How drinking water can lead to weight loss

Drinking plenty of water supports weight loss, but to what extent this actually happens and what can we really expect? A new study in the Journal of Human Nutrition and Dietics light a tip of the veil.


Drinking water reduces the total daily calorie intake

In the study (University of Illinois), the drinking habits of more than 18,300 adults were examined. Not only was water from the tap or bottle cooler, reduce the total daily calorie intake by 1 percent, also reduced drinking the intake of saturated fat, sugar, salt and cholesterol.


Water creates a lower intake of fat, salt and sugar

People who per day, one, two or three additional names cups of water (250 to 750 ml), reduced their total energy intake by 78 to 235 grams. They also consumed 5-18 grams less sugar and ate daily 7 to 21 grams less cholesterol.

“The impact of simple water intake was at every ethnicity, and every level of education, income and weight the same. These findings indicate that it may be enough to promote plain water instead of other beverages, with dietary interventions and campaigns. ”

Average daily participants drank about 1 liter of water, 30% more than their usual water intake. The decrease of 1% of total daily calorie intake amounted to a decrease of 8.6 calories per day. Or the daily decrease of 8.6 calories is enough to promote only water in nutrition interventions, such as the authors say, because not everyone will feel the same.

The results were greatest among men, and young and middle adults.
