Review: Gallon Of Water Per Day For A Month!


Well, this makes me thirsty…

A month ago, I came across an article describing a woman who drank a gallon of water per day. She lost weight, decrease her waistline by an inch and experienced remarkable improvements to her skin. The bags under her eyes disappeared and she looked ten years younger.

I was skeptical, but sometimes you need to try things for yourself.

And so I did.

As promised, I’ve been drinking a gallon of water per day for the past month. As many of you reminded me, too much water can be dangerous. But with Mayo Clinic recommendations of 13 cups of water for men (with more if you exercise) and nine for women, the 16 cups in a gallon of water should fall within the margin of safety. Of course, it’s always wise to check with your doctor.

Each morning, I filled up a gallon jug of water. Throughout the day, I used the jug to monitor my progress. Of course, eating in a restaurant made the science less exact – so, in some instances, I had to use my judgement and estimate. Nonetheless, I completed the challenge for the full month.

So, what’s the verdict?

First, I was surprised how easy it is to drink a gallon of water per day. It sounds and looks like a lot, but I’m pretty sure I drink almost a gallon on a daily basis even without the challenge. Truthfully, it probably only amounted to an extra few cups. And the only change that I noticed was having to get up once or twice during the night to pee.

All in all, I don’t look or feel any different.

Perhaps the woman in the article was severely dehydrated when she started the challenge. If that’s the case, it’s likely that the challenge did provide some pretty substantial benefits. But if you’re already fairly well hydrated like myself, you might not notice any changes.

Having said all of that, I really do like the idea of having a gallon jug of water to better track my hydration. Sometimes, sipping water isn’t a priority and the jug is a good reminder to drink up. For that reason, I may continue with the challenge when I’m home or when it makes sense.

  1. I did the gallon a day challenge. I didn’t feel any different after doing it. I will say my skin has been a little clearer but over all I didn’t see a difference

  2. Marshall S. says:

    I did the gallon of water a day challenge & am still doing it, however, except for having to pee a little more often, I really saw no difference or changes. Take note however that I was already drinking 10-13 glasses a day prior to the challenge.

  3. I think the challenge is more focused on those who currently drink maybe 3 – 5 cups of water a day (or even no water a day), instead drinking sugary drinks, coffee, soda, tea, etc. I’m sure those people will notice significant benefits from finally being hydrated for once in their life. If you’re already consuming 10-15 cups of water a day, the added hydration will probably just make you pee.

  4. I did the challenge with you as well. I did actually lose a few pounds and I noticed a significant difference in back pain and joint pain. I have always had awesome skin. I look really young for my age as well. I’ll probably keep doing it because I have had 3 back surgeries and any significant reduction in my pain level makes it worth it for me.

  5. In the military, they tie a cord to their belts and tie a knot each time they have a glass of water, 8 knots at 8 oz. each = 1 gallon. Might be better than dragging a gallon around with you!

    • But 8 x 8oz. is only two litres … like half a gallon

      • liz gunning says:

        ^^^OMG! 8oz X 8oz
        = 64oz=1 GALLON! i cannot believe you said that! hhhhaaaaa! back to 4th grade math with you! i actually did have a client shout that same thing out in class and the entire gang stopped dead and turned around in shock!

        • 8 x 8oz does equal 64 oz, so you are correct on that math. HOWEVER, a gallon is 128oz, which means your 64oz is only 1/2 gallon or 2 quarts

    • Umm… that’s not a gallon.

      • 1 U.S. Gallon is equivalent to 128 U.S. ounces. If you’re going to attempt to diss somebody on being “wrong” then a) actually make sure they’re wrong and b) make sure your information is correct.

    Davey, you are so sexy and handsome. You do not need to haft to feel to look younger. I think you are super stud hot! Every photo you post is eye candy to me anyway.

  7. I dink alotta water per day.Got a non stop erection!

  8. orkunzafer says:

    Well I try to drink 1,5 Lt bottle of water per a day. My skin is so greasy so when I dont drink enough water or when I eat fatty meals I feel very uncomfortable with my skin. I want to say I feel very well when I drink 1,5 Lt of water during the day. It makes my skin elastic, less oily and fresh. So I do believe drinking water works in everyway. Even when u pee because when u pee so much it works your kidneys (that is important for your health) and u put off your toxics from your body ๐Ÿ˜€

  9. Kim A. Marston Jr. says:

    I was hospitalized last year after a motor vehicle accident and I suffered acute renal (kidney) failure. I was also dehydrated. The doctor suggested drinking a gallon of water a day. I started doing so and my physical appearance didn’t improve, but both my high blood pressure and cholesterol improved along with my kidney functions. I’d say it’s definitely a plus when thinking holistically and not just on outward appearance. Hope this helps! Love to All ๐Ÿ˜‰

  10. Unless you were in an accident or have a condition, you’ll drink when you’re thirsty, and you’ll live till a ripe old age whether you want to or not ๐Ÿ˜‰

    • Except that our brain turns on our thirst mechanism when we are already in a slightly exaggerated state of dehydration. So waiting until you’re thirsty to drink isn’t really a good thing either.
      But reading about all this water sure is making ME thirsty right now…

  11. I tried the challenge also but didn’t last the full month. I bought a gallon water jug that benefited some charity. Damn a gallon of water is heavy to lug around. Anyways, I’m healthy, fit and work in the fitness industry but sometimes I know I don’t drink enough water. The first few days all I noticed was a few more trips to the restroom. By the 2nd to 3rd week I started to get a little bit of acne. I figured my body was pushing out toxins with all the water. I never did finish the challenge as lugging the jug around was a pain. But I’m making myself drink more water. So some good has come of the challenge.

  12. I have found that drinking a sufficient amount of H2O (depending on sex, metabolic rate, climate one lives in…) is all very simple to figure out. I believe complimentary additions produce a significant change – if one is well and regularly hydrated. In my case, I happen to use (in its purest, gel form) Aloe Vera daily. I use it externally as a coolant and “topical medicine” every day/night; and I also prepare an Aloe “milkshake” twice a week using Aloe Vera, Almond Milk, Wheat Germ and a dab of honey. I have NEVER felt this clean, clear and healthy in my life. Everything in moderation of course. But look to nature as much as you can. Why buy a $30 face cream whose first ingredient is Aloe Vera – if you have the ability to cultivate or purchase it yourself? It might not be that simple for everyone, I understand. But the purest form of any ‘medicinal’ plant is always the route to go….even for those plants, roots and leaves that may need boiling, steaming, blanching,,,,etc. I am no “BODY BUILDING PRO” or anything of the sort. I am an average woman, living day to day, facing the same circumstances and stresses as the rest of the world. The difference? I fell a heck of a lot calmer in general and find that problem solving comes much easier because the brain is able to function at a great capacity. God bless you all! Stay hydrated, in whatever way you can…
