What Is Visceral Fat Its Function and How It Affects Health

What is Visceral Fat? 

Visceral fat is the excessive accumulation of fat found in the abdominal region of the stomach. It is the extra bulgy skin that comes between your fingers when you pinch over your stomach. When we talk about “what is visceral fat”, the meaning of it can be understood from the word visceral itself. Visceral means something present on the internal side of the body beneath the skin. It is sometimes also known as organ fat or intra-abdominal fat. It is considered to be different from other types of body fat due to its harmful consequences. From the above definition, we can conclude the exact meaning of "what is visceral fat" is.

What are the Other Types of Body Fat?

There are a total of 6 types of body fat out of which one is visceral fat. Following is a list of all the different types of body fat. 

  1. White Fat

White fat is found all over the body and is one of the necessary types of body fat. It usually consists of white and large cells and hence the name comes as white fat. This fat supports the regular metabolism of the body. It especially triggers the release of various necessary hormones such as insulin, cortisol, growth hormone, estrogen, etc. The white fat levels vary accordingly with the person. High white fat levels can also lead to serious health issues like cancer, heart stroke, high blood pressure, etc. Therefore, it is always advisable to know how to reduce visceral fat.

  1. Brown Fat

This is the most primitive type of body fat found in the human body. Brown fat is found in babies as it helps in keeping their bodies warm. In the initial days of life, the body of a newborn baby burns fatty acids in order to maintain optimum body temperature. But, this fat remains in the human body even at adulthood. Brown fat can be found in the neck and shoulder area of an adult also. 

  1. Subcutaneous Fat

Subcutaneous fat is found right beneath our skin layers. It can be felt either by pinching or squeezing any part of your skin. This fat is mostly found in our thighs, stomach, arms, buttocks, etc. Our total body fat is actually calculated by measuring subcutaneous fat with the use of a caliper. This fat is necessary for our body but can also become harmful when increased to a high level.  Therefore, if this fat increases, then you should know how to reduce visceral fat. 

  1. Healthy and Essential Fat

Another category of fat involves essential fat. It is counted amongst the healthy types of body fat as they do not harm your body. This fat essentially makes up the structure of the vital organs of our body. Essential fats are found in our brain, nerves, bone marrow, etc. It serves many functions such as regulating the release of hormones, temperature regulation, and nutrient absorption, etc. 

  1. Lower Body Fat

This is the fat that is responsible for the pear-shaped body of an adult. It gets accumulated in the lower parts of the body such as buttocks, thighs, etc, and is mostly found in women. 

What Causes Visceral Fat?

Before we get into the process of how to eliminate visceral fat, it is first necessary to understand its cause. The following are the reasons behind the rise of visceral fat in anyone's body. 

  1. Poor Eating Habits- A diet rich in carbohydrates can increase the levels of visceral fat. 

  2. Genetics- In many cases, genetics have been found to be responsible for the accumulation of fat. 

  3. Excessive Intake of Alcohol- Alcohol lowers the rate of metabolism that gives rise to high-fat levels in the body.

What are The Different Ranges of Visceral Fat?

Based on the amount of visceral fat present in the belly of a person, the categories are as follows:-

  • Normal/Admissible Range- Visceral fat levels ranging between 0 to 12 are normal. 

  • Harmful Range- People with visceral fat levels more than 13 are a matter of concern. 

How to Reduce Visceral Fat?

For people suffering from high visceral fat levels, how to get rid of visceral fat is their biggest issue. But, the real answer to how to decrease visceral fat lies in the simplest hacks only. The following are some of the tips that help in reducing visceral fat levels. 

  • Exercise daily

  • Eat a protein-rich diet

  • Take an adequate amount of sleep

  • Do not eat junk food

  • Minimize the consumption of alcohol

  • Avoid taking stress

Fun Fact 

Did you know that people with more high levels of visceral fat are said to have a “beer belly”? A few scientific researchers are in favor of this statement. They have found out that people suffering from this condition are prone to drinking beer. This eventually triggers the levels of visceral fat. Amongst all the professions, people who are into aerobics have the least probability of getting high visceral fat levels.

