The ketogenic diet is a popular eating plan that involves eating low-carb, high-fat foods. While it is often touted as a weight-loss solution, some people also use it to manage blood sugar levels and improve their overall health. For people with diabetes, the keto diet may be a way to control blood sugar levels since it restricts carbohydrates, which can impact blood sugar. However, there are some potential risks and side effects associated with the keto diet, especially for people with high cholesterol.
What You'll Learn
The keto diet can help manage blood sugar levels in people with diabetes
The keto diet is a popular, low-carb, high-fat diet that has been found to help people with diabetes manage their blood sugar levels. The diet restricts carbohydrates, which can impact blood sugar, and forces the body to break down fats for energy instead. This can help to keep blood sugar levels at a low but healthy level and improve several markers of health in people with diabetes.
The keto diet is short for the ketogenic diet, a popular diet that involves restricting total carbohydrate intake to 20-50 grams per day. This forces the body to shift from using glucose as its main source of energy to using ketone bodies, a type of chemical formed from the breakdown of fat. This metabolic state is known as ketosis.
For people with diabetes, the keto diet can help manage blood sugar levels by allowing the body to maintain blood sugar at a low but healthy level. The lower intake of carbohydrates may help to minimise large fluctuations in blood sugar, which can positively impact several clinical markers of blood sugar control. Research has found that the keto diet can help to control blood sugar levels significantly in people with diabetes and may even aid in the reversal of prediabetes.
The keto diet has been found to offer several potential benefits for people with diabetes, including:
- Improved glycemic (or blood sugar) control
- Improved insulin resistance
- Reduced need for insulin
- Increased heart-healthy HDL ("good") cholesterol levels
- Improved cognitive function
- Weight loss
While the keto diet has shown promising results for people with diabetes, there are some risks and considerations to keep in mind. The keto diet is highly restrictive, which can make it challenging to maintain in the long term. It may also lead to an increased risk of developing diabetic ketoacidosis (DKA), a potentially life-threatening complication that occurs when the body doesn't produce enough insulin. Additionally, people with diabetes and a history of heart disease should be cautious when starting a keto diet as it can lead to higher levels of cholesterol, which can have adverse effects.
It's important to consult with a healthcare professional before starting the keto diet, especially for those with diabetes, to ensure it is a safe and suitable option for their individual needs.

The keto diet can lead to weight loss
The keto diet is a popular eating plan that has been shown to be effective for weight loss. It involves a drastic reduction in carbohydrate intake, with only 20-50 grams of carbohydrates consumed per day. This forces the body to shift from using glucose as its main energy source to using ketone bodies, which are produced from the breakdown of fats. This shift in energy sources is known as ketosis, and it is considered a safe metabolic state for most people.
The keto diet is particularly beneficial for people with type 2 diabetes, as it helps them maintain blood sugar levels at a low but healthy level. By reducing carbohydrate intake, the diet minimises large fluctuations in blood sugar, which can positively impact several clinical markers of blood sugar control. Additionally, the keto diet has been found to improve fasting blood sugar and insulin levels and may even lead to a reduction or elimination of diabetes medications.
However, it is important to note that the keto diet is not a magic cure and should be approached with caution. It is incredibly restrictive and difficult to maintain in the long term. It can also lead to an increased risk of developing diabetic ketoacidosis, a potentially life-threatening complication that occurs when the body doesn't produce enough insulin. Other possible dangers include hypoglycaemia, which is dangerously low blood sugar, and dyslipidemia, an imbalance of lipids in the blood.
Despite these risks, the keto diet has been shown to be effective for weight loss, especially for people with type 2 diabetes. A 2018 study published in *Diabetes Therapy* found that a group of 262 people with type 2 diabetes were able to reduce their weight and A1C levels, and some were even able to reduce or eliminate their diabetes medication after one year of following a ketogenic diet.
For those considering the keto diet, it is important to consult with a healthcare professional to ensure it is suitable for your individual needs and health status. Additionally, combining the diet with regular exercise is recommended for optimal health benefits. While the keto diet may not be sustainable long-term for everyone, it can be a powerful tool for weight loss and improved health, particularly for those with type 2 diabetes.

