more than 24 hours per day in water. In fact, he didn't spend two hours per day swimming in,
or consuming, 50° water.
Ray Cronise's fat-loss spreadsheet. 12 weeks without cold vs. 6 weeks with cold.
Something else needed to be happening. It could have been the other thermic loads he
experimented with: cold walks, sleeping without sheets, etc.
Digging deeper still, I now believe that the "something else" involves two players you'll hear
much more about in the next few years: adiponectin and BAT.
Adiponectin is a cool little hormone, secreted by fat cells, that can both increase the oxidation
("burning") of fatty acids in mitochondria and increase uptake of glucose by muscle tissue. I
believe adiponectin is largely to thank for Ray's muscle gain.17 Speculation notwithstanding, the
research is in its early stages, so I'll reserve adiponectin as an intellectual dessert for the geeks.
My forays into its potential can be found in the online resources.
