MICHAEL SMITH: It sounds too good to be true. Just drinking more water can help you lose weight.

But that's what researchers found. Drinking as little as 1% more water means you'll eat fewer calories. You'll also benefit from a drop in saturated fat, sugar, sodium, and cholesterol.

One extra cup of H2O in a day will save you 68 calories. And you don't have to do this every day to get the savings. Drink three extra cups, and you'll cut your calorie intake by 205.

To put it in perspective, that's as many calories as you'd burn if you walked two and a half miles.

Now, you can't just lie around on the couch all day and chug a gallon of water instead. You still need to keep up those healthy habits. And no word on what happens if you drink more than three cups, except for spending a lot of time in the bathroom.

And this doesn't mean you can eat more, just that you're more likely to eat less. But that walk to the water cooler gets you a lot further than you thought. For WebMD, I'm Dr. Michael Smith.
