Tag: Dehydration on keto

Approximately 7-10% of the world's population is on a low-carbohydrate diet at any given time, and many of these individuals will experience noticeable changes in their urinary patterns when they enter ketosis.

Anecdotal reports suggest that some people in ketosis experience a strange sweet taste in their mouth. This odd sensation can lead to the perception that even plain water has a sweet, fruity, or metallic flavor. Understanding why this happens can provide insight into the metabolic changes occurring in your body during a ketogenic diet.

Studies have shown that a significant number of people on the ketogenic diet experience a collection of symptoms often termed the "keto flu". This is the primary reason why do I feel dizzy and lightheaded on keto diet, stemming from major physiological shifts as your body switches its primary fuel source from glucose to fat.

Approximately 25% of individuals transitioning to a ketogenic diet experience flu-like symptoms, and a feverish sensation is a common complaint. This discomfort, commonly known as 'keto flu', is a temporary reaction as your body shifts from burning glucose to fat for energy, triggering a cascade of metabolic changes that make you feel feverish on keto.

According to research, leg cramps are a common side effect for many people transitioning to a ketogenic diet. This unpleasant experience, often part of the so-called 'keto flu,' raises the critical question: does ketosis cause cramps, and if so, what is the connection?

Some people on a ketogenic diet report losing up to 10 pounds in the first two weeks, primarily due to water weight loss caused by the depletion of glycogen stores. This rapid fluid shift is a primary reason why you might feel significantly more thirsty on keto. But the thirst you experience is a complex physiological response involving more than just water loss.

According to a 2025 review in *Frontiers in Nutrition*, many individuals experience a collection of transient symptoms known as the 'keto-flu' during the initial phase of adopting a ketogenic diet. This phenomenon helps explain why you might feel so bad in ketosis and is a signal that your body is adapting to a new metabolic state.

When starting a ketogenic diet, the body undergoes a significant metabolic shift that can increase fluid and electrolyte excretion. So, what happens if you don't drink enough water on the keto diet? You risk experiencing everything from unpleasant 'keto flu' symptoms to more severe health complications that can derail your progress and well-being.
