Word is that some of you people are nerds.
I know, I know. You’re shocked — shocked! — to find gambling going on at Rick’s. You and me both.
Anyway, here’s a story, and question, that IMAO Regular “Jimmy” related to us once:
One of my sisters is morbidly overweight. When she was visiting me one day, she asked that I get her a glass of water. I asked her if she wanted cold, filtered water from the fridge, or, room temperature filtered water. She said, “Cold. It helps me burn calories and lose weight.”
I chided her about that and asked if she’d ever done the math to know how many Calories an 8 oz. glass of 38°F water would force her body to burn. “No.” (This sister was valedictorian of her high school class and had a year of Chemistry so she should be able to do the math – at least how to approach getting an answer.)
So, I told her I had done the math long ago and gave her the answer and explained it.
IMAO nerds: How many calories will you burn by consuming an 8 oz glass of 38°F water? Provide your best answer in the comments.

Like Jimmy said, answer in the comments. Show your work, or everyone will know you simply Googled it.

If it’s Detroit water, probably quite a few, takes a lot to melt the lead.
It takes one calorie to raise one gram of water one degree.
An 8 ounce glass of water is two hundred and something grams, let’s go with 225 because it is close enough (I’m trying ti not to use google and doing math in my head while sober)
To bring 38 degree water up to body temperature of 98 degrees would be a 60 degree climb.
60 times 225 is thirteen thousand calories…… which is the point where I realized I am using calories as a measure of heat and not the “nutritional” kind of calorie” so I will just slowly back away from the keyboard and hope no one notices and the few that do just kinda go with it and we all have a laugh while standing at the bar contemplating how the ice is cooling down our whisky.
Time to start drinking more room temprature liquor….

Drinking water? What kind of friggin, frickin’ frackin’ IMAO poster do you take me for? Pass the Tequlia!
And the hookers!
Oh, and a Tuna fish sammich would not be out of order.
I assume this question is talking about thermodynamics and the amount of heat energy the body has to use to heat up the water.
So, a “calorie” is defined as “the amount of energy necessary to raise 1 gram of water 1 degree Celsius.”
First, you have to convert the temperatures from C to F. 38F is about 3C. 98.6F is about 37C. So, (rounding) we’ll need to raise the temp about 34 degrees.
Now, we will also need to get the ounces to grams. Standard conversion factor is 1 oz = 29.57 g. S, 8 ounces of water is about 237 grams. So, how many calories will it take to heat up 8 ounces of water from 38 to body temp. 237 x 34 = 8043. Actually, if we don’t round, then it’s about 7964.
So, why doesn’t everyone just drink lots of cold water and be skinny? That’s a LOT of calories.If you drink as much water as they recommend (64 ounces), you will have to burn up over 60,000 calories.
First of all, it’s really the difference between that and 8 ounces of water at body temp. Not a lot of folks drinking body temp water. Hotter? Yes. Colder? Alright. Body temp? Gross.
But the biggest thing is that a “food calorie” and a “calorie” are not the same. Actually, when we talk about calories in food, it’s 1000 calories (kilocalories). So, it actually burns a whopping 8 “food calories.”
High Praise!
And Bacon!~~~
Anything for bacon!
NERD!
How many calories does that bacon offset from the cold water?
All hail Chuck Hale
Same answer I got.
Does it make any difference, scientifically ‘n stuff, if I substitute 64 oz of cold beer for 64 oz of cold water?
Told you there were a lot of NERDS here, Basil!

