Energy balance
AMPK acts as a cellular energy sensor that restores homeostasis by activating catabolic pathways (ATP generation) and inhibiting anabolic pathways (ATP consumption) in response to energy stress.
Your cells have a built-in energy sensor (AMPK) that switches on fat burning and turns off fat storage when energy is low. This happens naturally during fasting or exercise.

Its principal role is as an energy sensor monitoring the cellular ratios of AMP to ATP and/or ADP to ATP... it activates catabolic pathways that generate ATP while switching off nonessential ATP-requiring processes, thus acting to restore energy homeostasis.
