20 Habits Skinny People Live By

Skinny Habit #8: Drink water

Almost 60 percent of your body is water, which makes it vital to every important metabolic process. In one study of 173 overweight women, those who added 1 liter of daily water to their diets lost five extra pounds over the course of a year, and if you time it right, the effects can be even greater. When researchers from Virginia Tech had subjects drink two glasses of water before each meal, they found that those subjects lost 30 percent more body fat over 12 weeks. That said, making beverage blunders is one of the easiest ways to gain belly fat—as the average American drinks 450 sugar-loaded calories a day. Replace half of what you drink with water and you'll save 23 pounds per year!
