The carnivore diet, a highly restrictive eating plan that focuses exclusively on animal products, has gained traction in recent years. Proponents claim it offers benefits such as weight loss, improved blood sugar control, and reduced inflammation. However, due to its restrictive nature, it also raises concerns about nutritional deficiencies and potential health risks. This article explores the potential results of the carnivore diet for women, weighing the purported benefits against the known risks, and offering a balanced perspective.
What is the Carnivore Diet?
The carnivore diet is an eating plan that consists entirely of animal products, such as meat, fish, poultry, eggs, and limited amounts of dairy. It eliminates all plant-based foods, including fruits, vegetables, grains, legumes, nuts, and seeds. This makes it even more restrictive than other low-carb diets like the keto or Atkins diet, which still allow for some carbohydrate intake.
The diet's core principle is that by removing carbohydrates, the body will switch to burning fat for fuel through a process called ketosis, leading to weight loss and other health benefits. Some proponents also believe that eliminating plant-based foods can reduce inflammation and improve overall health.
Foods Allowed and Avoided
Allowed Foods:
- Beef (steak, ground beef, etc.)
- Pork (chops, bacon, ribs)
- Poultry (chicken, turkey)
- Fish and seafood (salmon, tuna, shrimp, etc.)
- Organ meats (liver, kidney, heart)
- Eggs
- Limited amounts of full-fat dairy (cheese, butter, heavy cream)
Foods to Avoid:
- All fruits and vegetables
- Grains (rice, bread, pasta)
- Legumes (beans, lentils)
- Nuts and seeds
- Processed foods
- Sugary drinks
Potential Benefits of the Carnivore Diet
While scientific research on the carnivore diet is limited, some proponents and anecdotal reports suggest potential benefits.
- Weight Loss: By eliminating carbohydrates, the body enters ketosis, using fat for energy. This can lead to increased metabolism and weight loss.
- Blood Sugar Management: The diet may stabilize blood sugar levels by preventing spikes caused by carbohydrate consumption.
- Reduced Inflammation: Some believe that eliminating plant-based foods can reduce inflammation in the body, although red meat can also promote inflammation.
- Improved Mental Clarity: Anecdotal evidence suggests that some individuals experience greater mental clarity and focus on the carnivore diet.
- Better Sleep: Some individuals report that they fall asleep easier, their sleep quality was better, and they woke up fresh and sharp every morning.
One survey of over 2,000 people following the carnivore diet for 9-20 months reported improvements in BMI, energy levels, sleep, strength, endurance, memory, and focus. Many participants with diabetes were also able to reduce or eliminate their diabetes medication. However, this study relied on self-reported data and lacked objective measurements, highlighting the need for further research.

Risks and Side Effects
The carnivore diet also carries potential risks and side effects that women should consider.
- Nutrient Deficiencies: Eliminating entire food groups can lead to deficiencies in essential vitamins and minerals, such as fiber, potassium, vitamin C, folate, thiamin, magnesium, and calcium.
- Heart Disease: The high saturated fat content of the carnivore diet may raise LDL cholesterol levels, increasing the risk of heart disease.
- Cancer: High consumption of red and processed meats has been linked to an increased risk of colorectal and other cancers.
- Digestive Problems: The lack of fiber can lead to constipation, while the high fat content may cause diarrhea in some individuals.
- Muscle Cramps: Electrolyte imbalances due to nutrient deficiencies can cause muscle cramps, dizziness, fatigue, and weakness.
- Kidney Problems: High protein intake can put added stress on the kidneys, potentially affecting their long-term function and increasing the risk of kidney stone formation.
- Hormonal Imbalances: Restrictive diets can disrupt the hypothalamic-pituitary-ovarian (HPO) axis, which regulates menstrual cycles. Women may experience changes in their menstrual cycles, fluctuating energy levels, or shifts in libido.
- Increased Cortisol Levels: When carbohydrate intake drops sharply, the body may increase cortisol production, a stress hormone that can lead to water retention and fat storage.
- Triggering Disordered Eating: Restrictive diets can be triggering for women recovering from disordered eating, leading to cycles of "perfect" or "failing" with food.
Considerations for Women
Women's bodies may respond differently to restrictive diets compared to men. Factors such as hormonal fluctuations, life stages, and emotional needs should be considered.
- Hormonal Health: The impact of the carnivore diet on hormonal health has not been adequately researched. Restrictive diets can affect hormone levels, potentially leading to irregular menstrual cycles or other hormonal imbalances.
- Energy Levels: Without adequate carbohydrate intake, the adrenal glands can become taxed, resulting in inconsistent energy and mood fluctuations.
- Weight Loss: While some women may experience initial weight loss on the carnivore diet, chronic stress on the body from extreme dietary changes can lead to increased cortisol, which may promote water retention and fat storage.
Nutrient Adequacy
A recent study assessed the micronutrient adequacy of four versions of the carnivore diet against national nutrient reference values (NRVs). The study found that the carnivore diet met several NRV thresholds for nutrients such as riboflavin, niacin, phosphorus, zinc, Vitamin B6, Vitamin B12, selenium, and Vitamin A, and exceeded the sodium threshold. However, it fell short in thiamin, magnesium, calcium, and Vitamin C, and in iron, folate, iodine and potassium in some cases. Fibre intake was significantly below recommended levels.
Is the Carnivore Diet Right for You?
The carnivore diet is a highly restrictive eating plan with potential benefits and risks. It is essential to consult with a healthcare professional or registered dietitian before starting this diet, especially for women with pre-existing health conditions or a history of disordered eating.
A balanced and varied diet that includes fruits, vegetables, whole grains, and lean protein sources is generally recommended for optimal health. While limiting simple carbohydrates and added sugars may be beneficial, completely eliminating entire food groups may lead to nutrient deficiencies and other health problems.

Alternatives to the Carnivore Diet
If you're interested in exploring alternative dietary approaches, consider the following:
- Ketogenic Diet: A low-carbohydrate, high-fat diet that allows for some vegetable and fruit intake.
- Paleo Diet: Focuses on whole, unprocessed foods similar to what our ancestors ate, including lean meats, fish, fruits, vegetables, nuts, and seeds.
- Mediterranean Diet: Emphasizes fruits, vegetables, whole grains, legumes, nuts, seeds, and olive oil, with moderate amounts of fish and poultry.
