Losing weight during pregnancy: Is it safe?

What causes weight gain during pregnancy?
Weight gain during pregnancy occurs due to the development and enlargement of the fetus, placenta, and amniotic sac over the course of the trimesters. Additional weight also comes from increased blood volume, breast tissue, and maternal fat stores.
Why might someone not gain healthy weight?
Weight gain is typically expected in the second and third trimesters. Poor weight gain may result from several factors, including severe nausea and vomiting, known as hyperemesis gravidarum. This condition can cause significant weight loss and dehydration, which may be harmful to both the mother and the baby.
Losing weight during pregnancy: What is a healthy weight during pregnancy?
A healthy pregnancy weight is determined by pre-pregnancy Body Mass Index (BMI). BMI is calculated by dividing weight in kilograms by height squared (m²). Each BMI category has a recommended range of weight gain during pregnancy.

What should a weekly meal plan look like to maintain a healthy weight?
Meal plans vary based on pre-pregnancy BMI and medical conditions. In general:
- First trimester: Maintain usual meal portions
- Second trimester: Increase intake by 350 kcal/day
- Third trimester: Increase intake by 450 kcal/day
A balanced diet should include carbohydrates, proteins, fiber, and essential supplements such as folic acid and calcium.
How many calories should be consumed per trimester?
- First trimester: Maintain usual intake
- Second trimester: Increase by 350 kcal/day
- Third trimester: Increase by 450 kcal/day
These increases support healthy fetal growth and energy needs.
Losing weight during pregnancy: Are weight fluctuations harmful?
Weight gain during pregnancy is normal, and the amount varies based on pre-pregnancy BMI. However, significant or rapid weight loss during pregnancy is not recommended. In such cases, consult your healthcare provider for evaluation and guidance.
What foods help underweight mothers gain weight?
Mothers who are underweight at 20 weeks should seek medical advice to ensure a healthy pregnancy. A well-balanced diet rich in proteins, healthy fats, and essential vitamins can help promote healthy weight gain.
Am I gaining too much weight? How can I slow it down?
For a pre-pregnancy BMI of less than 18, a weight gain of up to 18 kg may be considered normal. Monitoring caloric intake and ensuring a balanced diet with fruits, vegetables, moderate protein, and carbohydrates can help manage excessive weight gain.
How to maintain a healthy BMI while managing gestational diabetes?
Gestational diabetes requires close monitoring of glucose levels. A dietitian can help design a meal plan with controlled carbohydrate intake and calorie counting to manage both weight and blood sugar levels effectively.
Is it normal to gain weight rapidly in the second trimester?
Weight gain varies based on BMI. For those with a BMI between 18–24.9 kg/m², a total gain of 12–16 kg is considered normal throughout pregnancy. The second trimester is typically when more noticeable weight gain begins.
What if I feel the need to eat frequently?
Eating frequent small meals can help manage nausea and support steady energy levels. A balanced diet with carbohydrates, proteins, fiber, and adequate water intake is recommended to meet nutritional needs.

When should I be concerned about losing weight during pregnancy
Experiencing extreme vomiting, diarrhea, and an inability to keep food down can lead to severe weight loss during pregnancy and dehydration. If you face these symptoms, seek medical attention immediately to avoid complications.
How much weight gain is healthy for overweight mothers?
For a pre-pregnancy BMI of 29, a weight gain of 7–11 kg is generally considered healthy. Reducing sugary foods and focusing on nutrient-dense meals with protein, fruits, and vegetables can help maintain balanced weight during pregnancy.
Final thoughts
Maintaining a healthy weight during pregnancy is essential for both mother and baby. While weight gain is a natural part of pregnancy, drastic fluctuations—whether loss or excessive gain—should be discussed with a healthcare provider. A well-balanced diet, proper meal planning, and regular medical guidance ensure a safe and healthy pregnancy journey.
