The carnivore diet, an extreme form of a low-carbohydrate diet, has gained popularity for its potential benefits, including weight loss and blood sugar stabilization. However, like any restrictive diet, it carries potential risks, including hypoglycemia. This article explores the relationship between the carnivore diet and hypoglycemia, examining the underlying mechanisms, potential benefits, and important considerations.
Understanding the Carnivore Diet
The carnivore diet is a restrictive dietary approach that consists exclusively of animal products, such as meat, fish, eggs, and sometimes dairy. It eliminates all plant-based foods, including fruits, vegetables, grains, legumes, and nuts. Proponents of the diet claim various health benefits, including weight loss, improved blood sugar control, reduced inflammation, and better digestive health.
What is Hypoglycemia?
Hypoglycemia, or low blood sugar, occurs when glucose levels in the blood drop below normal, typically below 70 mg/dL (3.9 mmol/L). Glucose is the primary source of energy for the body's cells, particularly the brain. When blood sugar levels fall too low, the brain may not receive enough fuel to function properly, leading to a range of symptoms.
Symptoms of Hypoglycemia
Symptoms of hypoglycemia can vary from person to person and may include:
- Lightheadedness and dizziness
- Fatigue
- Hunger
- Shakiness
- Difficulty concentrating
- Irregular or increased heart rate
- Sweating
- Confusion
- Irritability
- Loss of consciousness (in severe cases)
Nocturnal hypoglycemia, which occurs during sleep, may manifest as nightmares, night sweats, fatigue upon waking, or a morning headache.

Hypoglycemia and the Carnivore Diet: Exploring the Connection
While the carnivore diet is often praised for its potential to stabilize blood sugar levels, it can also increase the risk of hypoglycemia in certain individuals. Several factors contribute to this risk:
Reduced Carbohydrate Intake
The most significant factor is the extremely low carbohydrate intake. Carbohydrates are the body's primary source of glucose. By eliminating them almost entirely, the carnivore diet forces the body to rely on alternative energy sources, such as fat and protein.
Liver Glycogen Depletion
When carbohydrate intake is restricted, the liver's glycogen stores (stored glucose) become depleted. This can impair the body's ability to release glucose into the bloodstream when blood sugar levels drop, increasing the risk of hypoglycemia.
The Role of Gluconeogenesis
In the absence of carbohydrates, the body can produce glucose through a process called gluconeogenesis, which involves converting protein and fat into glucose. However, this process may not be sufficient to maintain stable blood sugar levels, especially during periods of increased energy demand, such as exercise.
Impact on Insulin Sensitivity
The carnivore diet may improve insulin sensitivity in some individuals, which means that the body requires less insulin to transport glucose into cells. While this can be beneficial for people with insulin resistance or type 2 diabetes, it can also increase the risk of hypoglycemia if insulin levels are not properly managed.

Alcohol Consumption
Alcohol can further exacerbate the risk of hypoglycemia in individuals following a carnivore diet. Alcohol metabolism can interfere with gluconeogenesis, reducing the liver's ability to produce glucose and maintain blood sugar levels.
Case Study: Hypoglycemia on a Ketogenic Diet
A 69-year-old woman with a history of psoriatic arthritis, Sjogren disease, leukocytoclastic vasculitis, asthma, and anxiety disorder, who had been following a ketogenic diet for nearly one year, presented with malaise, sugar cravings, and mental fogginess. After consuming alcoholic beverages, she was admitted to the hospital with hypoglycemia, with a blood glucose level of 39 mg/dL. Her beta-hydroxybutyrate levels were elevated, and her insulin and C-peptide levels were low, consistent with starvation ketosis. This case demonstrates that prolonged adherence to a ketogenic diet, combined with alcohol intake, can disrupt normal glucose homeostasis and lead to significant hypoglycemia.
Potential Benefits of the Carnivore Diet for Blood Sugar Control
Despite the risk of hypoglycemia, the carnivore diet may offer potential benefits for blood sugar control in certain individuals, particularly those with insulin resistance or type 2 diabetes.
Reduced Glucose Spikes
By eliminating carbohydrates, the carnivore diet can prevent rapid spikes in blood sugar levels after meals. This can help improve glycemic control and reduce the need for medication in some individuals with diabetes.
Improved Insulin Sensitivity
Some studies suggest that low-carbohydrate diets, including the carnivore diet, can improve insulin sensitivity. This means that the body requires less insulin to transport glucose into cells, which can help lower blood sugar levels and reduce the risk of hyperglycemia (high blood sugar).

