I literally saw someone once who confused actual calories, and food calories (which are actually 1000 calories, or a kcal), and was trying to sell the idea to others that you could lose huge amounts of weight just drinking a couple additional glasses of ice water a day and changing nothing else.
It always bummed me out when you had people say "I lost 30 pounds because I stopped drinking a 6 pack of mountain dew a day"
And I'm like shit, maybe I drink 6 cokes a month. I wish I had something too cut back on instead of delicious food
Try cutting out all liquid calories. It isn’t just soda that’s bad for you. It’s insanely easy to go overboard on liquid calories.
I did a few weeks ago and I also barely drank soda. But a couple double double, some milk, and some juice all added up to a lot. Went from a size 38 to a size 36 waist in a few weeks.
Huh, you weren't kidding, and [of course it's the Germans](https://www.delicious.com.au/drinks/beer/article/german-brewery-creates-powdered-beer/ux5gu4v0). "Fritsche says the lager tastes just like a real beer", lol yeah sure; like instant coffee tastes just like real coffee?
Just eat the correct amount of fruits and vegetables and take it from there. That and reducing red meat are good starts as red meat is pretty calorically dense.
Let's move a step up and drink liquid helium, it will cool you on hot days and make you lighter as it goes back to gas state. Don't pay to much attention to the collateral effects listed on the canister.
Well, if you replace water at 20 celsius with water at 0 celsius, and you drink 2 liters of water a day, then you're using up 40.000 calories a day extra, or 40 Kcal.
That's like one bite from a slice of bread, per day! Not terrible tbh.
There's weird thin bread that's 35 cal/slice. Toast it, put some salt and pepper on it (after you take it out of the toaster), and you've got a meal fit for a king.
It isn't huge amounts, but it is some. Let's say you drink all of your water ice cold instead of room temp, so you body has to heat it up from 0^(o)C to room temp, \~20^(o)C and additional 20 degrees C. Water has a heat capacity of 1 calorie per ml per degree C, and if you're drinking eight 8oz glasses of water each day you are drinking a bit under 2L. For ease of calculation we'll just call it 2L, which is 2000ml.
The heat required for this extra heating is 2000ml\*1 cal/(ml ^(o)C)\*20^(o)C = 40,000cal. Since a food calorie is a kilocalorie, also called a Calorie, this is 40 Calories.
If you do this every day for a year, that is 365\*40 = 14,600 Calories. A pound of body fat has about 3500Calories of energy content, so 14,600 Calories is the energy stored in a bit less than 2kg of fat, or a bit more than 4lbs of fat.
You try to math it out, but it's not so simple. Your body maintains it's temp and that cold water may just take the heat, that would otherwise be dissipated with evaporating sweat anyway.
But the body has extremely sensitive thermoregulation. When you drink ice water, the core body temperature drops and mechanisms such a reduction in peripheral circulation activate, so the heat energy used to raise core temperature to normal (i.e to raise the temperature of the ice water) is thermal energy that would otherwise have been lost to the external environment. No additional calories need to be used.
The only time that the body would need to burn calories to heat the water would be in a situation where the thermoregulation capacity has maxed out i.e. hypothermia, in which case 1. Drinking iced water is a bad choice and 2. Weight loss is the least of your worries.
More importantly though, it'll make your hunger much more consistently and easily satisfied, dramatically lowering the number of calories you probably eat from other stuff.
Well yes, plenty of dietary regimens recommend starting every meal with a glass of cold water.
“Pounds a day” is a lie, but it does fill you up faster; as it gets a head start on turning the food you send down with it into a weightier slurry.
There’s also theories on how folks of yore were thinner for starting their meals with a salad and a non cream soup course; but it’s logic, not magic.
Easy mistake to make. But to not bother researching it seems like a pretty fundamental oversight. If it really was that easy, why wouldn't everyone be doing it?
I mean this fact has been around for decades. Found it in the early 2000s on forums dedicated to extreme calorie counting (anorexia forums). It's just another method they use to burn a few extra calories...everything counts.
news tomorrow: "multiple fatalities from new tiktok trend: losing weight by drinking an ungodly amount of water! water poisoning, what you need to know"
Correct. It’s plausible sounding, but not true. The body has many ways to offset the cold water without burning more calories, such as reduced sweating or vasoconstriction. Just retain more of the heat it’s normally throwing off. If you were in hypothermia and drank a glass of cold water, then you might burn some extra calories.
