Though not everyone may experience this, it may be an indication of your body requiring more hydration and electrolytes.
When you are experiencing the state of ketosis, your insulin levels tend to be lower. When insulin in the body is low, your kidneys will excrete more water and sodium. This in turn, leads to frequent urination and creates the possibility for dehydration.

Ensure to be taking at least the recommended minimum amount of water daily of 0.5 ounces per pound of bodyweight. In addition, quality electrolytes will replenish minerals lost due to the diuretic effect of ketones, the main ones to consider are: sodium, potassium, chloride, calcium, and magnesium. This electrolyte is an excellent choice for consideration.
