A member asked:
Should a person be drinking eight 8 oz glasses a day? shouldn't this be determined by body weight instead?
A doctor has provided 1 answer
Yes: 8x8 oz glasses of fluid/water is 64oz = 2qt/day. This is for an average size considered to be 154lb. So intake should be about 0.42oz/lb/day. To adjust for 110lb person it would be minimum of 46oz per day. For 220lb person minimum would be 92oz. This amount has some extra fluid to take care of unexpected losses like increased sweating or less water in food one eats. Minimum intake 0.25oz/lb/day.