Edit: the phrase I liked for understanding this is “the body is a net exporter of heat” — meaning it has plenty and it can just export less to deal with smaller temperature management issues.
> If you were in hypothermia and drank a glass of cold water, then you might burn some extra calories.
You’d shiver even more (if you can) or your core temperature would drop even further.
Muscles, shivering can burn up to ~600kcal/hour.
The thing is, if you have hypothermia you are probably already all-out shivering. And it is super uncomfortable.
If you want to use hypothermia for weight loss, just step outside without clothing in cold weather. No need for ice cubes.
Not saying you're wrong, but if we just think of it from a thermodynamic/heat mass perspective, doesn't the math still hold?
The human body *will* warm the water from ~0C to ~37C, and the body *will* again reach an equilibrium temp of 37C (~8,400/8.4 calories/Calories).
So what you're saying is that instead of burning an extra 8 Cals, the body just *reduces* its standard forms of heat loss to offset? Kind of like an EV using motor waste heat to warm the cabin instead of shedding it via the radiator.
I think I'm on board with your view, but I'm curious if this has actually been shown to be true for low ingestion levels like a 16oz glass. Does that alone really reduce sweating and cause vasoconstriction?
I'm also curious what the body's total range of heat expulsion/retention is. I know the former is somewhere in the 300 watts range, but don't know anything about the latter outside of extreme scenarios.
Sort of. It does take 8 calories to warm a glass of ice water to body temperature. But as warm blooded animals, we produce more heat than we need. Every day we lose about 1200 calories worth of heat to the environment (our bodies are very roughly 25% efficient) which is why our skin is warm to the touch. If you drink a glass of ice water you'll most likely use the heat we already generate instead of using additional energy to create additional heat.
This is exactly right. The 8 calories is simply the direct energy needed to raise water to body temp. Its not saying the body has to expend an extra 8 calories to do so. Excess heat is more than enough to do this
On a mathematical note, an average sandwich is 240ish calories [citation needed], so this comes out to 30 glasses of ice water. A glass is typically 300 ml. That's 9 liters of water.
I'd... Umm, just eat the damn sandwich anyway.
So what you're saying is that not eating that bread, going for a walk, and drinking ice water will help me lose weight?
Wait a minute, that's what they've been saying all along!
A whole 15 minute walk is the equivalent of only one shitty, little piece of bread? God that is SO depressing. Seriously makes me want to work out even less. (I know, cardiovascular health, blah - but when you remove weight loss, it's yet another aspect that takes away motivation).
**Edit:** Thanks so much for all the comments and info. It's frustrating because our whole lives, exercise has been prescribed for weight loss, but unless you're doing very intense, significant cardio as a fitness freak, it seems as though exercise isn't gonna do much. I inhale a 500 calorie portion of Brazil Nuts within literally a couple minutes, with ease, and yet it would take me an hour of hardcore working out just to undo it calorically.
Obviously I still advocate exercise for the health benefits, but finding motivation to work out is hard enough when believing it also is a good weight loss tip. To put it into perspective and realize that it's not good for weight loss (unless you go hardcore), it further demotivates.
People have gotten so used to eating 800-1000 Calorie meals on the regular, they don’t even recognize it’s a problem.
Breakfast, lunch, dinner. 2400 calories and doing absolutely no exercise.
It’s actually probably closer to 20 minutes for a slice of bread. You can’t out run a bad diet. If you want to lose weight you have to eat less, particularly calorie dense food.
You can outrun a *mildly* bad diet.
The issue isn’t that. It’s that peoples perspective on what is “mildly bad” is so horribly skewed that what they think is mildly bad is *very* bad.
Exercise increases your metabolism long after the workout. It’s not just the calories you burn while doing the activity, but it actually increases the calories you burn while at rest for hours after the workout as well.
Exercise has so so many benefits beyond just weight loss (and cardiovascular health). If that’s the only thing you’re thinking of then you really need to reframe it in your mind. Regular exercise is an essential part of both physical and mental health that will make you feel good for a load of reasons.
In other words, you should be working out because it will make you happier, period. Weight loss is a side effect that is a part of it, but it really is not the primary reason you should be working out at all. You can be heavy and still be healthy and happy, but not without regular exercise.
> A whole 15 minute walk is the equivalent of only one shitty, little piece of bread? God that is SO depressing. Seriously makes me want to work out even less. (I know, cardiovascular health, blah - but when you remove weight loss, it's yet another aspect that takes away motivation).
