                                Your body burns 50-80% of its daily energy just to maintain essential functions like breathing and blood circulation, a process known as your basal metabolic rate. At its core, the meaning of metabolism in nutrition is the sum of all chemical reactions that convert the food you eat and drink into the energy required to fuel this and every other bodily function.