FAQs on Visceral Fat in Humans Structure Function and Risks

1. What is visceral fat?

Visceral fat is fat stored deep inside the abdominal cavity around internal organs such as the liver, pancreas, and intestines. Unlike subcutaneous fat, which lies under the skin, visceral fat surrounds vital organs and is metabolically active. It plays a role in hormone production and inflammation, and excess visceral fat is strongly linked to metabolic diseases.

2. Where is visceral fat located in the body?

Visceral fat is located inside the abdominal cavity, packed between and around major organs. It is found:

  • Surrounding the liver
  • Around the pancreas
  • Between the intestines
  • Near other abdominal organs
This deep abdominal fat cannot be seen directly but contributes to increased waist circumference and a protruding abdomen.

3. What is the difference between visceral fat and subcutaneous fat?

The main difference is that visceral fat surrounds internal organs, while subcutaneous fat lies under the skin. Key differences include:

  • Location: Visceral fat is deep in the abdomen; subcutaneous fat is beneath the skin.
  • Metabolic activity: Visceral fat is more hormonally active.
  • Health risk: Excess visceral fat is more strongly linked to heart disease and diabetes.
Subcutaneous fat can be pinched, whereas visceral fat cannot.

4. Why is visceral fat considered dangerous?

Visceral fat is considered dangerous because it increases the risk of cardiovascular disease, type 2 diabetes, and metabolic syndrome. It releases:

  • Inflammatory cytokines
  • Excess free fatty acids
  • Hormones that affect insulin sensitivity
These substances disrupt normal metabolism and contribute to chronic inflammation and insulin resistance.

5. How does visceral fat affect metabolism?

Visceral fat affects metabolism by promoting insulin resistance and systemic inflammation. It does this by:

  • Releasing free fatty acids into the portal circulation leading to the liver
  • Increasing inflammatory signaling molecules
  • Altering normal glucose and lipid metabolism
These changes raise blood sugar and cholesterol levels, increasing metabolic disease risk.

6. How is visceral fat measured?

Visceral fat is measured most accurately using CT (computed tomography) scans or MRI (magnetic resonance imaging). Other common methods include:

  • Waist circumference measurement
  • Waist-to-hip ratio
  • Advanced body composition scans such as DEXA
Imaging techniques provide the most precise assessment of deep abdominal fat.

7. What causes excess visceral fat to accumulate?

Excess visceral fat accumulates due to a combination of caloric surplus, hormonal factors, genetics, and physical inactivity. Major contributors include:

  • High intake of refined carbohydrates and saturated fats
  • Sedentary lifestyle
  • Chronic stress and elevated cortisol
  • Aging-related hormonal changes
These factors promote fat storage in the abdominal cavity.

8. Can visceral fat be reduced?

Yes, visceral fat can be reduced through regular physical activity, balanced nutrition, and lifestyle changes. Effective strategies include:

  • Aerobic exercise such as brisk walking or running
  • Strength training to increase muscle mass
  • Reducing added sugars and processed foods
  • Improving sleep and stress management
Visceral fat often responds more quickly to lifestyle changes than subcutaneous fat.

9. What hormones are associated with visceral fat?

Visceral fat is associated with hormones such as insulin, cortisol, leptin, and adiponectin. Specifically:

  • High insulin promotes fat storage
  • Elevated cortisol encourages abdominal fat deposition
  • Altered leptin signaling affects appetite regulation
  • Reduced adiponectin impairs insulin sensitivity
These hormonal interactions influence fat distribution and metabolic health.

10. What health conditions are linked to high visceral fat?

High visceral fat is strongly linked to type 2 diabetes, hypertension, atherosclerosis, and non-alcoholic fatty liver disease. It contributes to:

  • Insulin resistance
  • Chronic low-grade inflammation
  • Elevated blood lipids
  • Increased risk of heart attack and stroke
Reducing visceral fat significantly lowers the risk of these metabolic and cardiovascular disorders.