Weight Loss
The carnivore diet can promote weight loss by increasing satiety and reducing calorie intake. Weight loss can, in turn, improve insulin sensitivity and blood sugar control.
Who Should Avoid the Carnivore Diet?
The carnivore diet is not suitable for everyone and should be avoided by certain individuals, including:
- People with kidney disease: The high protein content of the carnivore diet can put a strain on the kidneys.
- People with gout: The carnivore diet can increase uric acid levels, which can trigger gout attacks.
- Pregnant and breastfeeding women: The carnivore diet may not provide all the nutrients needed for a healthy pregnancy and breastfeeding.
- Children and adolescents: The carnivore diet may not provide the necessary nutrients for growth and development.
- People with a history of eating disorders: The restrictive nature of the carnivore diet can be triggering for individuals with a history of eating disorders.
- Individuals at risk for heart disease: A diet high in saturated fat may increase the risk of heart disease.
Important Considerations for Those Considering the Carnivore Diet
If you are considering the carnivore diet, it is essential to consult with a healthcare professional or registered dietitian to assess your individual needs and risks. Here are some important considerations:
Monitor Blood Sugar Levels Regularly
If you have diabetes or are at risk of hypoglycemia, it is crucial to monitor your blood sugar levels regularly, especially when starting the carnivore diet.
Adjust Medications as Needed
If you take medications for diabetes, you may need to adjust your dosage under the guidance of your healthcare provider to prevent hypoglycemia.
Stay Hydrated
Dehydration can increase the risk of hypoglycemia. Drink plenty of water throughout the day.
Be Aware of Hypoglycemia Symptoms
Learn to recognize the symptoms of hypoglycemia and take prompt action if they occur.
Carry a Source of Fast-Acting Carbohydrates
Always carry a source of fast-acting carbohydrates, such as glucose tablets or fruit juice, to treat hypoglycemia if it occurs.
Avoid Alcohol
Limit or avoid alcohol consumption, as it can increase the risk of hypoglycemia.
Ensure Adequate Nutrient Intake
The carnivore diet is restrictive and may not provide all the nutrients your body needs. Consider taking supplements to address potential nutrient deficiencies.
Listen to Your Body
Pay attention to how you feel and adjust your diet as needed. If you experience persistent symptoms of hypoglycemia or other health problems, discontinue the carnivore diet and consult with a healthcare professional.
The Carnivore Diet and Athletes
Christina, an avid athlete, struggled with severe hypoglycemia while following a high-carbohydrate diet recommended for athletes. After rediscovering red meat and adopting a carnivore diet, her hypoglycemia disappeared, and she hasn't had a single hypoglycemic episode in four and a half years.
Alternative Dietary Approaches
For people with diabetes, The DASH diet, or Dietary Approaches to Stop Hypertension, is a more beneficial diet. The DASH diet not only lowers the risk of developing type 2 diabetes, but it can also decrease insulin resistance in people with diabetes as well. Itâs high in fruits and vegetables, whole grains, and emphasizes leaner protein choices, such as fish and poultry, low fat dairy, and beans. Foods higher in saturated fats and added sugars are limited. Recent research found that a low fat vegan diet could improve type 2 diabetes markers in people who havenât developed diabetes. This further suggests the importance of plant-based foods for diabetes prevention and management. The Mediterranean diet plan has an increasing body of research to support its effectiveness for diabetes prevention and managing type 2 diabetes.
