Keto And Diabetes: Is It A Good Fit?

The ketogenic diet is a low-carb, high-fat eating plan 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. While the keto diet can be an effective strategy for managing blood glucose and weight, it is not suitable for everyone. This paragraph will explore the benefits and drawbacks of the keto diet for people with diabetes and discuss whether it is the best dietary approach for managing the condition.

The benefits of keto for diabetics

The keto diet is a low-carb, high-fat eating plan that has been linked to several health benefits for people with diabetes. Here are some of the advantages of the keto diet for diabetics:

Improved Blood Glucose Control

The keto diet can help diabetics manage their blood glucose levels effectively. By restricting carbohydrate intake, the keto diet reduces spikes in blood sugar after meals. This is especially beneficial for people with type 2 diabetes, as it allows them to maintain blood sugar levels at a healthy, low level.

Weight Loss

The keto diet has been associated with significant weight loss, which can be beneficial for diabetics. Obesity is a major risk factor for insulin resistance, and losing above 10% of body weight can help put type 2 diabetes into remission. The keto diet's high-fat content and reduced carbohydrate intake can lead to a reduction in overall calorie intake, contributing to weight loss.

Reduced Insulin Requirements

The keto diet may reduce the body's insulin requirements. The restricted carbohydrate intake means the body needs less insulin to manage blood sugar levels. This can lead to a lower dependency on anti-diabetic medication, which is beneficial for those with type 2 diabetes.

Improved Glycemic Control

The keto diet has been shown to improve glycemic control in people with type 2 diabetes. A 2008 study found that participants who followed the keto diet saw greater improvements in glycemic control and were able to reduce their medication compared to those on a low-glycemic diet.

Lower Hemoglobin A1C Levels

The keto diet can help lower hemoglobin A1C levels, which is beneficial for diabetics. By reducing carbohydrate intake and keeping glucose levels low, the keto diet can help achieve the recommended A1C goal of 7% or less.

Improved Triglyceride Levels

Studies have shown that a long-term keto diet reduces triglyceride levels in people with obesity. High triglyceride levels are an independent risk factor for diabetes, so this improvement can be beneficial for diabetics.

While the keto diet offers these benefits, it is important to note that it also has potential drawbacks and risks. It is always advisable to consult a healthcare professional before making any drastic dietary changes, especially if you have a medical condition such as diabetes.

The drawbacks of keto for diabetics

While the keto diet can be beneficial for some people with diabetes, it also has several drawbacks and potential risks that should be carefully considered. Here are some key points to keep in mind regarding the drawbacks of the keto diet for diabetics:

• Nutrient Deficiencies: The keto diet restricts or excludes certain food groups, which can lead to nutrient deficiencies. It is important to consult with a doctor and a dietitian to find keto-friendly replacements for vital vitamins and nutrients.
• Difficult to Maintain: The keto diet is highly restrictive, making it challenging to follow in the long term. It requires careful planning and monitoring, and even with supervision, it is not recommended for longer than 12 months.
• Side Effects: Adopting the keto diet can result in various side effects, including "keto flu," which includes symptoms such as headaches, vomiting, constipation, mood swings, and reduced energy levels. These side effects are usually temporary but can last for a few weeks.
• Low Blood Sugar (Hypoglycemia): Restricting carbohydrates too much can lead to low blood sugar levels, especially if you are taking medications that increase insulin levels. This can be dangerous and requires careful monitoring to prevent hypoglycemic episodes.
• Cardiovascular Risks: 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 consideration.
• Lack of Long-Term Studies: There is a lack of robust long-term studies on the safety and effectiveness of the keto diet for people with diabetes. This makes it difficult to fully understand the potential risks and benefits of adopting this diet over a longer period.
• Social and Practical Challenges: Following the keto diet often involves significant cooking and meal preparation. Eating out or attending social gatherings can be challenging due to the restricted food choices. This can impact an individual's quality of life and make it difficult to maintain the diet in the long term.

How to follow a keto diet

The ketogenic diet is a high-fat, low-carb, low-to-moderate protein diet. It is a popular weight loss method and is also used to manage type 2 diabetes.

To follow the keto diet, you should restrict your carbohydrate intake to a maximum of 50 grams per day, with some sources suggesting a limit as low as 20 grams per day. This restriction on carbs will cause your body to enter a state of ketosis, where it will burn fat for fuel instead of carbohydrates.

• Eat keto-friendly foods: Focus on consuming full-fat dairy products, non-starchy and fibrous vegetables, meat, fish, eggs, and low-carb vegetables such as leafy greens and broccoli.
• Avoid certain foods: Stay away from starchy and high-carb foods like potatoes, sweet potatoes, corn, peas, beans, and fruits high in sugar. Also, limit your alcohol intake and opt for unsweetened coffee or tea instead.
• Prepare for the keto flu: In the first few days of the keto diet, you may experience flu-like symptoms such as fatigue, mental fogginess, stomach aches, and sleep issues. To remedy this, increase your intake of sodium, potassium, and magnesium, and consume more fat, especially MCTs.
• Calculate your calorie intake: Determine how many calories you need to consume each day based on your goals. If you want to lose weight, eat fewer calories than you burn, and if you want to gain weight, eat more.
• Adjust your macronutrient intake: In addition to calories, pay attention to the amount of fat, protein, and carbohydrates you consume. Typically, a keto diet consists of 70% fat, 20% protein, and 10% carbohydrates.
• Seek professional advice: Before starting the keto diet, consult with your doctor or a nutritionist, especially if you have other dietary restrictions or health conditions. They can help you determine if the keto diet is right for you and provide guidance on how to follow it safely and effectively.

