Dear Stephanie, is it safe for me to do a Whole30 during my pregnancy? Will my baby get all the nutrients he/she needs? How do I combat morning sickness without crackers and ginger ale, and there’s no way I’m going to be able to not snack! Help! – Pregnant Women on Facebook, Instagram, Twitter, Periscope and the Internet

Dear Pregnant Women, you are not alone in wondering if a Whole30 is safe to do while pregnant. We (Whole30 co-creator Melissa Hartwig Urban and myself) get questions every day about the safety and feasibility of completing a Whole30 during pregnancy. In fact, this is the primary reason we created the Whole Mamas Pregnancy Program.

Common concerns

Your Whole30-while-pregnant concerns are common. They also show me how serious you are about your health and the health of your baby. As a registered dietitian, I’m happy to say that a Whole30 is perfectly safe for most pregnant women. And as a mom, I can lend you my support and encouragement because I did a Whole30 during my pregnancy. During pregnancy, it’s possible to complete a Whole30 exactly as outlined in The Whole30 program guidelines.  However, I have a few additional recommendations to make those 30 days as smooth and stress-free as possible:

  1. Listen to your body
  2. Make sure you are eating enough
  3. Enjoy smaller meals and snacks, if desired
  4. Consider your protein and carb intake

We hear the following concerns over and over again:

Concern #1: I’m afraid I’ll LOSE too much weight if I do a Whole30.

When you embark on a Whole30, you remove foods (grains, legumes, and dairy) that may be accounting for a large percentage of your total calorie intake. This is especially true if you’re coming to the program from a standard American diet. Now, not only are you potentially eliminating significant sources of calories, but you are replacing those foods with foods that promote satiety (non-starchy vegetables, healthy fat, and protein). This is all happening during a time when your body needs an additional 300-500 calories to promote the health, growth and development of you and your baby. Do you see how this scenario can set us up for potential weight loss or under-consumption of calories?

Eat enough good food

Pregnancy isn’t truly a time to eat for two. Your body does require additional calories, however. You want to make sure these additions come from nutrient-dense sources. Ideally, your meals and snacks should contain plenty of healthy fat, protein, vegetables (starchy and non-starchy) and fruit. If you’re coming to the Whole30 from a low-fat or calorie controlled diet, you may have to make a conscious effort to include enough healthy fat with each meal. You’ll need to make sure you purposefully include enough starchy vegetables (like potatoes and winter squash) and fruit to support your activity level if you are exercising. This will ensure that you are providing yourself with the nutrients and energy required to grow a tiny human.

At any point during your pregnancy, if you’re losing too much weight, or are feeling under-fed and exhausted, it may be time to take a break from your Whole30. Now isn’t the time to “push through it” or “Whole30 harder.” Listen to your body, take a break, and do whatever you need to do to get through the rough time. This may include eating a gluten-free bagel or some full-fat, grass-fed yogurt. As your energy levels increase and you feel better, check in with your healthcare provider, and consider restarting your Whole30 at a later date.

Our Whole Mamas Pregnancy Program  addresses this in depth, and we include sample meal plans to give you plenty of ideas on how to eat well during pregnancy.

Concern #2: There’s no way I can eat that much protein, fat, and non-starchy vegetables at each meal!

While the recommendations of the traditional Whole30 program say to avoid/minimize snacking, you may need to ditch this recommendation during your pregnancy. This is especially true if you are dealing with morning sickness or are in your 3rd trimester. Having smaller meals every three hours may help alleviate some of the nausea you experience. Nausea can be triggered by an empty stomach or low blood sugar. As your baby grows, you may not have the physical space in your stomach to eat larger meals. Do the best you can with the issues that pop up and remember that everything you’re eating is nutrient-dense and healthy for your baby. That’s the most important thing!

In our Whole Mamas Pregnancy Program, we give you meal plans, tips, and tricks designed to help you comfortably modify the Whole30 to account for these exceptions.

Concern #3: Should I modify the recommended portion sizes in the Whole30 Meal Planning Template?

Pregnancy is not the time to follow a very low-carbohydrate or low-fat diet. You’ll want to add some form of starchy vegetables and/or fruit to most of your meals. This will ensure you and your baby receive a wide-variety of nutrients. This will also reduce any additional stress on your body as a result of going too low-carb. You’ll also want to consider aiming for the higher end of the recommendations for fat (two servings per meal) to make sure you’re consuming enough calories since you’re eliminating calories from grains, legumes and dairy.

Protein aversions

Many women experience protein aversions during pregnancy, especially during the first trimester. You may naturally find yourself consuming less throughout the day. If a palm-sized amount of protein at each meal seems impossible, you can try having smaller meals. Use a plain, unsweetened egg-white protein powder or collagen peptides in smoothies.  Try a cup of bone broth mixed with collagen peptides, or whatever you need to do to make it work. Don’t stress about it too much. You’ll likely feel much better once the second trimester hits, and can resume eating your normal protein staples.

No need to limit fruit

You may also choose to ditch the Whole30 recommendation to limit fruit. I found myself craving fruit during my pregnancy and enjoyed it a few times a day. Just make sure to pair fruit and starchy vegetables with protein or fat. This will reduce the impact on your blood sugar levels. The more we can prevent blood sugar spikes and crashes, the better you’ll feel. Bonus, you’ll have lower chances of developing pregnancy-related complications!

Know that Melissa and I would never advocate for doing a Whole30 for your entire pregnancy. In fact, you might not Whole30 at all! You can still focus on the main principles outlined by the program and have a fantastic pregnancy. Lastly, know that there is no such thing as a perfect Whole30 while pregnant. Your version of a a Whole30 may be very different from another pregnant mama’s, and that’s totally fine! The key is finding a balance of nutrient-dense, whole foods that works for your unique needs.
