The "8 glasses of water a day" rule is a myth. Water requirements vary wildly based on your body weight, physical activity, and local climate. Drinking too little impairs fat loss and cognitive function, while drinking too much can lead to hyponatremia.
Use the calculator below to find your specific hydration target based on authentic World Health Organization (WHO) physiological guidelines.
Why hydration impacts weight loss
Your kidneys require sufficient water to function. When dehydrated, the liver has to step in to help the kidneys, which severely limits the liver's ability to metabolize stored fat. Furthermore, thirst is frequently confused with hunger by the brain.
