If you're about to start the keto diet [1], you're going to want to make sure you know all the foods you can and cannot eat [2]. Say goodbye to pizza, unless you buy the keto-approved pizza Halle Berry loves [3], get ready to eat more fats [4], and don't forget you still need to eat at least five servings of non-starchy vegetables [5] a day to achieve nutritional ketosis [6].

As you may have heard: the first few weeks on the keto diet can be hard [7]. To make your transition easier, stock up on these keto-approved foods from Costco recommended by Anna Barnwell, MPH, clinical team member at Virta Health [8] in a blog post [9] on its site. Grab a pencil and a piece of paper, or open the notes app on your phone, and start writing out your own keto-approved grocery list now [10]!
