Keto Diet: How Keto Works on Atkins Weight Loss Plans | Atkins

Keto Diet—The Atkins® Way

The level of carb intake recommended in Atkins 20®* and Atkins 40® align them with ketogenic diet plans 1 that allow you to live a little, offering personalization and greater flexibility to provide a sustainable, long-term plan for getting healthy and staying healthy.

Get Started

We understand how the keto diet works and have over 40 years of experience getting people into fat-burning ketosis with more food choices and a greater balance of macronutrients. Ultimately, it’s a more realistic approach to classic keto. Learn more about the benefits of a flexible Atkins ketogenic diet.


How Does Keto Work for Weight Loss?

Ketogenic diets are low in carbs and high in fat (LCHF). This combination reroutes your metabolism to burn fat—instead of carbs and sugar—for fuel, which reduces fat stores in the body and encourages more efficient weight loss. 2

What is Atkins Keto?

Whereas a classic keto diet requires strict monitoring—and sometimes medical supervision—Atkins keto diets like Atkins 20®* and Atkins 40® have more flexibility with similar benefits. Our plans emphasize optimal servings of protein, in addition to healthy fats and low carb foods, to maintain muscle mass and keep you feeling full, not restricted. 3 And, since there’s more room for protein, you’ll have more food options to choose from and enjoy. On Atkins custom keto diets, you’ll stay on track to reach your weight goals with a variety of food choices, keto products, greater nutritional balance, and less rigidity.
