A Romulan with blood on his face. Nanoprobes assimilating blood cells. Blood is the circulatory fluid that runs through most corporeal lifeforms in the universe. Its primary function is to carry nutrients and respiratory gases to cells and to remove waste products.
Muscle is more metabolically active than fat, and building muscle can help increase your metabolism (36, 37, 38, 39). This means you will burn more calories each day, even at rest (40). Lifting weights will also help you retain muscle and combat the drop in metabolism that can occur during weight loss (41, 42, 43, 44).
Metabolism is a fancy word for how your body regulates energy consumption. Someone with a higher metabolism burns more calories even at rest than someone with a lower metabolism, and can therefore get away with eating more food âeven junk food. But a high metabolism isnât a privilege reserved for a select few who were lucky enough to be born with it. You can raise yours and reap the benefits.
