Metabolism is a series of chemical reactions, fueling the body with needed energy to promote biological functions and sustain life. There are two parts of metabolism: catabolism, which breaks down matter, and anabolism, which reassembles matter to produce energy-providing substances for the body. Individuals with a high metabolism experience several physical side effects.
Weight Loss
Individuals with a high metabolism may experience weight loss. As your metabolism increases, your body must find substances to fuel metabolic chemical reactions. Some individuals find that, no matter how much they eat, they cannot give the body enough fuel to perpetuate metabolic reactions fast enough. These individuals therefore experience weight loss as the body uses all the food they consume toward perpetuating metabolic reactions. To gain weight, individuals with a high metabolism engage in high protein and healthy fat diets and increase strength training, such as weight lifting, to build muscle mass.
