THE PEOPLE WHO DRANK WATER BEFORE ALL THREE MEALS LOST MORE THAN FIVE POUNDS TOTAL IN THE THREEMONTH STUDY PERIOD.
10 HEAD FOR THE WATER Obese participants instructed to drink two cups of water before meals for 12 weeks lost almost three more pounds than did those in a control group, in a 2015 study published in the journal Obesity. One (pretty obvious) reason? “Water fills your stomach and seems to increase satiety, which appears to lead you to eat less at your main meals,” says Helen Parretti, Ph.D., the lead study author and a lecturer at the University of Birmingham, in England.
