Big glass of water ‘helps fill you up’

Drinking a large glass of water with a meal really does trick the brain into thinking you are full, researchers say.

A new study has, for the first time, combined three sets of data to work out what happens when a large glass of water is drunk.

A team from Wageningen University in the Netherlands looked at stomach MRI scans, MRI scans of the brain and recorded how full people said they felt.