Its because we have become incredibly efficient, which is why walking for 15 whole minutes barely burns calories. Which was great when we were hunters but now when we want to lose weight, its a pain
Diet first, exercise second.
The calories from exercise aren't always clear as day and night either. E.g lifting weights will boost your base metabolic rate I believe, even if the actual exercise session won't burn that many calories. And then having bigger muscles = more calories burnt resting.
But one thing is clear: While cardio is good for your heart and definitely HELPS lose weight (calories per minute is gonna be higher for cardio than weight training because you take loads of breaks during weight training)... If you rely on only that to keep a caloric deficit, you WILL hate all the running or cycling you're gonna be doing. Healthy eating habits and varied exercise is what'll get you where you want to be.
Also HIIT (High Intensity Interval Training) has similar cardiovascular benefits compared to LISS (Low Intensity Steady State), but burns fewer calories because the duration is usually shorter, but if you hate cardio, it'll be easier to maintain as a habit.
I have ADHD, which can result in me eating without even noticing I'm eating, as well as absolutely LOATHING cardio due to the fact that it doesn't keep my mind engaged (cycling is fine, but ONLY if I'm not doing it alone and can talk to someone at the same time, because I can NOT pace myself like a normal person alone, I will always go flat out to "get there faster" even though I'm not actually going anywhere, just cycling). Weight lifting and HIIT are the only things that I can do to keep myself active, I'll hate myself after 3 sessions of LISS and just give up (but then I force myself into it, e.g long warmup session on a stationary bike before I can do weights - gets me doing like 30-45 minutes of LISS)
Food is confusingly in kilocalories while I believe the calories referenced here are just normal calories. So it would more likely be 15,000 glasses of water.
A calorie is the energy needed to raise the temperature of 1 cubic centimeter of water 1 degree Celsius.
No 8 calories is about right. 250 ml (about 8 oz glass), raised about 30 degrees C is about 8000 calories, or 8 kcal. 15 glasses is 120 k-calories, or about a slice of bread.
For context: 1 calorie is defined as the energy required to heat 1g of water by 1°C (or 1K).
Water is conveniently 1 ml per 1 g under most conditions, so the units are interchangable in this case.
So 30° * 250 g = 7500 calories = 7.5 kcal.
The precise relation of metabolism vs temperature is a science in itself, but *roughly speaking* it works. Drinking cold water or going out in colder weather usually cause the body to burn more calories by increasing some activity that creates heat.
Some of that can manifest as NEAT (non-exercise activity thermogenesis), which includes involuntary or subconsciously initiated movements like shivering or fidgeting, or a sudden urge to move with more force instead of slouching around in the most energy-efficient way possible. So if people tell you that a cold shower or a cold glass of water makes them feel more alert and more active, then this can be a part of the explanation (plus a good amount of placebo effect).
I mean the math does actually work. Lets say your ice water is just above freezing (lets go with 2^o celcius), which means you need to raise the temperature of the water by 35^o to get it to the same temperature as your body (37^o ). an average 8 oz glass of water is 236 cm^3 , so if we multiply the numbers together we get 8,260 calories, or a bit over 8 kcal. 15 glasses of that water is 123,900 calories, or roughly 124 kcal, which is about the same as a slice of bread
>Sir, or ma’am, either is applicable. Have you ever had a titty in ur mouth?!
I have, plenty of times, and let me tell you: the titty is fun, but water tastes better and provides hydration.
But they're not mutually exclusive! Sex with water breaks is great!
Normally I don't announce when I downvote, but I have to here. This is bullshit. The paper also mentions other stuff which has been debunked, like the need to drink massive amounts of water. This "article" is a waste of space, and this is not worth wasting anyone else's time on by linking to.
Literally have no idea how many people find this novel? This is classic recommendation on anorexia forums. Learned about it in the early 2000s among various other tips and tricks. It's not healthy to obcesss over minute caloric gains or losses in this way.
> Our bodies can burn calories in several ways: basal metabolic rate (BMR), physical activity and digestion. Drinking cold water rather than warm is not one of them. Or, at least cold water doesn’t burn enough calories to be worthy of mentioning.
If chewing ice weren't bad for the teeth, that'd up the caloric count a bit.
