Keto Vs Atkins Diet: Which One To Choose
The keto and Atkins diets are two of the most popular low-carb diets known for their effectiveness in weight loss and health improvement. While they share some similarities, they also have key differences that make one more suitable for you, depending on your goals and lifestyle.
Overview of the Diets
Keto Diet:
The ketogenic diet, also known as the keto diet, is a dietary plan that promotes ketosis, a metabolic state in which the body burns fat as its primary fuel source rather than carbohydrates.
Typically, the keto diet demands you to take less than 50 grams of carbohydrates per day, with approximately 70-75% of your daily calories coming from fat, 20-25% from protein, and just five to ten.
Atkins Diet:
The Atkins diet, created by Dr. Robert Atkins in the 1970s, is another low-carb, high-fat diet. It is structured in four phases, starting with a deficient carbohydrate intake (20 grams per day) in the Induction phase and gradually increasing carb intake as you progress through the phases.
The Atkins diet does not have as many restrictions regarding protein and carbohydrate consumption as the keto diet, making it easier for some people to follow long-term.
Critical Differences Between Keto and Atkins
Keto: Strictly limits carbs to below 50 grams daily to maintain ketosis.
Atkins: Starts with a low carb intake but gradually increases the amount allowed.
Keto: Emphasizes high fat intake to maintain ketosis.
Atkins: Allows for a higher protein intake and gradually reintroduces carbs, making it less restrictive.
Keto: Consistent low-carb intake with a focus on maintaining ketosis.
Atkins: Four phases with varying carb levels, from very low to moderate.
Health Benefits and Risks
Keto Diet Benefits:

Keto Diet Risks:
- In the early stages, patients may experience "Keto flu" signs like fatigue, nausea, and headaches (3).
- High fat intake might increase the risk of heart disease if unhealthy fats are consumed.
- It is not ideal for long-term use due to its restrictive nature.
Atkins Diet Benefits:

Which Diet is Better for You?
Choosing between the keto and Atkins diets depends on your goals and preferences.
- For Rapid Weight Loss: The keto diet might be more suitable due to its strict carb limitation and ability to induce ketosis quickly.
- For Long-Term Weight Management: The Atkins diet could be a better choice because of its flexibility and gradual approach to reintroducing carbs.
Related Studies:
- A 2020 meta-analysis of 38 studies found that low-carb diets, including keto, led to a small but significant weight loss compared to low-fat diets.
- A 6-week ketogenic diet trial in participants with mild cognitive impairment resulted in improved memory compared to the control group.
- The keto diet may lead to adverse side effects like constipation, fatigue, low blood sugar, nausea, vomiting, and headaches, especially at the beginning as the body adjusts.
- Some studies show improvements in cholesterol levels on low-carb diets like Atkins, though more research is needed on long-term effects.
- The Atkins diet has been demonstrated to improve blood sugar management for type 2 diabetes patients, at least in the short term.
Final Thoughts
The keto and Atkins diets offer significant weight loss potential and health benefits. However, they also come with potential risks and side effects.
Speaking to a doctor before beginning either diet is essential, especially if you have previous health conditions. Finally, a well-balanced diet rich in nutrient-dense foods is the most efficient way to keep an average weight and promote overall wellness.
FAQs
Here are some frequently asked questions about the ketogenic and Atkins diets:
Is the ketogenic diet the same as the Atkins?
No, they are different. The two diets differ because they are more restrictive and emphasize high-fat consumption to achieve a metabolic state called ketosis.
On the other hand, the Atkins diet allows for more protein and carbohydrates, with different phases permitting varying quantities of each.
Can I follow the keto or Atkins diets if I am vegetarian or vegan?
Yes, both diets can be followed, vegetarian or vegan. Plant-based fat sources like avocado, nuts, and seeds can replace animal-based fats like butter and cheese for the keto diet.
For the Atkins diet, protein alternatives that are vegetarian or vegan, such as tofu, tempeh, and seitan, can be substituted.
Are there any risks associated with the keto or Atkins diets?
Yes, both diets carry potential risks. Some people may experience headaches, nausea, or constipation after beginning these diets.
Furthermore, both diets can be high in saturated fats that, when consumed excessively, may increase the risk of heart disease. Talking to a medical physician before embarking on a new diet is crucial to assess potential risks and benefits.
Can the ketogenic or Atkins diet be used to lose weight?
Yes, both diets can be effective for weight loss. The high fat and protein content in these diets may contribute to a sense of satisfaction and reduce overall calorie intake. However, weight loss results can vary, and these diets may only be sustainable long-term for some.
