The concept of metabolic rate refers to the rate at which the body expends energy or burns calories to sustain basic physiological functions, including breathing, circulation, and cellular processes. Metabolic rate can be influenced by factors such as age, gender, body composition, and activity level. The basal metabolic rate (BMR) is the energy expended at rest and constitutes a significant proportion of total daily energy expenditure. Understanding one’s metabolic rate can aid in creating effective nutrition and exercise strategies for weight management.
