Drinking water makes you lose weight.
Water does not cause you to lose weight, however it does keep you hydrated, and might help you to snack less. Water is essential for good health and well being as a large portion of your body is made up of water. Thirst can often be mistaken for hunger, as such being thirsty can occasionally lead to snacking, if you feel hungry soon after eating a meal it may just be thirst so have a glass of water and see if the hunger subsides. Your goal should be to drink around two liters of fluids a day.
