Water Fast
A period of consuming only non-caloric liquids to trigger metabolic change.
A water fast removes all calories and forces the body to rely fully on stored energy. This can accelerate fat use but also increases physical and mental demands. Preparation and recovery are important to avoid discomfort. It is a more advanced approach and should be used carefully.
