Keto Vs Low-Carb: Which Diet Is Better For Diabetics?

The ketogenic diet has become an increasingly popular way to manage type 1 and type 2 diabetes. The diet is high in fat and low in carbohydrates, which can potentially change the way the body stores and uses energy, easing diabetes symptoms. However, the diet is restrictive and may not be sustainable for everyone.

There is evidence that a keto or very low-carb diet can be beneficial to people with type 1 and 2 diabetes, as well as prediabetes. The diet can help with weight loss, benefit blood sugar and insulin resistance, and promote overall health.

However, there are also potential risks associated with the keto diet. It is important to speak with a doctor before starting the keto diet, as it may not be suitable for everyone, depending on their health status. Additionally, there is limited information on the long-term effects of the diet, and it is not recommended for pregnant people.

Other low-carb diets, such as the Mediterranean diet, have also been found to be effective in managing diabetes. This diet is rich in whole grains, fish, and vegetables and is generally easier to follow than the keto diet.

When it comes to managing diabetes, it is important to work with a healthcare team to determine the best approach for the individual, as there is no one-size-fits-all solution.

The benefits of keto for diabetics

The keto diet is a very low-carb, high-fat, and moderate protein diet. It involves getting about 55% to 70% of your daily calories from fat, 25% to 35% from protein, and 5% to 10% from carbohydrates. This is a significant shift in eating habits for most people, as it requires drastically reducing carbohydrate intake and increasing fat intake.

The keto diet has several potential benefits for people with type 1 and type 2 diabetes:

• Improved blood sugar control: By reducing carbohydrate intake, the keto diet can help lower blood glucose levels, which is crucial for managing diabetes.
• Insulin resistance improvement: The keto diet may reduce the body's need for insulin, as it focuses on fat burning instead of carbohydrate breakdown. This can be especially beneficial for people with type 2 diabetes, who have insulin resistance.
• Weight loss: Keto is effective for short-term weight loss, which can improve insulin resistance and benefit people with diabetes.
• Increased "good" cholesterol: The keto diet is associated with increased levels of HDL cholesterol, which is heart-healthy and can reduce cardiovascular risk.
• Improved cognitive function: Some people report improved cognitive function while on the keto diet, although more research is needed to confirm this benefit.

Risks and Considerations

While the keto diet has potential benefits for diabetics, it's important to consider the risks and consult a doctor before starting:

• Nutrient deficiencies: The keto diet can be restrictive, and it's important to ensure adequate nutrient intake, especially fiber, vitamins, and minerals.
• Kidney stones: There is a risk of developing kidney stones while on the keto diet.
• Diabetic ketoacidosis (DKA): Restricting carbs too much can lead to high levels of ketones in the blood, a dangerous condition called DKA. This is more common in type 1 diabetes but can also occur in type 2 if ketones are too high.
• Not suitable for everyone: The keto diet may not be suitable for everyone, especially those with certain health conditions. It is crucial to consult a doctor before starting, especially for diabetics taking insulin or other medications.
• Long-term sustainability: The keto diet may be challenging to maintain over the long term due to its restrictive nature. Some people may find it more sustainable to transition to a less restrictive, balanced low-carb diet after initially following keto.

Food Choices on Keto

When following the keto diet, it's important to focus on heart-healthy fats and high-fiber, nutrient-dense carb sources:

• Healthy fats: Avocados, olive oil, nuts, and nut butters are good sources of healthy fats.
• Low-carb vegetables: Non-starchy vegetables like spinach, zucchini, mushrooms, and leafy greens are encouraged.
• High-fat dairy: Cream, sour cream, and cream cheese are allowed, but full-fat yogurt and cheese should be consumed in moderation.
• Meat and seafood: Poultry, meat, and seafood are good sources of protein on the keto diet.

In Conclusion

The keto diet has shown potential benefits for people with type 1 and type 2 diabetes, particularly in improving blood sugar control and reducing the need for insulin. However, it is important to consult a doctor and create an individualized plan, as the keto diet has risks and may not be suitable for everyone. Additionally, long-term sustainability should be considered, and transitioning to a less restrictive low-carb diet may be more beneficial in the long run.

