So what exactly does someone on a Ketogenic diet eat? I was a little baffled on this in the beginning too. Is it like the Atkins diet that was so popular several years ago when people ate all protein and could eat copious amounts of bacon and butter? Well, I guess it’s similar but technically the Keto diet should be all veggies and healthy fats like avocado, olive oil, seeds, nuts and a healthy source protein like eggs, fish and meat. What you can’t have is carbohydrates like wheat, corn, rice, potatoes or beans. Most fruits are not allowed either with the exception of berries.
