Headaches are a common side effect when starting a ketogenic diet.

 

The headaches on keto are often caused by a combination of factors, including dehydration, electrolyte imbalances, and carbohydrate withdrawal. When you start a ketogenic diet, your body goes through a period of adaptation as it switches from using carbohydrates as its primary fuel source to using fat. During this time, your body may experience a temporary shortage of carbohydrates, which can lead to headaches and other symptoms

Dehydration is another common cause of headaches on the ketogenic diet, as the diet can have a diuretic effect and cause increased urination, leading to fluid loss. It’s important to drink plenty of water and consume electrolytes, such as sodium, potassium, and magnesium, to maintain proper fluid balance.

To help alleviate headaches on the ketogenic diet, it is recommended to drink plenty of water, consume electrolytes, and gradually reduce carbohydrate intake instead of abruptly cutting them out. Additionally, some people find that increasing their fat intake and consuming more low-carb vegetables can also help. If headaches persist or become severe, it’s important to consult with a healthcare professional to rule out any underlying medical conditions.
