Introduction
Could drinking extra water helpus lose weight? Epidemiologicaldata indicates water drinkers havea 9% (194 kcal/d) lower caloricintake than non-water drinkers.This reduction favors older peoplewho are more likely to be onprescription medications. If waterworks to establish weight controlthis is problematic for trials thatuse water as an inactive control.
ObjectivesTo run a self-recruited fully onlinerandomized trial to investigateif drinking water preventsweight-gain.
To explore participant engagementand barriers, add to onlinetrials methodology and to offerinteractive just in time publicresearch training.
