Keto And Pregnancy: A Healthy Combination?

The keto diet is a high-fat, low-carb, and moderate-protein eating plan that was originally developed to treat epilepsy. The diet causes hormonal and chemical changes in the body, tapping into its own fat sources and inducing a state called ketosis. While the keto diet is popular, there is limited research on its impact on long-term health. There is even less research on the effects of the keto diet during pregnancy, and it is not considered ethical to use pregnant women as subjects in clinical studies. However, some studies on pregnant mice have shown that the keto diet may alter embryonic growth and development, which could lead to future organ dysfunction and behavioural changes. Given the limited research and potential risks, most doctors and nutritionists recommend against the keto diet during pregnancy.

Keto diet and nutrient deficiencies

The keto diet is a high-fat, low-carbohydrate, adequate-protein diet. It is often recommended for weight loss and body-building. However, its efficacy for these purposes does not necessarily translate to its suitability for pregnant women.

Pregnant women need a variety of colourful foods to fuel their growing bodies and support the development of the fetus. The keto diet may not be a good option during pregnancy because it can prevent the consumption of nutrient-dense foods, including fresh, dried, and cooked fruits and vegetables.

Nutrient Deficiencies

The keto diet may cause nutrient deficiencies in pregnant women, including:

• Vitamin D (vital for healthy bones and teeth)
• Vitamin E (vital for healthy muscles and blood)
• Vitamin B-12 (vital for a healthy spinal cord and nerves)
• Folic acid (vital for a healthy spinal cord and the prevention of spina bifida)

These deficiencies can lead to problems in the baby's growth and development.

Saturated Fat

The keto diet does not differentiate between healthy, lean protein and kinds with lots of saturated fats, like beef and pork. The diet can lead to the overconsumption of unhealthy meat, oils, butter, and lard, which may cause higher cholesterol and put a strain on the heart and pregnancy.

Other Risks

The keto diet may also cause "keto flu", with side effects such as nausea, vomiting, tiredness, and aches. In addition, there is a risk of ketoacidosis, a serious medical condition characterised by high blood glucose and ketone levels, which can be life-threatening for both mother and infant.

There is also limited evidence from animal studies that exposure to ketones or a ketogenic diet during pregnancy may cause changes to embryo development and fetal developmental abnormalities, suggesting the potential for causing birth defects.

Recommendations

Due to the potential risks, it is recommended that pregnant women adopt a more flexible low-carb approach, with a carbohydrate goal of 75-150 grams per day, unless otherwise instructed by a healthcare provider. This approach provides the benefits of low-carb eating without the potential risks associated with ketogenic eating during pregnancy.

It is important to consult with a doctor or nutritionist before starting any diet, especially during pregnancy.

Keto diet and saturated fat

The keto diet is a high-fat, low-carbohydrate, adequate-protein diet that has gained popularity as a lifestyle diet for weight maintenance and body-building. It derives most of its calories from fat, with 75% to 90% of daily calories coming from fat. This high-fat requirement means that saturated fats are a significant component of the keto diet. However, the potential health risks associated with saturated fat have sparked concerns about the diet's safety, especially during pregnancy.

Health Risks of Saturated Fat

Saturated fat has long been considered unhealthy due to its association with heart disease. This belief stems from experimental findings that replacing saturated fat with unsaturated fat lowers low-density lipoprotein (LDL) cholesterol, which is a risk factor for heart disease. However, recent research suggests that the relationship between saturated fat and heart disease is more complex. The effect of saturated fat on heart health depends on various factors, including individual responses, food sources, and overall diet composition.

Some studies have failed to find a clear link between saturated fat intake and heart disease or all-cause mortality. For instance, a 2015 meta-analysis of observational studies found no association between saturated fat intake and heart disease, all-cause mortality, or any other disease. Similarly, a 2017 meta-analysis of cohort studies showed no significant association between saturated fat intake and death from heart disease.

The keto diet includes moderate levels of protein (about 10% of calories) and places no restrictions on fat intake (70-80% of calories). As a result, keto diets can be high in saturated fat, especially when fatty cuts of meat, processed meats, lard, butter, cream, and cheese are consumed. These foods are allowed or even encouraged on keto diets, and they contribute significantly to saturated fat intake.

Health Risks During Pregnancy

During pregnancy, a balanced diet is crucial as the mother's body works to maintain a healthy weight and provide essential nutrients for the developing fetus. Restricting carbohydrates and consuming excessive saturated fat on the keto diet can lead to nutrient deficiencies and increase health risks for both the mother and the baby.

One of the main concerns with the keto diet during pregnancy is the risk of nutrient deficiencies. The keto diet limits fruits and vegetables, which are rich sources of vitamins, iron, and folate, essential for the baby's growth and development. Additionally, pregnant women following the keto diet may not meet their increased requirements for certain nutrients like vitamin D, vitamin E, vitamin B-12, and folic acid.

Another concern is the high saturated fat content of the keto diet. Most doctors recommend limiting saturated fats during pregnancy to control weight gain and avoid complications like pregnancy-related high blood pressure. Excessive saturated fat intake can lead to higher cholesterol levels in the mother, putting a strain on her heart and pregnancy.

