How Much Water Weight Will I Gain After Keto

Following a ketogenic diet can lead to significant weight loss due to the body’s shift into a state of ketosis. However, many individuals wonder about the potential water weight gain that may occur after transitioning off the keto diet. In this article, we will explore the factors that contribute to water weight gain after keto and provide valuable insights to help you understand and manage this process.

Understanding Water Weight

Water weight refers to the temporary increase in body weight due to fluid retention. It is important to note that water weight is different from fat weight. While fat weight is a result of excess calories consumed, water weight can fluctuate due to various factors such as diet, hormones, and sodium intake.

The Role of Ketosis in Water Weight Loss

When following a ketogenic diet, the body enters a state of ketosis, where it primarily burns fat for fuel instead of carbohydrates. This process leads to a significant reduction in stored glycogen, which is the body’s primary source of energy derived from carbohydrates. As glycogen is depleted, the body releases water that was previously stored with it, resulting in initial water weight loss.

Factors Influencing Water Weight Gain After Keto

While transitioning off the keto diet, it is common to experience a temporary increase in water weight. Several factors contribute to this phenomenon:

  • Carbohydrate Intake: Increasing carbohydrate consumption after a period of low-carb intake can cause the body to replenish glycogen stores. For every gram of glycogen stored, the body retains approximately 3 grams of water. This can lead to a noticeable increase in water weight.
  • Sodium Intake: Consuming high amounts of sodium can cause water retention. Processed foods, which are often high in sodium, may be reintroduced after the keto diet, leading to an increase in water weight.
  • Hormonal Changes: Hormonal fluctuations, particularly in women, can influence water retention. Changes in estrogen and progesterone levels during the menstrual cycle can lead to temporary water weight gain.
  • Exercise and Muscle Glycogen: Engaging in intense exercise or strength training can cause the muscles to store glycogen. As mentioned earlier, glycogen is stored with water, resulting in an increase in water weight.

Managing Water Weight Gain After Keto

While water weight gain after keto is temporary, it can be frustrating for individuals who have experienced significant weight loss during their ketogenic journey. Here are some strategies to manage and minimize water weight gain:

  • Gradual Carbohydrate Increase: Instead of reintroducing carbohydrates abruptly, gradually increase your carbohydrate intake over a few weeks. This allows your body to adjust and minimize the impact on water weight.
  • Monitor Sodium Intake: Be mindful of your sodium consumption, especially when consuming processed foods. Opt for whole, unprocessed foods and season your meals with herbs and spices instead of salt.
  • Stay Hydrated: Drinking enough water can actually help reduce water retention. When the body is adequately hydrated, it is less likely to hold onto excess water.
  • Engage in Regular Exercise: Regular physical activity can help maintain muscle glycogen levels and promote overall fluid balance in the body.
  • Manage Stress Levels: High levels of stress can contribute to water retention. Incorporate stress management techniques such as meditation, yoga, or deep breathing exercises into your routine.

Frequently Asked Questions (FAQ)

1. Will I gain back all the weight I lost on keto?

Water weight gain after keto does not necessarily mean you will regain all the weight you lost. It is important to differentiate between water weight and fat weight. By following a balanced diet and maintaining a healthy lifestyle, you can prevent significant weight regain.

2. How long does water weight gain last after keto?

The duration of water weight gain after keto varies from person to person. It can last anywhere from a few days to a couple of weeks. By implementing the strategies mentioned earlier, you can help minimize the duration and impact of water weight gain.

3. Can I prevent water weight gain after keto?

While it may not be possible to completely prevent water weight gain after keto, you can take steps to minimize its impact. Gradually reintroducing carbohydrates, monitoring sodium intake, staying hydrated, and engaging in regular exercise can all contribute to managing water weight gain.

4. How can I differentiate between water weight and fat weight?

Water weight is temporary and can fluctuate rapidly, while fat weight is a result of excess calorie consumption and takes longer to accumulate or lose. Monitoring your weight over time and considering other factors such as body measurements and how your clothes fit can help you differentiate between the two.

5. Should I be concerned about water weight gain?

Water weight gain after keto is a normal physiological response and is not a cause for concern. It is important to focus on overall health and well-being rather than solely on the number on the scale.

6. Can I continue to lose weight after water weight gain?

Yes, after the initial water weight gain, it is possible to continue losing weight by following a balanced diet and maintaining an active lifestyle. Consistency and patience are key to achieving sustainable weight loss.


Water weight gain after transitioning off the keto diet is a common occurrence due to factors such as increased carbohydrate intake, sodium consumption, hormonal changes, and exercise-induced muscle glycogen storage. By implementing strategies such as gradual carbohydrate increase, monitoring sodium intake, staying hydrated, engaging in regular exercise, and managing stress levels, individuals can minimize the impact of water weight gain. It is important to remember that water weight is temporary and does not necessarily indicate fat weight regain. By focusing on overall health and maintaining a balanced lifestyle, individuals can continue to achieve their weight loss goals even after experiencing water weight gain.
