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.

There are some considerations, and the intervention would be contraindicated in patients with congestive cardiac failure, and in those with severe renal impairment.
