Hiding Junk Food

Brian Wansink’s research at Cornell (since replicated in various forms) found that people eat more of whatever food is visible and within reach — and less of whatever is hidden or inconvenient to access. Office workers ate significantly fewer chocolates when the dish was opaque versus transparent, and even fewer when it was placed two meters away versus on the desk. The food was identical. Only the friction changed.

This is called the visibility and proximity effect, and it operates beneath conscious awareness. You do not decide to snack more because you see a bag of crisps on the counter. You just find yourself eating them. The decision happened before you were aware you were making one.

The application is straightforward: increase the friction of bad choices and decrease the friction of good ones.

Practically, this means:

• Move processed snacks to high or inconvenient shelves, or out of the kitchen entirely
• Keep fruit, pre-cut vegetables, and protein sources at eye level in the fridge
• Decant junk food into opaque containers (the “effort to open” often breaks the automatic reach)
• Do not keep trigger foods in your immediate living space — if they are in the house, they will be eaten eventually
• Prep healthy snacks in advance so they are the low-effort option when hunger hits

This is not about deprivation. You can still eat the things you enjoy — just create a small speed bump between impulse and action. That extra 30 seconds of effort is often enough for your prefrontal cortex to catch up and make a deliberate choice.

The goal is not a perfect environment. It is a slightly better one — one that quietly stacks the odds in your favor every single day.