Other diets for people with type 2 diabetes

While a keto diet may be beneficial for people with type 2 diabetes, it is not the only diet that can help manage the condition. Other diets that can help people with type 2 diabetes include:

The Mediterranean Diet

The Mediterranean diet is rich in whole grains, fish, legumes, fruits, vegetables, olive oil, and nuts. It is a low-carb, moderately high-fat diet. A study by Stanford Medicine found that this diet was as effective as the keto diet in controlling blood glucose in people with type 2 diabetes. The Mediterranean diet was also found to be easier to follow and provided more nutrients than the keto diet.

The Atkins Diet

The Atkins diet is a low-carb, high-protein diet. While it can aid in weight loss and help control diabetes symptoms, there is insufficient evidence to suggest that it is directly linked to diabetes control. A potential drawback of this diet is the possibility of low blood sugar, especially if paired with medications that increase insulin levels.

Plant-Based Diet

A plant-based diet has been found to significantly improve blood sugar, A1C, cardiovascular disease risk factors, gut bacteria responsible for insulin sensitivity, and inflammatory markers.

DASH Diet

The DASH diet focuses on fruits and vegetables, whole grains, fish and poultry, beans, nuts, and fat-free or low-fat dairy. It also involves capping sodium intake to 2,300 mg per day. This diet has been found to reduce blood pressure levels, a key risk factor for heart disease and kidney disease, which are elevated in people with diabetes.

Vegetarian or Vegan Diet

A meta-analysis found that a vegetarian diet helped people with diabetes achieve weight loss and improved glycemic control, as well as improved cardiovascular risks. A vegan diet, being a more restrictive form of the vegetarian diet, would likely provide similar or even more pronounced benefits.

Low-Fat Diet

While low-fat diets are not as popular as they once were, fat restriction is still synonymous with dieting for many. The ADA has concluded that lowering fat intake does not consistently improve blood sugar levels, except when it results in weight loss. Structured very-low-fat diets, such as the Ornish diet, may be more beneficial.

Intermittent Fasting

Intermittent fasting involves restricting eating to a certain number of hours per day or consuming a very low number of calories on certain days. Some research has shown benefits to fasting glucose and weight, but skipping meals may hinder blood sugar control or cause low blood sugar, especially for those on insulin or a sulfonylurea.

Paleo Diet

The paleo diet involves eating like our hunter-gatherer ancestors, focusing on fruits, vegetables, nuts, lean meat, and certain fats while eliminating grains, legumes, and most dairy. A 2020 review found that this diet improved glucose metabolism, including lower A1C and insulin resistance, but it did not outperform other diabetes diets.

Low-Calorie Diet

Evidence suggests that a short-term, low-calorie diet (800 to 1,200 calories per day) can lead to significant weight loss and reduced blood sugar levels in people with type 2 diabetes. Some individuals have even experienced remission of their type 2 diabetes. However, this type of diet is not safe or suitable for everyone, so medical advice should be sought before starting.

The history of keto

The ketogenic diet, or keto, is a high-fat, low-carbohydrate, and moderate-protein diet that has been used as a treatment for epilepsy since the 1920s. The idea of using fasting to treat epilepsy, however, is much older, dating back to at least 500 BC. In ancient Greece, physicians advocated for dietary restrictions to treat epilepsy, and Hippocrates recorded fasting as the only treatment for the condition.

The first modern study of fasting as a treatment for epilepsy was conducted in France in 1911 by physicians Gulep and Marie. They treated 20 children and adults with epilepsy and found that seizures were less severe during treatment. Around the same time, American osteopathic physician Hugh Conklin began recommending fasting to his epileptic patients, with a success rate of 50% for adults and 90% for children.

In the 1920s, Dr. Russell Wilder at the Mayo Clinic developed the ketogenic diet as a way to mimic the metabolism that fasting produces. Wilder hoped to obtain the benefits of fasting in a dietary therapy that could be maintained indefinitely. The ketogenic diet was widely used in the 1920s and 1930s as a treatment for epilepsy, but its popularity waned with the introduction of effective anticonvulsant medications.

In the 1970s, the ketogenic diet was reintroduced as a weight-loss method, with the publication of Dr. Atkins' book "Dr. Atkins' Diet Revolution". The book expounded on his years of medical research on low-carb dieting for weight loss and heart health. This was followed by other books promoting high-fat and low-carb diets, such as Dr. Phinney's "The Last Chance Diet" and "The Optifast Diet".

In the 1990s, the ketogenic diet gained further attention through media coverage, such as an episode of the TV show "Dateline" and the film "First Do No Harm", which starred Meryl Streep. The diet was also promoted by celebrities such as Oprah Winfrey, who endorsed "The Optifast Diet".

Today, the ketogenic diet is not only used as a treatment for epilepsy but is also popular for weight loss and is being studied for its potential therapeutic use in various neurological disorders, such as Alzheimer's disease, Parkinson's disease, and autism.
