The ketogenic diet, known as "keto," is a popular dietary approach that involves drastically reducing carbohydrate intake and increasing fat consumption. This metabolic shift forces the body to burn fat for fuel, leading to weight loss and other potential benefits. While keto can be effective for some, it's essential to understand its potential effects on blood sugar levels, especially for individuals with diabetes or those prone to hypoglycemia (low blood sugar).
Understanding Hypoglycemia
Hypoglycemia occurs when blood glucose levels drop below the normal range, typically defined as lower than 70 milligrams per deciliter (mg/dL). This can be a dangerous condition, particularly for people with diabetes, as it can lead to symptoms like weakness, shaking, dizziness, confusion, and even seizures.
Symptoms of Hypoglycemia
Recognizing the symptoms of hypoglycemia is crucial for prompt treatment. Common symptoms include:
- Weakness or shaking
- Moist skin or sweating
- Fast heartbeat
- Dizziness
- Confusion
- Unsteadiness
- Nightmares, bad dreams, or restless sleep
- Blurred vision
- Headaches and seizures
Causes of Hypoglycemia on Keto
While the keto diet can help lower blood sugar levels in some individuals, it can also increase the risk of hypoglycemia, especially if certain factors are not carefully managed.
- Medication Imbalance: Individuals with diabetes who are taking insulin or other blood sugar-lowering medications may experience hypoglycemia if their medication dosage is not properly adjusted to account for the reduced carbohydrate intake on the keto diet.
- Restrictive Eating: The keto diet is highly restrictive, and it can be challenging to maintain in the long term. Yo-yo dieting and inconsistent eating patterns can disrupt blood sugar control and increase the risk of hypoglycemia.
- Nutrient Deficiencies: Avoiding certain food groups on keto can lead to nutrient deficiencies, which may further impact blood sugar regulation.
- Alcohol Consumption: Alcohol can interfere with glucose production in the liver, potentially leading to hypoglycemia, especially when combined with a ketogenic diet.
- Prolonged Fasting: Long periods without eating can cause ketotic hypoglycemia, particularly in young children, as their bodies have higher energy demands and lower reserves of stored glucose.
- Underlying Medical Conditions: In rare cases, hypoglycemia may be a sign of an underlying medical condition, such as an insulinoma (a tumor that produces insulin).
Strategies for Managing Low Blood Sugar on Keto
If you're following a keto diet and experiencing symptoms of hypoglycemia, it's essential to take prompt action to raise your blood sugar levels. Here are some strategies to consider:

1. Quick-Acting Carbohydrates
For blood sugar levels below 55 mg/dL, rapid-acting liquid carbohydrates without fiber, fat, or protein are recommended. Examples include:
- 100% grape juice
- Honey or maple syrup
For less severe hypoglycemia (blood sugar levels between 55 and 70 mg/dL), consider these options:
- Raisins
- Grapes
- Medjool dates
- Applesauce
- Bananas
- Pineapple
2. Balanced Snacks
If your blood sugar is trending lower but still above 70 mg/dL, choose snacks that combine carbohydrates with protein and fat for sustained energy.
- Peanut butter and crackers
- Nuts and seeds
- Cheese and vegetables
3. Monitor Blood Sugar Levels Regularly
Regular blood sugar monitoring is crucial for individuals on the keto diet, especially those with diabetes. This helps identify patterns and potential triggers for hypoglycemia, allowing for timely adjustments to diet or medication. A continuous glucose monitor (CGM) can be particularly helpful for tracking blood sugar levels in real-time and identifying nocturnal hypoglycemia (low blood sugar during sleep).
4. Adjust Medications
If you have diabetes and are taking insulin or other blood sugar-lowering medications, work closely with your doctor to adjust your medication dosage as needed. The keto diet can significantly impact blood sugar levels, so medication adjustments are often necessary to prevent hypoglycemia.

5. Consult with a Healthcare Professional
Before starting a keto diet, especially if you have diabetes or a history of hypoglycemia, consult with your doctor or a registered dietitian. They can help you assess the potential risks and benefits of the keto diet for your individual needs and provide guidance on how to manage blood sugar levels effectively.
6. Consider Nutrient Supplementation
The keto diet can be restrictive, potentially leading to nutrient deficiencies. Talk to your doctor about whether vitamin and mineral supplements are needed. Some nutrients that may be beneficial for blood sugar control include:
- Chromium: Improves insulin sensitivity and glucose tolerance.
- Magnesium: Plays a crucial role in maintaining healthy blood sugar levels.
- Alpha-lipoic acid: Improves insulin sensitivity and glucose utilization.
7. Be Mindful of Alcohol Consumption
Alcohol can interfere with glucose production in the liver and increase the risk of hypoglycemia, especially when combined with a ketogenic diet. Limit alcohol consumption or avoid it altogether.
8. Avoid Prolonged Fasting
Avoid long periods without eating, especially if you are prone to hypoglycemia. Ensure regular meals and snacks to maintain stable blood sugar levels.
9. Address Underlying Medical Conditions
If you experience recurrent hypoglycemia, even with careful diet and lifestyle management, your doctor may recommend further testing to rule out any underlying medical conditions.

Ketotic Hypoglycemia
Ketotic hypoglycemia is a specific type of hypoglycemia that occurs when low blood sugar levels are accompanied by high levels of ketones. It is most common in young children, often when they have not eaten for a long period or when they are ill.
Symptoms of Ketotic Hypoglycemia
Children with ketotic hypoglycemia may experience symptoms such as:
- Irritability
- Tiredness
- Shakiness
Treatment of Ketotic Hypoglycemia
The primary treatment for ketotic hypoglycemia is to raise blood sugar levels by giving the child something containing sugar, such as fruit juice or soda. In some cases, a doctor may recommend giving glucose directly into the bloodstream.
Keto and Diabetes: Pros and Cons
While the keto diet can be effective for managing Type 2 diabetes by lowering blood sugar and promoting weight loss, it's not right for everyone. Here's a look at the pros and cons:
Pros
- Effective for blood sugar management
- Effective for weight loss
- May reduce dependence on diabetes medication and insulin (when followed in close consultation with a doctor)
Cons
- Increased risk of hypoglycemia, especially if medication and insulin are not in balance with eating patterns
- Difficult to stick to in the long term
- Potential for nutrient deficiencies
- May cause constipation due to low fiber intake
A Word of Caution: Ketoacidosis
It's important to distinguish between ketosis and ketoacidosis. Ketosis is the desired metabolic state on the keto diet, where the body burns fat for fuel. Ketoacidosis, on the other hand, is a dangerous condition where ketones build up excessively, turning the blood acidic. This is more common in people with Type 1 diabetes when blood sugar levels are too high and insulin levels are inadequate, but it can also happen in people with Type 2 diabetes. Symptoms of ketoacidosis include excessive thirst, frequent urination, confusion, weakness, and fatigue. If you think you might be developing ketoacidosis, seek immediate medical attention.
Alternative Dietary Approaches
If the keto diet is not suitable for you, consider other carbohydrate-controlled eating patterns, such as the Mediterranean diet. This diet emphasizes fruits and vegetables, whole grains, beans, nuts, and moderate amounts of lean poultry, fish, and dairy.
