Keto flu usually only lasts a few days, but some people might have symptoms for a week. When you go low carb, your body releases water
and loses electrolytes like sodium and potassium. If you don’t drink enough water and replenish this loss in electrolytes, you risk dehydration and symptoms of the keto flu . Stay Hydrated and Replenish ElectrolytesDehydration holds you back from feeling energized and causes symptoms similar to the keto flu, such as brain fog, fatigue, and muscle cramps. Make sure you’re drinking enough water to stay hydrated, and use an electrolyte powder in your drink for added minerals. Consume a mineral-rich, well-formulated ketogenic diet and fill your plate with magnesium
and potassium-rich foods like avocado and fish. Keto dieters often use more salt on their food to obtain sufficient sodium and trace
minerals. Use a high-quality salt like a Celtic sea salt or an Arctic salt, and happy salting!  Eat More CaloriesKeto helps you stay satiated, so you don’t feel as hungry as when you were eating a high carb diet. Ketosis accelerates your metabolism, and you burn around 300 more calories daily on a keto diet . On keto, you also burn more body fat, which is positive for weight loss. However, it’s easy to undereat on keto, and consuming too few calories can make you feel fatigued because you don’t have the caloric energy to function properly.