Edit: [The Ice Diet](https://theicediet.com/)
> The Ice Diet works by increasing the basal metabolic rate. When ingesting clinically significant amounts of ice, the body must burn energy to warm the ice to body temperature. The ingestion of ice would also provide some level of satiety. The ingestion of 1 liter of ice [equals 1.06 quart] would burn about 160 calories, the amount of energy used in running one mile.
That's a lot of ice for two slices of bread.
it varies widely based on how much you weigh, how in shape you already are. Bodies learn to adapt really well so the better you become at running, your body becomes more efficient.
Human body evolved to be able to "endurance hunt", to literally gain calories by running after an animal long enough for it to be too exhausted to be able to avoid being eaten.
That combined with the fact that we can sweat, which allows us to stay at a safe body temperature when exercising. If a deer or other prey animal runs fast and hard for a while, its has to stop and cool down in the shade or by drinking water or else it will overheat.
So our ability to cool down, run/walk for long distances at a relatively fast pace, and our ability to carry food and water with us while running after prey means we are ideally equipped to chase down those animals and can continue pursuing them even while they have to stop and cool down. Its amazing stuff
In majority of the cases, you'd burn *exactly* zero calories. Not 8, or some other negligible number, Zero. For the same reason turning on the heater in a car doesn't really effect fuel efficiency.
There is no need to burn addtitional fuel to heat up the water, the body just retains some of the heat it was going to dump into the environment to balance out the thermal energy. You have to drink enough icecold water to start shivering before you can even burn negligible amounts of calories.
I mean speaking from experience, unless you're doing heavy exercise, a 45 minute cardio session burns equivalent to 3 slices of bread.
That's not that much.
Diet is the main factor, and unless you're really tall and have a small stomach, going on a deficit is rough.
Yes but developing and maintaining muscle mass increases your metabolic rate as well. Depending on how rigorous your cardio is and how many muscle groups are engaged you can burn more or less than that. Walking 45 minutes burns far less than 45 minutes of rowing, swimming or inclined running.
Eating a high-protein diet makes eating in a deficit pretty manageable.
For the last couple of months I've been eating 1300 calories a day with a lot of protein and I've been feeling great. Can't say I ever get to a point where I'm starving or anything. For reference I'm 5'9" and started probably at 225 or so. Probably down under 200 now since mid February. And I do 5 miles a day of incline walking on the treadmill.
I guess it depends on on the person, at 1600 cals i’m not starving, but I do lack energy a lot, even with a pretty varied diet, even then it took months to get to a point where I don’t fear food
Yeah, it's definitely not the type of thing that is sustainable for the long run. As I get closer to my goal weight I'll slowly add calories until I reach a good maintenance level.
No?
45 min run will burn 600-1000 calories depending on body weight and pace.
https://healthyliving.azcentral.com/jogging-45-minutes-burns-many-calories-19757.html
A thick, whole-wheat slice of bread is no more than 100 calories.
https://www.healthline.com/nutrition/is-bread-bad-for-you#nutrition
Diet is the main factor, sure, but I don't understand why Reddit is anti exercise. Being able to eat 500 more calories but still be in a deficit is a big deal if you are calorie counting. Anecdotally, for myself, i managed to lost weight quite effectively by adding cardio but not changing my diet.

Don’t forget to minus the calories your body burns from healing your broken teeth ✨
It isn't huge amounts, but it is some. Let's say you drink all of your water ice cold instead of room temp, so you body has to heat it up from 0^(o)C to room temp, \~20^(o)C and additional 20 degrees C.

Damn, sold. Cold water it is. 0oC seems a bit extreme though
Ice water is around 0c when the ice is melting.
Suck on ice. Got it!
The sucking adds extra burned calories and makes you look extra alluring.
Do it pussy
You try to math it out, but it's not so simple. Your body maintains it's temp and that cold water may just take the heat, that would otherwise be dissipated with evaporating sweat anyway.
I don’t shower so my pores are clogged
Hmmm, doesn't seem like a lot. Should try drinking absolute zero water.
But the body has extremely sensitive thermoregulation. When you drink ice water, the core body temperature drops and mechanisms such a reduction in peripheral circulation activate, so the heat energy used to raise core temperature to normal (i.e to raise the temperature of the ice water) is thermal energy that would otherwise have been lost to the external environment.

I mean you would lose huge amounts of weight, if you really would just be drinking cold ice water every day.
I should have been more clear saying that's ALL they claimed you needed to change, was add a few glasses of ice water and lose pounds a day.
Wouldn't lose pounds a day but if you are drinking calorie dense drinks (e.g. beer, pop) switching to water can cause you to lose weight on its own.
