Supermarket shopping made smarter: the simple method that cuts waste and helps you save more

Who hasn't left a supermarket with a cart full of products... but nothing coherent to prepare real meals? Between impulse purchases and quickly forgotten lists, we often end up with cluttered cupboards and a ballooning budget. However, a simple trick popularized on social networks could well revolutionize the way you do your shopping.
The 5-4-3-2-1 rule: a structured basket in the blink of an eye
The brainchild of chef and content creator Will Coleman, this now-viral method involves organizing your basket into five specific categories:
- 5 seasonal vegetables,
- 4 fruits,
- 3 protein sources (fish, eggs, meat, tofu, legumes, etc.),
- 2 starchy foods (rice, pasta, potatoes, quinoa...),
- 1 pleasure ingredient, whether sweet (a little chocolate) or savoury (a cheese, for example).
With this simple formula, he claims to be able to prepare 4 to 6 balanced meals for two people.
Why does it work?
This rule works for two reasons:
- Clarity and balance: you leave with the basics you need to compose complete meals, without having to think too long.
- Less waste: rather than buying randomly, you limit your purchases to what you really need. The result: fewer products lying around and ending up in the garbage can.
It's a bit like a simplified version of the famous "5 fruits and vegetables a day", but adapted to the organization of meals over a week.
How can you adapt it to your habits?
Of course, the rule is not set in stone: vegetarians can replace animal proteins with more legumes, and athletes can add an extra portion of starchy foods. In winter, the vegetables chosen will not be the same as in summer. The idea is to have a flexible grid, easy to personalize.
Less stress, more satisfaction
As well as saving money, this method has another advantage: it simplifies everyday cooking. You already know that everything in your basket can be combined to create varied, nourishing dishes. No more wondering at 7 p.m. "What's for dinner tonight"?
