Alright, so one of my buddies told me this and I'm a little iffy about it, so here it goes: He says that drinking cold water can help one lose weight. He claimed that your body is forced to 'warm' the water up, which causes calories to be burned as your body is working to heat the water up to a suitable temp. So basically drinking cold water = burning cals.
So what do you guys think: fact or fiction?
