What is the Ideal Pregnancy Weight Gain by Week?
The recommended weight gain during pregnancy varies depending on a woman’s pre-pregnancy weight. According to the Institute of Medicine (IOM), women who are underweight should gain between 28-40 pounds, while women who are overweight should gain between 15-25 pounds. For women of average weight, the recommended weight gain is between 25-35 pounds.

Pain Points
- Excessive weight gain: Gaining too much weight during pregnancy can increase the risk of complications such as gestational diabetes, preeclampsia, and macrosomia (a large baby).
- Insufficient weight gain: Not gaining enough weight during pregnancy can affect fetal growth and development.
Motivations
- Healthy pregnancy: Maintaining a healthy weight during pregnancy is essential for the well-being of both the mother and the baby.
- Easier labor and delivery: Women who gain within the recommended weight range tend to have shorter labor times and fewer complications during delivery.
- Faster postpartum recovery: Women who maintain a healthy weight during pregnancy are more likely to recover more quickly after childbirth.
Tips and Tricks for Healthy Pregnancy Weight Gain
- Follow a balanced diet: Eat a variety of healthy foods from all food groups.
- Listen to your body’s hunger cues: Eat when you’re hungry and stop when you’re full.
- Avoid processed foods, sugary drinks, and unhealthy fats: These foods are high in calories and provide little nutritional value.
- Stay hydrated: Drink plenty of water throughout the day.
- Get regular exercise: Aim for at least 150 minutes of moderate-intensity exercise per week.
- Talk to your healthcare provider: Discuss your weight gain goals and any concerns you have with your doctor or midwife.
How to Calculate Your Pregnancy Weight Gain
To calculate your pregnancy weight gain, use the following formula:
Pre-pregnancy weight (kg) x weight gain recommendation (%) = Target weight gain (kg)
For example, if you weigh 55 kg before pregnancy and are of average weight, your target weight gain would be:
55 kg x 25% = 13.75 kg
