The keto diet is a popular, low-carbohydrate diet that puts the body into a state of ketosis, causing it to burn fat for energy instead of glucose. While this diet can be effective for weight loss, it often causes dizziness, especially when first starting out. This is sometimes referred to as the “keto flu. To combat dizziness while on the keto diet, it is important to stay hydrated and slowly ease into the diet. Eating foods rich in potassium, like bananas, avocados, and leafy greens, can help maintain electrolyte balance, while citrus fruits and berries provide antioxidants that support circulation. Additionally, consuming healthy fats, like salmon and egg yolks, can provide vitamin D, which can help reduce dizziness.

What You'll Learn

Stay hydrated
Staying hydrated is crucial when experiencing dizziness on a keto diet. This is because the keto diet's drastic reduction in carbohydrate intake leads to a loss of fluids and electrolytes, causing dehydration and dizziness.
To stay hydrated, it is recommended to increase your water intake. The general guideline is to drink eight 8-ounce glasses of water per day, but this may vary depending on factors such as sex, activity level, and environment. It is also important to listen to your body and adjust your water consumption accordingly. For instance, if you are very active, you may need to drink more water to compensate for fluid loss through sweating. Additionally, drinking a glass of water with half a teaspoon of salt stirred into it can help alleviate keto flu symptoms, including dizziness.
It is worth noting that caffeine, sugar, and alcohol can be dehydrating, so it is advisable to limit or avoid these substances. Instead, focus on consuming hydrating fluids like water and herbal tea.
Along with hydration, it is essential to replenish electrolytes like sodium, potassium, and magnesium, which are often lost during the initial phase of the keto diet. You can add a pinch of salt to your water or consume bone broth or salted butter. Eating dark, leafy greens like spinach and kale can also help restore electrolyte balance.

Consume electrolytes
The keto diet is a very low-carb, high-fat diet that puts your body in a state of ketosis, where it burns fat for energy instead of glucose. This drastic reduction in carbohydrates can cause a drop in insulin levels, leading to a loss of fluids and electrolytes, which can result in dizziness.
To combat this, it is important to consume adequate electrolytes, such as sodium, potassium, and magnesium. You can increase your electrolyte intake by adding salt to your food or drinking salt water. Additionally, try incorporating more potassium-rich foods into your diet, such as avocados, bananas, leafy greens like spinach and kale, and citrus fruits. These foods not only help maintain electrolyte balance but also support nerve function and reduce dizziness.
You can also improve electrolyte absorption by taking an Epsom salt bath, which will also help soothe sore muscles. Bone broth, chicken stock, and beef stock are tasty options that can provide you with electrolytes and fluids.
It is worth noting that an extremely low-carb keto diet may result in the loss of some of the richest natural resources of electrolytes, such as starchy fruits and vegetables. Therefore, it is crucial to be mindful of your electrolyte intake and make necessary adjustments to prevent dizziness and other symptoms associated with electrolyte imbalances.

Eat foods rich in potassium
Dizziness is a common side effect of the keto diet. This is because the keto diet restricts carbohydrate intake, causing the body to burn fat instead of carbs for energy. This shift can lead to dehydration, electrolyte imbalance, and low blood sugar, all of which can cause dizziness.
To combat dizziness on keto, it is important to focus on hydration and stabilising blood sugar levels. Eating foods rich in potassium can help maintain the body's electrolyte balance. Potassium is a vital mineral that supports nerve signal transmission and muscle contraction. When entering ketosis, the body's electrolyte balance shifts, making it challenging to maintain adequate potassium levels.
- Avocados: Avocados are a staple on the keto diet as they are rich in healthy fats and potassium. A medium-sized avocado contains approximately 689-975 milligrams of potassium, which is about twice as much as a banana. Avocados are also high in fibre, which can help manage blood sugar levels and reduce the urge to snack on carb-heavy options.
- Leafy greens: Spinach and broccoli are excellent sources of potassium and offer anti-inflammatory benefits due to their high levels of antioxidants. However, spinach contains high levels of oxalates, which can contribute to kidney stone formation in susceptible individuals, so it should be consumed in moderation.
- Nuts and seeds: Almonds and sunflower seeds make great low-carb snacks and are excellent sources of potassium. Almonds contain 834mg of potassium per 100g, while sunflower seeds provide 710mg of potassium per 100g.
- Mushrooms: Mushrooms are a fantastic addition to a ketogenic diet due to their low carbohydrate content and high levels of essential nutrients, including potassium. White mushrooms, for example, provide about 318 milligrams of potassium per 100 grams.
In addition to eating potassium-rich foods, staying hydrated is crucial when on the keto diet. Drinking plenty of water and consuming electrolytes can help prevent dehydration and maintain fluid balance, reducing the risk of dizziness.

Avoid caffeine, sugar, and alcohol
Feeling dizzy when starting a keto diet is a common side effect. This is due to the body adapting to a low-carbohydrate intake and burning fat for energy instead of glucose. This causes a drop in insulin levels, leading to a loss of electrolytes and dehydration, which can result in dizziness.
To avoid or minimize dizziness on keto, staying adequately hydrated is crucial. It is recommended to drink water regularly and avoid dehydrating beverages such as those containing caffeine, sugar, or alcohol. Caffeine, for instance, restricts blood flow, affecting the flow of oxygen and nutrients throughout the body. Alcohol, being a depressant, slows functions like speech and movement, worsening dizziness and disrupting your sense of balance. Meanwhile, high-sugar foods can lead to blood sugar fluctuations, which can be dangerous, especially for people with diabetes.
If you tend to experience low blood sugar, proceed with caution when starting a keto diet. It is recommended to slowly ease into the diet rather than suddenly decreasing carb intake. Additionally, consuming complex carbohydrates, such as whole grains, can help prevent dizziness caused by low blood sugar.
It is important to note that everyone's body deals with the keto diet differently. Consult with your doctor or seek nutrition counseling before starting any new diet, especially if you have pre-existing health conditions.

Slowly transition to keto
Starting a keto diet involves limiting your body's primary source of fuel – carbohydrates – and replacing them with fats. This process is known as ketosis, and it can cause some unpleasant side effects, including dizziness.
The keto diet is a restrictive one, and it is recommended that you transition into it slowly. This is because the diet involves such strict limits on carbohydrates, so eating a nutritionally balanced diet takes careful planning and effort. It can take a few days for your body to enter ketosis, so a sudden influx of carbs and sugar when you stop the diet could be harmful.
To transition slowly to keto, you should first educate yourself about the diet. It is important to understand the drawbacks and health risks of keto, as well as the benefits. You should also consult a doctor or nutritionist, especially if you have any underlying health conditions.
When starting keto, it is recommended that you take several weeks to slowly reduce your carbohydrate intake. You should also increase your consumption of healthy fats and lean proteins. It is important to pay attention to the different categories of carbs – simple and complex. Complex carbohydrates are higher in fibre and nutrients, and they take longer to digest. These can be found in whole, unprocessed foods, including vegetables, whole grains, legumes, nuts, seeds, leafy greens and fruits.
It is also important to stay hydrated when starting keto, as the initial phase of the diet involves rapid water loss. Drinking plenty of water can help to prevent dizziness and other symptoms of the 'keto flu'.
