The term “metabolism” refers to the chemical processes occurring within the body that convert food into energy. It encompasses two main types of processes: catabolism, which breaks down nutrients to release energy, and anabolism, which uses energy to build and repair tissues. Metabolism influences how efficiently the body uses energy and can vary based on factors like age, gender, genetics, and activity level. A higher metabolic rate typically leads to greater energy expenditure, playing a crucial role in weight management and overall health.