I’d call in a physiologist here.
If 38-degree(F) water is going in, and we assume 98.6-degree water is coming out, the water has heated 60.6 degrees. I don’t know if this assumption is even valid or not. Let’s pretend it is. Let’s say the water remains in the body long enough to heat up to body temperature, and, assuming it does:
At 28.34952 grams per ounce, 8 ounces would equal 226.79616 grams.
To heat each one of those 226.79616 grams by one degree (the definition of a calorie) requires 226.7966 calories.
Do that 60.6 times, and you’ll use 13,743.87396 calories.
But the physiologist will have to answer where those calories actually are generated.
Chemical reactions (with substances and acids in the stomach) interacting with the water may produce some of the heat.
Convection may even provide some heating of the water, but I don’t know how. I’d ask the physiologist about that.
Conduction of heat from nearby organ walls or stomach liquids must produce the rest of the heating. (Assuming that radioactivity is negligible in our example.) This is where you’d have to get the physiologist to tell us *how* heat by organs or liquids is replenished: is it by the breakdown of substances in the stomach, or from frictional heat generated by muscular movements, or from actual burning of any fat outside the stomach?
I’m worried that the next question is going to ask about the calorie difference between drinking a glass of cold water with ice in it versus one without ice in it!
Yup, scratch all my math!
A calorie is defined as “the approximate amount of energy needed to raise the temperature of one gram of water by one degree Celsius.”
The type of “units” oversight which explains a lot in my science grades. (And the loss of at least one Mars lander.)
There will be a quiz.
For me, this was Distrait Line of the Day.
Or a psychologist.with a minor in physics or chemistry.
I told her that one correct answer is that Conservatives will burn a heck-of-a-lot more Calories after drinking the water than Liberals. As a Liberal, she didn’t like that.
For Liberals does drinking the Kool-Aid count?
So, it actually burns a whopping 8 “food calories.”
Well, if we follow Sister’s advice and drink 8 cold glasses of water each day, that’s a difference of 64 food calories. 64 food calories times 365 days per year equals 23,360. It takes 3,500 food calories to burn off a pound of fat (according to the infallible internet). 23,360 divided by 3,500 is 6.67 pounds. So, if I ignore Sister’s advice and drink 8 glasses of tepid water every day for the next year, I will be 6.67 pounds fatter at the end of that year than I would be if I did everything exactly the same, but drank icy water instead. (Not exactly, of course, because room temperature water is rarely 98.6 degrees, except in my house in the summer.) Since I prefer icy water to tepid water anyway, I will continue drinking it with the newly gained understanding that I would be even fatter than I am now if I didn’t love chewing on ice so much.
It is good that she is trying to burn 8 calories. She would burn 8+ some similar insignificant amount if she got out of the chair herself. The real problem is she probably assumes it is a lot more than 8 AND that because she is drinking cold water she can reward herself with a treat. The treat would be more than the 8 calories; even a carrot is more than 8 calories. Thus, she is behind. I find it interesting when people go for a 20 minute, slow walk, maybe burning 100 calories and then feel they can reward themselves for being good with a piece of chocolate cake having 300 calories. Then they wonder why they don’t lose weight.
In the interest of burning calories, wouldn’t it be more productive to tell her to get it herself?
Okay, Burt wins.
Yes, but I was trying to be nice to the old Liberal lady. Besides, getting up out of an easy chair wasn’t her forte.
As she was described by you as “morbidly overweight” I gathered that she was not the most active person in town.
You’re all forgetting the energy needed to eliminate that 8 oz. of water from your system, including the force multiplier a balky prostate can impose….
I’m surprised no one has attacked this problem with British units.
May have been easier because there is only one conversion at the end instead of 2:
BTU is raising 1 pound of water 1 degree F. 8 oz is 1/2 of a pound.
98.6-38 = 60.6
60.6 x 0.5 = 30.3 BTU.
1 BTU = 0.252164 KCal
30.3 BTU = 7.6405692 KCal.
I find it kind of interesting that 1oz of cold water is about 1 Calorie of heat (I was taught to use capital-C for Calorie = kCal).
There’s also another school of thought that your body responds to the cold input by burning more calories (than the net loss itself) to catch up . The “drink cold liquids when you’re cold and hot liquids when you’re hot” wives tale (to make you sweat more?). But I like drinking 16 oz. of 38F water when I’m both dehydrated and overheating due to hard work in the summer sun. Makes me stop sweating in about a minute or two.
And Yes, KCal is the answer . When people talk dietary calories, they are actually talking about KCal. so that glass of water will burn about 7 Dietary Calories per the correct calculations above. . Or so. Since we know that no process for heating anything is 100% efficient, and since the body is largely heating this via blood flow.. and since there may be overshots as stated above, I am sure the body actually has to use more stored chemical energy to heat the water than the minimum 7 Kcal. . But even assuming 30% efficiency ( its probably way better than that ) you are still only going to burn 21 Calories per glass of water. But compared to the 1 (Kilo) calorie you will get from a diet soda, plus the mess the artificial sweeteners make of your endocrine system( we have carbs! no wait.. we don’t!) having that glass of water is a hell of a lot better for helping you loose weight than anything else you might decide to drink. .
One of my sisters is morbidly overweight. When she was visiting me one day, she asked that I get her a glass of water.
The correct answer would have been….get it yourself and you’ll burn more calories than drinking it.
But that probably would have been some sort of hate crime.
…and Rodney was half right.
If Hillary drank that same glass of water, she would poop ice cubes, the cold hearted so-and-so…
One last side note to this story (at least from me):
If I drink a 16 oz. of 38°F water (1 lb.), that’s -60 BTU’s of cooling on my body. If I have 3 gallons of blood in me at roughly the same density as water (8 lbs./gal) then -60 BTU’s / 24 lbs. = -2.5 BTU’s / lb. of blood. A BTU will raise/lower 1 lb. of water ±1°F. So, if the affect of drinking the cold water were all transferred to my blood (via my stomach lining), it’s temperature would drop 2.5°F which could explain why I seemingly cool down quickly when I drink it. If I weighed 180 lbs, the affect is only 0.67°F drop in temp, so our bodies must be fooled somehow into thinking they’re not hot anymore and can stop sweating. (At this point, I’m with Oppo, call in the physiologist for an explanation!) (Note: I actually took my temperature once after overheating in the sun. It was 102°F)
Okay, I’m a nerd.
Popcicle Scotch. The cause of, and answer to all lifes problems.
I learned long ago to substitute cold water with cold beer. It hasn’t helped my weight much but I’m always happy at the end of the day.
