Drinking 500ml water (2 cups) 30 minutes before each meal.
When combined with a hypocaloric diet, premeal water consumption leads to greater weight loss than a hypocaloric diet alone:
- approx. 2kg greater weight loss over 12 weeks
- 44% greater rate of weight loss.
Water is readily available and inexpensive. No studies have tested differences in tap, bottled, mineral or spring water.