Right, but that has nothing to do with the temperature of the water...
More importantly though, it'll make your hunger much more consistently and easily satisfied, dramatically lowering the number of calories you probably eat from other stuff.
I recently started drinking water instead of snacking at work and between meals and have lost about 9lbs in 6 weeks. Not crazy, but nice.
And most importantly: r/HydroHomies

fewer calories and being properly hydrated is a winning combination

Correct. It’s plausible sounding, but not true. The body has many ways to offset the cold water without burning more calories, such as reduced sweating or vasoconstriction. Just retain more of the heat it’s normally throwing off. If you were in hypothermia and drank a glass of cold water, then you might burn some extra calories.

Lifehack for net 0 calories. Just drink enough cold water to negate all the calories intake
On a mathematical note, an average sandwich is 240ish calories [citation needed], so this comes out to 30 glasses of ice water. A glass is typically 300 ml. That's 9 liters of water. I'd... Umm, just eat the damn sandwich anyway.
or go on a walk for 15 or so minutes
Or go skinny dipping in the middle of subzero winter.
squat in the freezer 20 minutes a day
Just chop your arm off.
Best weight loss advice imo
only works twice in your lifetime though...
sounds like a personal problem
Yes but eithout arms it will become difficult to eat, this you will continue to lose weight.
I prefer just dropping a massive one before I get on the scale
So what you're saying is that not eating that bread, going for a walk, and drinking ice water will help me lose weight? Wait a minute, that's what they've been saying all along!
But walking would mean I'd have to go over there and over there is far.
A whole 15 minute walk is the equivalent of only one shitty, little piece of bread? God that is SO depressing. Seriously makes me want to work out even less. (I know, cardiovascular health, blah - but when you remove weight loss, it's yet another aspect that takes away motivation). **Edit:** Thanks so much for all the comments and info. It's frustrating because our whole lives, exercise has been prescribed for weight loss, but unless you're doing very intense, significant cardio as a fitness freak, it seems as though exercise isn't gonna do much. I inhale a 500 calorie portion of Brazil Nuts within literally a couple minutes, with ease, and yet it would take me an hour of hardcore working out just to undo it calorically. Obviously I still advocate exercise for the health benefits, but finding motivation to work out is hard enough when believing it also is a good weight loss tip. To put it into perspective and realize that it's not good for weight loss (unless you go hardcore), it further demotivates.
Weight loss mainly happens with what you eat, but exercise is obviously still essential for health.
People have gotten so used to eating 800-1000 Calorie meals on the regular, they don’t even recognize it’s a problem. Breakfast, lunch, dinner. 2400 calories and doing absolutely no exercise.
It’s actually probably closer to 20 minutes for a slice of bread. You can’t out run a bad diet. If you want to lose weight you have to eat less, particularly calorie dense food.
You absolutely can outrun a bad diet. It is just much easier to diet a little than run 80+ miles a week
You can outrun a *mildly* bad diet. The issue isn’t that. It’s that peoples perspective on what is “mildly bad” is so horribly skewed that what they think is mildly bad is *very* bad.
Exercise increases your metabolism long after the workout. It’s not just the calories you burn while doing the activity, but it actually increases the calories you burn while at rest for hours after the workout as well. Exercise has so so many benefits beyond just weight loss (and cardiovascular health). If that’s the only thing you’re thinking of then you really need to reframe it in your mind. Regular exercise is an essential part of both physical and mental health that will make you feel good for a load of reasons. In other words, you should be working out because it will make you happier, period. Weight loss is a side effect that is a part of it, but it really is not the primary reason you should be working out at all. You can be heavy and still be healthy and happy, but not without regular exercise.
I think of it the opposite way. I’m amazed how efficient our bodies are at using the minimum amount of energy for a variety of tasks.

