Cold Water Diet: A Hoax?

For someone who says she doesn’t “diet,” my friend reports using a dieting trick. Her secret is the cold water diet. So does it work? Theoretically yes, practically not very much. Yes it’s true that you’ll burn 4 % more calories drinking ice cold water over the course of an hour, and at 3 glasses of ice cold classes of water per day, you could theoretically lose 2-3 pounds after a year. Drinking room temperature water will not increase your metabolism, so there is a small theoretical benefit to cold water. I say small because you’re better off concentrating on your diet than drinking cold water.
