Feeling Cold on Carnivore Diet
Potential Reasons and Solutions
Individuals on a carnivore diet consume primarily animal products, excluding plant-based foods. This regimen emphasizes proteins and fats from animal sources and suggests that these should form the bulk of nutritional intake. While the carnivore diet has been associated with various health benefits like weight loss and improved energy levels for some, a noticeable side effect reported by individuals is an increased feeling of coldness, regardless of environmental conditions.
The sensation of feeling unusually cold while on the carnivore diet may be attributed to several factors. One prominent theory is that the substantial reduction in carbohydrate intake can affect thermogenesis, the body’s mechanism for generating heat. Carbohydrates play a vital role in this process, and their scarcity in the diet can lead to a decreased ability to produce body heat. Additional factors contributing to this feeling could include metabolic adjustments and changes in body composition, such as loss of insulating body fat.
Understanding this side effect is crucial for those considering or currently on the carnivore diet. Acknowledging the possible link between the diet and thermoregulation can help individuals anticipate and manage this condition more effectively. It's important to monitor personal health and consult healthcare providers to ensure dietary choices align with one's specific needs and health goals.
Understanding the Carnivore Diet
The Carnivore Diet is an all-meat, high-protein regimen with an emphasis on consuming exclusively animal products, while other diets may include a variety of food groups.
Overview of Carnivore Diet
The Carnivore Diet is characterized by its exclusive focus on animal-based products, excluding all plant-based foods. It is high in protein and fats, and nearly devoid of carbohydrates, placing it in the realm of low-carb diets. Proponents believe this diet mimics the eating patterns of ancestral human diets.
Comparison with Other Diets
The Carnivore Diet differs significantly from other low-carb diets like the ketogenic diet. While both limit carbohydrate intake, the ketogenic diet includes a wider variety of foods and focuses on achieving ketosis, a metabolic state where the body burns fat for fuel in the absence of carbohydrates. In contrast, the Carnivore Diet does not necessarily aim for ketosis, but rather sustains energy through a high intake of proteins and fats from animal sources.
Potential Benefits and Health Claims
Advocates of the Carnivore Diet claim several health benefits, including weight loss, increased energy, and better digestive health due to the exclusion of plant-based irritants. These claims highlight the diet's potential role in reducing inflammation and adherence to what is perceived as a more 'natural' human diet. However, it is important to note these benefits are anecdotal and proper scientific studies are needed to substantiate them.
Nutritional Considerations
In transitioning to a carnivore diet, it is crucial to understand how the major nutrient groups, namely fats, proteins, and vitamins and minerals, play distinct roles in overall health and body temperature regulation.
Role of Fats and Proteins
Fats serve as a critical source of energy on a carnivore diet and are essential for maintaining body warmth. Sources such as steak and organ meats are rich in fats that help sustain energy levels. Proteins, found abundantly in meat, eggs, and liver, are necessary for the body's repair processes and metabolic functions.
Fats: Primary energy source, needed for warmth
Includes: Steak, organ meats
Proteins: Repair and metabolic functions
Includes: Meat, eggs, liver
Minimizing Carbohydrate Intake
The carnivore diet minimizes carbohydrate intake by focusing on animal products and eliminating plant fibers. This drastic reduction in carbohydrates can affect body temperature as the body adapts to using fats for fuel instead of glucose.
Carbohydrates: Drastically reduced, no fiber
Vitamins and Minerals
A well-formulated carnivore diet can provide essential vitamins and minerals, though one must ensure diversity in the foods consumed. Organ meats like liver are high in vitamins, including vitamin C, which is important for immune function. The diet's restriction can make it challenging to obtain some nutrients, thus careful selection of foods like eggs which offer a variety of vitamins, is important.
Vitamin C: Found in organ meats like liver
Eggs: Provide a variety of vitamins and minerals
Adaptation and Side Effects
This section focuses on the adaptation period to a carnivore diet, often accompanied by a range of physical symptoms. It outlines the need for managing electrolyte balance and hydration to mitigate side effects.