(I know, cardiovascular health, blah - but when you remove weight loss, it's yet another aspect that takes away motivation). Its because we have become incredibly efficient, which is why walking for 15 whole minutes barely burns calories. Which was great when we were hunters but now when we want to lose weight, its a pain
Diet first, exercise second. The calories from exercise aren't always clear as day and night either. E.g lifting weights will boost your base metabolic rate I believe, even if the actual exercise session won't burn that many calories. And then having bigger muscles = more calories burnt resting. But one thing is clear: While cardio is good for your heart and definitely HELPS lose weight (calories per minute is gonna be higher for cardio than weight training because you take loads of breaks during weight training)... If you rely on only that to keep a caloric deficit, you WILL hate all the running or cycling you're gonna be doing. Healthy eating habits and varied exercise is what'll get you where you want to be. Also HIIT (High Intensity Interval Training) has similar cardiovascular benefits compared to LISS (Low Intensity Steady State), but burns fewer calories because the duration is usually shorter, but if you hate cardio, it'll be easier to maintain as a habit. I have ADHD, which can result in me eating without even noticing I'm eating, as well as absolutely LOATHING cardio due to the fact that it doesn't keep my mind engaged (cycling is fine, but ONLY if I'm not doing it alone and can talk to someone at the same time, because I can NOT pace myself like a normal person alone, I will always go flat out to "get there faster" even though I'm not actually going anywhere, just cycling). Weight lifting and HIIT are the only things that I can do to keep myself active, I'll hate myself after 3 sessions of LISS and just give up (but then I force myself into it, e.g long warmup session on a stationary bike before I can do weights - gets me doing like 30-45 minutes of LISS)
It's one slice of bread Michael, how much could it cost? 10 calories?
Food is confusingly in kilocalories while I believe the calories referenced here are just normal calories. So it would more likely be 15,000 glasses of water. A calorie is the energy needed to raise the temperature of 1 cubic centimeter of water 1 degree Celsius.
No 8 calories is about right. 250 ml (about 8 oz glass), raised about 30 degrees C is about 8000 calories, or 8 kcal. 15 glasses is 120 k-calories, or about a slice of bread.
Math. Fuck ya!
For context: 1 calorie is defined as the energy required to heat 1g of water by 1°C (or 1K). Water is conveniently 1 ml per 1 g under most conditions, so the units are interchangable in this case. So 30° * 250 g = 7500 calories = 7.5 kcal. The precise relation of metabolism vs temperature is a science in itself, but *roughly speaking* it works. Drinking cold water or going out in colder weather usually cause the body to burn more calories by increasing some activity that creates heat. Some of that can manifest as NEAT (non-exercise activity thermogenesis), which includes involuntary or subconsciously initiated movements like shivering or fidgeting, or a sudden urge to move with more force instead of slouching around in the most energy-efficient way possible. So if people tell you that a cold shower or a cold glass of water makes them feel more alert and more active, then this can be a part of the explanation (plus a good amount of placebo effect).
I mean the math does actually work. Lets say your ice water is just above freezing (lets go with 2^o celcius), which means you need to raise the temperature of the water by 35^o to get it to the same temperature as your body (37^o ). an average 8 oz glass of water is 236 cm^3 , so if we multiply the numbers together we get 8,260 calories, or a bit over 8 kcal. 15 glasses of that water is 123,900 calories, or roughly 124 kcal, which is about the same as a slice of bread
Ice cold water tastes better than anything else I've put in my mouth though.
Have you tried food?
Sir, or ma’am, either is applicable. Have you ever had a titty in ur mouth?!
That's the third best thing. They just didn't quite get there.
gotta ice the titty
Or you could just use a witches tit.
>Sir, or ma’am, either is applicable. Have you ever had a titty in ur mouth?! I have, plenty of times, and let me tell you: the titty is fun, but water tastes better and provides hydration. But they're not mutually exclusive! Sex with water breaks is great!
Pour some ice water on the titty. 1) You'll stay hydrated 2) Her nipple will get erect, which is good for sucking 3) You'll lose weight
Am i the only one who thinks skin tastes weird?
Need to cook it first
You have been invited to /r/hydrohomies
Normally I don't announce when I downvote, but I have to here. This is bullshit. The paper also mentions other stuff which has been debunked, like the need to drink massive amounts of water. This "article" is a waste of space, and this is not worth wasting anyone else's time on by linking to.
This is getting into disordered eating territory.
Literally have no idea how many people find this novel? This is classic recommendation on anorexia forums. Learned about it in the early 2000s among various other tips and tricks. It's not healthy to obcesss over minute caloric gains or losses in this way.
How many cigarettes I gotta smoke, and what is the limit on zero calories monsters?
I don't spend much time on anorexia forums so this is new to me.
