Abstract
In normal men (no. not stated), drinking of water while fasting resulted in only small changes in blood sugar conc. and blood volume, and all the water was excreted in a few hours. Taking glucose with the water (400 gm. glucose in 2400 gm. water in 8 hrs.) resulted in marked increase in blood volume and in water retention, with an increase of about 1 kgm. in body weight.
