Losing weight with water

This 20-ounce cola packs a big punch of sugars - about 16 teaspoons. Overall, sugary drinks account for roughly 7% of all calories consumed in the U.S. and offer next to nothing in nutritional value.

"I do know that soda is not the best for you. And I do want to cut back."

"To be honest with you my daughter-in-law has told me that they're really bad for you. But, obviously today I'm enjoying one."

Some cities are adding hefty taxes to soda and other drinks hoping the higher price will cut down on consumption.

Consumer Reports Health Editor, Trisha Calvo said, "So-called 'sin' taxes can work. The World Health Organization has found that consumption of sugary drinks usually goes down when the taxes on them go up."

If you are trying to drink less soda to reduce sugar and calories, what you drink instead makes a big difference.

"No surprise here, water is best. If you trade one 20-ounce soda a day for water, you'd cut out 52 pounds of sugar a year," said Calvo.

That simple substitution can translate into a potential 14-pound weight loss in a year.

And research shows there are other important health benefits to water. It can alleviate headaches due to dehydration and help you fight fever and slow your heart rate.

During exercise, water is crucial to keep you cool and prevent dehydration. Experts can't explain why, but being well- hydrated can improve your mood. Hydrated runners also run faster.

Milk and orange juice can also be healthier substitutes for sugary drinks but also in moderation since they can pack a lot of calories.
