The ketogenic diet is a popular diet for weight loss and maintenance, but its impact on pregnant women and their unborn babies is not well understood. The diet is high in fat, low in carbohydrates, and can lead to nutritional deficiencies, which may be harmful to the developing fetus. While the ketogenic diet has been shown to have positive effects on fertility in women with Polycystic Ovary Syndrome, there is limited research on its effects during pregnancy, with most studies conducted on animals. Some animal studies suggest that a ketogenic diet during pregnancy may alter organ growth and function and increase the risk of neurobehavioral issues in offspring. However, the applicability of these findings to humans is uncertain, and more research is needed to determine the safety and potential benefits of the ketogenic diet for pregnant women and their unborn babies.

What You'll Learn
Nutritional deficiencies
One of the most important nutrients that can be lacking in a ketogenic diet is folic acid. Folic acid is essential for the development of the baby's brain and spine and is commonly found in carbohydrate-rich foods such as fortified cereals, enriched bread, and beans. Studies have shown that even with folic acid supplementation, women on low-carbohydrate diets may still not meet the required intake of folic acid. This can lead to an increased risk of neural tube defects in the developing fetus.
In addition to folic acid, a ketogenic diet may also result in mineral and vitamin deficiencies. This can include a lack of essential vitamins and minerals such as iron, vitamin B, and choline, which are all crucial for fetal development. Choline, in particular, has been recognised for its importance in the neural and metabolic health of the developing fetus.
Furthermore, the ketogenic diet has been associated with alterations in embryonic organ growth, including the brain, heart, and other vital organs. These alterations may lead to organ dysfunction and potential behavioural changes in postnatal life. While some studies have been conducted on mice and rats, more research is needed to fully understand the impact of a ketogenic diet on human fetal development.
Due to the potential nutritional deficiencies and the critical role of a balanced diet during pregnancy, it is generally recommended that pregnant women avoid restrictive diets such as keto and instead focus on consuming a variety of nutrient-dense foods from all food groups. This includes fruits, vegetables, grains, lean protein, and dairy products to ensure that both the mother and the baby receive adequate nutrition.

Organ development
The ketogenic diet is characterized by a high-fat content and reduced carbohydrate supply. While this diet has proven effective in treating epilepsy, obesity, neurodegenerative diseases, and metabolic disorders, its effects on pregnant women and their unborn children are less clear.
Pregnancy is a unique time when the body undergoes extensive changes, including hormonal shifts and the growth of the placenta and baby. A balanced diet, sufficient in all nutrients, is crucial to support these changes and the appropriate development of the fetus.
Research on the effects of a ketogenic diet during pregnancy on embryonic organ growth is limited. Mouse studies have shown that a ketogenic diet during gestation can result in alterations in embryonic organ growth, with mixed results. Some studies found that mouse embryos exposed to a ketogenic diet in utero had larger hearts but smaller brains, pharynxes, cervical spinal cords, hypothalami, midbrains, and ponses. Other studies found that a ketogenic diet during pregnancy resulted in larger embryo volumes at an early stage of development, but smaller volumes at a later stage, with enlarged cervical spines, thalami, midbrains, and ponses.
While mouse studies provide valuable insights, it is important to recognize that human fetal development differs from mouse fetal development. To date, there is limited research directly investigating the implications of a ketogenic diet on human embryonic organ growth. However, one case series described two pregnant women with epilepsy who used a ketogenic diet to control their seizures. One woman gave birth to a baby with no developmental issues up to 12 months of age, while the other's baby had bilateral ear deformities, though it is unclear if this was caused by the diet or other factors.
In conclusion, while there are limited reports of successful pregnancies while following a ketogenic diet, the potential risks to the developing fetus are unclear. More human studies are needed to determine the safety of a ketogenic diet during pregnancy and its potential impact on embryonic organ growth and development.

