COLD WATER gives you what half hour of Cardio does

I can't wait to go to McDonald's to try out their new Spicy McChicken or whatever it is called. I love food, but unfortunately for me, my metabolism doesn't. Its absolutely unfair when I see my friends hogging as much, as little active as me, but yet not piling on weight like I am in final year of Med school. 

Coming to the point, some experiment has pointed out that drinking 2 litres of chilled cold water through the day will help you burn 100 additional calories. As I believe all the research and experiments that seem right and convenient to me, I chose to believe this as well. My advice to every one - drink ONLY cold water. 

Lets quantify my advice and the experiment findings now:

A friend joined a gym recently, primarily for weight loss which cost him Rs.20000 per annum.
On an average, he goes to the gym 4 days a week, does Cardio for an average of half hour, floor exercises for 10-15 minutes, and no weights because he had a fracture recently, burning about 350 calories per session. 

Now assuming he is sincere through out the year (which I'm sure he won't be):

Calorie loss in one year = 72800 kcals
Cost per 100 calories burnt = Rs.28
Time spent = 12480 minutes

Water method:

Calorie loss in one year = 36500 kcals
Cost per 100 calories burnt = Rs.0
Time spent = 0 minutes

Final result:
Follow my advice to lose 50.1% calories of an average one hour weight loss work out at the gym, but at the same time, also save money (Rs. 10020) and time (6252 minutes) calculated per annum.

  1. Pankaj it would be nice if you could post the reference of the experiment.

  2. I read this in some health magazine some time ago, but I'm not sure which one.

    They spoke about the experiment, and gave the rationale for it as below:

    Water at 0 degrees Celcius, to bring to 37 d Celcius, you need 37 kcals per 1 liter of water (1 kcal for each degree for each liter - using laws of thermodynamics)

    That makes it 74 kcals for 2 liters.

    Now consider the water that you drink at 0 degrees Celsius has only 300 grams of ice in it.

    Ice requires more calories to be burnt (latent heat of fusion)

    That would amount to:
    300 g x 0.080 Cal/g = 24 Cals (ie, 24 kcal)

    That would take your total to 98 Cals burnt per 2 litres of ice cold water.

    PS - I'll try hunting for the link to the experiment to make more sense, though you can see the chemistry behind it using laws of thermodynamics.
