Ferris covers a few other interesting things but one of reasons I like his book so much is that he split tests every theory and idea he can find.

Haven't read the book, but I'm pretty sure cals in/cals out IS thermodynamics. Arguing for cold showers beyond the raised metabolism (which is increased cals out) would be arguing from some nonthermodynamic biological effect.
