"Metabolic" refers to the processes that occur within living organisms to maintain life. These processes include converting food into energy, building and repairing tissues, and regulating bodily functions. The term is often associated with the body's metabolism, which encompasses both catabolism (breaking down substances for energy) and anabolism (building up substances for growth). Metabolic rates can vary between individuals and are influenced by factors such as age, gender, and activity level. A higher metabolic rate means the body burns more calories at rest, while a lower rate indicates fewer calories burned. Understanding metabolism is essential for topics like nutrition, exercise, and weight management.
