Keto Diet: Water Weight Loss Explained

The keto diet is a popular choice for people looking to lose weight. It involves eating a low-carb, high-fat diet that induces ketosis, a metabolic state where the body uses ketones, broken down from dietary or stored body fat, as its primary source of fuel. While the keto diet can lead to weight loss, it's important to understand that much of the initial weight loss is due to water weight loss rather than fat loss. This is because when you restrict carbs, your body rapidly burns through glycogen, which is stored in the liver and muscles and bound to water. As a result, the water is excreted through urine or sweat, leading to a rapid drop in weight, often within the first week of starting the diet. However, this water weight loss is only temporary, and once the body enters full ketosis, the weight loss will likely slow down, but it will be more fat than water.

The keto diet can cause dehydration

The keto diet's initial weight loss is largely due to water weight loss. When entering ketosis, the body burns through glycogen reserves, which are bound to water. As a result, the water is released and excreted through urine or sweat, leading to frequent urination and increased thirst. This rapid water loss can contribute to dehydration if not properly managed.

The amount of water weight lost during the early stages of ketosis varies depending on factors such as previous carb intake, overall weight, and daily water intake. People with a higher initial body weight tend to lose more water weight in the first week, with the body flushing out about ten pounds of water weight. On the other hand, those with a lower body weight may lose as little as a single pound in the first week or two.

The keto diet's impact on hydration and water weight loss is important to consider. While the diet can lead to dehydration, proper management of fluid intake and electrolyte consumption can help mitigate this risk. Additionally, the initial weight loss due to water weight loss should not be the sole indicator of the diet's effectiveness, as it is not indicative of long-term weight loss.

The keto diet can lead to constipation

To prevent constipation while on the keto diet, it is important to ensure adequate fluid intake and include plenty of fibre-rich foods. Non-starchy vegetables, nuts, seeds, and low-carb fruits such as avocados and berries are good sources of fibre on the keto diet. Additionally, staying hydrated is crucial. Drinking enough water and consuming electrolytes like sodium and potassium can help prevent dehydration and maintain regular bowel movements.

It is worth noting that the keto diet may not be suitable for everyone, and it is always recommended to consult with a healthcare professional before starting any new diet, especially if you have any health concerns or are taking medications.

While the keto diet can lead to constipation, addressing these issues through proper hydration and fibre intake can help alleviate this problem.

The keto diet can cause an increase in urination

The keto diet can also cause dehydration, as the water that was bound to glycogen is lost through urination. It is important to drink plenty of water when on the keto diet to avoid dehydration.

In addition to increased urination, the keto diet can also cause other side effects such as bad breath, constipation, and diarrhea. These side effects are usually temporary and tend to go away once the body adjusts to burning fat for fuel instead of carbohydrates.

The keto diet is known for its weight loss benefits, and the initial weight loss is often attributed to the loss of water weight. However, after the first week or so, once the body enters a state of ketosis, fat loss can occur more easily.

The keto diet can cause an increase in thirst

The keto diet is a low-carb, high-fat diet that forces the body to burn fat for energy instead of carbohydrates. One of the main changes that occur in the body during the adaptation period is reduced insulin levels. Insulin influences how the kidneys manage sodium, prompting the body to excrete more sodium and water. Therefore, the change in insulin levels caused by the keto diet can result in the body expelling more fluids, making individuals thirstier and potentially dehydrated.

When you cut out carbohydrates from your diet, your body burns fat for energy, which causes your kidneys to excrete more water. This increased water excretion leads to dehydration, which, in turn, triggers your thirst.

Additionally, when you significantly reduce carbohydrates in your diet, your insulin levels decrease. Low insulin levels cause your kidneys to release sodium, which leads to an increase in urine production and further dehydration.

How to counteract dehydration

• Drink plenty of water and electrolyte-rich fluids.
• Consume fruits and vegetables with high water content, such as watermelon, cucumbers, and celery.
• Drink coconut water, which contains sodium, potassium, magnesium, and calcium.
• Consume more sodium, potassium, and magnesium-rich foods or supplements while ensuring adequate fluid intake.
• Monitor urine output and colour to check if you are drinking enough fluids.
• Try IV treatments to prevent dehydration.
• Eat more plant-based proteins like tofu or tempeh.

Symptoms of dehydration on the keto diet

• Increased thirst
• Dizziness or lightheadedness
• Dry mouth
• Dark-coloured urine
• Headaches
• Fatigue
• Muscle cramps

The keto diet can lead to weight loss slowing down

Glycogen is stored with water in your body, usually in a 1:3 ratio of glycogen to water. When you burn through these stored carbs, this water is excreted in your urine or sweat. This leads to dramatic initial weight loss, which is mostly water weight loss. However, once you enter ketosis and deplete your glycogen stores, your weight loss will probably slow down. At this point, you will be burning more stored body fat, which leads to more lasting weight loss.

The amount of water weight lost during the early days of ketosis varies depending on your previous carb intake, your overall weight, and even how much water you drink daily. People with a higher overall weight initially tend to lose the most water weight in the first week or so of starting the keto diet. As the body transitions from burning carbs, it may flush out about ten pounds of water weight. On the other hand, those with a lower initial body weight may lose as little as one pound in their first week or two.

Eventually, your weight loss may slow down or even stall for a while as your body adjusts to being in ketosis and is no longer shedding water as quickly. This is when you can focus on shedding fat over water, which leads to more lasting weight loss and has serious health benefits. Many people will find that they steadily shed around two pounds per week once the water weight is lost. It's important to stick with the keto diet during this time, even if the weight loss is not as rapid as it was in the early days.
