Most people burn glucose (from carbs) for fuel. Some go low-carb, and burn fat instead. But when one becomes cold-adapted, one can quickly and easily make the switch back and forth faster and with less waste (ie, less fat storage).
Insulin sensitivity means that food — fats, carbs, and protein — are pulled into muscle to burn as fuel or to be used as building blocks to repair or make new muscle…instead of being stored as fat, or lingering in the system and leading to high blood glucose, high triglycerides, and eventually causing disease.
Cold thermogenesis causes mitochondrial biogenesis. This means that your cells can quickly switch from burning either carbs or fats, while producing fewer free radicals that can damage DNA and possibly lead to cancer formation.
During the original ketosis experiment, and again during the “Body Recomp” experiment, it was shown that Cool Fat Burner sessions could greatly speed up the acquiring of the ketogenic state.
What’s more, this transition is always smooth and without problem; none of the so-called “low carb flu” so many complain of.
The “Body Recomp” experiment is a tale in metabolic efficiency. The ability to eat both carbs and fats and lots of them, yet continue to burn body fat, while building muscle, all while showing perfect immune system, cardiovascular, inflammation, and even genetic markers.
NOTE: we are NOT talking about the ‘bad’ type of “metabolic efficiency” where one’s metabolism slows down and losing fat and building muscle gets harder! That’s the sort of thing that happens to those who engage in too much chronic cardio simultaneously with long term calorie restriction. What we’re talking about here is the opposite of that kind of “metabolic efficiency.”
