We've all heard the classic advice: don't hit the supermarket on an empty stomach. But science shows it's even more critical than you think—hunger doesn't just lead to extra groceries; it tempts you toward unnecessary impulse buys across the board.
Hungry shoppers grab non-food items too
Researchers at the University of Minnesota found that hunger increases the temptation for everyday items like paper clips—things you don't need daily.
The Study Method
Half the participants enjoyed cake before shopping, while the others went hungry. The hungry group was 70% more likely to add paper clips to their list.
Real-World Proof
In a department store follow-up, researchers reviewed receipts and surveyed shoppers on hunger levels. Hungry customers spent 60% more on average.
