Keto Diet: Improving Diabetes Numbers, How Long?

The ketogenic diet is a high-fat, low-carb 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, through which the body produces ketones that burn fat for energy instead of carbohydrates. While the keto diet may be effective for some people with type 2 diabetes, it is not recommended for everyone. Scientific research has confirmed the keto diet's effectiveness in managing type 2 diabetes by lowering blood sugar and promoting weight loss. However, the keto diet can be notoriously difficult to stick to, and more research is needed to understand its long-term effectiveness and risks. This article will explore how long it takes for diabetes numbers to improve when following a keto diet.

The keto diet can reduce blood sugar

The ketogenic (keto) diet is a high-fat, low-carb diet that can be beneficial for people with type 1 and type 2 diabetes. The keto diet can help manage blood sugar levels and reduce the need for insulin. By cutting out carbohydrates, the body is forced to break down fats for energy, which can lead to lower blood sugar levels.

The keto diet focuses on consuming high-fat, moderate-protein, and very low-carb foods. Typically, this involves getting about 55% to 70% of daily calories from fat, 25% to 35% from protein, and only 5% to 10% from carbohydrates. This means limiting or avoiding carbohydrate-rich foods such as grains, fruits, bread, rice, and pasta. Instead, people on the keto diet eat more proteins and fats, such as meats and nuts, avocados, olive oil, and low-carb vegetables.

When you eat carbohydrates, your body breaks them down into sugars that enter your bloodstream. The more sugar in your bloodstream, the more insulin your body needs to process it. For people with diabetes, the body doesn't produce enough insulin or can't use it properly, leading to high blood sugar levels. By severely restricting carbohydrates, the keto diet can help lower blood sugar levels and improve glycemic control.

It may take a couple of weeks to a few months to see significant improvements in blood sugar levels on the keto diet. It's important to monitor your blood sugar levels regularly and work with your doctor to adjust your medication as needed. The keto diet can be challenging to stick to in the long term, and it may not be suitable for everyone. It's essential to consult with a healthcare professional before starting any new diet, especially if you have a medical condition like diabetes.

It can be hard to stick to long-term

The keto diet can be hard to stick to long-term due to its restrictive nature. It requires a major shift in eating habits, limiting carbohydrates to approximately 5% of overall daily calories, and can be challenging to maintain. People typically find it more beneficial to follow a moderate diet that is more sustainable long-term.

The keto diet is highly restrictive, with a focus on high-fat, moderate-protein, and very low-carbohydrate intake. This can be challenging for those who are used to consuming more carbohydrates in their diet. The standard keto diet recommends that about 55% to 70% of daily calories come from fat, while about 25% to 35% come from protein, and only 5% to 10% from carbohydrates. This often involves a significant reduction in carbohydrate-rich foods such as bread, rice, pasta, milk, and fruit.

The restrictive nature of the keto diet can lead to a higher risk of "yo-yo dieting," where individuals may strictly adhere to the diet for a period, only to revert to previous eating habits and experience weight gain. This can be dangerous for individuals with diabetes, as it can negatively impact blood sugar control and overall health.

Additionally, the keto diet may not be suitable for everyone, depending on their health status and individual needs. It is always recommended to consult with a healthcare professional before starting any new diet, especially for those with diabetes or other health conditions.

Furthermore, the keto diet may not be recommended for long-term use. Experts suggest that the benefits of the keto diet for type 2 diabetes need to be present over a 12-month or greater period to be considered effective. There is also a lack of evidence regarding the long-term safety and effectiveness of the keto diet, with healthcare professionals calling for more studies before recommending it for diabetes management.

It is important to note that there is no one-size-fits-all approach to diet and diabetes management. While the keto diet may work for some individuals, others may find more success with a different dietary approach, such as a plant-based or moderate low-carb diet. The key is to find an eating plan that meets personal preferences, needs, and health goals, and to work closely with a healthcare team to monitor any necessary medication adjustments.

