There are 128 ounces in a gallon, so to drink a gallon of water in one day, you would need to drink 16 8-ounce glasses. It seems like an impossible task, but recent research suggests that a person who drinks a lot of water every day enjoys better digestion and may lose weight quickly. According to Dr. Brenda Davy, a professor of nutrition at Virginia Tech University, people who drink a couple glasses of water before a meal tend to eat up to 75 fewer calories at that particular sitting. Even though this amount might not seem impressive at first, Davy claims it can help you lose 10 pounds or more within a year. So what does drinking a gallon of water in one day look like? Ounce by ounce, this is a lot of liquid to ingest -- and a lot of bathroom trips to make -- but spread throughout the day, it's an achievable goal.
Drink two glasses of water right after you wake up. Make sure each glass holds approximately 8 ounces or water. An easy way to accomplish this is by filling a 16-ounce water bottle and placing it beside your bed each night so you always have easy access to water.
Have one glass of water while you are preparing breakfast and getting dressed. Then, during breakfast, drink an additional glass, which will help you digest your meal better and ensure that you start the day well hydrated. Keep a designated 8-ounce glass of water that you use when at home. Even decorating it can help you both remember to keep drinking and make the experience that much more special.
Enjoy three glasses of water in the period before lunch. If you exercise during this part of the day, drink additional water to replenish the reserves you expel through perspiration. Have two glasses of water with lunch. If your lunch is protein- or fiber-heavy, having this amount of water will also help digestion. Remember to keep a filled water bottle with you at all times, wherever you go, so that you can continue hydrating throughout the day.
Consume at least three glasses of fresh water in the period between lunch and dinner. Add a slice of lemon, some fresh mint or cucumber slices to give your drink a refreshing flavor and add variety, but don't add sugar, which reduces the effectiveness of all of the hydrating you're doing.
Have a glass of water while you are preparing dinner then wash down dinner with another two glasses of water. You should have consumed nearly a gallon of water by this time. It is important to drink the majority of your water before late evening to help reduce restroom stops during the night.
Instead of dessert or a late-night snack, have a warm glass of water, perhaps with some lemon or grated ginger, which can have a calming effect before getting ready for bed. It is easy to confuse the feeling of thirst with hunger, causing many people to overeat when they're actually just thirsty. Ending your day with a drink of water will help reduce late-night munching and facilitate digestion throughout the night.
