Does cold water increase metabolism slightly?

What effect does drinking hot water do?

I've read that hot water cools you down for a short period of time.
But what effect does cold water have on the body.

There is prolly a very simply answer to this one... but just wondering. thx

A calorie is the amount of energy it takes to raise the temperature of 1L of water by 1 degree C.

I'm sure you can figure out the effect on a person.

so .. one of the weight losing tips should be drink cold water whenever possible!

cuz ur body will work harder use up more energy to maintain normal body temp?

Sure. But, let's look at this rationally.

Ice water: ~35 degrees F = 1.666666 degrees C
Bringing it to body temperature: ~90 degrees F = 32.222222 degrees C. Yes, your body temperature is higher, but we'll be conservative with all numbers.

1 calorie to raise 1L water by 1 degree C.

Let's say you chug ice water, and take in 3L per day.

32.22222 - 1.666666 = 30.5555 = 30.6 calories * 3L = 91.8 calories per day.

So, chugging the ice water would bring about around 90 calories of thermic energy expenditure.

There could be some more chewed up through ATP regeneration and so on, but that's a lot more than I want to think about right now.

Over the course of a week this could be around 630 calories or so, which can add up. That's a lot of consistent water intake, though.

hence, cold water might (...will) help in weight loss (very small contribution but SOME contribution considering you are drinking water while sitting or sum other non physical activity)

I smell a new fad diet. Borris you should patent this. "drink cold water and get a six pack!!" LOL .. cuase atleast there's a slight truth to it. hahaha

LOL.

I honestly think that's been done, unfortunately.

Strange...

I was just going to ask this...no lies!

Feel free to share in my amazement, I won't mind

Actually, dietary calories are, properly speaking, kilocalories.

The effect, therefore, is far smaller than Borris indicates.

EDIT: Nevermind. I read too quickly. Borris took that into account by defining a calorie as the amount of energy necessary to heat a liter -- 1000g -- of water by 1C.

as long as the the body is doing some delta more than normal... it's a benefit.

plus since spring is almost here.. cold water will become a necessity with its feeble benefits

Does this mean I can do this in reverse to slow my metabolism down? ;) I want to be bigger.

if anything, the reverse should not work.
Lets say you intake some pretty hot water. Your body has to do some sort of work to cool it down as well. You will probably end up sweating and burning even more calories as your body's mechanism to cool down.
Think of it this way: drinking hot water is somewhat synonymous to sitting in a sauna. You dont see many bulkers sitting in saunas, expecting to save calories and slow down their metabolism.
