Question: do you have to drink a lot of water to lose weight?
Answer: Studies of older adults have shown that drinking water before each meal may increase weight loss by 2 kg (4.4 lbs) over a 12-week period ( 4 , 11 ). In one study, middle-aged overweight and obese participants who drank water before each meal lost 44% more weight, compared to a group that did not drink more water ( 4 ).
