Keto And Migraines: What's The Connection?

The ketogenic diet is a high-fat, moderate-protein, low-carbohydrate diet. When the body goes into a state of ketosis, it burns ketones for energy instead of glucose. Anecdotal evidence suggests that the keto diet can help with migraine attacks, and some studies have shown a reduction in migraine frequency and severity. However, there is also evidence that the keto diet may increase headache frequency, and it can be hard to adhere to.

Ketogenic diets can reduce inflammation, a key cause of migraines

The ketogenic diet is a high-fat, moderate-protein, and low-carbohydrate diet. When a person limits their intake of carbohydrate-rich foods (grains, legumes, fruits, starchy vegetables, etc.) or fasts, their body enters a state called ketosis. In ketosis, the body burns ketones for energy instead of glucose, which is derived from carbohydrates. Ketones, or ketone bodies, are organic compounds released from fat cells.

The ketogenic diet has been found to lower inflammation in the brain and throughout the body. This is due to the diet's effect on reducing the production of inflammatory markers, such as pro-inflammatory cytokines, and increasing anti-inflammatory markers.

Lowering Inflammatory Markers

• Insulin: Insulin reduction is a key mechanism by which the ketogenic diet reduces inflammation. Insulin resistance is associated with increased production of pro-inflammatory cytokines such as TNF-α, IL-1α, IL-1β, IL-6, and leptin.
• Glucose: Sugar is inflammatory, and excess sugar in the body can cause high amounts of insulin production and increased inflammation.
• Free Radicals: Excess sugar in the body can also lead to the production of free radicals, which inflame the linings of blood vessels and stimulate the body's immune system to respond.

Increasing Anti-Inflammatory Markers

• Beta-hydroxybutyrate: Beta-hydroxybutyrate, one of the three ketone bodies produced during ketosis, has been found to block immune system receptors linked to inflammation.
• Adenosine: The ketogenic diet increases adenosine levels, which can act as a pain reliever and fight inflammation.

The Ketogenic Diet and Migraines

Research suggests that the ketogenic diet may be effective in reducing migraine frequency, severity, and duration. This is partly due to the diet's ability to reduce inflammation, which is a key contributor to migraines.

A study by Di Lorenzo et al. (2019) compared the effects of a ketogenic diet and a low-calorie non-ketogenic diet on obese people with episodic migraine. The ketogenic diet group experienced a greater reduction in headache days (-3) compared to the low-calorie diet group. Additionally, 75% of patients in the ketogenic diet group had a 50% response rate, compared to only 8% in the low-calorie diet group.

Another study by Haslam et al. (2021) investigated the effects of a ketogenic diet therapy (KDT) compared to an "anti-headache" dietary pattern (AHD) in people with a history of migraines. Although there were no statistically significant differences in migraine frequency, severity, or duration between the two dietary interventions, a clinically important trend toward lower migraine duration was observed in the KDT group.

The ketogenic diet has been shown to reduce inflammation, a key cause of migraines. This anti-inflammatory effect is due to the diet's impact on lowering inflammatory markers and increasing anti-inflammatory markers in the body. Research suggests that the ketogenic diet may be effective in reducing migraine frequency, severity, and duration, partly due to its anti-inflammatory properties. However, more high-quality research is needed to confirm these findings.

The diet can help with weight loss, which is linked to migraine reduction

The keto diet is a high-fat, low-carbohydrate, and moderate-protein diet. By reducing carbohydrate intake, the body enters a metabolic state called ketosis, using ketone bodies as an alternative energy source to blood sugars.

The keto diet has been shown to have short-term benefits such as weight loss, lowered insulin resistance, and reduced high blood pressure, cholesterol, and triglycerides. Weight loss is linked to migraine reduction, and obesity is comorbid with migraine.

Some studies have shown that the keto diet can reduce migraine frequency, duration, and severity. A 2021 study by the Hunter Medical Research Institute and the University of Newcastle found a "clinically important trend toward lower migraine duration". However, the keto diet can be difficult to follow and may cause side effects such as fatigue and gastrointestinal issues.

The keto diet may not be suitable for everyone, and it is recommended to consult a doctor or dietitian before starting. It is important to maintain adequate hydration and electrolyte intake, especially sodium, potassium, and magnesium, to avoid potential side effects such as low energy, brain fog, and headaches.

The keto diet may also increase headache frequency, especially during the initial phase when the body is adjusting to the new diet. Additionally, the process of going into ketosis can be challenging due to triggers such as dehydration, electrolyte imbalances, and low blood sugar.

Overall, the keto diet has the potential to help with weight loss and reduce migraine attacks, but it may not work for everyone, and there are some potential side effects to consider.

