How much water per day does a person require? It depends on the characteristics of an organism, on its weight, and physical activity. Today, according to most scholars, the rate of water consumption for adults is about 30-40 ml per kilogram of the body weight.
Partly we get the liquid necessary for the body with food products. Other beverages such as juices, tea and coffee are liquid, too. Anyway, one thing is certain: pure, refreshing water is an ideal choice out of all the drinks, especially for those losing weight, because it contains no calories.
There is even a special “water” diet which essentially is a simple low-calorie diet that supposes consumption of large quantities of water, up to 4 liters. Although, as all diets, the water diet has very significant disadvantages. If a person drinks 4 or more liters of a liquid a day, necessary mineral substances are washed away from the body. Intracranial pressure increases, which causes severe headaches.
Yes, excessive water consumption dulls the feeling of hunger, thus helping to lose weight. The sense of saturation actually occurs thanks to water, but it lasts only for a short time. And the harm caused by attempts to replace the food with water can be quite significant.
So it is not worth it to replace food with water! Water will not help us get rid of the false hunger and excessive appetite.
