Keto Diet: Balancing Blood Sugar Levels

The ketogenic diet is a popular, low-carb approach to weight loss and blood sugar control. The diet aims to deprive the body of carbohydrates, leading to a metabolic state called ketosis, where the body uses ketones for energy instead of glucose. While on the keto diet, blood glucose readings trend downward, and average glucose levels typically fall between 70 and 90 mg/dL.

This article will explore how long it takes for blood sugar levels to normalise on the keto diet and the factors that can influence this process. We will also discuss the potential benefits and drawbacks of maintaining ketosis for blood sugar management.

Ketogenic diets can help manage blood sugar levels

Ketogenic diets are a popular way to manage blood sugar levels and can be a great tool for enhancing metabolic flexibility, reducing insulin levels, managing glucose levels, preventing neurological diseases, and treating migraines.

When we eat, our pancreas releases insulin to store away excess energy as fat. When we fast, our body taps into its stored energy reserves.

Ketogenic diets limit carbohydrate intake, which deprives the body of glucose from external food sources. This forces the body to switch from using glucose for energy to breaking down glycogen (stored glucose) and eventually breaking down fats for energy, a process known as ketosis.

During ketosis, the body breaks down fats for energy, releasing ketones that fuel the body's cells and tissues. Ketosis is a normal process that can occur during exercise or when following a ketogenic diet.

Benefits of ketogenic diets for blood sugar management

Lower glucose trends

Carbohydrates have the most significant influence on glucose levels. Therefore, following a ketogenic diet with minimal to no carbohydrates will help keep your glucose levels more stable and steady.

Elevated fasting glucose levels

Elevated fasting glucose levels, also known as "glucose sparing," is a common adaptation for individuals who have been on a strict ketogenic diet for a prolonged period. This is the body's way of ensuring that glucose is present for organs that require it, and current research suggests it is not necessarily a negative adaptation.

High glucose spikes from small amounts of carbs

Ketogenic diets help lower insulin levels. However, a common trend observed is slightly higher glucose responses to small amounts of carbohydrates. This is because individuals on a very low-carb diet may have lower insulin sensitivity compared to those consuming more carbs.

Personalized nutrition insights

Testing blood glucose levels while on a ketogenic diet can provide valuable insights into how your body responds to specific foods. This can help you make informed decisions about your diet and identify trigger foods that cause glucose spikes.

Factors to consider

It is important to note that ketogenic diets are not suitable for everyone and should be approached with caution, especially for individuals with Type 1 diabetes, as high ketone levels can be dangerous and put them at risk of diabetic ketoacidosis (DKA).

Additionally, ketogenic diets can be challenging to stick to due to their restrictive nature. It is always recommended to speak with a healthcare provider before making any significant dietary changes.

Ketogenic diets can be a powerful tool for managing blood sugar levels and improving metabolic health. By limiting carbohydrates, the body shifts to burning fats for energy, resulting in more stable glucose levels and improved insulin sensitivity. However, it is important to monitor your health and work with a healthcare professional to ensure the diet is suitable for your individual needs.

Blood sugar levels can be tested at home

Blood sugar monitoring is an important aspect of managing diabetes, especially for those with type 1 diabetes or those taking insulin. Testing your blood sugar levels at home can be done with a glucose meter and test strips or a continuous glucose monitor (CGM) system. Here are the steps you can take to test your blood sugar levels at home:

Prepare for the Test

Ensure you have all the necessary items within reach before starting. Timing is crucial. Clean the area where you will prick your finger with soap and water, and completely dry the skin before pricking. Do not use an alcohol pad or swab to clean the skin, as alcohol is not effective in removing sugar residue.

Perform the Test

You can purchase a testing kit from a pharmacy without a prescription. Your healthcare provider can help you choose the right kit, set up the meter, and teach you how to use it. The test itself is simple: prick your finger with a small needle (lancet) to draw a drop of blood, then place the blood drop on a special strip that measures your glucose level. The meter will display your blood sugar results as a digital reading. If you have poor vision, talking glucose meters are available.

Record and Track Your Results

It is important to keep a record of your blood sugar levels, as this will help you and your healthcare provider manage your diabetes effectively. Record your blood sugar level, the amount of carbohydrates consumed, the type and dose of diabetes medication, the type and duration of exercise, and any unusual factors such as stress, different foods, or illness. You can use a logbook or an app on your smartphone to track your levels. Most glucose meters can store hundreds of readings, and some even allow you to save the results to your computer or smartphone.

Understand Optimal Blood Sugar Levels

According to the Mayo Clinic, a fasting blood sugar level under 100 milligrams per deciliter is considered healthy. Your blood sugar level after consuming food (even pure sugar) should not exceed 125 milligrams per deciliter, as this is an indication of prediabetes. However, it's important to remember that everyone's target range for blood sugar levels is unique and can change throughout their life. Work with your healthcare provider to determine your ideal target range and monitor your levels regularly to ensure you stay within that range.

High blood sugar levels can be dangerous

High blood sugar levels, also known as hyperglycaemia, can be dangerous and lead to serious health problems if left untreated. While the odd mild episode is usually nothing to worry about, high blood sugar levels that become very high or persist for long periods can be life-threatening.

