Keto Water Weight Loss: What's The Deal?

do you lose water weight first on keto

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 burns fat for energy instead of carbohydrates. 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 the body enters ketosis and starts burning through its carb stores, it also releases and eliminates the water that was bound to those carbs. This can result in dramatic weight loss during the first week or two of the keto diet, with some people reporting losses of anywhere from 1 to 10 or more pounds. However, it's important to note that this early weight loss is mostly water weight, and the actual fat loss occurs once the body is fully in ketosis.

Characteristics Values
Weight loss during the first week of keto 2-10 pounds
Reason for weight loss during the first week Water weight loss, not fat loss
Why does water weight loss happen? Carbs need water to stay in the body. When the body doesn't use glucose immediately, it stores it as glycogen in the muscles, and glycogen binds to water.
Who is likely to lose the most water weight in the first week? People with a higher overall weight initially
Who is likely to lose the least water weight in the first week? People with a lower initial body weight
What happens after the first week? Weight loss will usually happen at a slower, more steady pace.
Average weight loss after the first week 1-2 pounds per week

The keto diet involves limiting carbs and eating healthy fats, veggies, and quality meats

The keto diet is a low-carb, high-fat diet that involves drastically reducing your carbohydrate intake and replacing it with healthy fats. The diet typically limits carbs to 20-50 grams per day and encourages filling up on fats such as meat, fish, eggs, nuts, and healthy oils.

On the keto diet, it is important to base your meals around whole, single-ingredient foods. Meat, fish, eggs, butter, nuts, healthy oils, avocados, and low-carb veggies should make up the majority of your diet.

  • Breakfast: Veggie and egg muffins with tomatoes
  • Lunch: Chicken salad with olive oil, feta cheese, olives, and a side salad
  • Dinner: Salmon with asparagus cooked in butter
  • Breakfast: Egg, tomato, basil, and spinach omelet
  • Lunch: Almond milk, peanut butter, spinach, cocoa powder, and stevia milkshake with a side of sliced strawberries
  • Dinner: Cheese-shell tacos with salsa
  • Breakfast: Nut milk chia pudding topped with coconut and blackberries
  • Lunch: Avocado shrimp salad
  • Dinner: Pork chops with Parmesan cheese, broccoli, and salad

The keto diet offers many health benefits, including weight loss, improved metabolic health, and lower risk factors for certain diseases. However, it is important to consult your doctor before starting the keto diet, as it may have some side effects and is not suitable for everyone.

The body stores glycogen when you consume lots of carbohydrates

The glycogen stored in your muscles and liver is bound with water, and when you burn through these stored carbs, this water is excreted in your urine or sweat. As a result, after starting keto, you may find yourself urinating more frequently and feeling thirstier than usual. This weight loss can vary depending on your size and how much water weight you're carrying. 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. On the other hand, those with a lower initial body weight may lose as little as a single pound in their first week or two.

The amount of water weight lost during the early days of ketosis is subjective and depends on your previous carb intake, your overall weight, and even your daily water intake. Most people talk about losing 6-10 pounds of water weight in the first week or two of ketosis or after an extended water fast. However, it's important to note that this water weight loss tends to slow down as your body adjusts to being in ketosis and deplete its glycogen stores.

Once you've burned through your glycogen reserves, your body will transition to burning fat for energy. This is when you'll start to see more lasting weight loss and experience the serious health benefits associated with the keto diet. Many people will find that they steadily shed around two pounds per week once the water weight is lost. While it can be motivating to see the number on the scale change rapidly during the initial water weight loss phase, it's important to stick with the keto diet even after this initial period to achieve long-term weight loss and health benefits.

The glycogen is stored in a 1:3 ratio of glycogen to water

When you start a keto diet, the first weight you lose is typically water weight. This is because the keto diet involves limiting your carb intake, which means your body burns through the glycogen stored in your muscles and liver.

Glycogen is a form of glucose, which is your body's main source of energy. Your body stores glycogen in your liver and muscles, bound with water in a ratio of 1:3 (glycogen to water). When you restrict carbs, your body rapidly burns through this stored glycogen, and the water that was bound to it is excreted in your urine or sweat. This leads to a noticeable weight loss during the initial stages of the keto diet, which is mostly water weight.

The larger you are, the more water weight you're likely to lose after starting keto. However, it's important to note that this initial weight loss is not fat loss. Once you enter ketosis, your body starts burning stored body fat more efficiently, and that's when you'll see more significant fat loss.

Ketosis is a metabolic state where the body uses ketones as its primary source of fuel

When you restrict carbohydrates on a keto diet, your body burns through the stored carbs in your liver and muscles, known as glycogen. Glycogen is bound to water in the body, typically at a ratio of 1:3. As your body depletes its glycogen stores, it also releases and excretes the water bound to it, leading to a rapid loss of water weight. This water weight loss is often the reason for the dramatic weight loss observed during the initial stage of a keto diet.

The shift from burning glycogen to using ketones as the primary fuel source usually takes less than a week but can vary depending on individual factors. During this transition, it is common to experience increased thirst and a need to urinate more frequently as the body is flushing out excess water.

While the initial weight loss on a keto diet is primarily attributed to water weight loss, once the body enters ketosis, it becomes more efficient at burning stored body fat for energy. As a result, weight loss may slow down, but it is more likely to be a loss of fat rather than water. This stage of the keto diet is often considered more beneficial for long-term weight loss and overall health.

It is important to note that the amount of water weight lost during the early days of ketosis can vary based on factors such as previous carb intake, overall weight, and daily water intake. Additionally, 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 or nutritional regimen.

The keto diet is a high-fat, low-carb diet that was originally devised to treat epilepsy

When first starting the keto diet, the body initially burns through the carb stores in the liver and muscles, called glycogen, which is bound to water in a 1:3 ratio. As a result, the water bound to glycogen is excreted through urine or sweat, leading to a rapid loss of water weight. This can result in dramatic weight loss during the transition period, with some people reporting losses of anywhere from 1 to 10 or more pounds within the first week. However, it's important to note that this early weight loss is primarily due to water loss rather than fat loss.

After the initial water weight loss, the body enters a state of ketosis and starts burning fat for energy. This is when individuals on the keto diet start to experience more sustained and lasting weight loss. The rate of weight loss may slow down during this stage, but it is more likely to be a loss of fat rather than water.

While the keto diet can lead to weight loss, it is important to approach it with a healthy mindset and focus on overall health and well-being. It is not recommended to use extreme measures such as dehydration to try to trigger a "whoosh" effect, as this is not a safe or effective way to achieve long-term weight loss.

Frequently asked questions

The keto diet is a high-fat, low-carbohydrate diet that was originally devised to help treat epilepsy. It involves limiting your carb intake to a maximum of 50 grams per day, or 25 grams of net carbs (total carbs minus fibre).

The keto diet leads to weight loss by forcing your body to burn fat for energy instead of carbohydrates. This is known as ketosis. When you restrict carbs on keto, your body rapidly burns through glycogen, the stored carbs in your liver and muscles, which is bound to water. After your glycogen stores are depleted, you start to burn fat.

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. Most people talk about losing 6-10 pounds of water weight in the first week or two of ketosis or after an extended water fast.

Getting into ketosis usually takes anywhere between 2-7 days. Weight loss will usually happen at a slower, more steady pace after the first week or two. Many people will find that they steadily shed around two pounds per week once the water weight is lost.
