What Are the Atkins and Keto Diets?
Before diving into specifics, it’s important to understand the fundamentals of both diets.
Atkins Diet
The Atkins Diet, created in the 1970s, focuses on carbohydrate restriction while providing flexibility over time. It encourages starting with a low intake of carbs per day during the induction phase, and then gradually increasing carbohydrate consumption through different phases. This phased approach allows for greater flexibility in food choices, making it appealing to those who prefer a long-term, adaptable eating plan.
Phases of the Atkins Diet
The Atkins Diet is divided into four distinct phases, each designed to guide you through the process of carb management and maintenance:
- Induction phase (Phase 1): The strictest phase, limiting your daily intake to 20-25 grams of net carbs primarily from non-starchy vegetables. It focuses on high-fat, moderate-protein, and very low-carb foods, similar to the keto diet approach.
- Balancing phase (Phase 2): You gradually increase your carb intake to 25-50 grams per day, incorporating foods like nuts, berries, and even some low-fat dairy products like Greek yogurt.
- Pre-maintenance phase (Phase 3): As you progress, this phase allows for a slow increase in carb intake by about 10 grams per week. The goal is to find the right balance of carbs that suits your personal needs while preparing for long-term eating habits.
- Maintenance phase (Phase 4): In this final phase, the focus is on maintaining your eating habits over the long term. You have more flexibility with your food choices, but it remains important to monitor your carb intake to support your dietary goals.

Keto Diet
It is all about keeping your carb intake consistently low to keep your body in a state of ketosis. Ketosis is when your body burns fat for fuel instead of carbs, leading to that coveted fat-burning mode. With keto, it’s a high-fat, moderate-protein, very low-carb approach that doesn’t change as you go along. The goal is to stay in ketosis, so your body becomes a fat-burning machine.
The standard keto diet involves a very low-carb (5-10%), moderate-protein (20-25%), and high-fat (70-75%) approach to maintain ketosis. This typically requires keeping total carb intake between 20 to 50 grams per day.

Similarities Between Atkins and Keto Diets
Both the Keto Diet and the Atkins Diet share foundational elements:
- They are both low-carbohydrate diets that focus on reducing carb intake and increasing fat consumption as part of a structured eating plan.
- Both diets encourage eating nutrient-rich foods like low-carb vegetables, lean meats, and healthy fats, such as olive oil.
- They also focus on reducing refined carbs like sugary drinks and processed foods, which are common in the American diet.
Key Differences Between Atkins and Keto Diets
Now, let’s get into the nitty-gritty of what sets these two diets apart.
1. Carb Intake
With Atkins, your carb restriction starts strict but eases as you move through the phases, eventually allowing up to 100 grams of carbs daily in the maintenance phase. This flexibility makes Atkins ideal for those who want a more varied diet plan over time.
In contrast, the Keto Diet keeps your carbs per day low, usually between 20-50 grams, consistently. This helps keep your body in continuous ketosis, making Keto a better choice for people looking for sustained fat burning.
2. Protein Intake
Atkins allows more protein in its early phases, making it easier for those who want to build muscle or prefer high-protein meals. Keto, however, requires you to moderate protein consumption because too much protein can kick you out of ketosis. For those following Keto, the balance of macronutrients is crucial to maintaining the desired lifestyle.
3. Fat Intake
While both diets are high in fat, Keto requires a higher fat intake to keep your body in ketosis, meaning that about 70-75% of your daily calories come from fat. This includes foods like avocados, olive oil, and fatty meats.
On Atkins, you consume less fat as you progress, allowing for more flexibility in your diet without needing to focus heavily on high-fat foods. However, early on, the high-fat, low-carb structure of Atkins mirrors that of Keto.
Who Should Choose Which Diet?
Both diets can have potential health benefits, but long-term results depend on how they fit into your lifestyle.
- Some people choose the keto diet to focus on low-carb, high-fat eating patterns. It’s important, however, to ensure a balanced intake of nutrients by incorporating a variety of food groups, as overly restrictive eating may limit essential nutrients
- Atkins, with its gradual reintroduction of carbs, might be a better choice for people looking for a flexible, long-term plan that avoids drastic restrictions. However, like any restrictive diet, it’s essential to make sure you’re still getting enough nutrients from a wide range of nutritious foods.
Success Rates and Long-term Considerations
Both diets are often followed by individuals who prioritize a low-carb, high-fat lifestyle. However, it’s the long-term sustainability that can be a challenge. Keto requires sticking to a strict low-carb diet indefinitely to maintain ketosis, while Atkins offers a more flexible approach over time, which may be easier for some people.
When it comes to health outcomes, both diets reduce calories from carbohydrates and encourage the consumption of nutrient-dense fats. However, it’s important to consult with a healthcare provider to determine which diet is best for your needs.
Conclusion
Choosing between the Keto Diet and the Atkins Diet boils down to your goals and lifestyle. Keto offers consistent fat-burning through ketosis and a stricter focus on staying low-carb. Atkins provides more flexibility, gradually increasing your carb intake as you approach your wellness goals. The right diet for you is the one you can stick to, so consider your meal plans, preferences, and long-term goals when making your choice. Remember, it’s always a good idea to consult with a healthcare provider before making any major changes to your diet.
