The carnivore diet, an extreme version of the ketogenic diet, has gained popularity for its potential for rapid weight loss and symptom relief for certain health conditions. This article explores the carnivore diet, its potential benefits and drawbacks, and why you might not be achieving ketosis while following it.
What is the Carnivore Diet?
The carnivore diet is a restrictive eating plan that primarily consists of animal products. It includes meat, fish, poultry, eggs, and some dairy products like butter and cheese. All plant-based foods, such as vegetables, fruits, grains, legumes, seeds, and nuts, are excluded.
How the Carnivore Diet Relates to Ketosis
The carnivore diet is considered a type of ketogenic diet because it severely restricts carbohydrate intake. Ketogenic diets, or "keto" diets, are very low in carbohydrates and high in fat and protein. The extreme limitation of carbs forces the body into a physiological state called ketosis. In ketosis, the body burns fat for fuel instead of glucose, leading to elevated ketone levels. This can result in weight loss and changes in appetite and energy levels.
Potential Benefits of the Carnivore Diet
The carnivore diet has garnered attention due to claims of various health benefits, including:
- Rapid weight loss: The diet's high protein and fat content can promote satiety and reduce calorie intake, leading to weight loss.
- Blood sugar control: By eliminating carbohydrates, the carnivore diet may help regulate blood sugar levels, potentially benefiting individuals with type 2 diabetes.
- Symptom relief: Some individuals with certain health conditions may experience symptom relief due to the elimination of common allergens and irritants like gluten, dairy (to some extent), and plant-based compounds such as lectins or oxalates.
- Simpler food-related decision-making: From grocery shopping to meal planning to food preparation.
- No counting carbs, tracking calories, counting portions, or following complicated recipes.
- No rigid eating windows to follow, like with intermittent fasting.
Potential Drawbacks and Risks
Despite the potential benefits, the carnivore diet also carries several risks and disadvantages:

- Nutrient deficiencies: Excluding all plant-based foods increases the risk of nutritional deficiencies, including vitamins C, E, and K, folate, and magnesium.
- Increased risk of heart disease: The high saturated fat content of many animal products may negatively impact heart health and cholesterol levels when consumed in excess.
- Digestive problems: The lack of dietary fiber can lead to constipation or diarrhea, gas, bloating, and an increased risk of colon cancer.
- Renal stress: The high protein intake can strain the kidneys and increase the risk for kidney stones.
- Restrictive nature: The diet's highly restrictive nature can make it challenging to maintain over time.
Reasons Why You Might Not Be in Ketosis on the Carnivore Diet
Even though the carnivore diet is inherently ketogenic, several factors can prevent you from achieving or maintaining ketosis:
Insufficient Fat Intake:
- The goal of the carnivore diet is to have a high fat-to-protein ratio to induce fat burning. If this ratio is off, you may lose weight more slowly.
- On a keto diet, fat should make up 55-60% of a person’s daily intake. If a person does not consume enough fat on a keto diet, they may not feel full. This can lead to snacking and consuming more calories than a person needs, resulting in weight gain.
Excessive Protein Consumption:
- Eating too much protein relative to fat can stall weight loss in the long run. When you consume excess protein, your body can convert it to glucose through a process called gluconeogenesis. This means you might unknowingly be providing your body with a steady stream of sugar, even while eating zero carbs.
- If protein makes up more than 35% of a person’s diet, they may not go into ketosis.
Hidden Carbohydrates:
- Some dairy products, like cheese and heavy cream, contain carbohydrates. Consuming too much of these can prevent ketosis.
Calorie Imbalance:

- Even in a zero-carb world, energy balance plays a crucial role in your weight loss efforts. Those delicious ribeye steaks and eggs fried in butter can pack quite a caloric punch.
- Overeating healthy foods is still overeating. When people stop losing weight on this diet, it's usually because they're eating too many calories, often from fatty foods like ribeye steak, bacon, and butter.
- Research from 2020 in the American Journal of Clinical Nutrition confirms that even meat-only diets follow the basic rule for weight loss: you must burn more calories than you eat. If you've hit a plateau on the carnivore diet, try using a calorie-tracking app for a few days to see what might be holding you back-often, it's those fatty cuts of meat.
Meal Timing:
- If you're eating too frequently throughout the day, you're providing a constant supply of energy, which, in excess, will always be stored as body fat. Consider spacing out your meals without snacking in between to allow your body to fully process each meal.
Lifestyle Factors:
- Weight loss plateaus can occur due to many factors beyond your diet, like not getting enough quality sleep, poor mental health, and being stressed out all the time.
- Poor sleep can throw your hunger hormones into chaos.
- Chronic stress floods your body with cortisol, making it more likely to hold onto fat stores. High stress is also known to promote belly fat storage.
- Additionally, drinking too much alcohol can displace the amount of carbs you’re getting, leading to an increase in calories.
Hormonal Imbalances:
- Imbalances in thyroid hormones and insulin sensitivity can lead to weight gain and metabolic issues.
Medications and Supplements:
- Certain medications and supplements can interfere with your weight loss efforts on the carnivore diet.
How to Know if You're in Ketosis
Several signs and symptoms can indicate whether you're in ketosis:

- Bad breath: Elevated ketone levels cause the bad breath. The specific culprit is acetone, a ketone that exits the body in your urine and breath
- Weight loss: You may experience both short- and long-term weight loss when switching to a keto diet
- Increased ketones in the blood: The most reliable and accurate method of measuring ketosis is to measure your blood ketone levels using a specialized meter. Nutritional ketosis is defined as blood ketones equal to or above 0.5 millimolar (mM)
- Increased ketones in the breath: Another way to measure blood ketone levels is a breath analyzer. It monitors acetone, one of the three main ketones in your blood during ketosis
- Appetite suppression: Many people report decreased hunger while following a keto diet
- Increased focus and energy: Long-term keto dieters often report increased focus and energy
- Short-term fatigue: The initial switch to a keto diet can be one of the biggest issues for new dieters. Well-known side effects can include weakness and fatigue
- Short-term decreases in performance: Removing carbs can lead to general tiredness at first. This includes an initial decrease in exercise performance.
- Digestive issues: Digestive issues such as constipation and diarrhea are common side effects in the beginning
- Insomnia: A lot of people report insomnia or waking up at night when they first reduce their carbs drastically
Tips to Achieve Ketosis on the Carnivore Diet
- Track your macronutrient intake: Ensure you're consuming enough fat and limiting protein to achieve the desired fat-to-protein ratio.
- Monitor your ketone levels: Use a blood ketone meter or breath analyzer to track your ketone levels and adjust your diet accordingly.
- Time your meals: Space out your meals to allow your body to fully process each meal and burn fat.
- Manage stress and prioritize sleep: Address lifestyle factors like stress and sleep to optimize hormone levels and support weight loss.
- Consult a healthcare professional: Rule out any underlying hormonal imbalances or medical conditions that may be hindering your progress.
Alternatives to the Carnivore Diet
If you're struggling to achieve ketosis or experiencing negative side effects on the carnivore diet, consider alternative approaches to weight loss and health improvement:
- Balanced diet: A balanced diet with lean protein, nutrient-rich carbohydrates, and healthy fats can be a more sustainable approach to weight loss.
- Ketogenic diet: A less restrictive ketogenic diet that includes a variety of low-carb vegetables and fruits can provide essential nutrients and fiber.
- Mediterranean diet: The Mediterranean diet, rich in fruits, vegetables, whole grains, and healthy fats, is associated with numerous health benefits.
The Importance of Professional Guidance
Navigating the carnivore diet and achieving ketosis can be challenging. Consulting a registered dietitian or healthcare professional can provide personalized guidance and support. They can help you:
- Evaluate whether the carnivore diet aligns with your health goals.
- Identify reasons why your weight loss has stalled.
- Suggest alternatives if the carnivore diet is not working for you.
- Develop a custom nutrition plan tailored to your individual needs.