It may not be suitable for everyone

While the keto diet has been found to be beneficial for people with type 1 and 2 diabetes, it may not be suitable for everyone.

The keto diet is a high-fat, moderate-protein, and very low-carb diet. It can be challenging to follow in the long term because it is highly restrictive. The standard keto diet focuses on getting you into "ketosis," a metabolic state in which your body burns fat instead of carbs for energy. The body achieves this state by breaking down fats to produce ketones, which circulate freely in the bloodstream.

However, there are certain groups of people who should not follow the keto diet due to potential health risks or negative outcomes. Here are some of the groups who may need to refrain from the keto diet:

• Pregnant and Lactating Women: The keto diet is not recommended for pregnant women as it can affect the baby's weight and development. It may also prevent the mother from getting the necessary nutrients during pregnancy. For lactating women, a low-carb intake can lead to a dangerous condition called ketoacidosis due to the metabolic changes and increased nutritional demands of milk production.
• People with Eating Disorders: The restrictive nature of the keto diet can trigger unhealthy eating patterns in people with active eating disorders or a history of disordered eating. It can have negative effects on their health in both the short and long term.
• People with Hypothyroidism: Insulin is needed to convert the inactive thyroid hormone T4 into the active hormone T3. The keto diet restricts carbohydrates to the point where there may not be enough insulin available for this process, potentially worsening hypothyroid symptoms.
• People with No Gallbladder: The keto diet requires a high intake of fat. Without a gallbladder or with gallbladder disease, there may not be enough bile to break down these fats, leading to malnutrition or unpleasant symptoms.
• People with Digestive Disorders: The keto diet tends to be low in fiber, which can be problematic for people dealing with irritable bowel syndrome (IBS) or chronic constipation. Adequate fiber is also important for maintaining a healthy gut microbiome.
• People at High Risk for Osteoporosis: Animal studies have shown bone mineral loss in mice and rats fed ketogenic diets. Children following keto diets for epilepsy have also been found to have poorer bone health. While the reason is not fully understood, experts advise caution for those at risk of osteoporosis.
• People with a History of Yo-Yo Dieting: The keto diet is extremely restrictive and challenging to stick to. It may not be the best approach for long-term success, and a more moderate or balanced diet may be preferable.
• People with Diabetes (Taking Insulin): For those taking insulin to manage their diabetes, extremely low-carb intake can lead to dangerously low blood sugar levels. However, some studies suggest that very low-carb diets may be beneficial for those with type 2 diabetes under medical supervision.

It is important to consult with a healthcare professional before starting the keto diet, as it may not be suitable for everyone depending on their health status and individual needs.

It can lead to weight loss

How the Keto Diet Leads to Weight Loss

The keto diet is a low-carb, high-fat eating plan that has been used for centuries to treat specific medical conditions. In the 19th century, it was used to control diabetes, and in 1920 it was introduced as a treatment for epilepsy. Today, it is also being explored as a potential weight-loss strategy.

The keto diet is distinctive for its exceptionally high-fat content, with typically 70% to 80% of calories coming from fat, while protein intake is moderate in comparison with other low-carb, high-protein diets. The standard keto diet asks that about 55% to 70% of your daily calories come from fat, 25% to 35% from protein, and 5% to 10% from carbohydrates.

The premise of the keto diet for weight loss is that if you deprive the body of glucose, its main source of energy, an alternative fuel called ketones is produced from stored fat. The brain demands the most glucose, about 120 grams daily, and cannot store it. During fasting or when very few carbohydrates are eaten, the body first pulls stored glucose from the liver and breaks down muscle to release glucose. If this continues for 3-4 days and stored glucose is fully depleted, blood levels of insulin decrease, and the body begins to use fat as its primary fuel.

When ketone bodies, which are the fuel source produced during ketosis, accumulate in the blood, this is called ketosis. Proponents of the keto diet state that if the diet is carefully followed, blood levels of ketones should not reach a harmful level as the brain will use ketones for fuel, and healthy individuals will typically produce enough insulin to prevent excessive ketones from forming.

