Where is storage fat primarily found in the body?

Storage fat is primarily found in the visceral and subcutaneous areas of the body. This type of fat serves as a source of energy and plays critical roles in hormone regulation and insulation.

Visceral fat is located around internal organs, such as the liver and intestines, and can pose health risks when accumulated in excess. Subcutaneous fat, on the other hand, is found just beneath the skin and accounts for the body's adipose tissue. This fat is generally less harmful than visceral fat but still affects overall body composition and metabolic health.

The other locations mentioned—muscle tissue, the lungs, heart, and bloodstream—are not primary sites for storage fat. While fat can be found in muscle tissue in the form of intramuscular fat, it does not function as a main reservoir of energy. The lungs and heart are not involved in fat storage at all, and while fat can circulate in the bloodstream, it is not primarily stored there.