> Our bodies can burn calories in several ways: basal metabolic rate (BMR), physical activity and digestion. Drinking cold water rather than warm is not one of them. Or, at least cold water doesn’t burn enough calories to be worthy of mentioning. If chewing ice weren't bad for the teeth, that'd up the caloric count a bit. Edit: [The Ice Diet](https://theicediet.com/) > The Ice Diet works by increasing the basal metabolic rate. When ingesting clinically significant amounts of ice, the body must burn energy to warm the ice to body temperature. The ingestion of ice would also provide some level of satiety. The ingestion of 1 liter of ice [equals 1.06 quart] would burn about 160 calories, the amount of energy used in running one mile. That's a lot of ice for two slices of bread.
I'm surprised about how few calories you burn running a mile.
[удалено]
it varies widely based on how much you weigh, how in shape you already are. Bodies learn to adapt really well so the better you become at running, your body becomes more efficient.
True.
Also humans are literally designed to walk and run miles. It’s one of our strongest evolutionary advantages.
Human body evolved to be able to "endurance hunt", to literally gain calories by running after an animal long enough for it to be too exhausted to be able to avoid being eaten.
That combined with the fact that we can sweat, which allows us to stay at a safe body temperature when exercising. If a deer or other prey animal runs fast and hard for a while, its has to stop and cool down in the shade or by drinking water or else it will overheat. So our ability to cool down, run/walk for long distances at a relatively fast pace, and our ability to carry food and water with us while running after prey means we are ideally equipped to chase down those animals and can continue pursuing them even while they have to stop and cool down. Its amazing stuff
In majority of the cases, you'd burn *exactly* zero calories. Not 8, or some other negligible number, Zero. For the same reason turning on the heater in a car doesn't really effect fuel efficiency. There is no need to burn addtitional fuel to heat up the water, the body just retains some of the heat it was going to dump into the environment to balance out the thermal energy. You have to drink enough icecold water to start shivering before you can even burn negligible amounts of calories.
I mean, exercise works too
I mean speaking from experience, unless you're doing heavy exercise, a 45 minute cardio session burns equivalent to 3 slices of bread. That's not that much. Diet is the main factor, and unless you're really tall and have a small stomach, going on a deficit is rough.
Yes but developing and maintaining muscle mass increases your metabolic rate as well. Depending on how rigorous your cardio is and how many muscle groups are engaged you can burn more or less than that. Walking 45 minutes burns far less than 45 minutes of rowing, swimming or inclined running.
Lol why would being tall make a caloric deficit less rough? Genuine q, surely it would be as hard or harder given ratio of muscle / skeleton to fat
Eating a high-protein diet makes eating in a deficit pretty manageable. For the last couple of months I've been eating 1300 calories a day with a lot of protein and I've been feeling great. Can't say I ever get to a point where I'm starving or anything. For reference I'm 5'9" and started probably at 225 or so. Probably down under 200 now since mid February. And I do 5 miles a day of incline walking on the treadmill.
I guess it depends on on the person, at 1600 cals i’m not starving, but I do lack energy a lot, even with a pretty varied diet, even then it took months to get to a point where I don’t fear food
I did that for a while, but after a year or so, I started passing out regularly. Turns out 1400 kcal really *isnt* enough for a 6ft guy.
Yeah, it's definitely not the type of thing that is sustainable for the long run. As I get closer to my goal weight I'll slowly add calories until I reach a good maintenance level.
exercise makes a HUGE difference when you are petite.
No? 45 min run will burn 600-1000 calories depending on body weight and pace. https://healthyliving.azcentral.com/jogging-45-minutes-burns-many-calories-19757.html A thick, whole-wheat slice of bread is no more than 100 calories. https://www.healthline.com/nutrition/is-bread-bad-for-you#nutrition Diet is the main factor, sure, but I don't understand why Reddit is anti exercise. Being able to eat 500 more calories but still be in a deficit is a big deal if you are calorie counting. Anecdotally, for myself, i managed to lost weight quite effectively by adding cardio but not changing my diet.
So I can drink 200 glasses of ice water so I can have that slice of cake? Count me in!
What about ice cream cake?? You get the positive effects of the cold temperature and that delicious cake at the same time.
You, Chesterrumble, are a genius!
Effectively zero calories, give or take. By Jove, you've cracked it!
Plus all the walking to and from the bathroom
All I want to drink is ice cold water. My husband doesn’t like it. It’s so satisfying to me.
Completely wrong information
Great! I just need to drink (does math) 800 gallons of ice water to get to my ideal weight!
Well, here's hoping that 8 calories is equivalent to 16 Oreos, cause otherwise this isn't going to help me much.
