Gluten And Keto: Are They Compatible?

The ketogenic diet and the gluten-free diet are two popular diets that people use to meet their nutritional needs and manage their food allergies and sensitivities. While the keto diet is characterised by low-carb and high-fat food choices, the gluten-free diet is medically necessary for people with gluten intolerance or celiac disease. Although there are some similarities between the two diets, they are quite different. For instance, gluten-free food is not always low-carb, and keto-friendly food is not always gluten-free.

Gluten-free vs keto-friendly foods

The keto diet and gluten-free diets are two of the most common diets that people use to suit their nutritional and health needs. However, they are not the same thing.

The ketogenic diet is a very low-carbohydrate, high-fat diet. The body replaces carbohydrates with fat, which can put your body into a state of ketosis. In ketosis, the body uses fat instead of carbohydrates for energy.

A gluten-free diet involves avoiding gluten, a grain-based protein that adds structure and chewiness to food. Gluten is found in wheat, barley, rye, spelt, kamut, wheat berries, and triticale. It is also added to many packaged foods as a flavour enhancer, texturizer, and binder.

The keto diet is usually gluten-free because it involves eliminating most gluten-containing foods. However, some keto-friendly foods, like soy sauce, do contain gluten.

Gluten-free is not always keto-friendly. Gluten-free products often contain too many carbohydrates to be ketogenic. For example, sweet potatoes are gluten-free but will not keep you in a state of ketosis.

Who should go on a keto diet?

Those who want to lose weight, as well as people with diabetes, may benefit from a keto diet. This is because it helps with weight loss, insulin levels, and reducing excess fat. It may also have benefits for heart health.

Who should go on a gluten-free diet?

People with autoimmune diseases like celiac disease and Crohn's disease should go on a gluten-free diet. Those with irritable bowel syndrome (IBS) may also benefit from eliminating gluten.

The main difference is the reason for going on the diet. A gluten-free diet is usually adopted to prevent pain and discomfort caused by gluten intolerance, whereas most people choose a keto diet to lose weight.

Gluten-free foods that are not keto-friendly

Gluten is a protein found in wheat, rye, and barley. It is also commonly found in carbohydrate-rich foods such as bread, pasta, crackers, and cereals. While a keto diet is often gluten-free, as it typically involves avoiding wheat and other grains, there are some gluten-free foods that are not keto-friendly. This is because a keto diet is focused on drastically reducing carbohydrate intake and replacing carbohydrates with fat, which puts the body into a state of ketosis.

• Fruits and vegetables: While some berries are allowed on a keto diet, most fruits and starchy vegetables are not due to their high carbohydrate content.
• Sweet potatoes: Although gluten-free, sweet potatoes are not keto-friendly as they are high in carbohydrates and will not keep you in a state of ketosis.
• Beans and legumes: These are not typically allowed on a keto diet due to their high carbohydrate content.
• Processed gluten-free foods: Many gluten-free products are highly processed and contain refined carbohydrates, such as bread, pasta, and cookies. These are not keto-friendly as they are high in carbohydrates.
• Oats: While oats themselves do not contain gluten, most commercial oats are cross-contaminated with gluten during harvesting and processing. Therefore, oats are not considered keto-friendly.

In summary, while a keto diet often overlaps with a gluten-free diet, there are some gluten-free foods that are not keto-friendly due to their high carbohydrate content.

The benefits of a gluten-free diet

A gluten-free diet is essential for people with celiac disease, an autoimmune condition where the body attacks the small intestine when gluten is consumed. The condition can cause symptoms such as belly pain, nausea, bloating, and diarrhoea, and can lead to nutritional deficiencies, multiple sclerosis, and neurological conditions if left untreated. As such, a strict gluten-free diet is the only effective treatment for celiac disease.

However, a gluten-free diet may also be beneficial for people with non-celiac gluten sensitivity, a controversial diagnosis that is hard to differentiate from other gastrointestinal conditions. People with gluten sensitivity may experience a range of symptoms, mostly gastrointestinal, when they consume gluten. These symptoms can include constipation or diarrhoea, as well as numbness in the extremities.

