The Best Diet Drink Is...The most effective diet drink is cheap and plentiful: tap water. If you want to cut calories to lose weight, drink more water. That's the word from researchers at the University of Illinois Urbana-Champaign, who found that adults who increased their daily water consumption by as little as one percent also slightly cut their daily consumption of sugar, salt, saturated fat and cholesterol.
The study: Led by Ruopeng An, a professor of kinesiology and community health, the team analyzed the eating habits of 18,300 adults, all of whom were part of a U.S. government-led study. Each participant reported everything he or she ate or drank over the course of two days; the two days were not consecutive, but rather separated by three to 10 days.
The Illinois researchers then calculated the amount of plain water consumed daily as a percentage of each person's dietary water intake from food and beverages combined.
While the beneficial effects of increased water consumption were most notable among men as well as young and middle-aged adults, the impact remained regardless of race/ethnicity, education, income levels and body weight status.
The study findings were reported in the Journal of Human Nutrition and Dietetics.
