Shop the Edges, Plan the Middle
Insight
The supermarket is designed so that the food you planned to buy and the food you end up buying are different lists. Willpower at the shelf is the hardest place to spend it — so don't.
Why it works
Decisions made in the kitchen with a full stomach and a list are better decisions than decisions made under supermarket lighting with a hungry stomach. The plan decides; the shop just executes.
Practical takeaway
Before your next shop, plan the week's dinners and write the list from the plan. Shop the edges — produce, protein, dairy — and treat the middle aisles as a targeted visit, not a tour.
Good question to ask someone
When does your food environment get decided — in the kitchen, or at the shelf?