The drawbacks of keto for diabetics

While the keto diet has been shown to be beneficial for people with type 1 and type 2 diabetes, there are some drawbacks and risks to consider. Here are some of the main concerns and potential negative consequences of following a ketogenic diet for diabetics:

Restrictive and Difficult to Maintain

The keto diet is highly restrictive, limiting carbohydrates to as low as 20 grams per day. This means cutting out or severely restricting many food groups, including legumes, fruits, starchy vegetables, grains, and dairy. Such drastic changes can be challenging to stick to over the long term, and many people find it unsustainable.

Potential Nutritional Deficiencies

By eliminating or reducing certain food groups, the keto diet may lead to nutritional deficiencies. It has been found to be lower in several essential nutrients, particularly fiber, as well as vitamins and minerals. This can have negative consequences for overall health and well-being.

Risk of Hypoglycemia

The keto diet can cause blood sugar levels to drop too low, a condition known as hypoglycemia. This is especially true if individuals taking medications that increase insulin levels do not adjust their dosages accordingly. Hypoglycemia can be dangerous and requires careful monitoring.

Increased Risk of Cardiovascular Disease

Some researchers suggest that the additional fat intake associated with the keto diet may increase the risk of cardiovascular disease (CVD) due to a buildup of fats in the arteries. People with diabetes already have an elevated risk of CVD, so this is a significant concern. However, the scientific evidence on this topic is conflicting, and more research is needed.

Kidney Stones and Nutrient Deficiencies

Long-term effects of the keto diet may include an increased risk of developing kidney stones and nutrient deficiencies, especially if the diet is followed for prolonged periods.

Lack of Long-Term Research

There is limited research on the long-term effects of the keto diet, particularly beyond 12 months. This makes it difficult to fully understand the potential benefits and risks of following this diet for an extended period.

Not Suitable for Everyone

The keto diet is not recommended for everyone. Pregnant or lactating individuals, those with a history of eating disorders, and people taking certain medications or with specific health conditions should not follow the keto diet without medical supervision.

Adverse Side Effects

The keto diet may lead to short-term side effects, including "keto flu," digestive issues, leg cramps, and fatigue. These side effects typically last a few days to a few weeks.

In conclusion, while the keto diet may offer some benefits for diabetics, it is important to carefully consider the potential drawbacks and risks. It is essential to consult with a healthcare professional before starting any new diet, especially one as restrictive as keto, to ensure it is safe and appropriate for your individual needs and health status.

The Mediterranean diet as an alternative

The Mediterranean diet is a popular alternative to the keto and low-carb diets, and it has been around for decades. It is more of a lifestyle than a diet, and it involves eating an abundance of fruits, vegetables, whole grains, beans, legumes, and healthy fats. It also includes moderate amounts of chicken, fish, eggs, and dairy, and limited amounts of red and processed meats, added sugars, and processed foods. It is generally a low-carb, moderately high-fat diet.

The Mediterranean diet has been found to be similarly effective as the keto and low-carb diets in controlling blood glucose levels and aiding weight loss. In a trial of 40 adults with Type 2 diabetes or prediabetes, participants who followed the Mediterranean diet were able to achieve similar drops in HbA1c levels (7%) and weight loss (7%) compared to those on the keto diet (9% and 8%, respectively). The Mediterranean diet also had the added benefit of lowering LDL cholesterol, while the keto diet increased it.

One of the main advantages of the Mediterranean diet is that it is less restrictive and easier to follow than the keto diet. It does not involve drastic reductions in carbohydrate intake, and it allows for more variety in dietary options. It also tends to be more sustainable in the long run, as it is not as strict and does not require as much planning and preparation.

In terms of health benefits, the Mediterranean diet is well-known for its ability to support heart health and reduce the risk of cardiovascular disease. It has also been linked to a lower risk of stroke, improved blood pressure levels, and protection against plaque buildup in the arteries. Additionally, the Mediterranean diet can help improve blood sugar management and may be associated with a lower risk of developing type 2 diabetes. It has also been found to support healthy brain function and memory, as well as a reduction in symptoms of depression in older adults.

