How Much Water You Should Drink For Weight Loss?

Water is an essential part of your diet that often goes overlooked when talking about daily nutrient intake. Your body depends on water for a number of physiologic functions, and without it, you could not survive.

Water is necessary to digest foods, remove wastes from your body, maintain a normal body temperature, protect your organs and tissues, carry blood throughout your circulatory system, and lubricate your joints.

According to the U.S. National Academies of Sciences, Engineering, and Medicine, adequate daily fluid intake is about 3.7 liters of fluids a day for men (15.5 cups) and about 2.7 liters of fluids a day for women (11.5 cups).

How Much Water Per Day Will Help You Lose Weight?

However, this will vary based on body weight and physical activity. For instance, individuals who are more active lose more fluids through perspiration and require higher amounts of water to maintain adequate hydration.

Similarly, people who live in warmer climates require more fluid intake on a daily basis. If you lose fluid through illness, such as gastroenteritis or a urinary tract infection, you will need to drink more water to replace these losses.

Similar to how we need to maintain a calorie balance every day to maintain our current weight, the amount of water we drink or consume each day needs to match the amount of water that our bodies lose.

On the other hand, if this same person exercises for 60 minutes and spends another 30 minutes outdoors in the heat, they would need to drink an additional 36 ounces of water, bringing their total water consumption to 126-216 ounces of water.