There are several theories as to why the keto diet promotes weight loss:

• A satiating effect with decreased food cravings due to the high-fat content of the diet.
• A decrease in appetite-stimulating hormones, such as insulin and ghrelin, when eating restricted amounts of carbohydrates.
• A direct hunger-reducing role of ketone bodies—the body’s main fuel source on the diet.
• Increased calorie expenditure due to the metabolic effects of converting fat and protein to glucose.
• Promotion of fat loss versus lean body mass, partly due to decreased insulin levels.

Research has shown that the keto diet can be effective for weight loss. A meta-analysis of 13 randomized controlled trials found that the keto diet produced a small but significantly greater reduction in weight, triglycerides, and blood pressure, and a greater increase in HDL and LDL cholesterol compared with a low-fat diet at one year. Another study of 89 obese adults who followed a two-phase diet regimen (6 months of a very-low-carbohydrate keto diet and 6 months of a normal-calorie Mediterranean diet) showed a significant mean 10% weight loss with no weight regain at one year.

In addition to weight loss, the keto diet has been shown to improve health parameters associated with carrying excess weight, such as insulin resistance, high blood pressure, and elevated cholesterol and triglycerides. It can also be beneficial for people with type 2 diabetes, as it can help to improve insulin sensitivity and blood sugar management.

However, it is important to note that the keto diet may not be suitable for everyone, and there are some potential drawbacks and side effects. It can be challenging to maintain a very high-fat diet, and possible symptoms of extreme carbohydrate restriction may include hunger, fatigue, low mood, irritability, constipation, headaches, and brain fog. There may also be an increased risk of kidney stones, osteoporosis, and increased blood levels of uric acid (a risk factor for gout).

Additionally, the keto diet is highly restrictive, and it can be difficult to follow in the long term. It may also not be suitable for pregnant women, people with certain health conditions, or those who are vegetarians or vegans due to the key role that meats, eggs, fish, and dairy play.

Before starting the keto diet or any other weight-loss plan, it is important to speak to a doctor or dietitian to ensure that it is safe and suitable for you.

It can reduce the need for insulin

The ketogenic diet is a popular choice for people with diabetes as it can lead to significant improvements in blood sugar control and insulin sensitivity. This is because the keto diet is a low-carb, high-fat diet that can reduce the body's reliance on glucose as a primary fuel source, thereby lowering blood sugar spikes and improving insulin sensitivity.

When an individual reduces their carbohydrate intake, as is the case with the keto diet, their blood sugar levels tend to stabilize and insulin sensitivity improves. This is because carbohydrates are the macronutrient that has the most direct impact on blood sugar levels. By reducing carb intake, the body relies more on fat for fuel, which doesn't require insulin to be utilized by cells. This can lead to a reduction in the need for insulin injections or medication for people with diabetes.

The keto diet has been shown in numerous studies to be effective in improving glycemic control and reducing the need for insulin in people with type 2 diabetes. For example, a 2019 study published in *Diabetes Therapy* found that participants with type 2 diabetes who followed a ketogenic diet for 12 weeks experienced a significant reduction in their HbA1c levels, a marker for long-term blood sugar control. Additionally, they were able to reduce their insulin dosage or even discontinue insulin therapy altogether.

The mechanism behind this improvement is that the keto diet lowers blood sugar levels and improves insulin sensitivity, which means the body can utilize insulin more effectively. As a result, people with diabetes may require less insulin to manage their blood sugar levels effectively. It is important to note that the reduction in insulin dosage should be done under medical supervision to ensure that blood sugar levels remain stable and controlled.

Starting the keto diet often leads to a rapid decrease in blood sugar levels, and this can sometimes happen within a few days to a few weeks. However, the timeline for improvements in diabetes numbers can vary depending on individual factors such as age, activity level, and overall health. It is always recommended to consult a healthcare professional before starting any new diet, especially if you have a medical condition like diabetes. They can guide you on how to adjust your medication dosage safely as your diabetes numbers improve.
