Keto Diet: A Potential Cure For Diabetes?

The ketogenic diet has been linked to improvements in insulin sensitivity and higher rates of weight loss, which are both positive factors in managing type 2 diabetes. Lowering carb intake induces a metabolic state known as ketosis, through which the body produces ketones that burn fat for energy instead of carbohydrates.

The keto diet is a low-carb, high-fat dietary regimen. It was initially created in the 1920s as a treatment for epilepsy, but the effects of this eating pattern are also being studied for type 2 diabetes.

The ketogenic diet may improve blood glucose (sugar) levels while also reducing the need for insulin. However, the diet does come with risks. It is important to discuss it with a doctor before making drastic dietary changes.

The keto diet may help manage blood sugar levels

The ketogenic (keto) diet is a high-fat, low-carbohydrate diet that has been linked to improvements in insulin sensitivity and higher rates of weight loss. Lowering carb intake induces a metabolic state known as ketosis, where the body produces ketones that burn fat for energy instead of carbohydrates. This can be beneficial for people with type 2 diabetes as it helps maintain blood sugar levels at a low but healthy level, minimising large fluctuations in blood sugar.

The keto diet typically involves limiting carbohydrate intake to 20-50 grams per day and deriving 70% of calories from fat. This forces the body to break down fats for energy instead of carbohydrates. The diet includes foods such as low-carb vegetables, eggs, meat, fish and shellfish, avocados, olive oil, nuts, seeds, and unsweetened dairy products.

By limiting carbohydrate intake, the keto diet helps to manage blood sugar levels by reducing large fluctuations in blood sugar. This is particularly beneficial for people with type 2 diabetes, as their bodies struggle to effectively use carbohydrates, leading to high blood sugar levels. The keto diet can also lead to a reduced need for anti-diabetic medication and improved insulin sensitivity.

Some studies have shown that the keto diet can improve blood glucose control and aid weight loss in people with type 2 diabetes. A 2008 study found that participants who followed the keto diet saw greater improvements in glycemic control and medication reduction compared to those on a low-glycemic diet. Similarly, a 2013 review reported that the keto diet led to more significant improvements in blood sugar control, weight loss, and discontinued insulin requirements than other diets. However, a 2017 study found that the keto diet may increase the risk of hypoglycaemia and dyslipidaemia, and there is limited evidence on the long-term safety and effectiveness of the keto diet for people with diabetes.

The restrictive nature of the keto diet can make it difficult to follow long-term. Additionally, there is a risk of developing kidney stones and nutrient deficiencies due to the restriction of certain food groups. The keto diet may also increase the risk of cardiovascular disease due to a buildup of fats in the arteries, especially in people with diabetes who already have an increased risk of cardiovascular disease. Therefore, it is important for people with diabetes to consult a healthcare professional before starting the keto diet and carefully monitor blood sugar and ketone levels to ensure they remain within a safe range.

The keto diet may reduce the need for insulin

The ketogenic diet is a high-fat, moderate protein, and very low-carbohydrate diet. It is well-known that carbohydrates raise insulin levels because you need insulin to metabolizesection carbssection carbs. The ketogenic diet minimizes insulin production by restricting both carbs and protein.

The ketogenic diet is an ultra-low-carb, very high-fat diet that involves a drastic reduction in carbohydrate intake. The diet keeps carbs as low as possible and supplies just enough protein to meet your needs, but not more.這 means that the diet minimizes insulin production by reducing both protein and carbs.

Eating a keto diet significantly reduces fasting insulin and postprandial insulin (insulin levels right after a meal). In patients with diabetes who rely on outside insulin, a ketogenic diet reduces the need for insulin. Insulin resistance improves promptly for most people when they begin a ketogenic diet. The effect appears to be attributable to the ketones per se, not just the reduced intake of carbohydrates.

A 2022 review of randomized clinical trials found little evidence to support keto diets for the long-term management of type 2 diabetes. However, a 2020 meta-analysis found that the ketogenic diet improved lipid metabolism and reduced fasting blood glucose levels in patients with type 2 diabetes.

Overall, the ketogenic diet may reduce the need for insulin in people with diabetes, but more long-term studies are needed to confirm these effects.

The keto diet may help with weight loss

The ketogenic (keto) diet is a high-fat, low-carbohydrate diet that can help people with type 2 diabetes manage their blood sugar levels and lose weight. The diet was originally created in the 1920s as a treatment for epilepsy, but its potential benefits for people with type 2 diabetes are now being explored.

