The human body is almost 70 percent water, according to David MacCaulay, author of the "The Way We Work." Water is necessary for life itself. Some in the field of fitness also believe that water can help us lose weight. Some even claim that the temperature of the water can make a difference in how we burn calories. As it turns out, the temperature of the water may make a tiny difference. But the most important thing is drinking it.

Warm Water and Calories

Water is a negative-calorie beverage. It delivers zero calories yet uses calories to process. Drinking an 8-oz. glass of warm water burns about eight calories, with cool and cold water burning slightly more, according to celebrity personal trainer Bill Phillips. Although eight calories per glass doesn't sound like much by itself, that adds up to hundreds of calories per week at the recommended eight glasses per day.

Snack Prevention

The diet resource website Weight Loss for All reports that drinking water can help fight snacking, hunger and food cravings. It recommends drinking a glass of water as a first response to any kind of eating impulse. This fills your stomach with a zero-calorie substance, helping you feel full until your allowed eating time. Although Weight Loss for All makes no distinctions concerning temperature, fitness coach Ben Cohn suggests that warm water often tastes worse than cold water and may further reduce your appetite.

Portion Control

Dr. Melina Jampolis, physician and diet correspondent for, reports that drinking water before a meal can help you eat less. According to the American Dietetic Association, people who drink a glass of water before eating consume an average 75 fewer calories per meal. Dr. Jampolis does the math for you, reporting that that ads up to 14 1/2 pounds over the course of one year. Neither Dr. Jampolis nor the ADA report a distinction between temperatures of the water.

Water vs. Other Drinks

Willet recommends water as best not only for weight loss, but also for overall health. Water is exactly what your body needs, without adding calories, sweeteners or chemicals. In terms of weight loss, water is much better than fruit juices, sodas or sweetened coffee and tea.

Does Drinking Warm Water Help You Lose Weight?

The majority of research indicates that drinking water can help you lose weight. But it won't burn enough calories to create significant results by itself. Phillips recommends drinking water as an adjunct to a more aggressive weight loss plan. On the subject of warm water vs. cold water, Phillips notes that cold water burns slightly more calories than warm, but overall the temperature either doesn't matter or hasn't been sufficiently researched.
