Drinking plenty of water is commonly recommended in weight loss regimens; however, very limited scientific evidence is available to justify this. Here we studied the effect of drinking 1.5 L of water, over and above the usual intake on body weight, ...

2] showed that the sympathetic activation after water drinking might stimulate thermogenesis and increase resting energy expenditure by 30% within 10 min of drinking the water (peaked at 30-40 min) and was sustained for over an hour. The water-induced thermogenesis was attributed to sympathetic nervous system activation because ingestion of a beta-adrenoreceptor blocker before drinking water almost completely abolished this response. Drinking water that had been heated to 37°C, attenuated the thermogenic response by 40%; which led to the suggestion that water-induced thermogenesis could be partly attributed to the energy cost of warming the water to body temperature. The authors extrapolated that increasing daily water intake by 1.5 L would augment energy expenditure by approximately 200 kJ/d.[