However, one potential downside of the Mediterranean diet is that it may be more time-consuming and expensive to prepare meals, as it focuses on whole and minimally-processed foods. Additionally, the lack of structure in the diet may make it challenging for some people to follow. Nevertheless, the flexibility that this eating pattern offers may be preferred by some individuals.

The Atkins diet as an alternative

The Atkins diet is a well-known and popular alternative to the keto diet, and it is often considered in relation to keto due to its low-carb approach. The Atkins diet was created by a cardiologist, Robert Atkins, and was first introduced in 1972. It has since evolved and now offers a few different plans, but the original version, now called Atkins 20, is still the most popular.

How it Works

The Atkins diet is a low-carb, moderate-protein, and high-fat diet. It is split into four phases, with specific daily net carb allowances:

• Phase 1 (Induction): 20-25 grams of net carbs per day until you are 15 pounds from your goal weight.
• Phase 2: 25-50 grams of net carbs per day until you are 10 pounds from your goal weight.
• Phase 3: 50-80 grams of net carbs per day until you reach your goal weight and maintain it for one month.
• Phase 4: 80-100 grams of net carbs per day for ongoing weight maintenance.

As you progress through the phases, you gradually increase your carb intake, which will eventually take your body out of ketosis. This flexible carb limit means Atkins allows for a wider variety of foods, including more fruits, vegetables, and even some grains.

Benefits

The Atkins diet may be a good alternative for those who find keto too restrictive. It is less restrictive overall, and you do not need to monitor ketones or stick to certain macronutrient targets. It may also be easier to stick to in the long term as it becomes less restrictive over time, allowing for more carbs and a greater variety of foods.

Downsides

The Atkins diet may not be suitable for those with diabetes, heart disease, or kidney disease. There is also a risk of nutrient deficiencies, especially if you do not carefully plan your diet.

Comparison to Keto

Both Atkins and keto are low-carb diets that can aid weight loss, diabetes management, and heart health. The main difference is that Atkins gradually increases carb intake, while keto keeps it very low to maintain ketosis. Atkins is generally less restrictive and may be easier to stick to, but keto may be beneficial for those who need a more stringent approach.

Overall

The Atkins diet can be a good alternative to keto, especially for those who find the restrictions of keto too challenging. However, it is important to consult a healthcare professional before making any drastic dietary changes, especially if you have any chronic health conditions.

The paleo diet as an alternative

The paleo diet is based on the food that is believed to be similar to the daily diet of cavemen and cavewomen. It is a high-protein, low-carb food regimen that minimises processed foods and emphasises meats and vegetables.

The paleo diet is thought to be especially useful for people with type 2 diabetes. A study involving 14 people suggested that those living with type 2 diabetes who followed the paleo diet were able to lower their blood pressure, stabilise their blood sugar levels, and reduce their cholesterol significantly in only two weeks. However, other studies suggest that such short-term improvement is not unique to the paleo diet and that the long-term link between paleo and type 2 diabetes is inconclusive.

The paleo diet is typically lower in carbohydrates and moderate or higher in fat. It is categorised into two groups of food: in and out. Pre-agricultural/animal foods such as red meat and fish are "in", but Neolithic-era foods such as grains and dairy are not. Alcohol, dairy, and coffee are generally rejected on the diet, but some people may choose to modify their diet to allow these foods on occasion.

People with type 2 diabetes who follow a paleo diet may find that it helps them better control their blood sugar. The diet also encourages whole, unprocessed foods, which is a healthy approach. Plus, the "bulkiness" of the foods may mean you'll feel full on fewer calories, encouraging weight loss, which is also beneficial for people with type 2 diabetes who are overweight, to minimise the risk of complications.

However, some experts are sceptical about the paleo diet for good health and diabetes management. The diet almost completely eliminates certain food groups, like grains, and traditional wisdom would argue that it's less healthy than a more well-rounded diet. Many versions of the paleo diet also encourage the consumption of saturated fat, such as the fat found in red meat, which can cause elevated cholesterol levels. This can be an especially dangerous problem for people with diabetes, because they are more likely to develop heart disease than people without diabetes.

If you have type 2 diabetes and are interested in trying a paleo diet, you should consult your doctor or a registered dietitian before beginning the program.
