2 dl of water before a meal will make you eat 100 cal less. This is according to a study in US. Yhe people who had 2 dl (close to a cup) of water before their meal lost two kilos in three months.
The study featured 48 adults between the ages of 55 and 75 over a 12-week period.
Half of the group were on a low-calorie diet and also drank two dl of water prior to each meal, while the other 24 had the same diet and got water as well, but weren't told specifically when to drink it. When the weeks were over, people in the first group had lost an average of about seven kg , as opposed to the average of five kilos people in the second group shed. In addition, a year after the study, those who drank the water prior to the meals were doing a better job keeping the weight off.
Of course their weight loss was due to eating less, but since both groups had the same diet, the group drinking water lost more. The theory is that drinking water first makes you better prepared to eat a little less.
The results could also be age-specific. As you age, the digestive process slows down, meaning you feel full longer the older you are. But, as Brenda Davy, one of the study's researchers, notes, drinking more water could still help in dieting, no matter what your age. That's because it can increase metabolism, thus helping to burn more calories, or it can act as a replacement for other drinks that have calories.
