Ketogenic Diet Alert: here’s what can happen to your cholesterol and blood sugar levels

The ketogenic diet, one of the most popular food trends of recent years, has attracted considerable attention for its alleged benefits in weight loss and metabolic health. However, while many individuals enthusiastically embrace this low-carb, high-fat diet, it is essential to understand its potential side effects and health implications, particularly for blood levels of cholesterol and glycemia.

The ketogenic diet, also known as the keto diet, is based on the induction of a metabolic state called ketosis in which the body produces metabolic ketones derived mainly from fats, using them as a primary energy source instead of carbohydrates. This state is achieved by dramatically reducing carbohydrate intake, usually to less than 50 grams per day, and increasing fat and protein intake.

One of the most debated aspects of the ketogenic diet concerns its impact on levels of cholesterol. On the one hand, some studies have suggested that the ketogenic diet can increase LDL cholesterol (low-density lipoprotein), commonly known as “bad cholesterol”. This increase could be attributed to the increased intake of saturated fats, typical of this diet. However, it is important to consider that not all saturated fats are the same, and some studies have suggested that the quality of fat sources in the ketogenic diet could affect the lipid profile differently.

On the other hand, the ketogenic diet was also associated with an increase in HDL cholesterol (high-density lipoprotein), commonly known as “good cholesterol”, which plays a protective role against heart disease. Furthermore, many supporters of the keto diet argue that the relationship between total cholesterol and HDL cholesterol, which is considered a more accurate indicator of cardiovascular risk than the single value of LDL cholesterol, improves with this diet.

However, it is important to note that the effects of the ketogenic diet on lipids can vary considerably from individual to individual. Some people may experience a significant improvement in their lipid profile, while others may see an increase in LDL cholesterol. Consequently, it is crucial to monitor cholesterol levels regularly while adopting this diet and consult a health professional to assess individual risks.

In addition to the effects on cholesterol, the ketogenic diet can also affect levels of glycemia and insulin. Since the diet is extremely low in carbohydrates, it can lead to a significant reduction in glycemia and insulin, which can be beneficial for people with type 2 diabetes or insulin resistance. By reducing carbohydrate intake, it reduces the need for insulin to transport glucose from cells into the blood.

However, it is important to note that the extreme reduction of carbohydrates in the ketogenic diet can also cause some unwanted side effects, such as nutritional ketosis, which can cause nausea, fatigue, and irritability. Additionally, some people may experience problems with constipation or electrolyte imbalances due to the loss of fluids and minerals.

It is important to underline that the ketogenic diet may not be suitable for everyone and may pose risks for some people, especially those who have pre-existing medical conditions or take medications that can be affected by the diet. Before embarking on any significant dietary changes, it is crucial to consult a doctor or dietician to assess your individual situation and discuss potential risks and benefits.

In conclusion, the ketogenic diet can have a significant impact on cholesterol and blood sugar levels, with potential both positive and negative effects. While it may be effective for weight loss and metabolic control in some individuals, it is critical to understand its potential risks and consult a health professional before adopting it. Monitoring cholesterol and blood sugar levels regularly and adapting the diet based on the body’s individual responses is essential to ensure safe and effective health management.
