Study Arms (2)

Ad libitum water intake

ACTIVE COMPARATOR

Ad libitum water intake, defined as intake guided by thirst to achieve a target urine osmolality \> 300 mOsmo/kg

Other: Ad libitum water intake

High water intake

ACTIVE COMPARATOR

Personalised daily water intake prescription to achieve target urine osmolality \< 270 mOsm/kg.

Dietary Supplement: High water intake

Interventions

High water intakeDIETARY_SUPPLEMENT

High water intake aimed at achieving an urine osmolality \< 270mOsmo/kg. Individualised prescription for each participant based on the free water clearance formula calculation.
