Key result
Drinking 500 ml water increases energy expenditure ~24% vs saline in overweight or obese subjects.
Why the study?
The mechanisms underlying water drinking-induced thermogenesis in overweight or obese healthy subjects were unclear.
Does drinking 500 ml water increase energy expenditure in overweight or obese otherwise healthy subjects?
RCT (n=16)
randomized, crossover
Does drinking 500 ml water increase energy expenditure in overweight or obese otherwise healthy subjects?
Drinking 500 ml of water increases energy expenditure by 24% in overweight or obese subjects, likely mediated by osmosensitive mechanisms rather than gastric distension.
No takes yet. Share an insight, caveat, or question.
500 ml water may raise energy expenditure in overweight adults; hypothesis-generating and should not yet change practice.
Boschmann et al. (2007) conducted an RCT in overweight or obesity (n=16). Water vs. 500 ml isoosmotic saline or 50 ml water was evaluated on energy expenditure. Drinking 500 ml of water increased energy expenditure by 24% over 60 minutes in overweight or obese subjects, whereas 500 ml isoosmotic saline or 50 ml water had no effect.