Diabetic Ketoacidosis (DKA)

DKA is a condition caused by the body needing to break down fat as a source of energy because there is not enough insulin in the body. This can lead to a diabetic coma and is more common in people with type 1 diabetes. Symptoms of DKA include:

• Stiff or achy muscles
• Extreme thirst or a very dry mouth
• Having to pee too often
• Breath that smells like fruit

Hyperosmolar Hyperglycaemic State (HHS)

HHS is a severe condition where the body tries to get rid of excess sugar. It is caused by the body making insulin, but the insulin not working properly. HHS mainly affects people with type 2 diabetes and can lead to life-threatening dehydration and coma. Symptoms of HHS include:

• Extreme thirst that may later go away
• Warm, dry skin that doesn’t sweat
• Sleepiness or confusion
• Weakness on one side of your body

Long-Term Complications

Even if they are not treated as a medical emergency, high blood sugar levels can lead to long-term complications, including:

• Cardiovascular disease
• Nerve damage (neuropathy)
• Kidney damage or failure
• Damage to the blood vessels of the retina (diabetic retinopathy) that could lead to blindness
• Feet problems caused by damaged nerves or poor blood flow, which can lead to serious skin infections, ulcerations and, in severe cases, amputation
• Bone and joint problems
• Teeth and gum infections

What to Do if You Have High Blood Sugar Levels

If you have high blood sugar levels, it is important to seek medical advice and make changes to your lifestyle to bring them down to a healthy range. This may include:

• Changing your diet to avoid foods that cause your blood sugar levels to rise, such as cakes or sugary drinks
• Drinking plenty of sugar-free fluids
• Exercising more often – gentle, regular exercise such as walking can help lower blood sugar levels, especially if it helps with weight loss
• Adjusting your insulin dose, if you use insulin – your diabetes care team can give you specific advice about this
• Monitoring your blood sugar levels more closely, or testing for ketones in your blood or urine

Ketogenic diets can help prevent Type 2 Diabetes

The ketogenic diet is a very low-carb, high-fat, and moderate protein diet. It involves limiting carbohydrate intake to a range of 20-50 grams per day for a 2,000-calorie diet, which is typically 10% of total calories. This restriction on carbohydrates forces the body to break down fats for energy, producing an energy source known as ketones. This process of burning body fat is called ketosis.

The ketogenic diet has been shown to be very effective in achieving two common goals of diabetes control: lowering blood glucose levels and reducing weight. By keeping blood glucose levels at a low but healthy level, the diet helps to manage blood sugar and prevent large fluctuations, which is especially beneficial for those with prediabetes or at risk of developing Type 2 Diabetes.

The body's primary source of energy comes from carbohydrates, which are broken down into glucose. However, the ketogenic diet limits this source of glucose, causing the body to switch to glycogen (stored glucose) and then to fat for energy. This reduces the body's demand for insulin, which is beneficial for people with Type 1 and Type 2 Diabetes, as insulin helps move glucose from the blood into cells.

Benefits of the Ketogenic Diet

The ketogenic diet not only helps with blood glucose management and weight loss but also has additional benefits, including:

• Reducing high blood pressure
• Lowering triglyceride levels
• Raising HDL cholesterol levels, which is good for heart health
• Improving mental performance

Side Effects and Safety

Starting a ketogenic diet can result in short-term side effects, including "keto-flu," a group of symptoms resembling the flu, as well as changes in bowel habits, leg cramps, and loss of energy. These side effects are usually temporary and last a few days to a few weeks.

There is a lack of long-term studies on the safety and effectiveness of ketogenic diets, and some people may find it challenging to maintain due to its restrictive nature. It is important to consult a healthcare professional before starting this or any other diet, especially for those with specific health conditions or taking certain medications.

The ketogenic diet can be a powerful tool for managing blood sugar and preventing Type 2 Diabetes. However, it should be approached with caution and under the guidance of a healthcare professional to ensure safety and effectiveness for each individual.

Ketogenic diets can help treat Type 2 Diabetes

The ketogenic diet has been hailed as a potential treatment for Type 2 Diabetes. This is because the diet is high in fat and low in carbohydrates, which can change the way the body stores and uses energy, thus easing diabetes symptoms.

The ketogenic diet was created in the 1920s as a treatment for epilepsy. On this diet, the body converts fat, instead of sugar, into energy. The body achieves a state of ketosis, where it burns fat rather than carbohydrates. This diet can help manage blood glucose (sugar) levels and reduce the need for insulin.

The ketogenic diet typically involves eating less than 50 grams of carbohydrates per day, while increasing fat and moderating protein intake. Foods include low-carb vegetables (like leafy greens and broccoli), eggs, poultry, beef, pork, avocados, olive oil, nuts, seeds, fish, shellfish, and unsweetened dairy products.

The ketogenic diet may help people with Type 2 Diabetes to manage their blood sugar levels and reduce their need for insulin. It may also aid weight loss, which is beneficial for diabetes and high blood sugar levels. The diet may also lead to lower blood pressure, improved insulin sensitivity, and improved cholesterol levels.

The ketogenic diet is highly restrictive, and some people may find it hard to follow in the long term. It can also lead to short-term side effects, such as "keto-flu", constipation or diarrhea, leg cramps, and loss of energy. There may also be an increased risk of nutrient deficiencies, kidney stones, dyslipidemia, and fatty liver disease.

The American Diabetes Association (ADA) does not recommend one diet over another for people with Type 2 Diabetes. Experts caution that there is a lack of evidence about the long-term safety and effectiveness of the ketogenic diet, and more studies are needed. It is important for individuals to consult with their healthcare team before starting any new diet, especially when managing a condition such as Type 2 Diabetes.
