                                Your basal metabolic rate (BMR), the energy your body needs at complete rest to function, accounts for roughly 60% to 70% of your daily calorie burn. This baseline is the theoretical minimum calories needed to sustain life, but intentionally consuming only this amount is dangerous and unsustainable.
