It sounds simple enough, but have you ever thought about whether the food in your cart is as well-proportioned as your plate? "If you are aiming to make half your plate fruits and veggies, then half of your cart should be fruits and veggies, too," Melissa told POPSUGAR. The rest of your cart should be split evenly between whole grains or starchy vegetables (like potatoes and sweet potatoes) and protein.
If you're on the keto diet, you may swap out the whole grains and potatoes for avocados and nonstarchy vegetables. If you're vegetarian, you might throw some plant-based proteins like beans and tofu in your cart. Even though your cart may look a little different depending on your diet, the basic principles of this shopping method are pretty much universal.
