I heard this from a guy online.... I'm not sure if he knows ANYTHING about bodybuilding nutrition, but he was under the impression that drinking ice-cold water will raise your metabolism because your body needs to "heat" the water and thus expends some energy.
I've never heard anything like that, and it doesn't compute with my logic.... I think anything ice-cold would only be heated via convection, and heat would be lost from blood in the capillaries around the mouth, oesophegus and stomach.... this would LOWER your core temperature, and thus have the OPPOSITE effect of thermogenic foods like chilli.
Also, I'm thinking that your body.... as a homeostatic response, might try to divert blood AWAY from the cold area in your stomach, to try and minimise heat loss.... and with less blood going to your working organs, that sounds like it would also drop your metabolic rate.
Any ideas on this? Sounds like a crock to me, but I thought I'd make sure before I go correcting him.....