Adaptation Period
During the initial transition to a carnivore diet, one's body shifts from using carbohydrates to fats for energy, a state known as ketosis. The adaptation period can last from a few days to several weeks. Individuals may experience notable weight loss during this time. However, this phase is also marked by an array of side effects as the body adjusts to the absence of carbohydrate intake.
Common Physical Symptoms
Side effects during the adaptation phase may include:
Fatigue and Brain Fog: As the body learns to utilize fat for fuel, energy levels may temporarily diminish.
Headache and Nausea: These are common as the body detoxifies from previous dietary habits.
Diarrhea and Constipation: Changes in bowel movements occur due to the diet's high protein and fat content.
Flu-like Symptoms: Similar to the keto flu, individuals may feel unwell as a result of entering ketosis.
Managing Electrolyte and Hydration Levels
Proper hydration and electrolyte balance are critical to alleviate side effects. Key strategies include:
Increasing Sodium Intake: The addition of extra salt can counteract the loss of sodium through increased urination.
Drinking Bone Broth: A rich source of minerals, bone broth helps replenish electrolytes like magnesium and potassium.
Using Supplements: Magnesium citrate can be beneficial for preventing muscle cramps.
Maintaining hydration and electrolyte levels often leads to an improvement in overall energy levels and a reduction in symptoms such as cramping and dizziness.

Physical and Mental Effects
Transitioning to a carnivore diet can significantly affect both physical and mental well-being, leading to various changes including energy levels and mood, sleep patterns, and digestive functions.
Energy and Mood Fluctuations
Adherence to a carnivore diet often results in changes to energy and mood. Individuals may experience increased energy due to stable blood sugar levels from consuming high-protein and high-fat foods. However, some may undergo mood swings, cravings for sugars and carbohydrates, or irritability as the body adjusts to the absence of these elements. Cortisol levels may fluctuate, impacting stress responses and mood stability.
Effects on Sleep and Stress
The elimination of carbohydrates can lead to alterations in sleep quality. For some, sleep may improve due to the diet's potential to stabilize blood sugar, while others might face initial insomnia or fatigue as their bodies adjust. Stress levels can be affected, too, since the diet significantly changes habitual eating patterns and the body's hormone balance, including cortisol, which regulates the stress response.
Digestive Changes
Carnivore diet followers might experience varied digestive issues as their gastrointestinal (GI) systems adapt. The absence of fiber-rich foods can lead to constipation, while the body's initial reaction to high meat consumption could cause diarrhea. It's important for individuals to monitor and react to these digestive changes, potentially incorporating sources of natural enzymes and focusing on adequate hydration to mitigate GI distress.
Health Impact and Medical Concerns
The transition to a carnivore diet can significantly affect the body's normal functioning, including hormone levels and gallbladder activity, as well as impacting the gut microbiome. Understanding the potential health impacts and medical concerns associated with this diet requires examining its influence on these systems.
Effects on Hormones and Gallbladder
A carnivore diet may lead to hormonal imbalances as it excludes certain food groups that provide essential nutrients. Specifically, the absence of carbohydrates can affect the thyroid hormone, which in turn can manifest as a sensation of feeling cold. Additionally, a high intake of fats requires increased bile production from the gallbladder. Over time, this could lead to gallbladder stress and potential issues such as gallstones.
Influence on Microbiome and Immune System
Microbiome Diversity:
Reduced: Lack of dietary fiber from vegetables can diminish the diversity of gut bacteria.
Impact on Immune System: This can compromise the immune function, since a significant part of the immune system is intertwined with the gut microbiome.
The absence of plant-based foods may lead to an imbalance in beneficial bacteria in the intestines. This imbalance could potentially trigger or exacerbate autoimmune diseases due to an altered immune response.
Addressing Nutrient Deficiencies
Common Deficiencies on a Carnivore Diet:
Vitamin C: Typically sourced from fruits and vegetables; a deficiency might affect tissue repair and immunity.
Fiber: Important for gut health, typically absent in an all-meat diet.
Magnesium and Calcium: Generally lower in meat, these minerals are vital for bone health.
