4. Not enough salt
The state of ketosis (fat burning) results in the body producing more urine, so anyone on a keto diet has to be aware of their hydration levels.
Experts say: “Early signs that you may not be hydrated include brain fog, feeling lightheaded, feeling thirsty, dry mouth, and feeling nauseous.”
This is also known as “keto flu” and doesn’t happen to everyone following a keto diet.
In a bid to rehydrate and retain water, electrolytes found in sea salt and Himalayan salt can be incorporated into the diet by adding a pinch of the salts to meals.
Drinking two litres of water a day can also help with hydration.
