It is now common knowledge that having too much fat is bad for you, but less well known is the serious threat posed by the "hidden fat" that surrounds our vital organs. New research published in the journal Nature Cell Biology claims to have discovered where this hidden, or "visceral fat," comes from.

Visceral fat and subcutaneous fat are the two main types of fat in the body. Subcutaneous fat is found directly beneath the skin - it gives our bodies cushioning and insulation and is a store of energy. Visceral fat, meanwhile, develops around the heart, intestines and vital organs.
