Peter believes that an organized kitchen can help you lose weight! It all comes down to the way you choose to live, he says. "You can't be a lean person if your house, especially your kitchen, is full of fat. And so as the master bedroom drives the house, the kitchen nourishes the house. Not just in terms of food but in terms of your whole mental outlook," he says. "I don't believe you can separate how you live from the vision you have for the life you want."

Tip 9: Establish a "magic triangle" in your kitchen.
There are two strategies for keeping your kitchen lean and clean, Peter says. The first is to establish a "magic triangle" in your kitchen between the stove, your refrigerator and your sink. "Anything you use most often, keep it in the triangle," he says. "Anything you use less often, outside the triangle. It will save you a ton of time."

Tip 10: Identify useful utensils with the cardboard box test.
If you want to see what utensils you're really using, Peter recommends the cardboard box test. "Take all the utensils out of your drawers, put them in a cardboard box," he says. "For the next month, whenever you use one of these utensils, put it back in the drawer. If after four weeks it's still in the box, you don't need it."