To prevent nutrient deficiencies, individuals on a carnivore diet might need to be particularly mindful of sourcing all necessary vitamins and minerals. Supplements or a strategic inclusion of diverse animal-based foods could be necessary to meet the body's requirements.

Coping Strategies for Common Issues
When adhering to a carnivore diet, individuals may encounter several common issues such as low energy, digestive disturbances, and a lack of variety in their meals. Effective coping strategies can help mitigate these problems.
Mitigating Fatigue and Low Energy
To combat fatigue and low energy, individuals should focus on maintaining a balanced intake of fats and proteins. Including fatty cuts of meat like bacon can provide a sustained energy source, as fat is metabolized into ketones, an efficient fuel for the body. Additionally, one can consider eating smaller, more frequent meals to keep energy levels stable throughout the day.
Dealing with Digestive Problems
Digestive issues, including diarrhea, constipation, and bloating, can be addressed by:
Gradually increasing fat intake: This can help the body adapt to higher fat levels without overwhelming the digestive system.
Supplementing with ox bile: For those with difficulty digesting fats, ox bile supplements can assist in the emulsification and absorption of dietary fats.
Incorporating dairy: If tolerated, dairy products such as cheese can help firm stools and add beneficial bacteria to the gut. However, individuals should be cautious as dairy can also be a source of digestive trouble for some.
Including seafood: Seafood is rich in omega-3 fatty acids, which can help reduce inflammation in the gut and improve digestive health.
Improving Food Variety and Flavor
While the carnivore diet primarily consists of animal products, there is room for variety:
Expand the range of animal-based foods: Incorporating different types of meat, such as beef, pork, lamb, organ meats, and a variety of seafood, can prevent dietary boredom and improve nutrient intake.
Use eggs: Eggs are not only versatile and flavorful but also provide essential vitamins and minerals that may be lacking in a strictly meat-based diet.
Experiment with cooking methods: Different cooking methods like grilling, roasting, slow-cooking, or smoking can dramatically change the flavor profile and texture of meats, offering variety in taste and culinary experience.
Supporting Your Diet with Supplements
Adhering to a carnivore diet potentially leads to specific nutritional deficits. Supplementation may be vital to ensure adequate intake of vitamins, minerals, and other dietary elements crucial for optimal body function.
Essential Supplements for Carnivores
On a carnivore diet, individuals may need to consider supplementing vitamins and minerals that are typically lower in animal products. Vitamin A is crucial for organ function and particularly for eyesight, with a daily recommendation ranging from 700 to 900 micrograms. Because vitamin levels may vary depending on the meat source, a vitamin A supplement could be beneficial. Further, it’s essential to monitor fat intake as it plays a key role in vitamin absorption.
Vitamin C: While often associated with fruits, vitamin C can be found in organ meats; however, some on this diet might opt for a supplement to ensure adequate levels.
Magnesium Citrate: An important electrolyte that supports muscle and nerve function. Since it might not be sufficiently provided in a carnivore diet, supplementation could be necessary.
Understanding the Role of Electrolytes
Electrolytes such as sodium, potassium, and magnesium are vital for maintaining proper fluid balance, nerve transmission, and muscle function. Individuals on a carnivore diet may experience shifts in electrolyte balance due to diet changes and should consider the following:
Sodium: Found in abundance in meat, but additional intake may be required, especially for those who are active and sweat regularly.
Potassium: Critical for heart and muscle function, it should be balanced with sodium intake. Meat can be a good source, but supplementation may be helpful in some cases.
Magnesium: As magnesium works closely with potassium, individuals may use magnesium citrate supplements to promote optimal levels.
Considerations for Fiber and Probiotics
While the carnivore diet does not typically include plant-based sources of fiber and probiotics, these components support the microbiome and digestive system. For carnivores, especially those experiencing digestive issues, a probiotic supplement can help maintain intestinal health. However, fiber supplements may not be necessary for all individuals following this diet, as some may adapt well to the absence of fiber from plant sources. Careful monitoring of digestive comfort and function will guide the need for these supplements.
