Default Is Low Carb Safe during Pregnancy?

Quote:
When Carolina Cartier discovered she was pregnant with twins this past March, she never questioned whether she would continue eating a ketogenic diet. The 31-year-old Seattle area woman had been plagued by metabolic issues literally all her life: precocious puberty at age 3; polycystic ovarian syndrome (PCOS) by age 14; weight gain of 320 lbs (145 kg) on her 6 foot (183 cm) frame and pre-diabetes by her 20s.

Her PCOS caused her ovaries to be enlarged and covered in cysts. She was told she was infertile and likely never able to have children.

In August 2014, aged 28, her health was so poor that she went on medical disability from her job as a financial analyst. That first month off, however, she discovered and adopted the ketogenic diet. Between summer 2014 and February 2017, she lost 120 lbs (54 kg), experienced her first ever natural menstrual period that gradually established into a regular 28-day cycle; her blood sugar normalized and her ovaries reduced to 3.5 cm (< 1.5 inches) size. Her long-standing depression lifted.While she lost two early pregnancies at the start of 2016, likely because of poor egg quality, she knew she was getting healthier every day. Her positive pregnancy test in March 2017 was a happy surprise, as was the news soon after that she was carrying healthy twins.


Cartier went from ‘infertile’ and obese, to healthily pregnant
Except for a bout of extreme nausea and sea sickness for a week on a low-carb cruise early in this pregnancy, she has adhered to the ketogenic diet now through to 20 weeks of pregnancy and counting. She plans to continue this way of eating for the rest of her life. She feels great and looks wonderful; the twins in utero are thriving. “My life is transformed. Why would I even consider abandoning this way of eating when all of my positive health changes, and my pregnancy, I owe to this diet?”

The controversy of keto pregnancies

Perhaps no issue in low-carb ketogenic eating is as heated and as controversial as the ketogenic diet during pregnancy. Ketones in the urine of pregnant women scare many good doctors into fearing the life-threatening conditions of diabetic ketoacidosis in pregnancy or starvation ketosis.1 The number of primary care and ob/gyn physicians who understand and are comfortable with nutritional ketosis in pregnancy, while growing, is still exceedingly small.

Since few studies, of any sort, enroll pregnant women because of liability, ethical concerns and the physiologic complexity of pregnancy, evidence-based medicine about what is best for pregnant moms is severely lacking.2
It is known, however, from an increasing number of long-term observational studies, that the unique physiologic conditions and complications of pregnancy predict future disease risk for both mothers and their offspring.3 We know, therefore, that fostering a healthy pregnancy is paramount for mom and babe. But what is the optimal diet for each individual woman and her unborn child?

Into this research vacuum, many doctors default to the oft recommended advice: “Eat low fat with plenty of fruit, vegetables and healthy grains.”4 Some even become apoplectic if a pregnant mom says she is eating low carb or keto. “You are harming your baby!,” some have been told, with doctors often citing research — in mice — that a ketogenic diet exposure in utero led to smaller brain development “associated organ dysfunction” and neurobehavioural changes when they become adult mice.5
But we are not mice, so what is a health-conscious, responsible, expectant mom to do? As there are still no rigorous scientific studies in humans available, it may help to hear the wisdom of experts and individuals who are gaining increasing experience with low-carb ketogenic pregnancies and who are totally comfortable recommending it.

The case for a ketogenic diet

“It is completely safe for women to be eating a ketogenic diet in pregnancy. Women in ancient times were certainly ketotic during pregnancy,” says Dr. Michael Fox, fertility specialist at the Jacksonville Center for Reproductive Medicine, who has not only been recommending a low-carb ketogenic diet for 17 years to his infertile patients but also to all his patients who become pregnant. He has now had hundreds of patients “who have been completely ketotic throughout pregnancy without any untoward effects.”

He recommends women start the diet two to three months before trying to conceive so that the mom is fat adapted before entering pregnancy. He advises that, once pregnant, the mother enjoy frequent low-carb, high-fat eating every two hours from the time she wakes up — with no fasting. His provides a dietary handout of meal and snacking foods that lists items such as cream cheese or unsweetened nut butters on vegetables like celery, cucumber or cauliflower, as well as nuts, egg in all forms, meats, canned and fresh fish, cheeses, avocado, unflavoured pork rinds, butter, full-fat cream.

In his experience eating this way decreases the rates of miscarriage, preeclampsia, gestational diabetes and morning sickness. “Nausea is a reactive hypoglycemic reaction to the dramatically increased insulin resistance caused by pregnancy hormones,” he said.

In one very dramatic case, Dr. Fox had a patient referred to him who previously had such severe hyperemesis gravidarium — extreme vomiting in pregnancy — that it had led to multiple hospitalizations and six previous pregnancy terminations. On his advice she started the ketogenic diet prior to her seventh conception and “she had no nausea during pregnancy and made it all the way to term. This dramatic success demonstrates clearly that the hypoglycemia associated by insulin resistance is immediately relieved by the diet.”