The keto diet can cause side effects such as fatigue, constipation, and stomach upset

The keto diet is a high-fat, moderate-protein, low-carbohydrate diet. When a person limits their intake of carbohydrate-rich foods, such as grains, legumes, fruits, and starchy vegetables, the body goes into a state called ketosis. In ketosis, the body burns ketones for energy instead of glucose. Ketones are organic compounds released from fat cells.

The keto diet can lead to several side effects, including fatigue, constipation, and stomach upset. These side effects are often mild and transient, but they can impact an individual's overall well-being and quality of life.

Fatigue is one of the most commonly reported side effects of the keto diet. This may be due to the body's adjustment to using fat as an alternative energy source instead of glucose. The transition period may result in decreased energy levels and fatigue.

Constipation is another possible side effect of the keto diet. This may be related to the reduced intake of high-fibre carbohydrate sources, such as whole grains, legumes, and certain vegetables. Adequate fibre intake is essential for regular bowel movements, and a sudden change in diet can disrupt the balance.

Stomach upset or abdominal pain can also occur during the initial phase of the keto diet. This may be due to the sudden change in dietary habits and the body's adjustment to higher fat intake. Additionally, the keto diet can cause electrolyte imbalances, which can contribute to stomach discomfort.

It is important to note that these side effects are not universal and may vary from person to person. Some individuals may experience additional side effects, while others may not experience any at all.

To minimise these side effects, it is recommended to gradually transition to the keto diet, ensure adequate hydration, and include fibre-rich, low-carbohydrate vegetables in the diet. Consulting a healthcare professional before starting the keto diet can also help identify potential risks and develop a personalised plan to mitigate side effects.

The diet may not be safe for everyone, and it can be hard to stick to

The keto diet may not be safe for everyone. It can be hard to stick to, and it may not be suitable for those with certain dietary requirements or medical conditions.

The keto diet is a high-fat, low-carbohydrate, and moderate-protein diet. It involves getting about 70-80% of daily calories from fats, and a small percentage from protein and carbohydrates. The keto diet can be challenging to adhere to, as it requires a strict dietary plan and can be incompatible with a normal social life. It may also be unsafe for people with certain medical conditions, such as diabetes, as it can cause dangerously low blood sugar. Additionally, the keto diet can lead to side effects such as hunger, fatigue, constipation, headaches, and "brain fog."

The keto diet may be particularly challenging for those with migraine triggers related to diet, stress, hormone changes, poor sleep, bright lights, or caffeine. A 2021 study found that adults who experience migraines found it difficult to follow the keto diet accurately, and even those who did follow the diet closely experienced side effects like fatigue and gastrointestinal complaints. The keto diet may also be unsafe for people with diabetes, as it can cause dangerously low blood sugar.

Furthermore, the keto diet may not be suitable for everyone due to its restrictive nature. It eliminates many food groups, such as fruits, grains, sugar, and other caloric sweeteners, and requires careful planning to ensure adequate nutrient intake. The keto diet may also be challenging for those with food allergies or intolerances, as it restricts the consumption of certain food groups.

Overall, while the keto diet may offer potential benefits for migraine sufferers, it is important to consider the potential challenges and risks associated with this dietary approach. It may not be safe or feasible for everyone, and individuals should consult with a healthcare professional before starting the keto diet or making any significant dietary changes.

The keto diet can cause dehydration, which can trigger migraines

The keto diet is a high-fat, low-carbohydrate, and moderate-protein diet. By reducing carbohydrate intake, the body enters a metabolic state called ketosis, where it burns fat for fuel instead of blood sugars. While this diet has been linked to several health benefits, it can also lead to dehydration, which is a common trigger for migraines.

When you drastically cut down on carbohydrates and increase fat intake, your kidneys excrete more water, leading to increased urination. This can result in dehydration if fluid intake is not adequately increased to compensate for the loss. Dehydration can trigger migraines by affecting blood volume and flow, as well as electrolyte balance.

Studies on Keto and Migraine

Several studies have explored the link between the keto diet and migraine. A 2021 study by the Hunter Medical Research Institute and the University of Newcastle found that the keto diet did not reduce migraine frequency or severity but did shorten migraine duration by six hours. Another study, published in the *Journal of Clinical Medicine* in 2022, showed a reduction in monthly headache days and acute medication intake in migraine patients following a keto diet. However, the authors noted that the improvement could be due to factors other than weight loss.

Managing Migraines on Keto

If you are considering the keto diet and suffer from migraines, it is essential to stay properly hydrated by increasing your fluid intake. Additionally, consuming adequate amounts of sodium, potassium, and magnesium can help prevent dehydration-related headaches. It is also crucial to be mindful of other potential migraine triggers, such as stress, hormone changes, poor sleep, bright lights, and caffeine.
