There are two types of fat in your body. One is visible. The other is invisible — and it's the more dangerous one.

Subcutaneous fat sits just under the skin. You can pinch it. It's unsightly but relatively harmless metabolically. Visceral fat, however, accumulates around internal organs — liver, pancreas, intestines. It acts as an active endocrine organ that disrupts your entire biochemistry.

🔴
Visceral fat is not just an aesthetic problem. It's associated with insulin resistance, cardiovascular disease, chronic low-grade inflammation, and hormonal imbalances. It's the type of fat that kills silently.

How to recognise excess visceral fat

Contrary to popular belief, visceral fat doesn't necessarily correspond to visible overweight. Slim people can have excess visceral fat — this is sometimes called "skinny fat".

Why visceral fat accumulates after 35

Factor 01
Declining testosterone and oestrogen
Sex hormones regulate fat distribution. Their natural decline after 35 favours visceral rather than subcutaneous storage.
Factor 02
Chronically elevated cortisol
The stress of active working life keeps cortisol high. Cortisol specifically targets visceral fat deposits to store energy in case of "danger".
Factor 03
Progressive insulin resistance
The modern diet (fast carbs, ultra-processed foods) maintains chronic hyperinsulinaemia and insulin resistance that promote fat storage, particularly abdominal.
Factor 04
Muscle loss (sarcopenia)
After 35, muscle mass naturally declines without training. Less muscle = slower metabolism = easier fat storage.

The 5 levers to reduce visceral fat

The good news: visceral fat is more responsive to training and nutrition than subcutaneous fat. It's the first to go during a well-managed fat loss programme.

Lever 01
Progressive weight training
Building muscle mass through progressive weight training increases resting metabolism and improves insulin sensitivity — both direct enemies of visceral fat.
Lever 02
Moderate caloric deficit
A deficit of 300–500 kcal/day, without extreme restriction that would trigger a cortisol response. Sustainability over speed.
Lever 03
Stress and sleep management
Reducing chronic cortisol through 7–9h sleep and active recovery practices (walking, breathing, disconnection).
Lever 04
Insulin regulation
Reduce fast carbs, increase protein and fibre, avoid constant snacking that keeps insulin permanently elevated.

What doesn't work

There is no "targeted" exercise to burn visceral fat locally. Crunches don't melt the belly. Heated belts don't either. Spot fat reduction is a physiological myth.

What works is a global reduction in body fat through a controlled caloric deficit, combined with training that preserves and builds muscle mass.
