What’s the Difference Between Body Fat and Visceral Fat?

Not all body fat is the same. Two people can have the same body fat percentage and very different health risks. The key difference is where fat is stored inside the body.

Understanding the difference between body fat and visceral fat is essential if your goal is better health, improved performance, and long term longevity. At Kalos, we use DEXA Scan data to help clients see not just how much fat they have, but where it is located and why that matters.

What Is Body Fat?

Body fat refers to all fat tissue in the body.

This includes:

  • Subcutaneous fat, stored under the skin
  • Visceral fat, stored around internal organs
  • Essential fat, needed for normal bodily function

When people talk about body fat percentage, they are referring to the total amount of fat relative to body weight.

What Is Subcutaneous Fat?

Subcutaneous fat is the fat you can see and pinch.

It is found:

  • Under the skin
  • Around the hips, thighs, arms, and abdomen

Subcutaneous fat affects appearance but is generally less harmful metabolically than visceral fat. In some cases, it can even play a protective role.

Losing subcutaneous fat often improves how you look, but it does not always reflect improvements in internal health.

What Is Visceral Fat?

Visceral fat is stored deep inside the abdomen, surrounding vital organs such as the liver, pancreas, and intestines.

Visceral fat is associated with:

  • Insulin resistance
  • Increased inflammation
  • Higher risk of heart disease
  • Type 2 diabetes
  • Hormonal disruption

You cannot see or pinch visceral fat. Someone can appear lean and still carry high levels of visceral fat.

Why Visceral Fat Is More Dangerous

Visceral fat behaves differently from other fat tissue.

It:

  • Releases inflammatory compounds
  • Disrupts normal hormone signalling
  • Interferes with insulin sensitivity
  • Increases cardiometabolic risk

This is why visceral fat is considered one of the strongest predictors of long term health outcomes.

Why Body Fat Percentage Alone Is Not Enough

Body fat percentage combines all fat into a single number.

The problem is that it:

  • Does not show fat distribution
  • Cannot distinguish visceral from subcutaneous fat
  • Can mask internal health risk

Two people with the same body fat percentage can have completely different visceral fat levels and health profiles.

How Visceral Fat Is Measured

Most common methods cannot accurately measure visceral fat.

The scale and BMI cannot detect it. Skinfold calipers only measure subcutaneous fat. Smart scales estimate fat using assumptions.

A DEXA Scan measures visceral fat directly and tracks how it changes over time. This provides insight that appearance and weight cannot offer.

Why Visceral Fat Often Increases With Age

As people get older, visceral fat tends to increase even if body weight stays the same.

Contributing factors include:

  • Loss of lean muscle mass
  • Hormonal changes
  • Reduced activity
  • Chronic stress
  • Poor sleep

DEXA scans often reveal rising visceral fat in people who believe they are maintaining their health because their weight has not changed.

How to Reduce Visceral Fat

Reducing visceral fat requires a different approach than simply dieting.

Effective strategies include:

  • Strength training to preserve muscle
  • Moderate calorie control rather than extreme dieting
  • Regular daily movement
  • Improved sleep quality
  • Stress management

Aggressive calorie restriction often reduces weight but does not reliably target visceral fat.

How Long Does It Take to Reduce Visceral Fat?

Visceral fat can respond relatively quickly when the right strategies are in place.

DEXA scans often show meaningful reductions within:

  • 6 to 8 weeks of consistent training and recovery
  • Sustained strength focused programs
  • Improved metabolic health

Tracking allows you to confirm progress even before visible changes occur.

The Bottom Line

Body fat and visceral fat are not the same. Subcutaneous fat affects how you look. Visceral fat affects how healthy you are.

If your goal is better health, longevity, and performance, visceral fat matters far more than the number on the scale or mirror. The only reliable way to measure it is through body composition testing.

With DEXA Scan tracking at Kalos, you can understand where fat is stored, identify hidden health risks, and track meaningful improvements over time.
