If you’re trying to lose weight, drinking water before meals may help, suggests a British study in the journal Obesity.
Researchers assigned 84 obese people to either a “water preloading” group (who were instructed to drink 2 cups of water 30 minutes before meals) or an “attention” control group (who were told to just imagine their stomachs being full). All participants were counseled on general weight management practices, including diet and exercise.
After 12 weeks, the water group lost 3 pounds more on average than the control group, with the greatest weight loss (nearly 10 pounds) in those who reported water preloading before every main meal. But longer studies are needed to see “whether the short-term benefit of water preloading is maintained” over time, the researchers concluded.