Even if you don't have celiac disease or gluten sensitivity, you may still benefit from a gluten-free diet. Gluten-containing foods are not especially nutrient-dense, so replacing grains with vegetables, nuts, meat, fish, and fruits can be a nice way to bring more vitamins and minerals into your diet. Additionally, some people without diagnosed gluten issues report losing weight and experiencing other health improvements when cutting out gluten.

It's important to note that gluten-free does not necessarily mean healthier. Many products marketed as "gluten-free" are highly processed and may contain more sugar and less fibre than their gluten-containing counterparts. As such, it's important to pay attention to what replaces gluten-containing foods in your diet and ensure you're still getting adequate nutrition.

The benefits of a keto diet

The ketogenic diet is a very low-carb, high-fat diet. It works by depleting the body of its sugar reserves, causing it to break down fat for energy. Here are some of the benefits of the keto diet:

• Supports weight loss: The keto diet may help a person lose weight by boosting metabolism and reducing appetite.
• May reduce acne: Eating a diet high in processed and refined carbohydrates may alter the balance of gut bacteria and cause blood sugar to rise and fall significantly, both of which can adversely affect skin health.
• May reduce the risk of certain cancers: The keto diet may be a safe and suitable complementary treatment to use alongside chemotherapy and radiation therapy in people with certain cancers.
• May improve heart health: The keto diet may help to lower cholesterol, which may, therefore, reduce a person’s risk of heart complications.
• May protect brain function: The ketones that generate during the keto diet may strengthen and protect the brain and nerve cells.
• Improves PCOS symptoms: A high-carbohydrate diet can cause adverse effects in people with PCOS, such as skin problems and weight gain.
• May reduce seizures: The keto diet may reduce seizures in people with epilepsy.

The differences between gluten-free and keto diets

A gluten-free diet is one that explicitly excludes gluten from meals. Gluten is a protein compound found in grains such as wheat, barley, rye, and others. It is what gives dough its sticky texture and is often used in food production to enhance texture and flavour. Gluten-free diets are normally used to treat people with celiac disease or those who have gluten sensitivity and experience discomfort and symptoms after consuming gluten.

A keto diet is a very low-carb, high-fat diet. It involves a substantial reduction of carbohydrate intake, which is replaced with fat. The purpose of the keto diet is to put your body into a metabolic state known as "ketosis", where it will start burning fat for fuel instead of carbohydrates.

The main difference between a keto and gluten-free diet is the reasoning behind needing to go on one. A keto diet is usually a choice made to lose weight or improve overall health, whereas a gluten-free diet is often a medical necessity. Those on a gluten-free diet need to be careful of cross-contamination, ensuring that gluten is not hiding in other places such as in shampoos, soaps, cosmetics, vitamins, and medications.

Gluten-free diets are not always low-carb, and vice versa. Many products that are labelled "gluten-free" are highly processed and contain other thickeners and binders that are too high in carbs to be considered keto. These foods are often high in sugar and other carbohydrates that can kick someone out of ketosis.

Who are these Diets For?

A keto diet is suitable for those wanting to lose weight, improve metabolic health, or manage diabetes. A gluten-free diet is necessary for those with celiac disease, wheat allergy, or gluten sensitivity.

On a keto diet, you should eat fatty foods such as fatty fish, meat, eggs, low-carb vegetables, cheese, butter, cream, and healthy oils. Any food that is high in carbohydrates should be eliminated or limited, including grains and starches, fruits, sugary foods, root vegetables, alcohol, beans, and legumes.

On a gluten-free diet, you can eat fruits, vegetables, meats, fish, dairy, grains such as rice, buckwheat, quinoa, corn, and tapioca (as long as they are labelled gluten-free), and starches and flour such as potatoes, corn, chickpea flour, and soy flour. Baked goods, bread, pasta, snack foods, beverages, cereals, sauces, and couscous should be avoided, as they often contain gluten.

Benefits and Negative Effects

Both diets have been associated with a variety of health benefits. A keto diet can help with weight loss, improved energy, reduced cravings, and enhanced cognition. It is also a promising therapy for chronic conditions like type 2 diabetes, cancer, and Alzheimer's disease. A gluten-free diet can help to ease digestive symptoms, reduce inflammation, and improve energy levels.

However, there are also potential negative effects to consider. Both diets may put you at risk of nutrient deficiency due to the elimination of too many foods. In addition, the lack of fibre from sources like wheat bran and fruits may lead to bowel issues such as constipation.
