In what could fairly be called a watershed moment, scientists have
Yup, it's that simple. And you don't even have to buy the book.
In clinical trials, US researchers found that drinking a pint of water
before a meal leads to weight loss.
Dr Brenda Davy, an associate professor in human nutrition,
who led the study said: "We found in earlier studies that middle aged
and older people who drank two cups of water right before eating a meal
ate between 75 and 90 fewer calories during that meal.
"In this recent study, we found that over the course of 12 weeks,
dieters who drank water before meals, three times per day,
lost about 5 pounds more than dieters who did not increase
their water intake."
"People should drink more water and less sugary, high-calorie drinks.
It's a simple way to facilitate weight management," Dr Davy added.
While drinking water to lose weight is very much common sense,
Dr Davy said that there has been little scientific information on this topic.
Previous studies have suggested that drinking water before meals
reduces calorie intake, but according to Dr Davy this is the first
randomised controlled clinica trial to show that increasing the
amount of water that you drink water is an effective way to
The study tracked the weight of 48 adults aged
55 to 75, who were separated into two groups.
The first group drank two cups of water before meals and
the second group did not. All of the subjects ate a low-calorie diet
during the study.
Over the course of 12 weeks, the water drinkers lost around
15.5 pounds, while the non-water drinkers lost around 11 pounds.
Dr Davy said water may be so effective simply because it fills up
the stomach and has no calories, so that people feel full quicker
and eat less during meals.
She also added that replacing diet colas and other artificially
sweetened drinks with water also helps to cut calories,
and aids weight loss.
