It’s often claimed that if you’re trying to lose weight, one of the things you should do each day is drink plenty of water – with some internet advice even suggesting this should be as much as a gallon (about 4.5 litres). The claim is that water helps burn calories and reduce appetite, which in turn leads to weight loss.
But while we all might wish it was this easy to lose weight, unfortunately there’s little evidence to back up these claims.
