The carnivore diet, also known as the zero-carb diet, is a restrictive eating plan that advises the consumption of only animal products, primarily meat, eliminating all plant-based foods. Pregnancy is a critical time for nutrition, as the developing fetus relies entirely on the mother's nutrient intake for growth and development. The American Pregnancy Association emphasizes the importance of a balanced diet during pregnancy to support both maternal and fetal health.
Understanding the Carnivore Diet
The carnivore diet is a highly restrictive dietary regimen that eliminates all plant-based foods, relying exclusively on animal products such as meat, fish, eggs, and limited full-fat dairy-based products like cheese and butter. The carnivore diet is very restrictive. Avid fans of the carnivore diet say it has a range of benefits. While it may seem like a new trend, meat-only diets have been touted for hundreds of years, with some claiming it reflects the natural way our ancestors ate. This approach stands in stark contrast to conventional dietary guidelines, which emphasize the importance of a variety of food groups for optimal health.
Potential Benefits of a Carnivore Diet During Pregnancy
While the carnivore diet may seem unconventional, it does offer some potential benefits that could be relevant during pregnancy.
High Protein Intake
A carnivore diet naturally provides high amounts of protein, which is crucial for fetal growth and development. Adequate dietary intake of animal source protein foods is critical in pregnancy due to their complete amino acid profile; contents and bioavailability of lysine, sulfur amino acids, and threonine; and associated insulin-like growth factors, iron, zinc, and vitamin B-12. The Academy of Nutrition and Dietetics recommends that pregnant women consume 71 grams of protein daily. Animal-based food products, in general, contain the highest amount of protein per unit energy, and protein derived from animal foods is considered the best-quality protein.
Iron and B12 Availability
Animal products are rich sources of heme iron and vitamin B12, both essential for preventing anemia and supporting fetal neurological development. Iron, folate, and vitamin B-12 are crucial in erythropoiesis. Folate and vitamin B-12 are required for erythroblast proliferation and differentiation whereas iron is an important constituent of hemoglobin, which is essential for the transfer of oxygen to tissues. The absorption of heme iron from animal sources is more efficient than non-heme iron from plant-based foods.

Potential Benefits for Specific Conditions
Some supporters of the carnivore diet suggest that eliminating plant-based foods may benefit individuals with autoimmune conditions by reducing exposure to potential dietary triggers, such as lectins and oxalates.
Concerns and Risks Associated with a Carnivore Diet in Pregnancy
Despite the potential benefits, there are significant concerns and risks associated with following a carnivore diet during pregnancy.
Micronutrient Deficiencies
A strict carnivore diet may lead to deficiencies in essential micronutrients, including folate or folic acid, vitamin D, calcium, and vitamin C. These nutrients play crucial roles in fetal development and maternal health. For example, folate is vital for preventing neural tube defects, while vitamin C supports immune function and iron absorption.
Lack of Fiber and Plant-Based Nutrients
The absence of plant-based foods in the carnivore diet eliminates important sources of fiber, antioxidants, and phytonutrients. These compounds contribute to gut health, reduce inflammation, and support overall well-being during pregnancy. Not getting enough fiber from your diet could cause constipation.
Potential for High Saturated Fat Intake
Animal-based diets are high in saturated fat, which can raise low-density lipoprotein (LDL) cholesterol. That’s the unhealthy kind of cholesterol that increases your risk of heart disease and stroke. The American Heart Association recommends limiting red meat to protect your ticker.

Kidney Function Concerns
Eating a diet high in animal protein can place added stress on your kidneys, which may affect their long-term filtering function. Eating more meat also may contribute to kidney stone formation.
Essential Nutrients for Pregnancy and Their Sources in a Carnivore Diet
If considering a carnivore diet during pregnancy, it's crucial to understand how to obtain essential nutrients.
Protein and Amino Acids
Meat is an excellent source of complete proteins, providing all essential amino acids necessary for fetal growth and development. Lean meats, poultry, and fish are particularly beneficial during pregnancy.
Iron and B Vitamins
Red meat, organ meats, and poultry are rich in iron and B vitamins, including B12, which are crucial for preventing anemia and supporting fetal brain development.
Omega-3 Fatty Acids
Fatty fish, such as salmon and sardines, provide essential omega-3 fatty acids, particularly DHA and EPA. The International Society for the Study of Fatty Acids and Lipids (ISSFAL) recommends a minimum intake of 200 mg DHA per day during pregnancy for optimal fetal brain and eye development.

