HOW THEY ENGINEER ADDICTION

The term "bliss point" was coined by American market researcher and psychophysicist Howard Moskowitz in the 1970s. It describes the precise amount of an ingredient — typically sugar, salt, or fat — that maximises sensory pleasure without causing the consumer to feel satisfied.

Dr Pepper once went through 61 formulas and conducted 3,904 taste tests across four US cities to find the perfect sweetness level for Cherry Vanilla Dr Pepper — engineered to hit the exact bliss point that would maximise sales. [source]

Why It Works Against You

The bliss point is specifically calibrated to be pleasurable but not satisfying. Natural foods have a built-in "stop" signal — after a certain amount, they become less appealing. But foods engineered to hit the bliss point bypass this mechanism entirely.

This is why you can eat an entire bag of crisps without feeling full, but struggle to finish a second banana. The banana triggers satiety; the crisps are designed not to.

Have you ever noticed how some snacks seem to "melt" in your mouth? That's not an accident — it's a carefully engineered property called vanishing caloric density.

The Science

Your brain uses multiple signals to determine when you've eaten enough. One key signal is the physical presence of food in your mouth. When food dissolves quickly, your brain doesn't register that you've consumed anything substantial.

Puffed snacks like Cheetos, Wotsits, and Quavers are engineered to dissolve almost instantly on contact with saliva. Despite containing significant calories, they trick your brain into thinking you haven't eaten anything at all.

The Pringles Principle

Pringles famously uses the slogan "Once you pop, you can't stop." This isn't just marketing — it's a literal description of how the product is designed to work. The uniform shape, the instant crunch-to-dissolve texture, and the precise flavour coating all combine to bypass your natural satiety signals.

Ultra-processed foods don't just taste good — they trigger the same neurological pathways as addictive drugs. This isn't hyperbole; it's what brain imaging studies consistently show.

The Reward Pathway

When you eat ultra-processed food, it triggers a massive release of dopamine — the neurotransmitter associated with pleasure and reward. This is the same chemical released when people use cocaine, nicotine, or alcohol.

The problem? Your brain wasn't designed for this level of stimulation from food. Natural foods cause a gentle dopamine release; ultra-processed foods cause a spike. Over time, your brain adapts by reducing dopamine receptors, meaning you need more of the stimulus to feel the same pleasure.

The Craving-Crash Cycle

This creates a vicious cycle: eat ultra-processed food → massive dopamine spike → crash → crave more to feel normal again. It's the same pattern seen in substance addiction, and it's happening to millions of people every day without them realising it.

Our brains naturally tire of any single distinct flavour — a phenomenon called sensory-specific satiety. It's why you feel full after a plate of chicken but suddenly have "room" for dessert. Your brain hasn't tired of sweet yet.

The Doritos Problem

Food scientists have learned to exploit this by creating products with no single dominant flavour. Doritos are the textbook example — food scientists have described them as having a flavour profile that's complex enough to be interesting but never distinct enough to trigger satiety. Your brain never gets tired of eating them because it can't pin down what it's tasting.

This is combined with dynamic contrast — the interplay of textures (crunchy coating, soft interior) that keeps your mouth engaged and prevents monotony. Ice cream with cookie pieces, chocolate with crispy centres, pizza with varied toppings — all exploit this principle.