Dr. Robert Kiltz, a fertility specialist at CNY Fertility, with clinics in New York State and Florida, has been recommending the ketogenic diet for improved fertility and pregnancy for the last five years.6 “I like to say that ‘ketogenic’ means ‘the key to genius’!,” says Dr. Kiltz who posts inspirational, pithy videos on Facebook in part to support and encourage women to eat low-carb high-fat foods for conception and pregnancy. “We have zero need for carbohydrates as humans.” Despite now witnessing many successful keto pregnancies, he says he is still in the minority of fertility doctors who recommend this approach.

Ketogenic expert, author, and Diet Doctor contributor Maria Emmerich, who has the popular ketogenic website Mind Body Health, has counselled hundreds of women on ketogenic eating during pregnancy, with great results. “As if this diet of real food would be harmful to the fetus?” she asks rhetorically. She points to evidence that the fetus is naturally in a frequent state of ketosis7 and that it is essential for laying down fatty structures like brains and nerve cells.

Another expert in low carb or ketogenic diets in pregnancy is US dietitian Lily Nichols, whose popular 2015 book Real Food For Gestational Diabetes has a whole chapter on the benefits of ketosis. She has helped hundreds of pregnant women in her career as specialist in gestational diabetes (GD), also known as “carbohydrate intolerance of pregnancy.” Along with her book and website, she frequently blogs and appears as an expert guest on low-carb keto podcasts. GD is such an important issue in pregnancy, particularly for women who may have undiagnosed pre-diabetes prior to conception, that part two of this post focuses solely on that condition, and what to eat for it, featuring an in depth interview with Nichols.

“I find it ironic that if you tell your doctor that you plan to eat low carb during pregnancy, they’ll say it is unsafe, but if you say you to plan to eat a diet based on fresh vegetables, meat, fish, eggs, dairy, nuts, seeds and a little fruit, they will tell you to stay the course,” she says.

She also notes, however, that some women especially during early days of pregnancy feel better eating slightly more carbs. If that happens “don’t beat yourself up, go for it. You have to get through the first trimester anyway you can.” But try, she says, to always opt for nutrient-dense food. “All pregnant women benefit from the most nutrient dense diet they can manage and that just happens to be naturally lower in carbohydrates.”

Real keto moms

For some moms like Jill Kingsley, who has experienced two high-carb pregnancies and a third ketogenic pregnancy, the advantage of the latter was exceedingly clear. She decided to switch to a ketogenic diet 16 weeks into her third pregnancy this past year after experiencing extreme nausea. Within 24 hours of switching, her nausea resolved.

“It was obvious, my body runs better on fat and protein. I can’t do carbs,” said the 32-year-old Mesa Arizona mom. Her two previous pregnancies had been wrought with issues: swelling and bloating, high blood pressure, extreme nausea, and infections. She had complete bed rest for her entire second pregnancy because her nausea was so bad she couldn’t stand up.

In her keto pregnancy her blood pressure was normal and her weight gain moderate, she experienced no swelling or bloating, and she felt great. She marvels at the fact that during her keto pregnancy she was going for long walks with no difficulty right up until labour, when during her second carb-fueled pregnancy “I couldn’t even get out of bed.”

She gave birth to 6 lb 9 ounce (3 kg) Justin Tyler Kingsley on July 11 after 3 hours and 2 minutes of labour, from the time her water broke to delivery. “He is my perfect keto baby.” Her midwife, who had never attended to a keto mom in more than 300 births, was at first a bit skeptical and then amazed at the results. She told Jill that with her keto eating “You took your pregnancy from high risk to low risk for both you and your baby.”

For Carolina Cartier, it frustrates and even angers her that anyone would suggest, with her health history, that she add carbs back in during pregnancy for her twins and that she must eat a daily carb requirement. She firmly believes it was her mother’s high-carb eating and poorly controlled gestational diabetes, exposing her to high blood sugars and high levels of insulin in utero, that set her up for her metabolic issues. “The ketogenic diet was such a simple fix to all my problems. Had anyone ever said ‘Don’t eat sugar or foods that convert to sugar’ I could have avoided two decades of pain.”

So not only is Carolina firmly staying keto through her pregnancy, she has enrolled to retrain as a nutritionist at a Bastyr University in Washington State for Fall 2018, after her maternity leave. “I want to support and empower other people, particularly pregnant moms, in this diet.” In fact, she is already a frequent commentator helping other would-be moms learn about ketogenic eating on two closed Facebook groups8 devoted to ketogenic pregnancies. Each already has around 5,000 members, and growing.

In some recent advice to other members about what to tell your doctor about how you have chosen to eat for your baby, she counselled: “Don’t say keto. It makes them scared. Say you’re eliminating sugar and processed, starchy foods. No doctor is going to give you a daily sugar requirement.”
