I try never to go shopping when hungry as I tend to buy all sorts of things I don’t need. Researchers have looked into exactly how much extra you are likely to purchase if you shop when hungry and it appears the figure is 18.6%. Shoppers who have not eaten before going shopping not only purchase much more food but also have a tendency to buy many more high calorie foods, in fact 31% more high calorie snacks. The message is clear, snack before you go shopping and you could save yourself some money as well as making healthier food choices.
