Drinking a Gallon of Water a Day to Lose Weight

The total body water or fluid contributes to about 55-75% of the entire body weight. This exceptionally high percentage is enough to suggest how important water is for our survival. Adequate water supply can help you in reducing body weight along with several other health benefits. In fact, based on a recent study, you can lose up to 10 pounds of body weight each year if you drink 1 gallon of water a day.

Is Drinking a Gallon of Water a Day Alright?

Yes, it’s all right to drink a gallon of water gradually in a day. Human body has distinct requirements that are unique to every individual. In other words, every individual should consume fluids according to their activity status and body requirements.

Based on clinical data, an average male requires 13 cups of fluid each day and an average females require at least 9 cups per day in order to maintain steady metabolism. If you have a dynamic lifestyle, you may require more than the suggested intake. The suggested intakes may also vary depending on the climate, overall health and certain physiological situations (such as pregnancy). There is no harm in taking more than the suggested amount.

How to Lose Weight by Drinking a Gallon of Water a Day

Drinking more water can help a great deal in reducing body weight in two ways: firstly, suppress the hunger so your stomach is constantly full with fluid and you feel less hunger; secondly, your body allows the releasing of retained fluids from cells while digestion and it happens when your body has enough water.

By the following steps, you can achieve the benchmark of drinking a gallon of water a day:

1. As soon as you wake up, drink 2 glasses (16 ounces) of water to flush out the waste in your body.

2. Before starting your breakfast, have a glass of water. It will keep you hydrated even at the start of the day.
