Water: What's In the Bottle?
Dieters are advised to drink a lot of water. Recent research revealed that the reason why water is so important in weight loss dieting is its sheer volume, which is the most important signal to the body indicating that it's time to stop eating your meal. Soups, and juices work just as well -- but they contain calories, which water doesn't. From this standpoint, it doesn't matter what bottled water brand you choose: purified, spring, or mineral, or even just tap water. Their safety standards are the same.
Purified water is a tap water, from which excess chlorine and chemicals have been removed along with excess minerals
Spring water is collected directly from its natural source, springs, that are not strongly mineralized
Mineral water is spring water that contains useful minerals and trace elements; it can have therapeutic qualities, for example, alkaline water can help in gastric ulcer or heart burn and acidic water can help in case of indigestion
In addition to its volume, mineral water containing significant amounts of calcium can aid in weight loss since there's scientific evidence that calcium is needed in the fat mobilizing process in adipose tissues.
