Are Keto and Atkins the Same Diet?

Can Someone Please Tell Me the Difference Between Keto and Atkins?

I recently tried the keto diet in the name of research, and pretty much all I talked about over the course of the week was keto. And more specifically, everything I couldn't eat. While my increased banter on all things low-carb probably made me a bit of a buzzkill, it actually led to an influx of keto-related questions from family, friends and colleagues. And there was one question I was asked more than any other: is there a difference between keto and Atkins?

Although I knew they were both fundamentally low-carb diets, I felt embarrassed to admit I didn't actually know the ins and outs of what made these two diets different (if there were, in fact, any differences at all). So feeling the need to investigate — mostly so I could correctly answer people's questions, but also out of my own curiosity — I set out to discover if there really is a difference between the two diets. Here's what I found out.

They Aren't Actually the Same Thing

Although both diets are by definition "ketogenic diets" (aka, low-carb diets that force the body into a state of ketosis, where it burns fat for energy), they are not exactly the same diet with two different names. The keto diet originated in 1924 and was designed by Dr. Russell Wilder initially as a non-pharmacological option for treating epilepsy. The Atkins diet came along later in the 1960s as the brainchild of Dr. Robert Coleman Atkins (where the name originates from), with the sole purpose of creating a diet that restricts carbohydrate intake to "fast-track" fat loss.

Fat Burning Is the Aim of the Game

For both diets, the pillar of their success centres around the purpose of lowering the body's carbohydrate (glycogen) intake so the body will utilise fat as an energy source, and start to break down (burn) fat stores. However, there are differences between the protocol these two diets follow in order to achieve this process. Atkins focused on a specific "introductory" phase where carbohydrates are strictly limited (normally below 15-30 grams per day) to induce ketosis. This is initially similar the keto diet, however, after this introductory phase is complete, the Atkins diet then transitions to an ongoing weight-loss stage, a pre-maintenance stage, then finally a lifetime maintenance stage, all with different nutritional requirements and breakdowns. In contrast, the keto diet maintains the same requirements from beginning to end.

Protein Is the Deal Breaker

The key difference between both diets is the nutritional breakdown and guidelines. Atkins can rely on you getting the majority of your calories from protein, whereas the keto diet centres around a moderate protein intake. Both diets follow strict nutritional protocols, but the Atkins diet offers more flexibility within the balance of food groups and therefore can be easier to follow for most people. Alternatively, food intake on the keto diet needs to be closely measured and the state of ketosis constantly monitored by the individual, making a more high-maintenance option.
