As more people explore different dietary approaches, the carnivore diet has gained traction due to its reported health advantages, including weight loss and blood sugar regulation. The carnivore diet is an eating plan that consists entirely of animal products. This includes meat, fish, poultry, eggs, and some dairy.
The carnivore diet slashes the glycemic load as it edges out carbohydrate sources in favor of animal-based products that contain high protein and fats. Anecdotal evidence supports its potential role in weight loss and blood sugar management. There is a mounting body of evidence supporting the link between the carnivore diet and improved mental health.
However, some people who have tried the carnivore diet have reported experiencing insomnia. Insomnia is a sleep disorder that is characterized by difficulty falling asleep, staying asleep, or both. It can be a short-term problem, or it can be chronic. It is important to consider individual differences and consult with a healthcare provider before making any significant dietary changes.
Potential Benefits of the Carnivore Diet
Before delving into the potential link between the carnivore diet and insomnia, it's important to acknowledge the diet's purported benefits. Some of these include:
- Weight Loss: The carnivore diet's emphasis on protein and fat can promote satiety and reduce overall calorie intake, potentially leading to weight loss.
- Blood Sugar Regulation: By eliminating carbohydrates, the carnivore diet may help stabilize blood sugar levels, which can be beneficial for individuals with diabetes or insulin resistance.
- Improved Mental Health: A 2023 study by the University of Southern Indiana and the University of Maryland suggests a reduction in anxiety and depression among meat consumers compared to meat abstainers. Various types of meat like fish, chicken, and beef contain nutrients that allow the smooth secretion of hormones and neurotransmitters that help regulate mood. These nutrients include essential amino acids like tryptophan, vitamin B12, iron, zinc, and omega-3 fatty acids.
- Skin Health: A high-carbohydrate and high-glycemic diet has been proven to contribute to acne formation. The carnivore diet slashes the glycemic load as it edges out carbohydrate sources in favor of animal-based products that contain high protein and fats. Additionally, chicken bones and cartilage are great sources of collagen, which helps inhibit inflammation, promote smoother skin, and slow skin aging.
- Increased Testosterone Levels: A carnivore diet also ensures sufficient zinc intake. Zinc is known to boost libido or sexual drive and increase testosterone levels, which improve sexual performance.
The Carnivore Diet and Sleep: What the Evidence Says
While anecdotal evidence suggests that some individuals experience improved sleep on the carnivore diet, scientific evidence on this topic is limited and sometimes contradictory.

- Protein and Sleep Quality: In a narrative review of the connection between diet and sleep quality, it was highlighted that a protein-rich meal plan is associated with enhanced sleep quality. Proteins are made of amino acids, and some amino acids can help you sleep better. It's well-known that tryptophan can improve sleep. Dietary proteins are sources of some amino acid precursors of two neurotransmitters relevant for biological rhythms, serotonin and melatonin, which are involved in sleep and alertness.
- Conflicting Studies: Some studies refute the claim that the carnivore diet improves sleep, stating instead that a consistent carnivore diet induces poor sleep, particularly among older adults.
- Saturated Fat: The carnivore diet's emphasis on meat could have you losing sleep if you choose meat that's high in saturated fat. Saturated fat can interfere with your sleep quality by reducing time in deep sleep and causing more sleep disruptions.
- Meat Consumption and Sleep in Older Adults: A study using data from 1,341 participants aged ≥60 years found that higher habitual meat consumption was associated with large changes in sleep duration and with poor sleep quality. Compared with individuals in the lowest tertile of meat consumption (<87 g/d), those in the highest tertile (≥128 g/d) showed increased incidence of a large decrease (≥2 h) in sleep duration. Higher consumption of meat was also associated with incidence of snoring and poor general sleep quality. Each 100 g/d increment in meat intake was associated with a 60% higher risk of both large sleep duration changes and poor sleep quality.
Potential Reasons for Insomnia on the Carnivore Diet
Several factors could contribute to insomnia in individuals following a carnivore diet:
- Dietary Changes and Adaptation: Any significant dietary change can disrupt the body's natural rhythms and hormonal balance, potentially affecting sleep. The body may need time to adjust to the carnivore diet, and sleep disturbances may be a temporary side effect.
- Carbohydrate Restriction: While some people thrive on low-carb diets, others may experience sleep problems due to the restriction of carbohydrates. Carbohydrates play a role in the production of serotonin, a neurotransmitter that promotes relaxation and sleep.
- High Protein Intake: While protein is essential for health, excessive protein intake, especially close to bedtime, can interfere with sleep. Protein digestion requires energy and can raise body temperature, making it harder to fall asleep.
- Nutrient Deficiencies: Although the carnivore diet can be nutrient-dense, it may also lead to deficiencies in certain nutrients, such as electrolytes (magnesium, potassium) and certain vitamins, which are important for sleep regulation.
- Digestive Issues: Some individuals may experience digestive problems, such as constipation or diarrhea, when starting the carnivore diet. These issues can disrupt sleep and make it difficult to get comfortable.
- Circadian Rhythm Disruption: The timing of meals can influence circadian rhythms. Eating a large meal late at night, especially one high in protein and fat, may disrupt the body's natural sleep-wake cycle.
- Stress and Anxiety: Stress and anxiety often interrupt sleep quality and duration.
Tips for Mitigating Insomnia on the Carnivore Diet
If you're experiencing insomnia on the carnivore diet, here are some tips that may help:
- Optimize Meal Timing: Avoid eating large meals close to bedtime. Try to finish your last meal at least 3-4 hours before going to sleep.
- Balance Macronutrients: While the carnivore diet is primarily protein and fat, experiment with the ratio of these macronutrients. Some people find that slightly increasing fat intake and reducing protein intake in the evening can improve sleep.
- Ensure Adequate Electrolyte Intake: Supplement with electrolytes, especially magnesium and potassium, as needed. These minerals play a crucial role in sleep regulation.
- Prioritize Sleep Hygiene: Practice good sleep hygiene habits, such as maintaining a consistent sleep schedule, creating a relaxing bedtime routine, and optimizing your sleep environment.
- Manage Stress: Implement stress-reducing techniques, such as meditation, yoga, or spending time in nature.
- Consider a Modified Carnivore Diet: Some people find that incorporating small amounts of low-carb vegetables or fruits can improve sleep without compromising the benefits of the carnivore diet.
- Consult with a Healthcare Provider: If insomnia persists, consult with a healthcare provider or registered dietitian to rule out any underlying medical conditions or nutrient deficiencies.
- Choose Meat Wisely: Those refined carbohydrates can spike your blood sugar and lead to type 2 diabetes and obesity. The carnivore diet's emphasis on meat could have you losing sleep if you choose meat that's high in saturated fat. Saturated fat can interfere with your sleep quality by reducing time in deep sleep and causing more sleep disruptions.
