The myth that muscle is heavier than fat likely stems from a difference that does exist between fat vs muscle: density. Muscle is denser than fat, which means that if you have one pound of each ...
This makes muscle tissue approximately 15% denser than fat tissue. Skeletal muscle is a highly oxygen-consuming tissue, and oxidative DNA damage that is induced by reactive oxygen species tends to accumulate with age. [13] The oxidative DNA damage 8-OHdG accumulates in heart and skeletal muscle of both mouse and rat with age. [14]
The bones provide stability to the body. Muscles keep bones in place and also play a role in the movement of bones. To allow motion, different bones are connected by joints. Cartilage prevents the bone ends from rubbing directly onto each other. Muscles contract to move the bone attached at the joint.
Experts explain the relation of fat and muscle on weight, how body composition effects overall health, and tips for how to gain muscle and lose fat.
In terms of tissue type, the body may be analyzed into water, fat, connective tissue, muscle, bone, etc. In terms of cell type, the body contains hundreds of different types of cells, but notably, the largest number of cells contained in a human body (though not the largest mass of cells) are not human cells, but bacteria residing in the normal ...

The selection of compartments varies by model but may include fat, bone, water, and muscle. [2] Two people of the same gender, height, and body weight may have completely different body types as a consequence of having different body compositions. This may be explained by a person having low or high body fat, dense muscles, or big bones. [3]
[2] [3] The skeletal muscle cells are much longer than in the other types of muscle tissue, and are also known as muscle fibers. [4] The tissue of a skeletal muscle is striated – having a striped appearance due to the arrangement of the sarcomeres. A skeletal muscle contains multiple fascicles – bundles of muscle fibers.