Furthermore, the keto diet's lack of restriction on processed meats and added chemicals may also pose risks to the developing baby. The diet's high saturated fat content and potential nutrient deficiencies make it generally unsafe for pregnant women.

While the keto diet may offer some benefits for weight management and certain health conditions, its high saturated fat content and restrictive nature can be detrimental during pregnancy. Pregnant women are advised to follow a balanced diet that includes a variety of fruits, vegetables, grains, lean protein, and dairy products to ensure adequate nutrient intake for both mother and baby. More research is needed to fully understand the long-term effects of the keto diet, especially during pregnancy.

Keto diet and side effects

The keto diet is a high-fat, low-carbohydrate eating plan that has been advertised as a "miracle diet" and a solution to many health problems. However, there are several side effects and risks associated with the keto diet that people should be aware of before starting this diet. Here are some of the potential side effects and complications:

Nutrient Deficiencies:

The keto diet restricts carbohydrates, including fruits and most vegetables, which are rich sources of vitamins, iron, and folate. This can lead to nutrient deficiencies, especially in pregnant women who require higher doses of these nutrients for their growing baby. Some of the vitamins and minerals that may be lacking in the keto diet include vitamin D, vitamin E, vitamin B-12, and folic acid.

Increased Saturated Fat Intake:

The keto diet encourages a high intake of fat, which can lead to an increased consumption of unhealthy meats, oils, butter, and processed meats. This can result in higher cholesterol levels, putting strain on the heart and potentially causing health problems during pregnancy.

Gastrointestinal Issues:

Common side effects of the keto diet include gastrointestinal problems such as constipation, diarrhea, nausea, and vomiting. Diarrhea is particularly frequent due to the body's difficulty in absorbing the high-fat content of the diet.

Kidney Stones:

The keto diet's focus on animal-based and high-fat foods can lead to an increased risk of kidney stones. This is because a high intake of animal products can make the blood and urine more acidic, leading to increased calcium excretion in the urine.

Ketoacidosis:

Ketoacidosis occurs when there is a buildup of too many ketones, or fat-burn byproducts, in the blood. This condition can be fatal if left untreated and is particularly risky for individuals with type 1 diabetes.

Reduced Athletic Performance:

Athletes may find that the keto diet negatively impacts their performance in high-intensity sports. Research has shown that participants performed worse in cycling and running tasks after following a ketogenic diet for four days compared to those on a high-carb diet.

Vitamin and Mineral Deficiencies:

The keto diet may lead to a lower intake of important vitamins and minerals, including folate, thiamin, vitamins A, B6, B12, C, E, and K. These nutrients are essential for various body functions and development, including bone health, metabolism, and red blood cell production.

Dehydration:

The keto diet can cause water loss before fat loss, leading to dehydration. Symptoms of dehydration include increased thirst, dark-colored urine, dizziness, and lightheadedness.

Yo-yo Dieting:

The keto diet can be difficult to maintain in the long term, leading to yo-yo dieting patterns. This can have negative effects on the body, including weight fluctuations and increased mortality risk.

Other Side Effects:

Other potential side effects of the keto diet include bad breath, fatigue, constipation, irregular menstrual cycles, decreased bone density, and sleep issues. Additionally, there may be risks related to blood cholesterol levels and long-term health impacts due to the lack of certain fruits, vegetables, grains, and legumes in the diet.

It is important to note that the keto diet is not recommended for everyone, especially those with chronic conditions such as high blood pressure, diabetes, or liver or kidney problems. Pregnant women should also avoid restrictive diets like keto and instead focus on a balanced diet with a variety of fruits, vegetables, grains, lean protein, and dairy products to ensure adequate nutrition for both mother and baby.

Research on keto diet during pregnancy

There is limited research on the effects of the keto diet during pregnancy, and most of the studies have been conducted on animals.

A 2013 study on mice found that a keto diet during pregnancy resulted in baby mice having a larger heart and smaller brain than usual. Another study in 2015 on mice found that the babies of mothers on a keto diet had a higher risk of anxiety and depression in adulthood.

The keto diet is high in fat and protein and low in carbohydrates. It has been used to treat epilepsy since the 1920s. The diet is based on ketogenesis, where the body's cells use fat instead of glucose for energy, resulting in the production of ketones.

The keto diet is challenging to follow correctly, and it can be difficult to know if one is in ketosis. The diet restricts fruits and vegetables, which are important sources of vitamins, iron, and folate for pregnant women. It may also lead to deficiencies in vitamins and minerals that are vital for the baby's growth and development, such as vitamin D, vitamin E, vitamin B-12, and folic acid.

The keto diet is also high in saturated fat, which can cause higher cholesterol and put a strain on the heart and pregnancy. Additionally, the diet does not restrict processed meats, which may contain chemicals and colors that are unhealthy for the mother and baby.

There is limited research on the effects of the keto diet during pregnancy on humans. A 2017 case study found that the keto diet helped control epilepsy symptoms in two pregnant women, and they had normal, healthy pregnancies and deliveries. However, more research is needed to determine the safety and effectiveness of the keto diet during pregnancy.
