How Many Calories Are in a Glass of Water?
Absolutely zero. A standard glass of water, whether it's tap, filtered, or bottled, contains 0 calories. This makes it one of the healthiest and most essential beverages for the human body.
Unlike juices, sodas, or flavored drinks, water has no sugar, carbohydrates, fats, or proteins. It does not contribute directly to your calorie intake, which is why it’s often recommended as a primary drink for those focused on fat loss or maintaining a healthy lifestyle.
Why Water Has No Calories
Water is composed solely of hydrogen and oxygen—H2O. Since it contains no macronutrients, it doesn’t provide energy (calories) to the body. However, that doesn't mean it doesn't do anything. In fact, water is a vital player in nearly every biological function.
From regulating body temperature to aiding in cellular metabolism, water is indispensable. It’s involved in digestion, blood circulation, toxin removal, and even brain function.
7 Powerful Benefits of Drinking Water

- Before bed (lightly): Prevents night dehydration but avoid too much to prevent interrupted sleep.
