Fact or Myth: Muscle weighs more than fat.

3 March 2010 2 Comments

Myth.

This is one of the most commonly used phrases in the fitness world and it is incorrect. One pound of fat and one pound of muscle both weigh one pound. One pound of feathers and one pound of rocks both weigh one pound.  That being said, muscle is denser than fat and takes up less space. One pound of muscle also burns more calories than one pound of fat. Estimates indicate that one pound of muscle burns roughly fifty calories per day, while one pound of fat burns approximately two calories per day.

Thus, while fat and muscle weigh the same, adding extra muscle through exercise can be a powerful tool when it comes weight loss and maintenance.

    Thanks for the comment Muscle Rob but you missed what the article said. Muscle does not weigh more than fat; that’s a myth. Just as a pound of feathers weighs exactly the same as a pound of fat so does a pound of muscle. They all weigh a pound.

    Muscle is definitely more dense so a pound of muscle will have less volume and will be smaller than a pound of fat. Among many other things muscle also consumers more energy per pound then fat so maintaining muscle mass is important for weight loss and maintenance.
