Metabolism Myths: Muscle is the Most Metabolically Active Tissue in the Body

Whenever you talk about metabolism, the topic of building muscle always crops up. It maybe because we always hear that muscle is the most metabolically active tissue in the body.

If you really want to increase your metabolic rate, you should know what does the trick.

Metabolic rate is determined by the amount of fat-free mass in you body.

Fat-free Mass (FFM) is made up of internal organs, muscle, and bone. a pound of bone increases metabolic rate by one calorie, not a very significant amount. For “big boned” people, naturally you have increased metabolic rates compared to “small boned” individuals.

Going back to the most metabolically active tissues in the body, Dr. Mark Dedomenico sets the record straight in his blog “Building Muscle Significantly Increases Metabolism.”

Contrary to popular belief, it’s not the muscles that are the most metabolically active tissues in the body. It’s actually our internal organs. A pound can increase metabolic rate by as much as 24.4 calories per day.

According to Dr. Dedomenico, this is actually the reason why obese people have higher metabolic rates than lean individuals (even their bodies would suggest otherwise). The bigger an individual is in terms of body mass, the larger his or her internal organs will grow to supply blood. Eliminate toxins, and continue the metabolic processes in general. Basically the bigger the person, the more work it takes to keep them alive. Before you get any ideas into your head, Dr. Dedomenico warns that the heavier you are, the more taxing it is on the internal organs, resulting in a shorter shelf life.
