The term "metabolic rate" refers to the rate at which the body converts food into energy. This process involves the metabolism of nutrients and is crucial for maintaining bodily functions, including digestion, circulation, and temperature regulation. Metabolic rate can vary based on factors such as age, gender, body composition, and activity level. There are two primary components: basal metabolic rate (BMR), which is the energy expended at rest, and the energy spent during physical activities. Understanding metabolic rate is essential for optimizing weight management and nutrition strategies.
