The term "metabolism" refers to the chemical processes that occur within the body to convert food into energy. This encompasses both anabolism, which builds up molecules for growth and repair, and catabolism, which breaks down molecules to release energy. Metabolism affects factors such as weight management, energy levels, and overall health. A healthy metabolism is influenced by various aspects, including age, gender, muscle mass, and the type of diet consumed, impacting how efficiently the body utilizes nutrients.
