The idea that restricting carbs might be good for our waistline, as well as our general health, has been around for a long time. While Dr. Robert Atkins was certainly not the first to tout this concept, the eponymous Atkins diet garnered mainstream attention when his Diet Revolution book sold millions of copies in the early ‘70s.

It’s safe to say the Atkins diet isn’t as popular as it once was. But the idea that high-fat, low-carb diets are beneficial hasn’t disappeared. Indeed, the ketogenic diet has been touted by an increasing number of athletes and industry voices in recent years. Interestingly, the keto diet is older than the Atkins diet by more than half a century.

In this article, we want to definitively answer the question: which is better, keto or Atkins? In doing so, we shall examine the key similarities and differences between the protocols; ask which diet is best for beginners, and whether either is sustainable; and ultimately help you make an informed decision.
