Body Fat Mass

Definition

The total amount of lipids stored in the body, primarily in the form of triglycerides in adipocytes, including subcutaneous and visceral fat tissue.

How it works

Body fat is not a negligible component of the human body; it fulfills essential functions such as thermal insulation, protection of organs, and hormone production. However, excessive body fat, particularly visceral fat around internal organs, increases the risk of cardiovascular and metabolic diseases.

Role

Storing energy, providing thermal insulation, and producing metabolically active hormones.

Examples

• An 80 kg man with 18% body fat possesses 14.4 kg of lipids
• A woman with 28% body fat within the healthy range
• Excessive visceral fat increasing metabolic risks.

Recommendations

Maintain an adapted body fat percentage according to age and sex through a balanced diet and regular physical activity. Prefer strength exercise to reduce body fat while preserving lean mass.

Key takeaway

A moderate body fat percentage is normal and healthy, only excess represents a risk.
