Carbohydrates have gained quite a controversial reputation in today’s time. While some people choose to obliterate it as much as possible, others choose to maintain moderate macronutrient levels in their diet.
In the midst of this, Atkins and ketogenic diets are those that aim at low-carb intake. However, they are not entirely the same thing.
Key Takeaways
- The Atkins diet focuses on high protein intake and gradually increases carbohydrate consumption, while the ketogenic diet maintains low carbohydrate levels for sustained ketosis.
- The Atkins diet follows four distinct phases, whereas the ketogenic diet does not have specific stages.
- The ketogenic diet may provide more significant weight loss and health benefits than the Atkins diet due to consistent low-carb intake.
The Atkins vs Ketogenic Diets
The difference between the Atkins and ketogenic diets is that in the Atkins diet, the carbohydrate intake of the person is increased in gradual phases to leave behind ketosis, whereas, in a ketogenic diet, the carbohydrate intake is always low, as the objective is to keep the person’s body in ketosis.
The Atkins diet focuses on gaining 30% of calories from protein-rich food. While doing so, the carbohydrate intake is increased gradually. Due to this, the person can leave the state of ketosis.
This is a situation in which the body does not have enough energy due to a lack of carbs. This diet is very popular as various foods can be incorporated into meals.
Meanwhile, a ketogenic diet focuses on gaining only 20% of calories from protein-rich food. While doing so, the carbohydrate intake is always low.
This keeps the person in a state of ketosis. For this reason, there are a lot of restrictions when it comes to food variety in meals.
Comparison Table
| Parameters of Comparison | The Atkins Diet | Ketogenic Diet |
|---|---|---|
| Carbohydrate | It increases the carb intake gradually while maintaining an overall low level. | It always maintains a low-carbohydrate intake level. |
| Protein | It focuses on gaining 30% of calories from protein-rich food. | It focuses on gaining only 20% of calories from protein-rich food. |
| Ketosis | It does not keep the body in ketosis. | It keeps the body in ketosis. |
| Food Variety | It does not have many restrictions for food variety. | It has a lot of restrictions for food variety. |
| Risks | It is supposedly not as risky in the long term. | Its long-term risks are unknown. |
What is the Atkins Diet?
Robert Atkins developed the Atkins diet in the 70s. Many called it a fad diet that would lose relevance with time.
However, it rose to popularity in 2000 and is still followed by many people. The diet has a low-carb, moderate protein approach.
Carbohydrate levels are increased at a gradual pace. However, 30% of calories are always gained from protein.
It also requires having a high fat intake.
The idea behind the diet is that the body can lose weight without being in ketosis. It has a metabolic advantage since burning fat rather than carbs allows a person to expend more calories.
This idea spread like wildfire as it allowed people to lose weight without feeling tired and out of energy the entire time.
However, all these claims were debunked in ‘Lancet’. This was a review study of the diet, which called it simple, monotonous, and nonsensical.
However, many still followed it. An analysis conducted by Forbes even found that the Atkins sample menu was among the top 5 expensive plans in the world.
In 2004, a lawsuit was filed against Robert Atkin’s company. However, it was dismissed since Robert claimed the plan was only ‘advice and ideas.’
What is Ketogenic Diet?
Unlike the former, a ketogenic diet is proven to be effective. This, too, is a low-carb diet.
However, it does not increase the carbs levels at all and requires the body to be in ketosis. While doing so, 20% of the calories in the diet must come from proteins.
The diet must have high levels of fat as well.
The ketogenic diet was first devised in the 1920s. However, it failed to become popular at that time.
Despite this, it was found that this diet may be helpful in cancer treatment, epilepsy, Alzheimer’s disease, Parkinson’s disease, autism, and even sleeping disorders.
However, the diet scares people due to its restrictions. There are not a lot of foods that fall under the category of being suitable for ketosis.
Therefore, there are a lot of restrictions on the sources from which the person must derive nutrients. Another limitation is that people feel persistently tired due to being in a state of ketosis.
Regardless, unlike the Atkins diet, this diet is proven effective. Even though long-term risks are still unknown, it is followed by many people worldwide.
Several organizations hand out diet plans and even cook meals for the same.

The article does a great job of breaking down the differences between the Atkins and Ketogenic diets. However, the long-term health risks of the two approaches should be more thoroughly explored.
The breakdown of the Atkins and Ketogenic diets is very informative. The comparison table makes it easy to grasp the key differences between the two dietary approaches.
The comparison table is really helpful in understanding the different aspects of both diets. However, more sources could be cited to validate the information provided.
I appreciate the objective description of both diets. It’s great to see the risks and benefits of each diet laid out so clearly.
The article provides a good understanding of the Atkins and Ketogenic diets. However, I would have liked to see a more detailed examination of the potential health effects of each approach.
This is a comprehensive breakdown of the Atkins and Ketogenic diets. However, it would be interesting to explore some scientific studies that support the claims being made.
This article provides very valuable information. The comparison table is particularly useful.
Very well written and informative piece. It is well laid out and easy to understand.
