What Happened to the Atkins Diet?
The Atkins diet, popularized by Dr. Robert C. Atkins in the 1970s, has been around for decades, making it one of the most recognizable weight loss plans worldwide. However, after periods of fluctuating popularity and updates to the program, many people are now confused about its status and have wondered if there was ever a rebranding. The most common misconception is that the keto diet is the new name for the Atkins diet. This is not the case.
The truth is that the Atkins diet still exists under its original brand name, but it has evolved into a more flexible and scientifically updated lifestyle approach. The original, more restrictive format is now referred to as Atkins 20, while newer, less-strict plans like Atkins 40 were introduced to appeal to a wider audience looking for a more balanced low-carb approach. This modernization includes an increased emphasis on healthy fats, lean proteins, and fiber-rich vegetables, addressing some of the earlier criticisms of the diet's high saturated fat content.
Modern Atkins Plans: Atkins 20 and Atkins 40
To better understand the current landscape of the Atkins diet, it's helpful to look at the differences between the core plans offered today:
-
Atkins 20: This is the classic, four-phase plan, recommended for individuals who need to lose 40 pounds or more, have a large waist circumference, or are managing diabetes or prediabetes. It involves a strict induction phase to kickstart ketosis.
- Phase 1 (Induction): Limiting net carbs to 20–25 grams per day for a minimum of two weeks to initiate ketosis.
- Phase 2 (Balancing): Gradually reintroducing carbs in 5-gram increments, focusing on nutrient-dense foods like nuts and berries.
- Phase 3 (Fine-tuning): Continuing to add more food variety, such as starchy vegetables and legumes, until you are near your goal weight.
- Phase 4 (Lifetime Maintenance): Maintaining weight loss by eating a healthy balance of protein, fats, and carbs.
-
Atkins 40: A more flexible starting point for those with less weight to lose or who prefer a less restrictive regimen. It begins with 40 net carbs per day and allows for a wider variety of foods from the start, without a strict induction phase.
Atkins vs. Keto: Understanding the Real Differences
While both diets are low-carb and can induce ketosis, confusing the keto diet for the new name for the Atkins diet is a mistake. They have fundamental differences, primarily in their flexibility and macronutrient ratios.
Comparison Table: Atkins vs. Keto
| Feature | Atkins Diet | Ketogenic (Keto) Diet |
|---|---|---|
| Carb Intake | Carb intake increases in phases, starting very low (20g-40g net carbs) and increasing over time. | Carb intake is consistently very low, typically 20-50 grams net carbs per day, to maintain ketosis. |
| Macronutrient Ratio | Balanced approach emphasizing moderate protein and fat. The exact ratio changes per phase. | Strict ratio: very high fat (70-75%), moderate protein (20-25%), and very low carbs (5-10%). |
| Flexibility | More flexible and adaptable for long-term lifestyle changes, with higher carb allowances in later phases. | More rigid, with strict adherence required to stay in a state of ketosis. |
| Food Variety | Gradually reintroduces a variety of nutrient-rich carbs like berries, whole grains, and legumes in later phases. | Excludes many carb-rich fruits, grains, and legumes to keep carb count minimal. |
| Goal | Focuses on sustainable weight management by finding a personal carb balance. | Primarily focused on maintaining a constant state of ketosis for maximum fat burning. |
The Roots of the Confusion
Several factors contribute to the ongoing confusion between Atkins and keto. First, both diets leverage the body's metabolic state of ketosis, where it burns fat for energy due to a lack of carbohydrates. Secondly, the massive surge in popularity of the keto diet in recent years overshadowed other low-carb plans, leading some to perceive it as the modern successor or "rebranded" version of Atkins. Finally, the evolution of the Atkins brand itself, with new plans and a focus on convenience products like bars and shakes, moved the public perception away from the original phased structure.
An Unrelated Case of 'Atkins' Renaming
It is also worth noting a completely unrelated corporate renaming that may have added to the public's confusion. In 2023, the engineering and construction company formerly known as SNC-Lavalin rebranded and adopted the name AtkinsRéalis. This has no connection whatsoever to the diet and is a separate entity entirely.
Conclusion
In summary, there is no new name for the Atkins diet. The program created by Dr. Robert Atkins continues under its original brand name but has evolved significantly to be more flexible and scientifically sound. It now offers various plans, including the classic Atkins 20 and the more adaptable Atkins 40. The widespread belief that the ketogenic (keto) diet is a renamed version of Atkins is a common misunderstanding stemming from their shared low-carb principles. While both are effective low-carb approaches, they differ in their rigidity, macronutrient ratios, and overall philosophy.

What to Eat on a Modern Atkins Plan
What you can eat on Atkins depends heavily on which phase you're in (for Atkins 20) or your starting carb count (for Atkins 40). However, the general focus remains on a selection of high-quality foods:
- Proteins: Fish and shellfish, poultry, beef, pork, eggs, and cheese are staples.
- Healthy Fats: Monounsaturated and polyunsaturated fats from olive oil, avocado, and nuts are emphasized.
- Low-Carb Vegetables: Foundation vegetables like asparagus, broccoli, leafy greens, and peppers are included from the start.
- Added Variety (Later Phases): As you progress, nutrient-dense carbs like berries, legumes, and whole grains are gradually added back.
This modern, more balanced approach is a far cry from the earlier, stricter versions, giving dieters a much wider and healthier range of options.
