Subcutaneous Fat

Definition

Subcutaneous fat is the layer of fat stored directly under your skin. It is the fat you can feel when you pinch the skin on your arms, belly, or thighs.

Scientific / Technical Definition

Subcutaneous fat is adipose tissue located beneath the skin. It serves as energy storage, insulation to regulate body temperature, and a cushion to protect underlying muscles and bones. It differs from visceral fat, which is stored around internal organs.

Benefits

• Acts as an energy reserve for the body
• Provides insulation and helps regulate body temperature
• Prevents trauma to muscles and bones by serving as a cushion

Examples

• The pinchable fat on your arms and legs
• Fat measured via skinfold calipers in fitness assessments

Additional Information

• Importance: While subcutaneous fat is essential for normal bodily function, excessive amounts can lead to obesity, which is associated with various health issues.
