How to reduce visceral body fat (hidden fat)

6-minute read

Key facts

  • Visceral fat, also known as toxic fat, is hidden inside your body on and around your vital organs.
  • Visceral fat can cause health issues such as high blood pressure, heart disease, diabetes and some cancers.
  • Visceral fat is caused by eating more calories than you burn and not moving enough.
  • A waist circumference of 80cm or more for females and 94 cm or more for males could mean that you have too much visceral fat.
  • To prevent visceral fat, focus on maintaining a healthy balanced diet and keeping physically active.

What is visceral body fat?

Visceral body fat, also known as ‘toxic’ fat, is fat stored deep inside your body.

Most fat is stored underneath the skin and is known as subcutaneous fat. This is the fat that is visible and that you can feel. The rest of the fat in the body is stored around your internal organs, including your heart, liver and intestines. This is visceral fat.

Visceral fat makes chemicals and hormones that can be toxic to the body.

Visceral fat produces more of these toxic substances than subcutaneous fat, so it can be more harmful to your health. Because of this, visceral fat carries a range of health risks for everyone.

Visceral fat is more common in males than in females.
