Heres a tip I found
Ice Water -
High water intake reduces fat deposits and rids the body of toxins. Simply drinking eight 16 oz. glasses of water throughout the day, cooled to 40 Fahrenheit, will burn 200 calories; that's equivalent to running 3 miles! Ice water will burn more calories since your metabolism will increase to warm the water to body temperature. It is also very effective for reducing cravings. If you're not a water fan, we suggest you experiment with purified, spring or reverse osmosis water. If you're still not convinced, add a little juice for flavor. Don't drink Ice Water with meals as it dilutes digestive enzymes. A little warm water or herb tea is a good choice then.