The keto diet can be difficult to maintain long-term
The keto diet is also incredibly strict, as it requires a person to stay below a certain number of carbs per day, typically less than 50 grams. This can be challenging, as it involves a major shift in eating habits, especially for those who are used to eating more carbs than fat.
The restrictive nature of the keto diet can make it hard to follow for an extended period. People will likely find it more beneficial to adopt a moderate diet and lifestyle program that is more sustainable in the long term.
Additionally, there is a lack of evidence regarding the long-term safety and effectiveness of the keto diet. Healthcare professionals have called for more primary studies and evidence before recommending this diet for the management of diabetes or high cholesterol.
The keto diet may also lead to some adverse side effects, including short-term symptoms such as "keto flu," constipation, and diarrhea, as well as potential long-term effects like the development of kidney stones and an increased risk of nutrient deficiencies.
Furthermore, the keto diet may not be suitable for everyone, especially those with certain health conditions. For instance, it is not recommended for pregnant or lactating individuals, those with a history of eating disorders, or people with specific disorders of fat metabolism.
Overall, while the keto diet may offer some potential benefits for diabetics and individuals with high cholesterol, it can be challenging to maintain in the long term due to its restrictive nature, potential side effects, and lack of long-term evidence.

The keto diet may increase the risk of certain health complications
Firstly, the keto diet is associated with an increased risk of kidney problems. High-fat animal foods, such as eggs, meat, and cheese, are staples of the keto diet, and consuming large amounts of these foods can lead to a higher risk of kidney stones. The keto diet may also overload the kidneys and lead to protein overload.
Secondly, the keto diet can cause digestive issues and constipation due to its low fiber content. The diet restricts high-carb fruits, starchy vegetables, whole grains, and beans, which are rich sources of fiber. As a result, individuals on the keto diet may experience digestive discomfort and constipation.
Thirdly, the keto diet may lead to nutrient deficiencies, particularly of vitamins and minerals. The diet restricts several nutrient-dense foods, including fruits, whole grains, and legumes, and may not provide sufficient amounts of calcium, vitamin D, magnesium, and phosphorus.
Additionally, the keto diet has been linked to an increased risk of heart disease due to its high saturated fat content. The diet may also cause liver problems, especially for those with existing liver conditions, as the body has to metabolize a large amount of fat.
Furthermore, the keto diet may result in fuzzy thinking and mood swings, as the brain functions optimally with glucose from healthy carbohydrates as its energy source. Low-carb diets, like keto, may lead to confusion and irritability.
Lastly, the keto diet could potentially increase the risk of bone health issues, with some studies linking the diet to decreased bone strength and bone mineral density loss.
It is important to consult a healthcare professional before starting the keto diet, as it may not be suitable for individuals with certain medical conditions, including kidney, heart, or bone ailments.

The keto diet may have benefits for people with prediabetes
The keto diet has been found to be beneficial for people with prediabetes. Prediabetes is a warning stage before diabetes, and the keto diet may help to reverse this condition. The keto diet is a low-carb, high-fat diet that restricts carbohydrates, which can impact blood sugar. By reducing carbohydrate intake, the keto diet can help to control blood sugar levels and improve lipids in the blood.
People with prediabetes may experience improved fasting blood sugar and insulin levels, as well as a reduction or elimination of diabetes medications, by following the keto diet. Additionally, the keto diet can aid in weight loss, which can further improve insulin resistance.
It is important to note that the keto diet is incredibly restrictive and may be difficult to maintain long-term. It eliminates or significantly reduces the number of carbs a person consumes, and can lead to an increased risk of developing diabetic ketoacidosis, hypoglycemia, and dyslipidemia. Before starting the keto diet, it is recommended to consult a healthcare professional to discuss the benefits and risks based on individual health status.
Some alternative diets that can also help manage blood sugar levels include the Mediterranean diet and the Atkins diet. These diets offer more variety in food choices compared to the keto diet and can be easier to maintain in the long term. The Mediterranean diet, in particular, has been found to be as effective as the keto diet in controlling blood glucose levels and aiding weight loss.
While the keto diet may have benefits for people with prediabetes, it is important to individualize diet plans based on personal eating habits, preferences, and health targets such as blood sugar levels and weight. Consulting with a healthcare professional or a registered dietitian can help determine the most suitable diet plan for managing prediabetes.
