Drink 2 cups (16 oz) of water before every meal: Science has proven that drinking 2 cups of water before every meal helps you to eat less during meal time and lose weight. If you do this three times daily - at breakfast, lunch, and dinner - you have already consumed 48 ounces of water. Morning and Night: Get into the habit of drinking one glass (16 oz) of water when you wake up and another 8 oz glass before you go to sleep every night. This will add another 24 ounces of water to your daily intake. The easiest way to do this is to keep a glass or container of water at your bedside, that way as soon as you wake up and start your day, you can begin drinking water. Keep Track By Your Container: One thing that has proven to help people consumer enough water daily is to buy a special container for their water, like this one or this one, and set a goal of how many times they will fill an finish the container. For example, if you buy a 16 oz container and need to drink 80 ounces of water a day, your goal would be to drink 5 of those daily. Need to drink more water? Try a larger container. Infuse Your Water With Flavor: Water doesn't have to be boring and infusing your water with fruit, herbs, and other flavors can make it much easier to reach your daily goal. Try adding cucumber, strawberries, lemons, limes, and fresh herbs to create flavorful water. This fruit infusion water pitcher is a great way to always have great tasting water on hand. Bubbles: Consider carbonated and sparkling water in addition to regular water. Many people find that adding sparkling water and 0 calorie flavored water makes drinking water throughout the day more fun. Find yourself drinking lots of expensive sparkling water? Consider buying a sodastream and make your own delicious sparkling beverages at home.
I've heard you only need to drink when you're thirsty. And 8 ounces shouldn't be the amount for everyone. I'll drink when I'm thirsty. But I sometimes just put it off and go through until I'm eating a meal and drink something with it. Or I'll drink something else than water. But then again, I have an approx. 750mL water bottle and I drink that straight a few times a day so maybe I'm closer than I think.
Why worry? Your body tells you these things. You lose moisture from your mouth first for a reason, to tell you to drink. Its crazy trying to micromanage every little function in life. You'll drive yourself nuts
At least a quart on non-workout days, probably a quart and a half on workout days. I do drink other liquids throughout the day, lots of coffee which doesn't count because it's a diuretic, normally drink juice too.
I think it really depends on your weight and how much you're sweating. Like an overweight person running laps on a track in July would need to drink a lot more water than a 100 pound sedentary person who never sweats. Personally I drink about two glasses of water with every meal.
A good way to determine how much water to drink a day is to convert your wait to kilogrammes and put a comma infront of the last digit. For example I weigh 58 kgs so I drink 5,8 glasses of water a day.
