drinking water can help someone to lose weight by replacing high calorie sodas and juices as a way to cut your daily calorie intake. it can help people to lose weight by helping you to feel more full when you eat because liquids fill up your stomach just as well as food. it can also help you to lose weight because fiber kind of soaks up water, if you're not drinking enough water for the fiber you eat, you'll get constipated. so by helping your bowels to keep on moving that reduces the weight in your intestines (and that bloated feeling).
water does not replenish any nutrients in your body, unless it specifically has certain minerals in it. the amount of these minerals would be so minor it is not good to consider it a dietary source. there can be trace minerals if it's natural water from the mountains or a well and that usually is what gives it a different taste that "pure" water.
the 8 glasses of water thing is highly debatable. increasing water intake does not necessarily flush anything out it just makes what you are already flushing out less concentrated. there are other mechanisms in our body that deal with removing unwanted materials. it's not like washing a car. the ideal amount of water intake varies by person to person and you only need to drink in what you are losing by sweating, urinating, crying, spitting and various other body fluid losses. secondly it doesn't all have to come from glasses of water. you absorb water by eating an apple or an orange, for example. the origin of this 8-glasses-a-day thing is very fuzzy. it is a conglomeration of science mixed in with public claims. in reality, we get almost all the water we need from the foods that we eat to meet the bare minimum for surviving. which would leave us with needing to drink only about 4 8-ounce glasses of fluid versus 8-10 for a moderately active person.
if you're not thirsty you don't need to drink, simple as that. if you're worried about your water levels, then just increase by 1 glass to help cover any gaps. our country is not in such a dire state of dehydration like water enthusiasts want you to believe. be reasonable.