The keto diet works by forcing the body to use fat, rather than carbohydrates or glucose, as its primary energy source. This metabolic state is known as ketosis, where the body produces ketones that burn fat for energy.

The keto diet can aid weight loss by reducing the body's intake of carbohydrates, which can cause blood sugar spikes and are often high in calories. By limiting carbs, the body is forced to burn fat for energy, which can lead to weight loss.

The keto diet focuses on consuming foods that are high in healthy fats, such as:

• Olives and olive oil
• Nuts and nut butters
• Avocados
• Fatty fish, such as salmon and mackerel
• Eggs
• Meat, such as poultry, beef, and pork
• Dairy, such as cheese, butter, and cream
• Low-carb vegetables, such as leafy greens and broccoli

While the keto diet has shown promising results for weight loss and blood sugar management in people with type 2 diabetes, it also comes with some potential risks. One concern is the high intake of saturated fats, which can increase the risk of cardiovascular disease.

Additionally, restricting carbohydrates too much can lead to low blood sugar, or hypoglycemia, especially if medication dosage is not adjusted accordingly. There is also a rare risk of developing diabetic ketoacidosis (DKA), a dangerous condition that can occur if ketone levels get too high.

It is important to speak with a doctor or dietician before starting the keto diet, especially for people with diabetes, as careful monitoring of blood sugar and ketone levels is necessary. The keto diet may require a period of adjustment, and medication adjustments may be needed to avoid negative side effects.

The keto diet may be hard to maintain long-term

The keto diet can also be socially isolating, as it may be difficult to eat out or socialise while adhering to the strict guidelines. The diet may also be expensive, as it often requires purchasing specialty foods and supplements. Additionally, the keto diet can be time-consuming, as meal planning and preparation can be more complex.

The keto diet is not a balanced approach to nutrition, as it severely limits carbohydrates and emphasises high-fat foods. This imbalance can lead to nutrient deficiencies, especially if the diet is followed for a long time. Some people may also experience side effects such as "keto flu," which includes symptoms like extreme fatigue and brain fog. These side effects can be off-putting and make it difficult to stick to the diet long-term.

Furthermore, the keto diet may not be safe for everyone. It can be dangerous for people with certain health conditions, such as kidney disease, and it may increase the risk of other health issues, including heart disease and cancer. There is also a lack of long-term research on the safety and effectiveness of the keto diet, and healthcare professionals caution against recommending it as a long-term solution.

Overall, while the keto diet may lead to rapid weight loss and have some potential benefits, it can be challenging to maintain in the long term due to its restrictive nature, social implications, cost, and potential health risks. It is important for individuals to carefully consider their personal circumstances and consult with a healthcare professional before starting the keto diet or any other restrictive diet.

The keto diet may be linked to an increased risk of cardiovascular disease

The ketogenic or "keto" diet is a popular weight-loss diet that involves consuming low amounts of carbohydrates and high amounts of fats. The diet restricts consumption of carbohydrates, the body's primary source of energy, and forces the body to break down fat for energy instead.

Increased risk of cardiovascular disease

Recent research suggests that the keto diet may be associated with an increased risk of cardiovascular disease. A study presented at the American College of Cardiology's annual scientific session found that a keto-like diet may be associated with higher levels of "bad" cholesterol and twice the risk of cardiovascular events such as chest pain, blocked arteries requiring stenting, heart attacks and strokes.

The study defined a keto-like diet as consisting of no more than 25% of total daily calories from carbohydrates and more than 45% of total daily calories from fat. The study found that, among participants on this diet, those with the highest levels of LDL cholesterol were at the highest risk for a cardiovascular event.

Cholesterol levels

The keto diet's restriction of carbohydrates can lead to an increase in cholesterol levels, specifically LDL cholesterol, which is considered a significant risk factor for cardiovascular disease. However, there is conflicting evidence on the risk of cardiovascular disease in people with type 2 diabetes following a keto diet.

Inter-individual differences

It is important to note that not everyone responds to the keto diet in the same way. While cholesterol levels tend to rise on this diet, some people's cholesterol concentrations can stay the same or go down, depending on various underlying factors. Further research is needed to identify specific characteristics or genetic markers that can predict how individuals will respond to the keto diet.

Limitations and future research

The study's findings are limited by the fact that participants provided dietary information at only one point in time. As the study was observational, it can only show an association between the keto diet and an increased risk of cardiovascular events, not a causal relationship. However, the findings merit further research, especially given the popularity of the keto diet.
