Research has shown that abdominal fat is the most dangerous type of fat, according to The Harvard Medical School Family Health Guide. Visceral fat which is deep inside the abdomen around the internal organs poses the most serious health risks.
Visceral obesity is linked to raised blood pressure, elevated blood sugar levels and higher cardiac risk, according to Harvard Medical School Family Health Guide. The metabolic products produced by visceral fat cells are released into the portal circulation which carries the blood to the liver. Visceral fat cells that are enlarged pour free fatty acids into the liver. These acids also accumulate in the pancreas, heart and other organs that are not designed to store fat, which results in organ dysfunction, according to The Harvard Medical School Family Health Guide.