Behavioural changes
Some studies on mice and rats have shown that a ketogenic diet during pregnancy may lead to behavioural changes in the offspring. For example, one study found that adult mice exposed to a ketogenic diet in utero exhibited neurobehavioural changes in young adulthood. Another study on Wistar rats found that prenatal exposure to a ketogenic diet may affect the brain biomolecular composition of the offspring, which could potentially lead to behavioural changes.
Additionally, a study on CD-1 mice found that a ketogenic diet during pregnancy resulted in alterations in embryonic organ growth, specifically a smaller brain, which could potentially impact behaviour. These findings suggest that a ketogenic diet during pregnancy could have behavioural consequences for the child, but more research is needed to confirm this.
Furthermore, it is speculated that prolonged ketosis, a metabolic state that burns fat as the primary source of energy, could be concerning for both the mother and the baby. This is because ketosis may affect the brain and nervous system, which are primarily fuelled by carbohydrates.
Overall, while the ketogenic diet may be beneficial for certain medical conditions, its potential impact on behavioural changes in unborn babies needs further investigation. Pregnant women should consult with their doctors before making any significant diet changes to ensure the safety and well-being of themselves and their unborn children.

Epigenetic alterations
A balanced diet that provides all the necessary nutrients is crucial for human development and health, especially during pregnancy, as the mother's diet directly impacts the foetus's development. The ketogenic diet (KD), a high-fat, low-carbohydrate, and adequate protein diet, has gained popularity for weight maintenance and bodybuilding. While it has proven effective in treating epilepsy, obesity, neurodegenerative diseases, and metabolic disorders, its safety during pregnancy is questionable.
Several studies on mice and rats have investigated the effects of KD on embryonic growth and development. Results indicate that KD during pregnancy leads to alterations in embryonic organ growth, specifically the heart and brain. There were differences in the volume of brain regions such as the hypothalamus, thalamus, mid-brain, and pons at different time points during development. These alterations may be associated with potential organ dysfunction and behavioural changes in postnatal life.
Additionally, studies on neonatal rats have shown that KD impairs neurological development and affects the biochemical composition of maternal brains. There was a significant reduction in body mass and delays in neurological development in the offspring of KD-fed rats. Furthermore, KD during pregnancy may increase susceptibility to fatal ketoacidosis during lactation.
While these studies provide valuable insights, the applicability of these findings to humans is uncertain. There is limited research on the effects of KD in pregnant humans, and the long-term impacts on the offspring are not yet known. However, it is essential to consider that KD may lead to epigenetic changes in the foetus, impacting the child's health and functioning in adulthood.
In conclusion, while KD has shown promising results in treating various health conditions, its safety during pregnancy is a concern. The potential risks of KD on embryonic growth, neurological development, and maternal health in humans warrant further investigation. Until more research is conducted, pregnant women should proceed with caution and consult healthcare professionals before adopting KD during pregnancy.

Maternal health
A ketogenic diet is a high-fat, low-carbohydrate diet that has been used to treat epilepsy and obesity. It is also used for weight maintenance and body-building purposes in healthy adults. While the ketogenic diet has gained popularity, there are concerns about its safety during pregnancy.
Pregnant women are often advised to eat a low-fat diet with plenty of fruits, vegetables, and healthy grains. This is because a balanced diet, sufficient in all nutrients, is crucial to the health of the mother and the appropriate development of the fetus. The fetus's exposure to a ketogenic diet in utero may lead to increases or decreases in the rate of organ development and neurobehavioral changes.
Studies have shown that a ketogenic diet during pregnancy may result in alterations in embryonic organ growth, which could be associated with organ dysfunction and behavioral changes in postnatal life. In one study, mouse embryos exposed to a ketogenic diet in utero had a larger heart but a smaller brain, pharynx, cervical spinal cord, hypothalamus, midbrain, and pons. However, it is important to note that these findings may be due to the insufficient protein content of the ketogenic diet used in the mouse studies rather than fetal exposure to higher ketone levels.
Furthermore, a ketogenic diet can contribute to mineral and vitamin deficiencies, hypoproteinemia, the development of hepatic steatosis, and kidney stones. Folic acid, for example, is found in carbohydrate-rich foods and is key to the brain and spine development of the fetus. Removing these foods from a pregnant woman's diet can be dangerous.
While there is limited research on the effects of a ketogenic diet during pregnancy, the available evidence suggests that it may be harmful to maternal health. Therefore, it is recommended that women avoid a ketogenic diet when trying to conceive, during pregnancy, and while lactating.
