 And then they measured mice's muscle growth, fat burning, and oxygen consumption during rest, as well as short-term and long-term workouts. In the mice that lacked the BNC versions, they found that those mice are essentially blind to short-term workouts. You burn less oxygen and you burn less fat. And in healthy individuals and humans, even with diabetes, the more you produce of them, the more oxygen you work and the lower body fat you have.