Calcium and Vitamin D
While dairy products are often eliminated in strict carnivore diets, some versions may include them. If included, dairy can provide calcium and vitamin D, essential for fetal bone development and maternal bone health.
Modifications to a Carnivore Diet for Pregnancy
To mitigate some of the risks associated with a strict carnivore diet during pregnancy, certain modifications can be considered.
Incorporating Organ Meats
Organ meats, such as liver and kidney, are nutrient-dense and can help address some micronutrient deficiencies. However, it's important to consume them in moderation due to their high vitamin A content, which can be harmful in excess during pregnancy.
Supplementation Recommendations
Pregnant women following a carnivore diet should consider supplementing with folate or folic acid, vitamin D, calcium, vitamin C, and a prenatal multivitamin. Always consult with a healthcare provider before starting any supplementation regimen during pregnancy.
Medical Considerations and Monitoring
Close medical supervision is essential for pregnant women considering a carnivore diet.
Regular Check-ups and Blood Tests
Pregnant women on a carnivore diet should undergo more frequent prenatal check-ups and blood tests to monitor nutrient levels, blood sugar, ketone levels, and fetal growth and development.
Consulting with Healthcare Professionals
It's crucial to work closely with an obstetrician, nutritionist, or dietitian experienced in high-protein diets during pregnancy. They can provide personalized guidance and monitor for potential complications.
Exploring Alternative Diets for Pregnancy Nutrition
Given the risks associated with a strict carnivore diet, it's important to consider alternative dietary approaches that can provide adequate nutrition during pregnancy.
Balanced Omnivorous Diet
The World Health Organization (WHO) recommends a balanced diet during pregnancy, including a variety of foods from all food groups. This approach ensures adequate intake of essential nutrients and reduces the risk of deficiencies.
Modified Ketogenic Approach
A modified ketogenic diet that includes some low-carb vegetables and berries may provide a middle ground between a strict carnivore diet and a conventional pregnancy diet. This approach can still offer the benefits of a high-fat, low-carb diet while providing some plant-based nutrients.
The Impact of Animal Source Foods (ASF) on Birth Outcomes in Resource-Limited Settings
Studies conducted in resource-limited settings, such as urban Tanzania, have examined the relationship between maternal dietary intake and birth outcomes. These studies highlight the importance of animal source foods (ASF) during pregnancy.
Study Design and Methodology
One study enrolled pregnant women attending prenatal clinics in Dar es Salaam. Dietary intake was assessed by 24-hour recalls during monthly prenatal clinic visits. The study outcomes included preterm birth, very preterm birth, low birth weight (LBW), small for gestational age (SGA), stillbirth, and neonatal death.
Key Findings
The study found that higher frequency of ASF protein intake was associated with a lower risk of neonatal death. Higher fish intake was associated with a lower risk of very preterm birth. Any meat intake was protective of preterm birth, very preterm birth, LBW, and neonatal death. Any egg intake was protective of very preterm birth.
Implications
These findings suggest that adequate dietary intake of animal source protein foods is critical in pregnancy due to their complete amino acid profile and the presence of essential nutrients like iron, zinc, and vitamin B-12.
Potential Negative Impacts of the Carnivore Diet
Going to a meat-based diet can bring side effects that negatively affect your health. Issues include:
- Heart disease: The carnivore diet is high in saturated fats that can raise your “bad cholesterol” (LDL) levels and put you at higher risk for heart disease.
- Cancer: Eating large amounts of red meat has been linked to increased risk for colorectal cancer, which can be divided into colon cancer and rectal cancer, as well as several other types of cancer.
- Digestive problems: Meat takes longer to digest, and slowing down that process can lead to constipation. Plus, the carnivore diet lacks fiber to help keep things moving along.
- Muscle cramps: The lack of key nutrients in a meat-based diet can lead to electrolyte imbalances that cause muscle cramps, as well as dizziness, fatigue, and general weakness.
- Kidney function: Eating a diet high in animal protein can place added stress on your kidneys, which may affect their long-term filtering function. Eating more meat also may contribute to kidney stone formation.
Carnivore Diet for Women
Women can benefit from various health effects when they go on a Carnivore Diet, from hormonal balance to fat loss and better mental clarity. But there might also be risks that women should consider before starting this low-carb, animal-based diet.
Women turn to the Carnivore Diet for different reasons than men. While men usually focus on fat loss or muscle gain, many women use Carnivore to heal problems with hormones, weight, digestive issues, skin flare-ups, or fatigue.
Unlike plant-based diets, Carnivore eliminates fiber, sugars, and plant toxins that can worsen women’s digestive and hormonal systems.
How Can the Carnivore Diet Help Women?
Women’s health is deeply influenced by hormones. They shape everything from mood and fertility to skin, metabolism, and bone strength. When these systems fall out of balance, the effects can be frustrating: irregular cycles, stubborn weight gain, hot flashes, or even mood swings.
That is why more women are turning to the Carnivore Diet, a zero-carb, animal-based diet that removes inflammatory foods and focuses on nutrient-dense proteins and fats. By providing daily macros from high-quality animal sources, this diet can support hormonal balance, clearer skin, steady energy, and even fertility.
Many women report more regular cycles on Carnivore. Lowering carbohydrates and eating more fat and protein stabilizes blood sugar, reducing stress on the ovaries and adrenal glands.
Benefits of the Carnivore Diet for Women Over 40
Women over 40 often face special health challenges like perimenopause, thyroid issues, insulin resistance, and increased inflammation.
The Carnivore Diet can help reduce these effects by managing blood sugar fluctuations and stabilizing hormones.
Consuming more protein helps preserve lean muscle mass, which usually declines as we age. Animal-based diets are also rich in iron, B12, and cofactors that support thyroid function and energy metabolism.
Conclusion and Recommendations for Expectant Mothers
While the carnivore diet may offer some benefits during pregnancy, such as high protein and iron intake, it also poses significant risks of nutrient deficiencies. Pregnant women considering this diet should carefully weigh the potential risks and benefits and consult with healthcare professionals before making any drastic dietary changes.
A more balanced approach, incorporating a variety of nutrient-dense foods from both animal and plant sources, is generally recommended for optimal maternal and fetal health. If choosing to follow a carnivore or modified carnivore diet, close monitoring and appropriate supplementation are essential to ensure a healthy pregnancy outcome.
