While experts may have different opinions on how much water you should consume, everyone agrees that we should keep our bodies hydrated with water each day. Water assists in all processes of human body – it keeps your blood flowing, keeps your joints lubricated, carries nutrients to all your cells and organs and cools down your body.
There is a common recommendation that tells you to drink eight large glasses of water each day. While there is no doubt that water is extremely important for human life there is no serious evidence that this amount of water is necessary for optimal health. In fact, kidney specialists will tell you that you need only about a liter of water per day to make up for losses – that’s about four eight-ounce glasses. You should also remember that some foods have lots of water in them. If you consume foods like fruits, vegetables and soups you probably need even less than four glasses. There are also other considerations such as climate and your activity level. The rule is to drink when you feel thirsty.
And still water can be a great help when you are trying to lose weight. Researchers found a clear association between drinking four to six glasses of water a day and weight loss. Apparently it works by simply taking up space, which would work with other low-calorie liquids. Coffee diet is a good example. If you are not drinking water you might be eating or drinking something else with a lot of calories. In addition water speeds up your metabolism and helps you burn calories faster. You can burn about 23 kcal for drinking 500ml of water. Here is the link to this study.
