lose 10.7 lbs just by drinking ice-cold water

100 calories or Calories (KCalories in other parts of the world)? If it's the former, that would be 1/10th of what we know as a Calorie.

Hi guys.
A proper hydration is essential to everyone, and the best supplement to stay hydrated whether you are trying to lose weight or just keep it off is water '' the most under appreciated fluid '' but if you drink ice-cold water you can add another beneficial role : lose extra weight and stay hydrated. actually if the body wants to use that ice-cold water it must be body temperature so it use energy to get it warm, that energy is approximately 100c per day, 705 per week, 2850 per month, 33,023 per year that's 10,7 lbs per year.isn't that wonderful two birds with one stone.

Actually it's less than that if you based it on 8 eight ounce glasses of water a day. So about 70 calories. It still adds up if done over a year and no other overage happens, but I'm sure many blow that calorie burn by the time the holidays roll around.

I've heard the claim before, so I worked out the math.

1 small "c" calorie is the energy required to raise 1 g of water 1 degree C.
Let's assume that the water is at 0 C and that body temperature is 40 C.
Luckily, water is 1 g/ml, so we'll work with the fairly easy quantity of 1 liter, weighing 1 kg.

Warming 1 kg of water from 0 to 40 C requires (1000 g)*(40 C)*(1 cal/(g-C))=40,000 cal = 40 kcal or 40 Cal.

So in short, drinking 1 liter of ice water will require approximately 40 kcal. This is great, to be sure, but it's going to be in the noise for almost everyone. Most of us already drink cold drinks, so we would have to up our consumption considerably to get any noticeable benefit.

I think the link @Cherimoose is interesting. I didn't dig into it, but I do wonder how the authors claim that the beverages were in fact heated to room temperature? Are they implying that other energy expenses were reduced to provide the energy to maintain body temperature?

That sounds good on paper. In reality, there are many other variables which makes such an outcome virtually impossible.

Maybe we should just ice all of our food and eat it super cold too, to lose more weight! Yeah, that's the ticket.
