Is Intermittent Fasting While Pregnant a Bad Idea?

When a woman is pregnant, she is eating for two. Not only does she need to consume enough calories to maintain her own health, but she also needs to provide nourishment for her growing baby. For many women, this means increasing their calorie intake by 300-500 calories per day. However, some women choose to follow a diet known as intermittent fasting (IF) during pregnancy.

What is intermittent fasting and how does it work

Intermittent fasting is an umbrella term for various diets that cycle between periods of fasting and eating. The most common method is the 16/8 method, which involves fasting for 16 hours each day and consuming all calories within an 8-hour window. Other methods involve fasting for 24 hours once or twice per week.

During pregnancy, a woman’s body undergoes many changes. Her metabolism changes to support the growing baby, and her hormone levels also fluctuate. These changes can make it more difficult for pregnant women to fast safely.

How to do intermittent fasting while pregnant

If you’re pregnant and considering intermittent fasting, it’s important to speak with your healthcare provider first. They can help you determine if intermittent fasting is right for you and your pregnancy.

If your healthcare provider gives you the green light to try intermittent fasting, there are a few things to keep in mind:

  • Drink plenty of water: Staying hydrated is crucial for both you and your baby. When fasting, be sure to drink eight glasses of water per day.
  • Eat nutrient-rich foods: When you do eat, be sure to fill up on nutrient-rich foods like fruits, vegetables, lean protein, and whole grains. These foods will help you meet your increased calorie needs and give you the nutrients you and your baby need.
  • Avoid processed foods: During pregnancy, it’s important to limit your intake of processed foods, as they can be high in calories, sugar, and unhealthy fats.
  • Listen to your body: Pregnancy is a time when you should listen to your body. If you’re feeling hungry, eat. Don’t try to push through hunger pains or fatigue.

Intermittent fasting and pregnancy risks

There are a few risks to consider before intermittent fasting while pregnant, such as:

  • Dehydration: When you fast, your body breaks down stored glycogen for energy. This process can lead to dehydration, especially if you’re not drinking enough water. Dehydration can cause complications like dizziness, fatigue, and headaches.
  • Malnutrition: If you’re not eating enough nutrient-rich foods, you and your baby may become malnourished. This can lead to complications like low birth weight and birth defects.
  • Gestational diabetes: Intermittent fasting may increase your risk of gestational diabetes. This is a type of diabetes that only occurs during pregnancy and can cause complications like high blood pressure and preeclampsia.

Alternatives to intermittent fasting during pregnancy

If you’re looking for a way to lose weight during pregnancy, there are other options. First, you can try making small changes to your diet. For example, you can cut out processed foods and eat more fruits, vegetables, and lean protein. You can also try reducing your portion sizes.

Another option is to talk to your doctor about starting a moderate exercise program. Walking, swimming, and prenatal yoga are all great forms of exercise for pregnant women.

Additionally, there are weight loss programs designed specifically for pregnant women. These programs offer support and guidance on how to safely lose weight during pregnancy.

Intermittent fasting is not recommended for pregnant women. If you’re considering this diet, it’s important to speak with your doctor first. They can help you make the best decision for your health and your baby’s health.
