Starting a new diet can often lead to headaches, and there are several reasons why this may happen. A common cause is dehydration, which can be brought on by limiting fluid intake or exercising vigorously without rehydrating. Another cause could be low blood sugar, which can occur when there are long periods between meals, irregular eating patterns, or a reduction in calorie intake. Certain foods can also trigger migraines, such as aged cheeses, monosodium glutamate (MSG), dried meats and fruits, and highly processed foods. Additionally, vitamin and mineral deficiencies, stress, lack of sleep, and irregular eating patterns can all contribute to headaches when starting a new diet.

What You'll Learn
Dehydration and low blood sugar
Low blood sugar, or hypoglycemia, can also cause headaches, especially in people with diabetes or prediabetes. Skipping meals, fasting, or going for long periods without eating can lead to low blood sugar levels, resulting in headaches. Eating smaller, more frequent meals and snacks throughout the day can help maintain blood sugar levels and prevent hypoglycemia-induced headaches. Consuming complex carbohydrates, such as potatoes and other starchy vegetables, can also help manage blood sugar levels.
It is important to listen to your body and make necessary adjustments to your diet and fluid intake to prevent dehydration and low blood sugar, which can cause headaches and negatively impact your health.

Hunger and fasting
Fasting can induce a migraine in people who are prone to them. However, fasting headaches are more likely to feel like tension headaches. They are usually mild to moderate in intensity, non-pulsating, and located at the forehead. The longer you go without eating, the more likely you are to experience a fasting headache. A study conducted in Denmark found a lifetime prevalence rate of 4.1% for fasting headaches. Another small study from 2023 found that 61% of individuals experienced headaches while on an intermittent fast.
The exact cause of fasting headaches is still unknown. However, several factors have been proposed, including hypoglycemia or low blood sugar, dehydration, caffeine withdrawal, and stress. Fasting headaches typically occur after at least 16 hours of fasting and resolve within 72 hours of resuming food intake. They are coded to Group 10 of the second edition of the International Classification of Headache Disorders ("Headache attributed to disorder of homeostasis").
Low blood sugar has been implicated as a possible cause of fasting headaches. However, some scientists argue that blood sugar levels are not the primary cause, as glycogen levels in the liver are typically sufficient to maintain normal blood sugar levels for 24 hours. Additionally, low blood sugar-related to insulin use does not cause headaches in people with migraines.
Caffeine withdrawal has also been linked to fasting headaches. However, this theory is controversial, as caffeine-withdrawal headaches usually occur about 18 hours after the last caffeine intake, and people who do not regularly consume caffeine can still experience fasting headaches. Dehydration is another proposed cause of fasting headaches, as the lack of regular meals during intermittent fasting may lead to insufficient fluid intake.
While the exact causes of fasting headaches are still not fully understood, it is clear that fasting can trigger headaches in some individuals. The best way to prevent fasting headaches is to maintain regular meals and adequate fluid intake.

Lack of nutrients
A diet lacking in nutrients can cause headaches in several ways. Firstly, dehydration is a common trigger for headaches. This can be caused by not drinking enough fluids, limiting your fluid intake, or losing fluids through sweat without replenishing them. Dehydration can also occur if you consume too many caffeinated beverages, as they have a diuretic effect, causing you to lose more fluids.
Secondly, a lack of specific nutrients can contribute to headaches. For example, low levels of magnesium have been linked to headaches and migraines. This is because magnesium is an electrolyte that helps balance the fluids in your body, and a deficiency can make your response system less equipped to deal with stress, triggering headaches. Similarly, low levels of other electrolytes like sodium and potassium can also lead to headaches.
Additionally, vitamin deficiencies can play a role in headaches. A lack of vitamin B2 (riboflavin) is associated with migraines, and B vitamins are crucial for nerve health. Vitamin D deficiency has also been linked to headaches, although too much vitamin D can also be problematic. Furthermore, low iron levels can contribute to headaches since iron is needed to produce red blood cells that transport oxygen to the brain.
Lastly, a diet that causes a significant drop in blood sugar levels can trigger headaches. This often occurs when you consume fewer calories than your body needs, leading to low blood glucose levels, which can create muscle tension and contribute to headaches.
To address these nutrient-related causes of headaches, it is important to ensure adequate hydration by drinking enough water throughout the day. Eating a variety of whole foods can help ensure you get the necessary nutrients, including magnesium-rich foods like spinach, avocado, and almonds. It may also be beneficial to consider taking supplements, such as B2 or magnesium, but always consult a healthcare professional before starting any supplementation.

Stress
Dieting can be stressful, and stress is a common cause of headaches. A drop in blood sugar can trigger the release of stress hormones, which in turn can cause a headache. This can be a particular problem when dieting, as a restricted diet can lead to lower blood sugar levels.
In addition, stress can be a trigger for migraines, which are typically more severe and only affect one side of the head. People who experience migraines have an irritable nervous system, and stress can lower their migraine threshold, leading to more frequent attacks.
To reduce stress-related headaches when dieting, it is important to address the stressors in your life. This may include improving your sleep patterns, introducing relaxation techniques such as yoga, and ensuring you are eating a balanced and nutritious diet.
It is also worth noting that other factors related to dieting can contribute to stress and headaches. For example, dehydration, irregular eating patterns, and vitamin or nutrient deficiencies can all be triggers. Therefore, it is important to drink plenty of water, eat regular meals, and ensure your diet includes a variety of whole foods to get the nutrients your body needs.

Food allergies and intolerances
Dieting can cause headaches due to hunger, low blood sugar, dehydration, caffeine intake, irregular eating patterns, and nutritional deficiencies. While true food allergies rarely cause headaches, food intolerances and sensitivities can trigger migraines and headaches.
Food allergies, intolerances, and sensitivities can manifest as headaches. Food allergy headaches are characterised by facial pain, a throbbing sensation, and unilateral pain. Food intolerances are more likely to cause headaches than true allergies, and certain foods are common triggers. These include aged cheeses, dried meats and fruits, high-sugar and
Food sensitivities can also trigger migraines. IgG reactivity to various foods has been linked to migraines, and an elimination diet guided by IgG test results has helped reduce migraine frequency. The Everlywell Food Sensitivity Test is another at-home option to identify food sensitivities.
If you suspect food allergies, intolerances, or sensitivities are causing your headaches, you can try an elimination diet or food challenge. Keeping a food diary or journal can help identify trigger foods, and once identified, these triggers can be avoided.

To prevent hunger headaches, eat a balanced meal with foods full of vitamins and nutrients, drink plenty of water, eat frequent smaller meals, and get a good night's rest.
The most common foods that trigger migraines are aged cheeses, foods containing monosodium glutamate (MSG), dried meats and fruits, high-sugar and processed foods, and meat products containing additives such as nitrates and nitrites.
An elimination diet involves removing certain foods from your diet to see if your symptoms improve. This can help identify food intolerances, sensitivities, and potential allergies.
