Subtle movements like shivering or fidgeting can stimulate epinephrine release, increasing fat mobilization and oxidation.

“So because the new view that the modern understanding is that it's not adrenaline released systemically kind of bathing all your fat tissue, but rather its neurons releasing adrenaline epinephrin locally that in theory, exercise that stimulates the release of epinephrin or exercise coupled with things like shiver or low grade shaking movement, or the NEAT, the non-exercise activity thermogenesis could in theory lead to local enhancement of mobilization of fat tissue.”

“Those subtle movements of our core musculature, not just the core but all our limbs and our musculature, those low-level movements, they trigger epinephrine release from these neurons. They stimulate the mobilization of fat and then that fat is oxidized at higher rates.”
