If you’ve dabbled into the fitness world, you might have heard the staple that you should drink a gallon (yes, gallon) of water per day. You might also see your favorite Fit-stagrammers carrying a milk jug full of water in their posts, and hear jokes about constantly using the bathroom as a result. But is a gallon too much? Where did this rule of thumb come from?
Now back in my day (wow, am I old??) the rule was you should drink around 8 glasses of water daily, but that rule was always a bit tough to actually adhere to. 8 big cups? Small cups? Too many cups! The fact of the matter is, the 8 Cup rule is not really backed by hard evidence.
According to the Institute of Medicine, the average adult male should drink approximately 13 cups (3 liters) per day, and the average woman approximately 9 cups (2.2 liters) a day.
Each body is different, so it would make sense that not everyone would be required to drink the same amount of water. A 6’5″ man would need more water than a 5’0″ woman.
Plain and simple, a gallon of water a day is a lot, and certainly more than the above recommended intake, but if you space it out throughout the day, it won’t hurt you. But you WILL have to go to the bathroom a LOT, which is good! Flush out all those toxins.
Water intoxication does exist, and it is dangerous. So if you decide you want to drink a gallon a day, please make sure you space it out and not guzzle it all at once.
