Keto headache is one of the keto flu-related effects. If you’re not sure what keto flu is, check out our story, what headache on Keto diet Flu is, and How to treat it for more information?

At first, transitioning to keto diet headache, the body undergoes a significant change from carbs to fats throughout its food supply. Depending on your no carb headache intake and the degree of insulin resistance before making this turn, the effects may be more or less severe. When the body gets used to using fats for energy instead of low carb headache, you can develop specific flu-like symptoms, including keto diet headaches on keto.

We named these keto headaches.

The changes the body undergoes during the ketosis headache process usually induce some symptoms called keto flu, the three major ones being:

  1. Mental or brain fog — If you cannot think straight and concentrate, you can feel brain fog. Your head can feel very bumpy, and your memory may not be as sharp as expected.
  2. Fatigue—this kind of tiredness is not emotional but physical. Easy things as you do every day. Working, maybe draining.
  3. A headache—this kind of headache would be dull, more often than not, nagging one that can cause nausea, outright pain, and even blurred vision. If it’s severe enough, it could be a migraine.

Causes headache on keto diet


Your body transforms into a ketosis headache phase within two to seven days after you initiate the keto diet and significantly decrease your low carb headache intake (somewhere near 20 to 50 grams per day). That suggests that the body continues to make ketones and burn fat for energy to compensate for the lack of carbohydrates coming in. You also go through no carb headache withdrawal, which brings on symptoms such as keto headaches (yes, that’s a thing).

The keto headache arises during the transformation into ketosis headaches. “As a result of consuming fewer carbohydrates, particularly sugar, keto diet headaches can occur,” says Valerie Agyeman, RD, dietitian of women’s health and founder of Flourish Heights. Your body starts depending on ketones instead of glucose when you start the diet, which will cause your blood sugar levels to drop. Headache, in turn, will lead to low blood sugar. This transition to ketosis can affect the brain, leading to fog in mind and headaches on keto; she continues.

Usually, how long do keto headaches last?

Ketosis headache is very personal, like other symptoms of keto flu. “This depends on everyone, but in the early phase of adopting this stringent diet, most individuals get headaches and will improve as you keep hydrated and consume lots of healthy foods,” says Agyeman. The discomfort can even show up at any time of day.

“There is the best way to do it healthily, just as any eating schedule,” says Keri Glassman, RD, a nutritionist at Nutritious Life. Your body would have a difficult time surviving on this diet if you go right and eat processed foods when they are called ‘keto headaches’ and load up on only hard-to-digest foods and will lead to more keto diet headaches, brain fatigue, aches, and pains.’

Advice for treating or avoiding keto diet headache on the keto diet

It will help minimize the chance of dehydration by maintaining adequate hydration and consuming lots of healthy foods. This will relieve keto headaches and discourage them from taking place in the first place.

Several unique tips are available here:

  1. Salt the diet of yours. To lower the chance of an electrolyte deficiency, try gently salting your food.
  2. Try a substitute for electrolytes. Your chance of vomiting and keto flu symptoms can be reduced by taking an electrolyte replacement.
  3. Stop heavy exercises. During the early days of keto, refrain from vigorous activities, as they will stress the body and increase the risk of keto diet headaches.
  4. Eat more low-carb foods that are abundant in water. The high water content of cucumbers, zucchini, spinach, celery, cabbage, and raw tomatoes will help you stay hydrated. Some of them are healthy electrolyte sources, too.
  5. Eat more foods that are high in electrolytes. Keto-friendly foods are rich in potassium, including avocados, lettuce, mushrooms, and tomatoes. Similarly, magnesium is increased in almonds, spinach, pumpkin seeds, and oysters and is suitable for keto.
  6. Drink a lot of water. Since water loss affects the initial phases of keto, it is essential to drink sufficient fluids. Get at least 2 liters (68 ounces) of water per day.
  7. Limit your consumption of alcohol. Alcohol is a diuretic, meaning that it helps you urinate more often and can raise the risk of dehydration.

Consult a health provider to ensure that an underlying medical problem is not to blame if you appear to have headaches for several days or weeks on the keto diet.
