VIA NEGATIVA

 A

Via Negativa is one of the most powerful ideas in The Hunger Code, and honestly one of the most powerful ideas in behavioural change full stop. Let me give you the cleanest, sharpest explanation of it — the version that actually changes how you think about weight loss.

⭐ VIA NEGATIVA — THE ART OF SUBTRACTION

🔹 1. What Via Negativa means

Via Negativa = adding by subtracting.

Instead of asking “What should I do?”, you ask:

“What should I remove?”

It’s the opposite of the modern wellness industry, which tries to fix everything by adding:

• more supplements
• more superfoods
• more rules
• more apps
• more hacks

Via Negativa says:
Remove the harmful → the system heals.

⭐ 2. Why Jason Fung uses Via Negativa

Because obesity is not caused by too little good stuff — it’s caused by too much harmful stuff.

So the first two Golden Rules are pure Via Negativa:

• Do not eat UPFs
• Do not eat all the time

These two subtractions remove:

• insulin spikes
• conditioned hunger
• hedonic overeating
• food cues
• grazing behaviour
• hormonal chaos

Once those are removed, the body’s natural satiety and metabolic regulation re‑emerge.

⭐ 3. Why subtraction works better than addition

Because the human brain is terrible at adding new behaviours but excellent at stopping triggers.

Examples:

Addition approach (fails):

• “Eat more vegetables.”
• “Exercise more.”
• “Track calories.”
• “Add protein shakes.”

Via Negativa approach (works):

• Remove UPFs → hunger drops automatically
• Remove snacking → insulin falls, fat burning resumes
• Remove food cues → conditioned hunger disappears
• Remove late eating → circadian alignment improves

You don’t need willpower when the triggers are gone.

⭐ 4. Via Negativa in practice (Fung’s version)

🔸 Remove UPFs

This eliminates the biggest driver of hunger and insulin.

🔸 Remove snacking

This restores the fed–fasted cycle.

🔸 Remove late eating

This aligns with circadian biology.

🔸 Remove food cues

This stops conditioned hunger.

🔸 Remove eating outside designated places

This stops mindless grazing.

🔸 Remove “diet foods”

This removes the deprivation mindset.

🔸 Remove people who sabotage your eating

Social modelling is powerful.

⭐ 5. Why Via Negativa feels effortless

Because subtraction changes the default environment, not your willpower.

When the default is:

• no snacks
• no UPFs
• no eating outside the table
• no late meals

…then not eating becomes easier than eating.

This is exactly how the 1970s worked.

⭐ 6. The deeper philosophical point

Via Negativa is ancient — it comes from:

• Stoicism
• Taoism
• Early Christian asceticism
• Taleb’s Antifragile

The principle is universal:

Remove the harmful → the system heals itself.

This is why Fung’s approach feels intuitive, simple, and powerful.

⭐ 7. The clinical version (for your paediatric practice)

Via Negativa = remove obesogenic drivers:

• UPFs
• snacking
• food cues
• late eating
• eating in front of screens
• grazing environments
• sugary drinks

Result:

• hunger normalises
• insulin falls
• satiety returns
• behaviour becomes automatic
• weight loss becomes effortless

This is why parents understand it instantly.
