title: Pre-meal water consumption for weight loss.
abstract: Drinking 500 mL of water 30 minutes before each meal can be used in conjunction with a hypocaloric diet to lead to greater weight loss in overweight or obese middle-aged and older adults. Pre-meal water consumption for weight loss is an easy to implement intervention. It has NHMRC Level 2 evidence of efficacy and adverse effects are unlikely. There are some considerations, and the intervention would be contraindicated in patients with congestive cardiac failure, and in those with severe renal impairment.
