What is dirty keto diet?

As the name implies, it's the less clean (read: less healthy) version of the OG keto diet. Here's the lowdown: On a regular keto diet (also called “strict” or “clean” keto), no more than roughly 5% of your calories should come from carbs, 75%-90% should come from fat, and the remaining 6%-25% from protein.
