In plain English

Drinking an extra 1.5 liters of water each day for six weeks lowers fasting blood glucose levels in people who are moderately dehydrated.

See the scientific wording

Increasing daily water intake by 1.5 liters for six weeks reduces fasting plasma glucose in moderately dehydrated individuals.

Why this might work

Drinking more water lowers the body's stress hormone signal, which tells the liver to stop making so much sugar, leading to lower blood sugar levels in the morning.
