Even mild dehydration impairs memory, reasoning, and cognitive function, causes unnecessary fatigue, and makes you feel generally lousy. Eating keto changes the way your body process water and electrolytes sodium, potassium, and magnesium. Here are 5 things you need to know. Dehydration is a known side effect of ketogenic diets, for a couple reasons. For example, on keto, you excrete more salt more on this below. The more salt you lose, the less water you retain. At the beginning, many people also excrete a lot of excess ketone bodies, which is dehydrating. Basically, people eating keto need to drink more water to stay properly hydrated than people on other diets.

This may reduce or eliminate side effects within minutes.
