Muscle Mass Higher muscle mass translates to a faster metabolism.“If someone is more active, their metabolism is increased, and they would require more calories.”Īccording to the Cleveland Clinic, the speed of your metabolism can be affected by several factors: “The average person with minimal physical activity needs about 10 calories per pound of body weight to maintain their daily functions and remain the same weight,” says Felix Spiegel, MD, a bariatric surgeon with Memorial Hermann in Houston. Griebeler says that the calories burned by daily living and doing things like sitting, eating, and breathing are referred to as nonexercise activity thermogenesis.

You’ll often hear metabolism discussed in relation to weight and weight loss, but that’s not the only reason it’s important. In simpler terms, metabolism refers to everything in the body that has to do with energy conversion: blood circulation, body temperature control, muscle contraction, food digestion, nerve and brain function, and waste removal, according to MedlinePlus. These changes create the energy and materials that cells and organisms need to grow, reproduce, and stay healthy, and also help get rid of toxic substances. Metabolism refers to the chemical changes that take place within a cell or organism, according to the National Cancer Institute.
