Obviously aquiring the water is more important than solid foods in the more immediate term but if the practice is continued than it can contribute to points 1 & 2.

If it's cold enough, you can blister your mouth as well.

I've never been a fan of the BMI scale. When I was in the gym, I was 17 stone with good abs. The BMI said I was morbidly obese!!! I was going through an easy 3000 calories a day.

It's better to measure bodyfat as a survival resource. Remember when David Blaine did his glass box 'trick'/stunt? He went in there FAT!

Anyway, think what Ray Mears would do. He's the only survivalist that goes into a survival situation and comes out fatter than he first went in! Now that's hardcore!!!
