Drinking a large glass of water tricks the brain, making you feel full sooner. Although we may have heard this advice from friends and family to drink water before meals, the results of a scientific study have now shown for the first time what happens to the brain when you drink a large glass of water before eating. According to Express, a group of Dutch researchers conducted MRI scans of the stomach and brain of several individuals before and after drinking water and eating. The results showed that the stomachs of those who drank a full glass of water were twice as full as those who either did not drink water or drank a small glass. Meanwhile, the first group felt "fuller" and experienced less hunger compared to the other two groups. According to Standard, a part of the mid-brain of these individuals was also activated after drinking a large glass of water. The researchers believe that drinking a lot of water at the beginning of meals reduces appetite, and for those looking to lose weight, this is a simple and cost-effective method.
