first trimester, your caloric needs typically remain the same, with an increase becoming necessary in the second and third trimesters. In most cases, the ideal amount of calories required is:
- 1,800 calories/day in the first trimester
- 2,200 calories/day in the second trimester
- 2,400 calories/day in the third trimester
Since larger meals may feel uncomfortable, you can meet your energy requirements by incorporating healthy snacks throughout the day. A balanced, nutritious diet is key to gaining the right amount of weight during pregnancy. Ensure your meals include the five essential food groups:
- Vegetables
- Fruits
- Wholegrain breads and cereals
- Legumes, fish, and lean meats
- Dairy products
Additionally, focus on consuming key nutrients like iron, calcium, folic acid, and iodine, as they are vital for your health and your baby’s development. Limit fast food and sugary drinks, as they provide minimal nutritional value. It’s also crucial to stay hydrated by drinking approximately 2.3 litres of water daily. Be sure to familiarise yourself with foods that are safe to consume during pregnancy to ensure a healthy diet.
Conclusion
Maintaining a healthy weight gain in pregnancy is vital for the well-being of both the mother and the baby. By following a balanced diet, staying hydrated, and incorporating regular, moderate exercise, you can manage your weight effectively throughout this journey. It’s equally important to tailor your weight gain goals according to your pre-pregnancy BMI, with the help of a pregnancy weight gain chart. This not only ensures optimal health during pregnancy but also helps prepare your body for childbirth and postpartum recovery.
