What Causes Belly Fat and How Do You Get Rid of It?

Belly fat is one of the most common and frustrating health concerns. For many people, it feels like the last place fat leaves and the first place it accumulates. But not all belly fat is the same, and understanding what causes it is the first step toward reducing it effectively.

This article explains what causes belly fat and how to get rid of it, and why measuring it accurately with a Dexa Scan is critical for real progress.

The Two Types of Belly Fat

Belly fat includes two main types:

Subcutaneous fat

  • Located just under the skin
  • Visible and pinchable
  • Primarily cosmetic

Visceral fat

  • Stored deeper around the internal organs
  • Linked to metabolic risk
  • Associated with inflammation and insulin resistance

You cannot tell how much visceral fat you have by looking in the mirror. That requires accurate measurement.

What Causes Belly Fat?

Belly fat accumulation is influenced by multiple factors.

1. Excess Calorie Intake

Consistently consuming more calories than you burn leads to fat storage. Refined carbohydrates, sugary drinks, and processed foods tend to promote abdominal fat accumulation.

2. Hormonal Factors

Hormones influence where fat is stored.

Elevated cortisol from chronic stress can increase abdominal fat storage. Insulin resistance also promotes visceral fat accumulation.

3. Lack of Resistance Training

Without strength training, lean muscle mass declines over time. Lower muscle mass reduces metabolic rate, making fat accumulation easier, particularly around the abdomen.

4. Poor Sleep

Sleep deprivation alters hunger hormones and increases cravings, often leading to increased calorie intake and abdominal fat gain.

5. Aging and Reduced Activity

As activity levels decline and metabolism slows with age, belly fat becomes easier to accumulate unless muscle mass is actively maintained.

Why Belly Fat Is More Than a Cosmetic Issue

Excess belly fat, especially visceral fat, is associated with:

  • Increased cardiovascular risk
  • Higher blood sugar levels
  • Elevated inflammation
  • Reduced metabolic flexibility

For athletes and active individuals, excess abdominal fat can also reduce movement efficiency and endurance.

How to Get Rid of Belly Fat

Reducing belly fat requires a structured and sustainable approach.

1. Strength Training

Resistance training preserves and builds lean muscle mass, which increases resting metabolic rate and improves insulin sensitivity.

Maintaining muscle is critical for long-term fat loss.

2. Moderate Calorie Deficit

A small, consistent calorie deficit helps reduce fat mass without sacrificing muscle.

Aggressive dieting can lead to muscle loss, which slows metabolism and makes fat regain more likely.

3. High-Intensity Conditioning

Interval training can improve metabolic health and support abdominal fat reduction when combined with strength training.

4. Stress Management and Sleep Optimization

Lowering chronic stress and improving sleep quality can reduce cortisol-driven fat storage and improve appetite regulation.

Why You Should Measure Belly Fat Accurately

Waist measurements and scale weight do not distinguish between subcutaneous and visceral fat.

A Dexa Scan provides:

  • Precise visceral fat measurement
  • Total body fat percentage
  • Lean muscle mass tracking
  • Bone mineral density data

This allows you to see whether belly fat reduction is actually occurring, rather than guessing.

For meaningful tracking:

  • A Dexa Scan should be done monthly
  • Every other month at minimum
  • Never less frequent than that when actively reducing belly fat

The scan itself takes about six minutes, and full body composition Dexa scans are not covered by insurance, making them a proactive health investment.

Sustainable Belly Fat Reduction Requires Data

Getting rid of belly fat is not about spot reduction or extreme dieting. It requires:

  • Preserving lean muscle
  • Managing total fat mass
  • Reducing visceral fat specifically
  • Tracking progress objectively

When changes are measured accurately, adjustments can be made before plateaus occur.
