wow, this is so interesting, as the water with meals is so condemned all over! I'm very glad I asked you this, as I had noticed myself how better I feel when I drink water while eating. Does it make any sensible difference whether the water is hot or room temperature?
Not really. Regardless of being hot, cold or room temperature the temperature of the water will quickly reach body temperature. One advantage of cold water though is that the body has to burn a lot of calories to bring that water up to body temperature. So I prefer cold water myself even though I don't need to lose weight.
