The ketogenic diet, also known as the keto diet, is a low-carb, high-fat diet that has become increasingly popular. It involves drastically reducing carbohydrate intake and replacing it with fat, which puts the body into a metabolic state called ketosis. While the keto diet is an effective way to lose weight, it can also lead to dehydration due to the reduced intake of carbohydrates and sodium. As a result, it is crucial for those on the keto diet to focus on staying hydrated and increasing their water intake.

Dehydration is a common side effect of the keto diet
The keto diet also encourages dieters to eat whole foods that naturally have a lower sodium content compared to processed and packaged foods. This sodium and salt are vital for retaining water. Without these carbs, drinking water will not have the same effect. As this water has no carbs to absorb, it is expelled relatively quickly through sweating or urination, especially if you live somewhere with frequent hot weather. This can lead to severe dehydration for active individuals on keto or people frequently exposed to warm conditions.
The risk of dehydration is greater when first starting a ketogenic diet because your body is undergoing a lot of changes in how it handles water and electrolytes. It is recommended to drink at least 2-3 liters of water per day while on the keto diet, with men needing to drink about 5 glasses of water more than women a day. A general rule of thumb is to drink at least half of your body weight in ounces of water. For example, if you weigh 150 pounds, you should drink at least 75 ounces of water per day.
To avoid dehydration, it is also recommended to increase your sodium intake more than if you were following a diet that consisted of carbs. To help regulate your body temperature and energy levels, experts suggest adding more salt to your low-carbohydrate diet. 2.5 teaspoons of salt a day, or 5 grams of sodium, will help your body retain water to prevent dehydration.

The keto diet causes a loss of electrolytes
The ketogenic diet is a low-carb, high-fat diet that causes weight loss and provides numerous health benefits. When you restrict carbohydrates, your body enters a metabolic state called ketosis, where it becomes very efficient at burning fat for energy. While the keto diet has been supported by professionals and is considered a sure-shot way to lose weight, it can also lead to dehydration and electrolyte imbalances.
The keto diet can result in a diuretic-like response, causing frequent urination and initial weight loss, often attributed to water weight loss. This loss of water can further lead to a decrease in electrolyte levels, as electrolytes are minerals that help maintain hydration. Electrolytes like sodium, potassium, and magnesium are essential for several bodily functions, including maintaining hydration, acidity levels, and muscle and nerve function.
When on a keto diet, the body processes electrolytes differently due to reduced insulin levels. Insulin plays a role in maintaining the balance of sodium and other electrolytes, so when insulin levels drop, the kidneys excrete more sodium, disrupting the balance of electrolytes in the body. This electrolyte imbalance can lead to symptoms like muscle cramps, confusion, loss of alertness, and poor judgment, commonly referred to as the "'keto flu.'"
To manage electrolyte imbalances and dehydration, it is recommended to increase salt and water intake. Adding 2.5 teaspoons of salt or 5 grams of sodium to the diet can help the body retain water. Additionally, staying properly hydrated is crucial, and health experts recommend drinking around 64 ounces of water daily for those on the keto diet. However, the amount of water needed can vary depending on factors such as exercise, the extent of carb restriction, and the average temperature of one's location.
Overall, while the keto diet offers weight loss and health benefits, it is important to be mindful of potential electrolyte imbalances and dehydration. Proper guidance, adequate water intake, and electrolyte supplementation can help maintain optimal bodily function and performance while on the keto diet.

Drinking water helps the body burn fat
The ketogenic diet is a low-carb, high-fat diet that causes weight loss and provides numerous health benefits. The keto diet focuses on a low-carb, high-fat diet with an end goal of rapid weight loss once your body is in a state of ketosis. Staying hydrated during any diet is crucial, but with the keto diet, drinking water becomes all the more important to keep your water intake in check.
Drinking water is essential for burning off fat from food and drink, as well as stored fat. The process of metabolizing fat is called lipolysis. The first step of this process is hydrolysis, which occurs when water molecules interact with triglycerides (fats) to create glycerol and fatty acids. Upping your water intake may increase lipolysis, the process by which the body burns fat for energy. According to a 2016 mini-review of animal studies, increased water intake led to increased lipolysis and a loss of fat.
Drinking water can also help with weight loss in other ways. It may suppress your appetite, boost your metabolism, and make exercise easier and more efficient, all of which could contribute to results on the scale. For example, being hydrated reduces the risk of things that can get in the way of a good workout, such as muscle cramps and fatigue. It also helps the lungs, heart, and other organs to work effectively as they ramp up activity during exercise.
The keto diet can cause symptoms of mild dehydration if water consumption is not properly managed. This is because the keto diet eliminates nearly all carbs from your daily diet, and carbs and their salt content hold onto a lot of the water that you drink. The keto diet also encourages dieters to eat whole foods that naturally have a lower sodium content. This sodium and salt are vital for retaining water. Without these carbs, drinking water will not have the same effect, and it will be expelled through sweating or urination. Therefore, it is important to make sure you are drinking enough water while on the keto diet.

How much water to drink depends on body type
Staying hydrated is crucial for any diet, but it becomes even more important when following a ketogenic diet. This is because the keto diet eliminates almost all carbohydrates, which typically retain water in the body. As a result, keto dieters need to pay close attention to their water intake to avoid dehydration.
So, how much water should you drink on a ketogenic diet? While there is no one-size-fits-all answer, a general formula can be used to estimate daily water intake. This formula suggests choosing between 50% to 100% of your body weight in pounds and drinking that number of ounces of water daily. For example, if you weigh 160 pounds, drinking 80 ounces (or 10 cups) of water per day would be sufficient. However, this is just a starting point, and several external factors come into play.
One important factor is exercise. If you engage in regular physical activity or live in a hot climate, you will likely need to increase your water intake. The American College of Sports Medicine recommends adding 12 ounces of water for every 30 minutes of planned exercise, with the possibility of needing even more if you're exercising outdoors in hot weather. Additionally, age, weight, and diet can also influence your water needs.
It's worth noting that while plain water is essential, you can also get fluids from other sources. Coffee, tea, juice, milk, fruits, and vegetables all contribute to your daily hydration needs. However, water-rich foods like bone broth, avocado, and most vegetables are especially beneficial on the keto diet, as they provide hydration while being low in carbohydrates.
To ensure optimal hydration, it's recommended to drink before you feel thirsty and to monitor your urine color. If you're adequately hydrated, your urine should be colorless or a very pale yellow. Headaches, dizziness, and dark yellow urine are signs of dehydration, indicating the need to increase your water intake.

Other liquids and foods can also keep you hydrated
Staying hydrated is crucial during any diet, but especially so for the ketogenic diet, as it can cause mild dehydration. This is because the keto diet involves eliminating most carbohydrates, which hold onto a lot of water.
However, staying hydrated doesn't have to mean just drinking plain water. Coffee, tea, and flavoured still or sparkling water are all hydrating. In fact, your body can get about 20% of the water it needs from food. Raw fruits and vegetables are ideal sources of hydration, as they have high water content, as well as fibre, vitamins, and minerals.
Fruits and vegetables with a water content of more than 80% include:
- Cucumbers
- Watermelon
- Tomatoes
- Strawberries
- Oranges
- Grapes
- Celery
- Bell peppers, especially green ones
- Asparagus
- Cabbage
- Cauliflower
- Mushrooms
- Spinach
Other hydrating foods include olives, pickles, and bone broth. In addition to water, you can also drink milk, coconut water, and fruit juice to stay hydrated. Sports drinks can also be hydrating, especially if you are an athlete, as they contain electrolytes, which help your body retain water.
